Resumen del manual
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. Unit is not weatherproof. For safe and proper operation the unit must be located indoors where the ambient air temperature is constant and is a minimum of 70°F (21°C). CAUTIONS 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. If water supply pressure to the booster inlet is over 20 psi (138 kPa) during flow, install Hatco pressure reducing valve with built-in bypass, Hatco part number 03.02.004.00, for proper operation of dishwater rinse nozzles. NOTE: The pressure reducing valve must be the type equipped with a high pressure bypass as supplied by Hatco. Do not turn on power to the booster heater until the tank has been filled with water and all air has been vented through the dishwasher rinse nozzle. The heating elements will burn out in seconds if operated when they are not immersed in water. To assure proper operation on all Large Compact Series units, (C-24 to C-57), do not turn or adjust outlet water connection. CAUTIONS To prevent electrolysis or plumbing damage dielectric couplings should be used in connecting dissimilar metals, such as galvanized to copper. To avoid possible leaks, do not back out or loosen any pipe fitting. Do not lay unit on the side with the control panel or damage to unit could occur. To avoid damage to the unit always drain the booster heater with power to the unit off, or element burnout could occur. Incoming water in excess of 3 grains of hardness per gallon ([GPG] .75 grains of hardness per liter [GPL]) must be treated and softened before being supplied to booster heater(s). Water containing over 3 GPG or .75 GPL will decrease efficiency, increase energy use, and reduce the operating life of the unit through increased lime build-up. Product failure caused by liming or sediment buildup is not covered under warranty. To assure proper performance Hatco Electric Booster Water Heaters are only to be connected to the same power supply as indicated on the specification decal. Units connected to an incorrect power supply voids the product warranty and may damage the equipment. 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. 3 Form No. EBOOSTERM-0406 MODEL DESCRIPTIONS ALL MODELS Hatco Electric Water Booster Heaters are available in three models: Imperial, Compact and Mini- Compact. All standard models include a booster heater with low-water cut-off system, temperature/pressure relief valve, pressure reducing valve with built-in high pressure bypass, two temperature/pressure gauges and a high temperature limit safety switch. IMPERIAL MODELS “S” SERIES Hatco Imperial models feature a Castone® tank with a 10 year limited warranty, an ON/OFF switch, an indicator light and 6" (152 mm) legs. Imperial units have a capacity of 16 gallons (61 liters) and provide up to 573 gph (2169 lph) of sanitizing rinse water based on a 40°F (22°C) temperature rise. COMPACT MODELS “C” SERIES Hatco Compact models feature a Castone® tank with a 10 year limited warranty, an ON/OFF switch, an indicator light and either 6" (152 mm) legs or slide mounting brackets for mounting under a dish table. Compact units have a capacity of 6 gallons (23 liters) and provide up to 573 gph (2169 lph) of sanitizing rinse water based on a 40°F (22°C) temperature rise. MINI-COMPACT MODELS “MC” SERIES Hatco Mini-Compact models feature a stainless steel tank and 6" (152 mm) legs. Mini-Compact units have a capacity of 3.2 gallons (12 liters) and provide up to 114 gph (432 lph) of sanitizing rinse water based on a 40°F (22°C) temperature rise. Ideal for either hot water sanitizing or point-of-use hot water dispensing. Figure 1. Imperial Model Figure 2. Compact Model Figure 3.
