7.6 Engine Plumbing Installation
The Engine Heat Supply/Return connections are located on the top
(towards the back) of Oasis
®
Chinook. These connection points are
1/2" hose. The connection can be made by placing PEX inserts into
the 1/2" PEX hose, and sliding 1/2" PEX into the hose and clamping
it in place. Alternatively, a 1/2" barb to 1/2" or 3/4" barb fitting can
be used to make the connection to the engine coolant hose.
Hot coolant from the engine enters the Oasis
®
Chinook at the
“Engine Supply”. The “Engine Return” returns the coolant back to
the engine. This makes use of engine waste heat.
If the pre-heat function is installed, an additional pump is installed
(outside the Oasis
®
Chinook) to move the engine coolant through
the engine heat exchanger, when the engine is turned OFF. The pre-
heat switch on the Remote Operating Panel will activate this pump.
See Figure 7-5: Engine heat/pre-heat system plumbing.
It is recommended to contact the vehicle/engine manufacturer prior
to proceeding with the engine plumbing installation.
