INSTALLATION WARNING To assure proper operation and avoid a possible unsafe condition, the booster heater must be installed in a horizontal position with the base parallel to the floor and the inlet connection at the lowest point. WARNING FOR INSTALLING PRESSURE AND TEMPERATURE RELIEF VALVES IN ACCORDANCE WITH AMERICAN NATIONAL STD. Z21.22-1979.
INSTALLATION CAUTION To assure proper operation do not use an antisiphon or check valve on the incoming water line. BLENDED PHOSPHATE WATER TREATMENT SYSTEM (OPTIONAL) Hatco recommends that the Blended Phosphate Water Treatment System be installed with unions on the incoming 3/4" water supply line after the pressure reducing valve and before the booster heater.
INSTALLATION 2. Provide the inlet line with a shut-off valve, (a full opening gate or ball type), one temperature/pressure gauge, and the pressure reducing valve. Set pressure reducing valve at 20 psi (138 kPa) flow pressure. Inlet Refer to Figure 8, 9, 10, 11 or 12. 1. Connect the booster water inlet to a hot water supply line from the regular water heater. Water temperature from the regular water heater should be 110° or 140°F (43° or 60°C) and should not exceed 160°F (71°C).
INSTALLATION Temperature/Pressure Pressure Relief Valve 150 psi (1034 kPa)/210°F (99°C) Pressure Reducing Valve with Bypass 20 psi (138 kPa) flow pressure maximum Temperature/Pressure Gauge Discharge from T/P Relief Valve. Air gap must comply with plumbing code.

INSTALLATION Outlet Temperature/pressure gauge with 1/2" pipe thread 1. Using a 3/4" union and piping, connect the booster heater water outlet to the commercial dishwasher sanitizing rinse pipe connection. 1/2" copper female fitting adapter CAUTION To assure proper operation on all Large Compact Series units, (C-24 to C-57), do not turn or adjust outlet water connection. NOTE: Red mark on outlet water pipe for C-24 to C-57 series units must remain in the top most position.
INSTALLATION Electrical Connections ELECTRICAL-ALL SIZES AND VOLTAGES General 1. Remove the front jacket cover screws, pull the cover forward and remove the cover. Hatco Electric Booster Water Heaters are available for operation on standard power systems. Check the identification decal for the proper power supply. NOTE: On Imperial models, there is a hinged access panel under the front jacket cover. Remove the bottom screw and lift the panel up to expose the fuse blocks.
OPERATION SYSTEM START-UP WARNING Water in the unit is very hot. Wear protective gloves and proper attire when operating to avoid injury. 1. Close drain pipe valve. 2. Open Water 140°F 160°F shutoff valve to primary water supply. temperature at inlet should be 110° to (43° to 60°C) and should not exceed (71°C). Indicator Light Figure 17. Controls-Imperial and Compact Models NOTE: Minimum temperature differential between inlet and outlet should never be less than 20°F (11°C).
MAINTENANCE GENERAL WARNING To avoid any injury or damage to the booster heater turn the power OFF at the disconnect switch/circuit breaker and allow to cool before performing any maintenance or adjustments. THERMOSTAT Thermostat Adjustment The thermostat is factory calibrated to produce temperatures of 185°-190°F (85°-88°C). If adjustment or recalibration is required use the following procedure. (See Figures 18 and 19.) Access Cover Figure 18.
MAINTENANCE WARNING If service is required on this unit, contact your Authorized Hatco Service Agent, or contact the Hatco Service Department at 800-558-0607 or 414-671-6350; fax 800-690-2966 or International fax 414-671-3976. BLENDED PHOSPHATE TREATMENT SYSTEM (OPTIONAL) The Blended Phosphate Water Treatment System reduces mineral scale by introducing a measured amount of polyphosphate into the water. Cartridges supplied have a usage rating of 100,000 gallons (378,541 liters) of water.
ACCESSORIES STAINLESS STEEL ADJUSTABLE LEGS 1. Carefully place unit on its side. CAUTION Do not lay unit on the side with the control panel or damage to unit could occur. 2. Thread the adjustable legs into the existing leg holes on the bottom of the unit. (See Figure 21.) 3. After all legs are secure, return the unit to the upright position. Figure 21. Optional Stainless Steel Adjustable Legs NOTE: If unit is not level, use an adjustable openend wrench to adjust the foot of each leg until unit is level.
TROUBLESHOOTING WARNING To avoid any injury or damage, the booster heater must only be serviced by qualified personnel. 4. Booster heater voltage must be correct for voltage available. Check nameplate on the booster heater for full information. 5. Water pressure at the inlet to the booster heater must be adequate for proper operation of the rinse cycle of the dishwasher, not to exceed 20 psi (138 kPa). Check with dishwasher manufacture for specific details.
TROUBLESHOOTING WARNING To avoid any injury or damage, the booster heater must only be serviced by qualified personnel. SYMPTOM Water reaches 180°F (82°C) but does not last through the entire dishwasher operation. The booster heater does not heat at all or only delivers water at 120°-150°F (49°-66°C). WARNING To avoid any injury or damage to the booster heater turn the power OFF at the disconnect switch/circuit breaker and allow to cool before performing any maintenance.
TROUBLESHOOTING WARNING To avoid any injury or damage, the booster heater must only be serviced by qualified personnel. SYMPTOM Water at dishmachine is not at the proper temperature. Heating elements burn out. WARNING To avoid any injury or damage to the booster heater turn the power OFF at the disconnect switch/circuit breaker and allow to cool before performing any maintenance. PROBABLE CAUSE CORRECTIVE ACTION Gauge(s) not working properly.
TROUBLESHOOTING WARNING To avoid any injury or damage, the booster heater must only be serviced by qualified personnel. SYMPTOM High temperature limit trips. WARNING To avoid any injury or damage to the booster heater turn the power OFF at the disconnect switch/circuit breaker and allow to cool before performing any maintenance. PROBABLE CAUSE CORRECTIVE ACTION Temperature limit set too low. If booster heater is not overheating, replace High Limit Safety Switch. Thermostat set too high.
