Warewashers FTN/FTP SERIES (PROTRONIC) INSTALLATION AND OPERATION INSTRUCTIONS (original instructions) Starting from Serial No.: 8655 1268 REV. 01.12.2010

GB IMPORTANT NOTES USE IN ACCORDANCE WITH REGULATIONS: The machine is an item of technical work equipment that is solely intended for use in a work environment. The machine is intended exclusively for cleaning dishes, plates, cups, glasses, cutlery, trays and baking sheets etc. Do not use for electrically heated cooking and heat conservation appliances. SAFETY: If a starch attack system is built in, the supplier must ensure compliance with all relevant safety rules and regulations, thus reliably preventing the concentrated detergent coming into contact with the skin or eyes! Ensure that the operator wears tight-fitting clothing to prevent trapping hazard by the conveyor. Never hose down the outside of the machine with a hose or high-pressure cleaner. The Attention symbol is shown beside instructions that are essential for safe operation of the machine. Please read these passages thoroughly. LIABILITY: Installations and repairs which are not carried out by authorized technicians, the use of parts other than original spare parts or any technical modification to the machine not authorized by the manufacturer will render the warranty set out in the standard conditions of sale invalid. IMPORTANT: This Instruction manual is written for machines with an operating direction from left to right. For machines with an operating direction from right to left, the same information applies but with opposite handling directions. Depending on the options and features of the machine, the indications on the display may vary. The display shown in this manual corresponds to a three-tank machine with prewash. MACHINE NOISE LEVEL: The machine noise level is 73 db (A) 2 01.12.2010 BA-21853-002-GB

B A BA-21853-002-GB 01.12.2010 7

GB 2. CONNECTION 2.1. ELECTRICAL CONNECTION Must be carried out by an authorized technician according to the national and local codes. For Australia: in accordance with AS/NZS3500.1 2.1.1. CHECKING Open the control box and take out wiring diagram from the inside of the door. The electrical supply must correspond to the data on the nameplate and the wiring diagram. Line fuses and cable cross section must comply with the requirements. Supply disconnecting device (main switch with emergency stop function) adjacent to the machine (if not built in). 2.1.2. CONNECTING Draw mains cable (H07-RN-F) through cable gland at the bottom of the control box rear panel. Connect wires to main terminals or to main switch (if built in). Tighten all terminal screws in the control box (they may work loose during transport). Tighten all cable glands. Note: EN 60 335 stipulates that the appliance must be connected to an equipotential conductor. The connecting screw ( ) is located at the rear of control box beside the cable inlet. 8 01.12.2010 BA-21853-002-GB

2. CONNECTION GB 2.2. WATER CONNECTION Must be carried out by an authorized technician according to the national and local codes. The machine must be operated with potable water. For water with an extremely high mineral content, an external dematerialization unit is strongly recommended. 2.2.1. GENERAL INFORMATION Connect water supply and drain pipes according to installation plan. Line strainer and air gap are fitted to the machine as standard. 2.2.2. FRESH WATER SUPPLY FOR RINSING DN 20 (3/4") Should be soft (up to 4 Clarke, resp. 0.5 mmol/l). Must be cold if condenser is fitted. Line flow pressure 1.5-6 bar at ~ 500 l/hr. Provide shut-off valve on site. 2.2.3. FRESH WATER SUPPLY FOR TANK FILLING DN 20 (3/4") Should be soft (up to 4 Clarke, resp. 0.5 mmol/l) and warm (50-60 C). Line flow pressure 1.5-6 bar. Provide shut-off valve on site. 2.2.4. DRAIN CONNECTION To be connected to site drain: Common drain DN 50 (HT pipe). Equip the floor drain of the scullery with an odor trap (siphon). BA-21853-002-GB 01.12.2010 9

GB 2. CONNECTION 2.3. STEAM OR HOT WATER CONNECTION Must be installed by an authorized technician and in accordance with local regulations. Note: On site, make sure that the pressures and temperatures for the heating medium given in the installation plan cannot be exceeded. 2.3.1. GENERAL INFORMATION Connect supply and return pipes according to installation plan. All connections are equipped with necessary fittings and valves as standard. 2.3.2. INSULATION All pipes should be insulated. Insulating material should be water, heat and shock proofed. 2.3.3. ADJUSTMENT OF MANUAL SHUT-OFF VALVE with flow reducer for steam and hot water supply The built-in manual shut-off valve is equipped with an adjustment device to limit the heating supply medium. A special tool is necessary for adjusting the valve-seat. The correct adjustment is very important, particularly for higher pressures, and therefore must be carried out by a HOBART-trained service technician before first run or when changes are made to the plant on-site. The optimum adjustment is achieved when the nominal temperature of the booster can just be held during continuous operation while the valve is opened to maximum. If the valve is opened too far, pressure shocks may occur when the solenoid valve closes. This could cause damage to the installation. If the valve is closed too far, the required heating-power cannot be achieved. 10 01.12.2010 BA-21853-002-GB

2. CONNECTION GB 2.4. EXHAUST CONNECTION The responsible ventilation engineer must be consulted with regard to connection. Please pay attention to notes on the service drawing. 2.4.1. EXHAUST PIPEWORK 10 cm Leave a distance (approx. 10 cm) between machine exhaust and site channel or connect special exhaust stack (option). Use additional ventilation fan, as the built-in ventilator has no compression. The volume of air to be evacuated from site has to be larger than the volume of air of the machine (see installation plan). To prevent corrosion damage, provide exhaust channel in stainless steel or synthetic material. In case of extremely low temperatures: Provide insulation and antifreeze shutter. CASE 1: With vent hood (available as an option from HOBART). Connected to site exhaust channel (see diagram). For suction values, see installation plan. 250 B C CASE 2: With vent hood (available as an option from HOBART). 250 A 200 Connected via horizontal piping to the outside (see diagram). With built-in additional fan (A). Provide a frost guard (B) (if required). Provide a self closing louvre (C) at the outlet (if required). The duct work should be made from CrNi or plastic material to prevent corrosion problems. A voltage-free contact is provided in the machine control box to control the external fan. BA-21853-002-GB 01.12.2010 11

GB 2. CONNECTION 250 E A D B 200 CASE 3: With vent hood (available as an option from HOBART). Connected via vertical piping to the outside (see diagram). With built in additional fan (A). Provide a frost guard (B) (if required). Provide a roof seal (D) at the duct work. Provide a cover (E) at the duct work outlet. The duct work should be made from CrNi or plastic material to prevent corrosion problems. A voltage-free contact is provided in the machine control box to control the external fan. 2.4.2. EXHAUST INTO THE ROOM min. 30 cm Only possible in connection with Heat Pump System and sufficient room ventilation. Avoid condensate damage by mixing exhausts from vent outlet of the machine, directly with room air (air distributor). 2.5. DISPENSERS For detergent and rinse aid Normally, dispensers and controls are delivered and installed by the detergent and rinse aid suppliers. Install dispensers, controls and containers in such a way that they are easily accessible, easily visible, easy to service and do not disturb machine operation. Connection (A) for rinse aid is provided on the rinse water pipe above the rinse booster heater (R 1/8" inside). Terminals (230 V~) are provided in the control box (see wiring diagram). A Note: Note: Note: Please see separate installation instructions. It is recommended that dispensers and their controls are not fitted directly to the machine! (Thermal insulation could be damaged.) Use only commercial detergent and rinse aid (suitable for professional and industrial operations). Please pay attention to the manufacturer's safety instructions. 12 01.12.2010 BA-21853-002-GB
