Plumbing Installation Instructions:
IMPORTANT INFORMATION:
•
Ensure all fitting installations comply with local plumbing and building codes.
•
The booster heater does not require a temperature and pressure (T&P) relief valve. A
T&P relief valve may be installed if required by county, city or state plumbing code.
•
Installations in the Commonwealth of MASSACHUSETTS and KENTUCKY require
a T&P relief valve.
•
When connecting to a plumbing system that utilizes Flex or PVC, a T&P relief valve
should be used as added safety.
•
Do not connect the unit directly to CPVC pipe. You must use at least three feet of
copper pipe prior to connecting to any CPVC connection.
•
WARNING:
Do not solder any pipes with the unit connected to the pipes. Doing so
will damage the flow meter and void your warranty.
•
Before energizing the heater, run water for a minimum of three (3) minutes and
verify that all air has been removed.
•
Installation of an air separator device is recommended for installations where air can
be easily introduced into the water system (i.e. Well water systems, lake pumps, and
other municipal systems).
•
A shut off valve MUST be installed on inlet side of unit. A shut off valve on the
outlet is recommended.
Typical JTX Plumbing Installation:
Piping:
•
Remove the sweat end of the dielectric fitting from the unit.
•
Sweat the pipe to the dielectric union.
•
Connect the union and pipe assembly to the unit.
IMPORTANT – Be certain to connect the outlet piping to the final rinse and not to the
wash tank.
•
Install water pressure regulator in the entering cold/warm water inlet line and adjust to
the pressure recommended by the dishwasher manufacturer. The pressure reducing
valve is adjustable from 25 to 75 psi. The set screw located at the top of the diaphragm
adjusts the pressure, turn clockwise to increase the pressure and counter-clockwise to
decrease the pressure.
•
Install the factory supplied in-line pressure and temperature gauges in the entering
cold/warm and existing hot water lines.
NOTE
: The temperature sensing element
must be in the water stream as shown below.
•
A shock absorber is recommended in the hot water outlet line to soften the water
hammer caused by automatic dishwasher solenoid valves.
