Section 7, Plumbing the System

•Use heavy-duty heater hose or PEX tubing. Slip-on foam insulation coverings may be used over the hose fittings to reduce heat loss. Secure all hose connections with spring clamps.

•Air vents for the fluid circulation system are not supplied, but may be optionally installed to help bleed air from the system.

7.3What NOT to Do

NOTICE

The Oasis™ Heating Module’s circulating water pump is one of the most critical parts of the system. Never let the pump run dry or you will damage the impeller. This is not covered under warranty.

Don’t use low-quality heater hose.

Don’t let the hose come into contact with solvents, which may cause it to soften and swell. If there is any risk that solvents may contact the hose, insert it into PVC plastic tubing for protection.

7.4Installation Procedure

To install and connect the Oasis™ Heating Module and heater hose:

1The supply and return coolant connections are on top of the Oasis™ Heating Module and are 1/2” male NPT fittings. The return coolant input to the Oasis™ Heating Module is labeled “Inlet” and the supply coolant output from the Oasis™ Heating Module is labeled “Outlet”. Ensure proper direction of flow.

2Two male 1/2” NPT x 3/4” hose barbs (not supplied) must be fitted into the supply and return fittings and tightened to a leak free condition.

If the Distribution Module is to be used with the Oasis™ Heating Module, refer to Section 9, Installing the Distribution Module.
