Section 7, Plumbing the System

Ensure a four (4) quart minimum overflow bottle is attached to the filler neck.

•The return and supply coolant plumbing connections are on the top of the Oasis™ Heating Module and are 1/2” male NPT fittings. The return coolant input to the Oasis™ Heating Module is a connection labeled “Inlet” and the supply coolant output from the Oasis™ Heating Module is a connection labeled “Outlet”. Ensure proper direction of flow. Refer to Figure 7-1: Heating Module for the location of the fittings.

•Two 1/2” NPT pipe to 3/4” hose barb fittings (not supplied) must be fitted into the Oasis™ Heating Module connections and tightened to a leak free condition using an appropriate thread sealant.

•Hose and/or tubing used to connect to the Oasis™ Heating Module or Distribution Module input and output connections must be heavy duty heater hose, minimum 3/4” I.D, or 5/8” PEX.

All fittings on the Oasis™ Heating Module require two wrenches when tightening. One wrench must be placed on the tank fitting and held in place to prevent this fitting from being overstressed. The other wrench can be used to tighten the matching half of the fitting onto it. Failure to follow this procedure will damage the Oasis™ Heating Module and the fittings.

Do not operate the Oasis™ Heating Module until a 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.
