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.
