2. CONNECTING THE WATER SUPPLY
2.1. TYPICAL INSTALLATION
WATER SUPPLY CONNECTIONS
Refer to the illustration above for suggested typical installation. The installation of unions or flexible
connectors is recommended on the hot and cold water connections so that the water heater may be easily
disconnected. To tighten the water connectors, please use a back-up wrench. For ease of maintenance, we
strongly recommend to install service valves in inlet and outlet water circuits (see Flushing the water heater
section page 41). Over-tightening or tightening without a back-up wrench may cause flow sensor damage.
Take special care.
TIP: Water connections are located further to the front of the unit than many other storage water
heaters. Plan accordingly. For example, longer water flexes may be required.
FILTER
Before connecting the cold water supply to the unit, check that the filter is still well installed in the cold inlet
brass fitting. If sediment in the local water supply is an issue, we recommend installing an external Y strainer.
