5 REFRIGERANT RECOVERY Refrigerant Certification and Recordkeeping May 13, 2015 As required by Section 608 of the Federal Clean Air Act, all persons involved in work which involves refrigerant, the access to a sealed refrigeration or air conditioning system, or the disposal of equipment containing refrigerant must have the appropriate Environmental Protection Agency (EPA) certification. There are (4) four categories of technician certification: TYPE I TYPE II TYPE III UNIVERSAL Persons who maintain, service, or repair small appliances, i.e., refrigerators, freezers, window A/C units, dehumidifiers, under-the-counter ice makers, vending machines, and drinking water coolers. Persons who maintain, service, repair, or dispose of high pressure appliances, i.e., conventional split system heat pump and air conditioner systems. Persons who maintain, service, repair, or dispose of low pressure appliances, i.e., chiller systems. This classification indicates that the individual is certified in all of the abovementioned categories. CERTIFICATION RECORDKEEPING The Community Manager shall be responsible for the recordkeeping and archival of certification documents, and shall ultimately be responsible for compliance with all the requirements of this policy. 1. For each current employee who is certified, the Community Manager shall complete the following: a. Confirm a legible copy of the employee s certification card is filed in the Refrigerant Recovery Log Book. b. Post a scanned copy onto the Benchmark X-Drive in the Employee Certification Cards folder. c. Forward a scanned copy of current and/or updated certification cards to Benchmark s Human Resources Director. 2. For former employees, if certification cards are available, the Community Manager shall file a legible copy of certification card(s) in the Refrigerant Recovery Log Book and post a scanned copy onto the Benchmark X-Drive in the Employee Certification Cards folder. 3. For any employee who has come from another Benchmark community and has completed any service request dealing with refrigerant or the disposal of appliances containing refrigerants while at the community, the Community Manager shall post a scanned copy onto the Benchmark X-Drive in the Employee Certification Cards folder.
6 GENERAL RECORDKEEPING In accordance with the Environmental Protection Agency (EPA) recordkeeping requirements, the Service Manager shall maintain the information listed below and ensure the documentation is being completed timely and accurately by all service team members. As such, the Service Manager shall maintain the following: 1. Documentation for the service, maintenance, repair, or disposal of appliances which contain refrigerant. a. Documentation shall include refrigerant tracking logs, appliance disposal forms, service requests in OneSite, and OneSite invoices for the purchase of refrigerants and appliances containing refrigerants. b. Digital information in OneSite is sufficient documentation; no additional paper hardcopy is required to be saved or filed. 2. Records indicating the specific equipment or appliance containing refrigerant which was serviced, maintained, repaired, or disposed. 3. Records indicating the amount of refrigerant used during the service, maintenance, or repair of each specific system or appliance containing refrigerant. 4. Records indicating the amount of refrigerant recovered or recycled during the service, maintenance, repair or disposal of any system or appliance containing refrigerant. 5. A copy of each receipt or invoice for the purchase of any refrigerant. a. Digital information in OneSite is sufficient documentation; no additional paper hardcopy is required to be saved or filed. 6. Maintain and monitor the Refrigerant Recovery Logs as needed for completeness and accuracy. 7. Periodically verify the weight of refrigerant cylinders which are in use, and confirm the tracking log is up to date and accurate. a. These periodic checks shall occur at least every 30 days during the air conditioning season or heat pump heating season when refrigerants have been used or recovered. 8. Upon delivery of a refrigerant cylinder to the community, clearly label the cylinder with a unique number, weigh the refrigerant, and log the corresponding weight into the refrigerant tracking sheet. a. Typically, the date the cylinder was delivered is used as the unique tracking number, followed by an additional letter or number if multiple cylinders are received on the same date. For example: 5/12/2015-A, 5/12/2015-B, etc. 9. Scanned copies of the Refrigerant Logs, Appliance Disposal forms, Accidental Venting Reports, and all other documentation in the Refrigerant Recovery Log Book shall be uploaded and posted onto the Benchmark X-Drive. a. Recurring service requests will automatically be generated in OneSite for these tasks. If these service requests are not automatically generated, post files monthly. b. Pages which have previously been scanned and posted onto the drive do not need to be re-scanned and re-posted.
7 10. As long as all EPA Log documentation has been scanned and properly posted onto the Benchmark X-Drive in the appropriate folders, and the files are named according to the current policy, log pages which are older than 12 months may be removed from the binder and destroyed. CERTIFIED EMPLOYEES 1. If required by Federal, State or Local code, certified employees must carry a wallet size certification card with them while handling refrigerant or when servicing or disposing of equipment which contains refrigerant. ALL EMPLOYEES 1. Special warning to all employees: any individual found venting refrigerant is subject to disciplinary action up to and including termination, in addition to any Federal, State, or Local fines which may be imposed.

Use non-acidic detergent coil cleaner to clean evaporator coil with high pressure water (don t bend fins) or non-acidic detergent for condenser coils. Evaporator coils are dirty before it shows. B. Proper heat passing through evaporator coils protects compressor from flood-back. C. Always let unit run for several minutes to stabilize before testing. D. As heat rises, pressure rises/as heat drops, pressure drops. E. Suction line pressure tells you about evaporator temperature. F. High side pressure tells you about condenser performance and restrictions. G. High ambient temperatures will cause suction line and liquid line pressures to increase. H. Super heat gives proper charge. I. Don t charge to correct low suction pressure until you check items in Suction Pressure Too Low. J. Low charge can be destructive to compressor, also because the super heated vapor cools compressor crankcase. K. Freon does not wear out or disappear. If you have to charge unit you have a leak to find. L. Always charge by Super Heat! 1. Read section Super Heat Charging. 2. Don NOT charge by: a. Feeling suction line. b. High side temperature 30 degrees over ambient temperature. c. Running amperage of compressor. Page 9
28 A/C Troubleshooting Guide 3. These don t allow for condition of evaporator and indoor ambient temperature or performance of condenser. M. Unit should maintain apartment at least 10 to 12 degrees below outside ambient temperature. Also, a unit running properly can only lower temperature about 1 degree per hour if unit is trying to overcome a hot apartment. N. If breaker trips periodically unit may be short cycling because of lack of familiarization of thermostat by resident. 1. Instruct resident of it s use. O. Sometimes short cycling can be eliminated by installing a time delay switch on 24 volt circuit before contactor. P. If system is evacuated, always add liquid line filter. (Freon is an excellent cleaner). Q. If system is evacuated after compressor burn out; flush system thoroughly to remove contamination; add liquid line filter and suction line filter (Freon is an excellent cleaner). Suction line filter should be removed after a few days. R. Be careful not to condemn compressor 40% of condemned compressors nationwide should NOT have been (Not our communities). S. If contactor is clicking or burned replace. T. Heat pump check: 1. High and low pressure switches. 2. Defrost controls. U. If resident has closed off room doors or supply registers: 1. Evaporator will be starved. 2. Suction line pressure will drop. 3. Possible compressor flood back. V. Remember, it is possible to have two or more problems at the same time. 1. Use the process of elimination; i.e. high suction pressure and low high side pressure sounds like compressor valve problem, but could be overcharged unit running on cold day. Do NOT overlook the obvious. W. If air conditioner is running properly for some time and apartment is still hot check for damage to attic insulation, loose ductwork or gap in plenum. Page 10

30 Compressor Check Guide Testing a Compressor for Electrical Shorts 1. Using an ohm meter, check for continuity between the common terminal and the compressor casing; check between the run terminal and the compressor casing; check between the start terminal and the compressor casing. If there is not a continuity reading, the compressor has grounded out and must be replaced. 2. Using an ohm meter, check for continuity between the common, run and start terminals and measure the amount of resistance in ohms. The ohm reading between common and run should be the lowest; between common and start should give the next lowest; and between run and start should be the highest. If there is no reading between terminals, then the windings have burned out or the overload is defective. The readings between common and run and between common and start should add together and equal the reading between start and run. **Generally, on 3 ton or smaller compressors, the ohm reading between start and run should not exceed 20 ohms. Compressor Terminal Diagram C (common) S (start) R (run)
31 CONDENSING UNIT REPLACEMENT INSTRUCTIONS For condensers which are being installed as replacements for condensers which are the same capacity and efficiency. 1. Disconnect all power to the unit. Lockout power sources and Tagout. 2. Follow the evacuation instructions at the end of this document and remove all refrigerant with appropriate recovery machine and practices. NEVER VENT REFRIGERANTS! 3. Study the installation instructions supplied with each new condensing unit. All items are important, but careful attention should be given to the electrical and refrigerant line data tables. 4. Remove old condensing unit, retaining all of the original tubing and electrical wiring possible. 5. If the remaining portion of the liquid or vapor lines contains a line drier, remove and discard. 6. If this new unit replaces one with a burned compressor, careful attention must be given to cleaning the refrigerant lines, evaporator coil, and capillary tubes or expansion valve. a. Use a flushing agent such as ProFlush per manufacturer s directions. b. With a capillary tube system, a vigorous purging with dry nitrogen through the vapor line out the liquid line (backward purge will be helpful. c. If the evaporator coil is equipped with an expansion valve, either remove the internal cage assembly or the complete valve prior to purging with dry nitrogen. Also confirm that the expansion valve is recommended for use with R-22. If not, replace with a proper type valve. 7. Place the new condensing unit on a level concrete base or plastic condenser pad. 8. Install a new liquid line filter drier in the liquid line external to the condensing unit. If replacing a unit with a compressor burnout, also install a suction line filter drier in the suction line. This suction line filter will need to be removed after several days of use (typically 30 to 60 days). 9. Protect the service valves from excessive heat by wrapping with a wet cloth, and then braze the refrigerant lines to the condensing unit using silver solder while allowing dry nitrogen to flow through the lines. 10. Pressurize only tubing and evaporator coil with dry nitrogen. Use sufficient pressure to assure an accurate leak test. DO NOT exceed the test pressures marked on the unit rating plate. WARNING: D0 NOT USE OXYGEN OR COMPRESSED AIR to purge refrigerant lines, or pressurize the system, or to check for leak. Oxygen can react violently with refrigerants and oils which can cause an explosion resulting in severe personal injury or death. 11. Inspect all joints and check for leaks using a liquid detergent or other leak detection fluid. If leak is found, release pressure and repair. 12. Follow evacuation instructions at the end of this document to remove all nitrogen and noncondensables from the system.
32 13. Add refrigerant to the system by weighing in the charge per manufacturer s specifications, or by releasing the pre-charged refrigerant from the condenser into the lineset by opening the liquid line service valve. 14. Ensure both service valves are open before placing the condenser into service. 15. Consult this wiring schematic and follow the installation instructions for electrical wiring. a. CAUTION: If the refrigerant is metered to the cooling coil by an expansion valve (TXV), the recommended size start relay and start capacitor must be correctly installed in the appropriate circuit. (NOTE: Units incorporating scroll compressors do not require start components.) 16. Clean or replace return air filters. Start the indoor blower with fan switch to "on position and check air flow for correct CFM through the cooling coil. 17. Turn thermostat sub-base switch to the cooling position. Operate the thermostat to call for cooling. 18. With the new unit in operation, balance the refrigerant charge after 30 minutes of running time with the use of the SUPERHEAT CHARGING METHOD or the SUPERHEAT CHARGING METHOD" instructions included with the unit. 19. Replace service valve caps tightly to prevent leaks. 20. Clean work area, log refrigerant usage. 21. Return after a few hours of operation or in the following days to confirm proper operation and refrigerant charge. EVACUATION: An evacuation of any system component that has been exposed to atmosphere or has lost its charge is essential before charging with refrigerant R-22. CAUTION: Compressors should never be used to evacuate the air conditioning system. Placing a compressor into a vacuum can cause internal electrical arcing resulting in a damaged or failed compressor. Only use the compressor to reduce pressure to 0 PSIG (atmospheric pressure) 1. Since the condensing unit itself will not have to be evacuated unless it has lost all its charge, leave the vapor and liquid line shut-off valves closed. 2. Use a refrigeration type vacuum pump capable of evacuation to 30" of mercury. 3. Connect a gauge set to the vacuum pump and to both the vapor and liquid line service ports. 4. Evacuate the system until the pressure gauge should read at least 29.5 of mercury, and then continue to run the vacuum pump for 15 to 20 minutes. 5. Turn off the vacuum pump and record the gauge reading. Wait 15 to 20 minutes to confirm the pressure doesn t change over this period of time, which would indicate moisture in the refrigerant oil.
33 6. The tubing and cooling coil will now be free of non-condensables and the liquid and vapor shut-off valves can be opened. 7. Do not remove the manifold and gauge assembly, as it will be needed to balance the refrigerant charge. 8. WARNING: THE BRASS VALVE IS NOT A BACKSEATING VALVE. OPENING OR CLOSING VALVE DOES NOT CLOSE THE SERVICE PORT. EXTREME CAUTION MUST BE EXERCISED NOT TO FORCE VALVE STEM AGAINST THE RETAINING RING. IF THE VALVE STEM IS BACKED OUT PAST THE RETAINING RING, SYSTEM PRESSURE COULD FORCE THE VALVE STEM OUT OF THE VALVE BODY AND POSSIBLY CAUSE PERSONAL INJURY. IN THE EVENT THAT THE RETAINING RING IS MISSING, DO NOT ATTEMPT TO OPEN THE VALVE.
