The booster heater should be installed in an area where leakage of the heat exchanger or
connections will not result in damage to the adjacent area or to lower floors of the structure.
When such locations can not be avoided, it is recommended that a suitable drain pan, adequately
drained, be installed under the appliance. The pan must not restrict combustion airflow. Never
install the booster heater directly over a floor drain or floor sink where steam from drain can be
ingested into the booster heater air intake.
The gas used with this unit must be of the type specified on the specification plate on this unit.
Never use any other than the specified gas
2. Access
To remove front panel, raise panel until bottom releases, tilt the bottom out and remove.
3. Electrical Connection Instructions
CAUTION: DO NOT TURN ON THE POWER SWITCH. The servicing technician performing
the Startup will make the booster operational
.
FAILURE TO FOLLOW THESE
INSTRUCTIONS MAY RESULT IN DAMAGE TO THE BOOSTER HEATER WHICH WILL VOID
THE BOOSTER WARRANTY.
The PrecisionTemp Gas Booster Heater operates on 115v AC, 15 amp, single phase current. All
internal electrical connections have been made at the factory. Follow local codes when installing,
specifying wire size breaker and conduit. In the absence of local codes observe the National
Electrical Code, ANSI/NFPA 70.
Power for the booster heater should be on its own 115v AC 15-amp single-phase GFI circuit.
Local electrical codes should be observed. The booster is equipped with a three-prong plug. Plug
into a 115v AC 15 amp GFI circuit. Be sure to route wire in a way that it is protected from
damage.
4. Plumbing
The PrecisionTemp Gas Booster Heater is designed to boost the rinse temperature in a
commercial dishwasher from the available hot water, ranging from 110°F to 140°F up to a 180°F
sanitizing rinse. Health Codes, NSF Standard #5 and local plumbing codes require that rinse
water be 180° F at the rinse nozzle.
For protection against excessive water pressure in the booster heater, the pressure protection
equipment supplied by PrecisionTemp must remain installed (refer to plumbing diagram). This
valve, installed on this booster heater, is constructed for commercial use and is not the same as
those used on domestic water heaters. It is manufactured with brass working parts and heat
resistant silicone seat discs especially designed for high temperature operation. This valve is
installed on a ¾” pipe tee close to the hot water outlet fitting of the booster (See installation
diagram).
For proper performance of the dishwasher and booster heater, install a pressure-reducing valve
ahead of the dish machine with a pressure setting of 20 PSI during the rinse operation. See
number 5 below
. IMPORTANT
. If there is already a functioning pressure reducer installed on the
warewasher, do not install another at the booster. This will cause variations in pressure improper
water flow.
Plumbing Installation
1. The booster heater recirculation tank should be installed as close as possible to the
warewasher. Provisions of NSF Code #5 should be observed and circulation methods
employed
. IMPORTANT
- The booster heater must be installed in a horizontal position
(base parallel to the floor and level by adjusting legs).
