Water Quality Requirements
Incoming water with hardness exceeding 3.0 grains per gallon (GPG) (0.75 grains per liter) must be treated and softened before being supplied to the booster heater(s). Water containing over 3.0 GPG (0.75 GPL) will decrease efficiency and reduce the operating life of the unit.
Note: Product failure caused by liming or sediment buildup is not covered under warranty.
Product Specifications
The Electric Booster Water Heater is manufactured for commercial use by Hatco Corporation, Milwaukee, WI 53234 U.S.A.
The booster is designed to supply the final 180°F (82°C) rinse for dishwashers. The tank is designed for a working pressure of 150 psi (1034 kPa) and hydrostatically tested at 300 psi (2069 kPa), featuring a Hatco Castone® lining.
The heater includes all internal plumbing, such as 3/4" NPT pipe and fittings for inlet and outlet. Controls are built-in, including contactors and pre-wiring in accordance with UL #1453 and 422.11 NEL 2002. A suitable surface mounting circuit breaker or fused disconnect switch must be provided by the electrical contractor.
Electric heating elements are metal sheathed and controlled by an ambient compensating immersion thermostat. The booster is protected with a high-temperature limit switch (ECO) and a low-water cut-off.
The heater features a stainless steel front and a silver-gray hammertone body, with standard 6" (152 mm) legs. Optional stainless steel body, base, and stainless steel adjustable legs are available.
The heater includes a temperature/pressure relief valve, a high-temperature pressure reducing valve with bypass, and two indicating temperature/pressure gauges.
Warranty: 24/7 parts and service assistance is provided for the US and Canada.
Certifications and Origin
The product is certified by UL, US, and NSF. It is manufactured in the USA.
