Section 7, Plumbing the System
7-2
The POLAR™ HD Heating Module
•
Ensure a four (4) quart minimum overflow bottle is attached to
the filler neck.
•
The return and supply coolant plumbing connections are on the
top of the POLAR™ HD Heating Module and are 1/2” male NPT
fittings. The return coolant input to the POLAR™ HD Heating
Module is a connection labeled “Inlet” and the supply coolant
output from the POLAR™ HD Heating Module is a connection
labeled “Outlet”. Ensure proper direction of flow. Refer to Figure
7-1: Heating Module for the location of the fittings.
•
Two 1/2” NPT pipe to 3/4” hose barb fittings (not supplied) must
be fitted into the POLAR™ HD Heating Module connections and
tightened to a leak free condition using an appropriate thread
sealant.
•
Hose and/or tubing used to connect to the POLAR™ HD Heating
Module or Distribution Module input and output connections must
be heavy duty heater hose, minimum 3/4” I.D, or 5/8” PEX.
All fittings on the POLAR™ HD Heating Module require two wrenches
when tightening. One wrench must be placed on the tank fitting
and held in place to prevent this fitting from being overstressed.
The other wrench can be used to tighten the matching half of the
fitting onto it. Failure to follow this procedure will damage the
POLAR™ HD Heating Module and the fittings.
Do not operate the POLAR™ HD Heating Module until a proper
water/anti-freeze solution has been added to the POLAR™ HD
Heating Module and the heating system and all trapped air has been
bled. An inadequate mixture may cause system circulation problems
and potential POLAR™ HD Heating Module damage and/or personal
injury. Use an appropriate glycol based coolant.
