Follow instructions on the tag located on the Temperature and Pressure Relief valve to
avoid contact with hot water discharge and to prevent water damage from operation of the
valve.
Repair or alteration of the Temperature and Pressure Relief valve in any way is prohibited
by National Safety Standards and local codes. DO NOT PLUG THE RELIEF VALVE OR
INSTALL A SHUT OFF VALVE OR ANY OTHER RESTRICTION IN THE DISCHARGE
DRAIN LINE! The booster heater should be located as close to the dishwasher rinse valve
as possible. If the booster heater is installed more than 5 feet from the dishwasher rinse
valve, an optional rinse water re-circulation kit is available from Vanguard Technology and
must be used to insure a consistent water temperature of 180-degrees at the rinse valve
(Fig.6.).
NOTE: All water supply piping to the booster heater must be completely flushed of
all debris and flux residue before connection to the booster heater. Damage caused
by debris or aggressive flux residue will not be covered under warranty
If booster heater is installed in a closed water supply system, such as one having a
backflow preventer in the water supply line, means shall be provided to control thermal
expansion. Contact the water supplier or local plumbing inspector on how to control this
situation or call the factory.
