Section 9, Installing the Distribution Module

WARNING

The Domestic water connections are located on top of the module. The Cold water supply can be connected using a ½” NPT fitting. The maximum water supply pressure to the module is 150 PSI (10 bar). The Hot water Outlet temperature is regulated by an internal mixing valve factory set at 120F (49°C). If needed this valve can be adjusted in a range from 100F (38°C) to a maximum of 145F (63°C). For more details about adjusting the temperature see chapter 9.9. A domestic water drain is provided for winterizing purposes. This will prevent damage to the internal heat exchanger due to freezing water. See Figure 9-4: Domestic Hot water system plumbing.

All fittings, hose, tube and fitting sealant involving the domestic water must be food safe and approved for use with domestic

water and rated for the domestic water system pressure.

The engine heat/pre-heat connections are located on the side of the distribution module. Hot coolant from the engine enters the module at the “engine heat inlet”. The “engine heat outlet” returns the coolant back to the engine supply. When the pre-heat function is installed an additional pump is connected between the “engine heat outlet” and the engine
