Section 9, Installing the Distribution Module
International Thermal Research 9-7
Figure 9-7: Connecting two Heating loops.
Do not operate the POLAR™HD Heating Module and Distribution
Module, DM12 (Optional) until coolant is in the POLAR™ HD
Heating Module and Distribution Module and all trapped air has
been bled.
All plumbing lines must be run and secured so as to prevent
damage, chafing and kinking.
9.5 Filling/Purging the heating system
The Distribution module contains two valves with ½”NPT
connections to be used for filling the heating loop. To initially fill
up and bleed the air out of the system, do the following:
1. Connect a hose to the outlet of a diaphragm pump and to the
“fill inlet valve” on the distribution module. Attach a hose to the
inlet of a diaphragm pump and place the hose in a container
filled with a 50/50 mixture of propylene glycol and water (see
Figure 9-8).
2. Connect a hose to the “fill outlet valve” on the distribution
module and place the other end of the hose in the same
container.
