3 If the Distribution Module is not utilized, connect the cabin
fan heater supply lines to the supply coolant “Outlet” from the
Oasis™ Heating Module. Ensure there are no kinks or sharp
bends that might restrict the fluid flow. See Figure 7-2: Three
Approved Methods of Installing Heater Hose (Consult ITR for
Alternative Methods and Products) for methods of attaching the
heater hose.
Connect the cabin fan heater return lines to the return coolant
“Inlet” on the Oasis™ Heating Module. Ensure there are no
kinks or sharp bends that might restrict the fluid flow.
4 Fill the Oasis™ Heating Module through the filler neck with the
recommended propylene glycol/water anti-freeze solution and
bleed all trapped air.
Do not operate the Oasis™ Heating Module until the proper
water/anti-freeze solution has been added to the Oasis™
Heating Module and the heating system and all trapped air has
been bled. An inadequate mixture may cause system
circulation problems and potential Oasis™ Heating Module
damage and/or personal injury.
Use only a non-toxic, propylene glycol based coolant with
additives recognized as safe “GRAS” by the FDA. Refer to the
anti-freeze manufacturer recommendations for instructions for
your application.
