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 fo
r
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.
