Important Safety Information

IMPORTANT! Read the following important safety instructions to avoid personal injury or death, and to avoid damage to the equipment or property.

WARNINGS (CONTINUED)

FOR INSTALLING PRESSURE AND TEMPERATURE RELIEF VALVES IN ACCORDANCE WITH AMERICAN NATIONAL STD. Z21.22-1979. Combination pressure and temperature relief valves with extension thermostats must be installed so that the temperature-sensing element is immersed in the water within the top 6" (152 mm) of the tank. They must be installed either in the hot outlet service line or directly in a tank tapping. Combination pressure and temperature relief valves that do not have extension elements must be mounted directly in a tank tapping located within the top 6" (152 mm) of the tank, and shall be adequately insulated and located so as to assure isolation from the flue gas heat or other ambient conditions that are not indicative of stored water temperature. TO AVOID WATER DAMAGE OR SCALDING DUE TO VALVE OPERATION, DRAIN PIPE MUST BE CONNECTED TO VALVE OUTLET AND RUN TO A SAFE PLACE OF DISPOSAL. Discharge line must be as short as possible and be the same size as the valve discharge connection throughout its entire length. Drain line must pitch downward from the valve and must terminate between 1-1/2" (38 mm) and 6" (152 mm) above the floor drain where any discharge will be clearly visible. The drain line shall terminate plain, not threaded, with material serviceable for temperatures up to 250°F (121°C) or greater. Excessive length, over 30' (9144 mm), or use of more than four elbows can cause a restriction and reduce the discharge capacity of the valve. No shut-off valve shall be installed between the relief valve and tank, or in the drain line. Valve lever must be tripped periodically to assure that waterways are clear. This device is designated for emergency safety relief and shall not be used as an operating control. The valves are set to relieve at 150 psi (1034 kPa) or when water temperature reaches 210°F (99°C). Read tag on valve for additional information.

To avoid any injury or damage, the booster heater must only be serviced by qualified personnel.

WARNINGS

Valves supplied by Hatco are designed for high temperature commercial operation. Do not substitute Hatco valves with valves designed for domestic water heaters.

Units are equipped with a High Temperature Limit Safety Switch that will shut the power off if the unit overheats. To avoid any injury to personnel or damage to the unit, contact an Authorized Hatco Service Agent if the High Temperature Limit Safety Switch cannot be reset or continues to trip.

To avoid personal injury and to assure safe operation install the booster heater as close as possible to the commercial dishwasher. Employ recirculation if distance between booster and commercial dishwasher exceeds National Sanitation Foundation (NSF) specifications of five (5) linear feet (1524 mm).

To avoid personal injury and avoid damage to the booster heater refer to BOOSTER HEATER SIZING CHART in this manual.

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.

This product has no “user” serviceable parts. To avoid damage to the unit or injury to personnel, use only Authorized Hatco Service Agents and Genuine Hatco Replacement Parts when service is required.

Genuine Hatco Replacement Parts are specified to operate safely in the environments in which they are used. Some aftermarket or generic replacement parts do not have the characteristics that will allow them to operate safely in Hatco equipment. It is essential to use Hatco Replacement Parts when repairing Hatco equipment. Failure to use Hatco Replacement Parts may subject operators of the equipment to hazardous electrical voltage, resulting in electrical shock or burn.
