3 PLEASE NOTE: This Operations Manual should always be stored in the black box at the rear of the unit. unit.. T This is the left storage box as viewed while facing them. START-UP INSTRUCTIONS 1. Please read this Operations Manual completely prior to hooking the unit to machine that will be pulling it. 2. Unbolt the Blue Room Door. Remove shipping material on both "Danger Live Track" signs. 3. You will need an air jumper hose. Connect the hose between the machine that will be pulling the toilet cart and the air reservoir located under the water tank. Do not connect air line to any brake circuit. Air MUST be supplied to air reservoir when unit is in service. Check air gauge on side of unit. It should read 60 PSI. 4. Turn on the water tank, shut-off valve. Located under the water reservoir. 5. Flush toilet (valve located on left side of toilet on back inside wall of Blue Room) four times, waiting twenty seconds between flushes. This will assure there is sufficient water flowing through the toilet. When flushing, hold flush button down for approximately 2 seconds and assure the flapper is open prior to releasing the button. 6. Check that water level in bowl is at least two-thirds up from bottom of flapper. Water seal of flapper does not require complete submersion as flapper seal gasket provides complete hopper seal. The performance of the flush action will be improved by using an ample amount of water in the toilet bowl prior to flushing human waste and toilet paper. 7. Fill water tank, using city water, if possible. Well water that has not been treated may cause algae to form in the tank. 8. This unit is shipped with 4 each chlorine tablets in the blue chlorinator. In addition, the toilet cart is shipped with the following: 12 chlorine slugs; 12 rolls of toilet paper; 2 Micro-clean toilet cleaner; 2 hand sanitizer cartridges; 1 gallon Micro-Culture. 9. To order consumables and parts, a parts list is on the side of the black box at the rear of the unit. The list is also shown on page 13 of this manual. 10. If you have questions regarding start-up, please contact Don Gilstad at (office), or (cell)

4 Water-Loo Portable Railroad Toilet Operations Manual The purpose of this manual is to familiarize you with the operation and proper maintenance of the Water-Loo portable toilet system. This system offers a completely odor free and environmentally safe treatment process to safely dispose of human waste. The system requires only water in the reservoir, chlorine tablets in the chlorinator and an air supply that is regulated to 60 psi. Unlike other portable toilets, it s treatment tank eliminates the need to pump out a holding tank. Toilet Components and Operation Sequence Below are descriptions of the system s main components, as well as it s basic function: Toilet Bowl, equipped with a tube installed around the rim for washing the bowl Rim Wash Tubes: These tubes are removeable and used to provide a washing action through a series of.055 inch diameter holes on the underside of the tube. There is also an oval opening at the end of the tube that must be free flowing as well. Toilet Lower Chamber that retains the waste, before it is forced into the Treatment Tank with air pressure Flapper in the bowl, which is equipped with a replaceable gasket providing a seal so water will stand in the bowl when not in use. (The flapper s opening and closing operation is controlled by the A/W Sequence Valve.) (Note: the replaceable gasket must be checked fairly often to be certain that it is secured and not torn or degraded. Gasket part no is secured with a high quality self-adhesive, and when the old gasket is completely removed, be sure that the flapper face is cleaned well allowing proper adhesion for installation of the new gasket.) Air/Water Sequence Valve controls the sequence of operation by controlling the air flow to open and close the bowl flapper to control the flow of water, and to time the flow of air that charges the lower toilet chamber to then move waste to the treatment tank. Toilet Function: 1. After human waste enters the Microphor Air Operated Toilet and the toilet is flushed, the flapper at the bottom of the bowl opens, initiated by the A/W sequence valve and allowing wastewater to flow into the hopper. Clean water enters to rinse the bowl rim through the rim wash tube. 2. After 7-8 seconds, the flapper closes and clean water continues to flow into the bowl where it remains until the next flush 3. When the flapper has closed, compressed air enters the hopper, pushing the waste through the waste line into the Treatment Tank. CAUTION NEVER try to force open the flapper when the system is pressurized with air, as it will cause serious damage. To open the flapper, the air line must be disconnected and the air tank drained, then flush the toilet several times until it no longer cycles and the flapper hangs down in an open condition. Flapper opens and dumps water into toilet lower chamber. Flapper closed & waste & water rests in the toilet lower chamber A/W Sequence Valve initiates a discharge of air into the lower chamber & forces waste & water into black treatment tank

5 Toilet Requirements: Usage: Maximum of 80 flushes per 24 hour period Air: Supply compressed air at 60 psi at the toilet. Water: Gravity fed from upper level mounted water reservoir Flush Activator: Rear wall of blue room Air/Water Valve: The air and water (A/W) sequence valve is the air controlled valve that operates the toilet. The valve is mounted at the rear of the toilet stool where the water line enters the stool. Air/Water Sequence Valve Operation The air and water sequence valve is critical to the efficient operation of this toilet. It is located at the rear of the toilet where the water line from the reservoir enters the toilet. The A/W sequence valve can be accessed after removing the sheet metal panels at the rear of the toilet. The A/W sequence valve is equipped with a brass, adjustable needle (timing) valve that is at the right rear of toilet (viewed when facing toilet). The following demonstrates it s operation

6 Air & Water Sequence Valve Air In (60 PSI) 1. In the normal rest position, pressurized air enters the Flush Activator and goes from Flush Activator Port 1 (green tube) to Air/Water Sequence Valve Port 2, through Port 3 (red tube) to Air Cylinder Port 4 holding the Flapper closed, sealing the water in the bowl and maintaining a proper water surface area. Air Cylinder Water In Flush Activator 2. When the Flush Activator is pressed, air is shifted to Port 5 (blue tube) to A/W Seq. Valve Port 6 and on to Air Cylinder Port 8 (white tube). The air in the base of the Air Cylinder is bled off through Port 4 (red rube) to Port 3 and out Vent [1], allowing the Air Cylinder to retract, opening the Flapper. Simultaneously, pressurized air in the base of the A/W Seq. Valve pushes the piston and spool assembly up to open the water passage, allowing water to enter and rinse the bowl. The air on the top of the piston is bled off through Port 1 and out Vent [2] As the Flush Lever is released, the Flush Activator returns to the normal rest position redirecting pressurized air to Port 2, Port 3 and Port 4. The Bleed-Off Plug [12] bleeds off the air (black tube) under the piston, causing the spool to move downward, gradually closing the water passageway. The air having been bled off the top of the Air Cylinder Port 8 (white tube) through the end of the Flush Activator Vent [2] (blue tube), allows the Air Cylinder to close the Flapper allowing water to accumulate in the bowl, restoring a proper water surface area. 4. Near the bottom of the piston stroke, the air passageway from Port 10 (yellow tube) to the Hopper Port 11 is unblocked for 4-11 seconds to pressurize the hopper and expel the waste contents over the trap and into the waste line. 5. As the A/W Seq. Spool reaches the bottom position, the water supply is shut off, completing the flush cycle In the event of air supply failure, the spring in the Air/Water Sequence Valve maintains the valve in the closed position, blocking the water passageway. The flapper will open and allow water in the bowl to flow into the hopper forming a water seal

7 Troubleshooting the A/W (Air-Water) Sequence Valve If the fushing action of the toilet operation becomes erratic, it is likely there is a problem with the A/W Sequence valve. Most all A/W sequence valves use a brass, adjustable needle (timing) valve. Some older A/W sequence valves are equipped with a bleed plug which is simply a fixed orifice fitting. If this is experienced, the following are trouble shooting tips that can be used. 1. If the flush button sticks when depressed or released, apply silicone lubricant onto the shaft, and press in and out until free. 2. If the toilet bowl flapper stays open and does not close normally, try to (a) clean and lubricate the air cylinder rod until it moves freely or (b) clean or replace the bleed plug or adjust the needle valve on the sequence valve. Test to see if the flapper is moving freely after completely draining the air pressure from the toilet, and flushing 3 or 4 times until the flapper no longer operates. If the flapper assembly does not operate freely, replace the air cylinder. Clean or replace Bleed-Off plug, or adjust the Needle Valve on the Sequence Valve. 3. If the toilet bowl flapper opens and closes too quickly and doesn t allow a complete flushing to occur, check for the following: a. possible air leaks b. if equipped with a bleed plug, possible wear or damage to the bleed plug replace if necessary c. the A/W sequence valve may be out of adjustment, see page 14 for toilet troubleshooting chart. Overtightening of the Needle Valve may have damaged valve seat, not allowing proper adjustment, replace with new Timing Adjustment Assembly, P/N Treatment Tank Function In the treatment tank, human waste (solids & liquids) and toilet tissue paper is broken down by naturally occurring bacteria, into liquid and gas. The gas escapes out the tank vent. The liquid then flows through the filters to the bottom of the treatment tank, then into the chlorinator which will neutralize the liquid. The chlorine treated liquid then flows through the bottom of the holding tank and drips out of the discharge outlet tube at the back wall of the tank. NOTE: Microphor recommends adding a cup of Micro Culture monthly to insure proper operation. CAUTION: DO NOT remove the top inspection cover and probe into the Treatment Tank with any type of bar or stick as damage WILL occur to the filtering towers in the tank

8 Airline Components Functions The Air Filter-Regulator (left bowl) removes moisture and dirt from the air line to the toilet to prevent damage. Regulator is preset to 60 psi of pressure. The Air Line Lubricator (right bowl) adds a small amount of lubricant to the air system to help lubricate the air operated moving components of the toilet. Use a silicone oil P/N to replenish the supply of oil in the lubricator. Oil can be added by unscrewing the bowl from the lubricator assembly. A check should be made periodically to determine if there is enough oil to lubricate the toilet parts. The oiler should be adjusted to add one drop of oil per flush. Adjusting the oiler requires 2 people, one inside to flush the toilet valve and the other outside to adjust the brass screw on the lubricator. The slotted adjustment screw is located on the top of the oiler. Turning clockwise decreases the amount of oil, and counterclockwise increases the amount of oil. CAUTION: Make sure the air supply is shut off and reservoir drained before the air line lubricator is opened to fill with oil. Oil Dispensing Adjusting Screw Toilet Hopper Components Shown here, left to right to left are the following components: Top Row: 1. Hopper Top w/ Flapper, P/N Hopper, bottom only, P/N Hopper, complete, P/N (does not include air cylinder) 4. Crank Assembly only, P/N Air Cylinder, P/N Flapper Assembly only, P/N Hopper O-Ring Seal, P/N Note: These are Microphor part numbers

9 The Chlorinator The chlorinator is located next to the treatment tank and holds chlorinating slugs. The bacteria in the wastewater flows into the secondary chlorinator, allowing the chlorine sufficient time to kill the bacteria. The chlorinator should be filled as full as possible with chlorine slugs while making a tight seal. Consumption of chlorine is dependent upon frequency of use of the system. Use Microphor Chlorinating Slugs (P/N/ 94135). Microphor uses a unique binding and shape in their tablets and claim a slower dissipation rate than swimming pool tablets. Using the Microphor product will result in having to replenish the chlorinator less frequently and is required for warranty coverage. Lubricate chlorinator lid O-Ring with silicone oil before replacement. Chlorinator Filling Instructions Maintenance and Safety Procedure 1. Scissors are provided to cut the top of the chlorine slug package open to prevent injury from handling slugs or exposure to bag contents. 2. Microphor recommends using rubber gloves and goggles or a face shield. High ambient heat can cause higher levels of chlorine vapor and may require the use of a respirator, depending on ventilation at chlorinator. (Refer to Material Safety Data sheet MSDS). 3. Inspect chlorinator for chlorine slugs by pressing downward on cap while turning counter-clockwise ¼ turn and then lift cap off very slowly. If water is seen coming out around the cap, replace cap immediately. Rectify blockage in outlet of system. 4. If chlorinator is full of slugs, replace cap by placing on the chlorinator body and, while pressing down, turn clockwise until locking lugs on cap engage chlorinator and it is sealed. 5. If slugs must be added, make sure any residual chlorine at bottom is not blocking opening on lower portion of chlorinator. If residual chlorine is caked, carefully probe with a screwdriver or similar tool to break up. 6. Add slugs until chlorinator is full. Lay slugs flat, one on top of another, not on their edges. Refill as much as possible with slugs, but do not overfill, as this will put undue pressure on cap and possibly cause damage to packing of slugs

10 7. The chlorinator unit is designed to hold slugs and seal off chlorine odors. Inspect the unit carefully to make sure rubber cap seal or o-ring on chlorinator body is in place and is lubricated with silicone lubricant only. Inspect hoses, clamps, etc. to make sure they are tight and in good condition. 8. Chlorine is highly corrosive, causes skin and eye damage, is irritating to nose and throat and may be fatal if swallowed. Avoid breathing dust or vapor. 9. ENVIRONMENTAL HAZARDS: Chlorine is toxic to fish. Do not dispose into lakes, ponds, streams, estuaries, oceans or public waters unless this product is identified and addressed in a NPDES permit. For guidance, contact the regional office of the EPA. 10. PHYSICAL AND CHEMICAL HAZARDS: Strong oxidizing agent! Mix only with water. Do not add this product to any dispensing device containing remnants of any other product. Such use may cause violent reaction leading to fire or explosion. 11. STORAGE AND DISPOSAL: Keep this product dry in a tightly closed container when not in use. Store in a cool, dry, well ventilated area away from heat or open flame. Shelf life is one year from manufacturing date. Refer to MSDS for disposal. 12. PRACTICAL TREATMENT (First Aid): Eye/Skin Contact Flush with plenty of water for at least 15 minutes, while removing contaminated clothing and shoes. For eye contact seek immediate medical attention. If skin irritation occurs, seek medical attention. Inhalation Relocate to fresh air if signs of irritation or discomfort occur, take immediately to a hospital or physician. Swallowing If conscious, drink large quantities of water. DO NOT induce vomiting. Take immediately to a hospital or physician. If vomiting occurs, administer additional water. If unconscious or in convulsions, take immediately to a hospital. Secondary Chlorinator The secondary chlorinator is a contact chamber designed to hold wastewater long enough to give the chlorine an opportunity to kill the bacteria contained in the wastewater. This total bacteria kill allows the Microphor system to meet antipollution recommendations of the Association of American Railroads which exceed the requirements of the Food and Drug Administration. The waste water dripping from the pipe has been sterilized by the secondary chlorinator. Discharge Pipe - 9 -

11 Satellite Cabana (Blue Room) General Toilet Enclosure: The Satellite brand cabana (Blue Room) is double walled and has a toilet paper dispenser, hand sanitizer dispenser and LED interior lighting mounted on the interior walls. A coat hook is also provided on the inside of the door, as well as hover handles for support while straddling the toilet. Toilet Paper Rolls: The toilet paper dispenser holds two 9 inch rolls of tissue paper. To replenish the tissue paper rolls, place the key into the top of the dispenser and push down until the cover opens. To prevent motion of railroad toilet from unrolling tissue, slightly squeeze tissue roll to make center cardboard core oblong. Hand cleaning dispenser can be replenished by pushing up on tab at bottom front of dispenser. Replacement cartridges are available from Satellite, part number It is important not to neglect it s condition, but to keep the replaceable cartridge in it s proper location. Toilet Paper Dispenser Toilet Paper Dispenser Key Hand sanitizer dispenser Hover Handle Night Lights Air Supply Regulator & Lubricator: The microphor toilet requires the air regulator to be set at 60 psi of compressed air to operate properly. Air is supplied to the unit via the connection shown below. Typically the unit is towed by a host piece of equipment and the compressed air is supplied by the host machine. Compressed air is conveyed to the toilet unit through a check valve and air reservoir. On a daily basis, the moisture ejection valve (activated by pulling cable) on the host machine and toilet cart air reservoir must be activated to drain out any moisture accumulation

12 Water Supply Reservoir: The water supply reservoir consists of a 125 Gallon poly tank that should provide approximately 500 flushes. The reservoir is filled with water during normal work where freezing temperatures are not expected. If algae is present, the water reservoir must be drained and flushed and refilled with good quality water. Do Not use dirt contaminated, pond or well water that is not drinkable as this will accelerate the growth of algae in the water reservoir. Water contamination with algae will have a negative effect on the overall toilet operationand performance of the system, causing potential restrictions in the A/W Sequence valve and the Rim Wash Tubes. Winterizing: Cold weather requires the water system to be protected against freezing. Microphor recommends that propylene glycol be added to the water supply to prevent freezing (Dow Corning PG USP/EP). For a local dealer, go to An alternative source for the Propylene Glycol is from Barton Solvents in Council Bluffs, IA at Another alternative would include the Sierra brand automobile anti-freeze, but is generally a little more expensive than the food grade propylene glycol. The anti-freeze concentration levels required to meet various temperature thresholds is noted below. Propylene Freeze Anti-Freeze Glycol Water Protection % (Gals) (Gals) o + 12 F 30 % o F 40 % 4 6 o - 27 F 50 % orf 60 % 6 4 Note: Never use ethylene glycol based products in place of the required Propylene Glycol, as the alcohol based products will shut down the bacteria action when flushed into the treatment tank. Never use the Propylene Glycol products that are advertised for use in RV systems, because these products will tend to form a slush that will not pass through the toilet valves. Toilet carts that are stored over the winter should either be drained or protected with a -40 F mix of antifreeze to water. If you choose to drain the system, do the following: 1. Remove water reservoir lid and replace after the tank has been drained. 2. Remove the drain plug under the water tank. Leave the plug out and store in the toolbox. 3. Flush toilet until no more water flows into the bowl and the bottom toilet chamber or hopper below the flapper is empty. 4. Check to make sure there is no water left standing in hoses or cavities that did not drain under the previously outlined steps. Note: Failure to protect the Microphor toilet system in freezing weather will result in the A/W Sequence Valve breaking. Cleaning the Toilet The toilet and blue room can be cleaned with water using a power washer. A better method would be to clean the toilet area with Microphor s Micro-Clean Organic Spray Cleaner, P/N or equivalent and then wash down the area with a hand sprayer. Note: Ammonia based products SHOULD NEVER BE USED. These sanitizers, like Lysol, Pine-Sol, Herzol, etc. can stop the biological action in the treatment tank. NEVER USE ANTI-BACERIAL PRODUCTS IN THE MICROPHOR SYSTEM

13 Unplugging the Toilet The system can only decompose human waste and tissue. Heavy paper towels will not decompose and will eventually clog the passages in the treatment tank. If the toilet becomes plugged, a standard plunger can be used to help unplug the unit. If the toilet is plugged, shut off the water supply and disconnect the air supply. Press the flush button several times to bleed off the air pressure. When the air pressure is out of the valve, the flapper in the bottom of the toilet can be pushed open. Add an ample amount of water to the toilet bowl to create slurry solution. Use the plunger as with any standard toilet. Recharge the toilet air system and flush the toilet after making sure the flapper is closed and sealed. Multiple flushes may be required. If this does not clear the toilet, the waste line to the treatment tank may be plugged. To clear the waste line remove flexible couplings at both ends and clear with a wire or flush with a stream of water. Unplugging thetreatment Tank If excessive amounts of toilet paper, anti-bacterial cleaning products or other unapproved items for use with the toilet have been used, the treatment tank will plug-up. Unplugging the tank will require the services of a portapotty service. The lid on top of the treatment tank has to be removed, water flushed into the tank and the tank pumped out several times until the top compartment is clean. DO NOT USE ANYTHING TO LOOSEN SOLDS IN THE TANK as the filters inside the tank will be damaged. If the filters come loose or bottom of the compartment is cracked, the treatment tank will have to be replaced. IF PUMPING IS REQUIRED, THE PUMP TRUCK OPERATOR SHOULD CALL DON GILSTAD FOR INSTRUTIONS BEFORE STARTING at or Wheels & Axles The hubs inside each wheel have inner and outer bearings which can be lubricated with general purpose grease. Lubricate with a grease gun through zerk located on each hub. Wheel hub with zerk Pivot Axle Stabilizing Shims Tow bar Safety Chain Hook-up Tie Down Locations There are tie down plates behind bumpers. Toolbox handle and padlock hasp for railroad padlock are located on both storage boxes at the rear of the unit. Treatment Tank Vent
