Installation Instructions Section 2
2.1 RECEIVING
INSPECT SHIPMENT FOR POSSIBLE DAMAGE. All goods are carefully manufactured, inspected,
checked and packed by experienced workers. The manufacturer's responsibility ceases upon delivery of
goods to the carrier in good condition. Any claims for damage, shortage in shipment or non-delivery must
be filed immediately against the carrier by the consignee.
2.2 INTRODUCTION
With a great reputation of quality and reliability, Super Hot booster heaters can produce 180ºF rinse water
making dishware cleaner, odorless and safer. Compared with other methods of sanitizing, the Super Hot
Electric Booster is the economical choice, having high efficiency and using less detergent and rinse
additives. Super Hot booster heaters provide the best sanitation method for your dishware dishwashing.
2.3 CAUTION
1. Disconnect all power supplies to prevent electrical shock and damage to equipment.
2. Installer must be a qualified, experienced service technician.
3. Conduct a thorough checkout when installation is complete.
2.4 BOOSTER HEATER LOCATION
The space saving compact booster heaters can be installed
almost anywhere. The booster heater may be installed in an
enclosed space and attached directly to a combustible
surface, however, allow ample space for connecting,
disconnecting and servicing the unit. Locate booster heater
as close to dishwasher as possible. Dimensions are shown in
Figure 1.
Sturdy plated steel legs are standard, but stainless steel
hanging brackets for under counter suspension are also
available (specify when ordering), see Figure 2.
2.5 PIPING
Figure 2 – Optional Hanging Brackets
The recommended piping arrangement is shown in Figure 1.
Use copper tubing only. Install the pressure reducing valve (preset for 20 psi). Install the temperature
and pressure relief valve on the booster heater and plumb discharge in accordance with local codes. The
temperature and pressure gauge attaches to a tee on the inlet between reducing valve and booster
heater. It is mandatory that a diatrol expansion chamber and shock absorber be installed in the line
between booster heater and dishwasher (as close to dishwasher as possible). In addition, it is
recommended that the inlet and outlet lines be insulated to prevent heat loss and that unions be used for
piping connections to ease service.
All Super Hot booster heaters have 3/4" NPT inlet and outlet pipe size. Dielectric couplings should be
used in connecting dissimilar metals, such as galvanized to copper, to prevent electrolysis. A check
valve should not be installed in the supply line to the booster heater. All shut-off valves must be gate or
ball valves, not globe valves.
