Section 9, Installing the Distribution Module

• 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.

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
