[. . . ] Electric Booster Water Heaters Imperial "S" Compact "C" Mini-Compact "MC" Series Installation & Operating Manual I&W #07. 05. 001. 00 This manual contains important safety information concerning the maintenance, use and operation of this product. Failure to follow the instructions contained in this manual may result in serious injury. If you're unable to understand the contents of this manual, please bring it to the attention of your supervisor. Do not operate this equipment unless you have read and understood the contents of this manual. Este manual contiene importante información sobre seguridad concerniente al mantenimiento, uso y operación de este producto. [. . . ] Proper operation of the commercial dishwasher rinse nozzles requires available water pressure at the rinse nozzle be between 15 and 25 psi (103 and 172 kPa) when nozzle is operated. If water pressure available to the booster heater inlet is over 20 psi (138 kPa), a pressure reducing valve must be installed in the hot water supply line to the booster heater and adjusted to deliver 20 psi (138 kPa) flow pressure. The valve supplied by Hatco with the unit, Hatco part number 03. 02. 004. 00, has a built-in high pressure bypass which prevents excessive pressure build-up as the booster heats up. Final adjustment required at time of installation. PLUMBING CONNECTIONS CAUTION To avoid possible leaks, do not back out or loosen any pipe fittings. CAUTION Do not connect the heater directly to a boiler or furnace coil or any other uncontrolled temperature source, or the thermostat could be damaged causing the unit to overheat. WARNING To avoid injury or damage to dishwashing equipment do not connect Hatco Electric Booster Water Heaters to domestic (consumer) dishmachines or other domestic utilized equipment. WARNING To avoid any injury or damage to equipment and to assure proper operation do not connect an expansion tank of any type to booster heater water lines. WARNING To avoid personal injury or damage to the unit aftermarket covers must not be placed on or over the booster heater. Doing so can cause temperature and moisture build-up resulting in premature failure and electrical shock. WARNING To avoid personal injury or damage to the Hatco Electric Booster Water Heater, only use plumbing material suitable for a minimum water temperature of 200°F (93°C). Materials used must meet National Sanitation Foundation (NSF) specifications and all local plumbing codes and regulations. 20 TEMPERATURE/PRESSURE GAUGES CAUTION Hatco requires that two temperature/pressure gauges, Hatco part number 03. 01. 003. 00, be installed to assure proper operation. Install one in the supply line before the pressure reducing valve and one in the outlet line as close to the booster heater as possible. This provides a visual check of the water temperature and pressure before and after the water heater. NOTE: If a check valve is installed and cannot be removed install a back pressure relief valve, Hatco part number 03. 02. 039. 00, set at 125 psi (862 kPa) on the incoming line between the pressure reducing valve and the inlet to the booster heater. EBOOSTERM-0406 INSTALLATION Inlet Refer to Figure 8, 9, 10, 11 or 12. 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). Minimum temperature differential between inlet and outlet should never be less than 20°F (11°C). NOTE: Refer to BOOSTER HEATER SIZING CHART for application information. WARNING To avoid personal injury and avoid damage to the booster heater refer to BOOSTER HEATER SIZING CHART in this manual. CAUTION To assure proper operation on all Compact Series Booster Heaters, do not turn or adjust inlet water connection on unit. Doing so will change the internal water flow.
