Isolation Valve (Service Valve Kit)
: The manufacturer stocks the Isolation Valve(Service Valve Kit) for easy water line installation. The
Isolation Valve (Service Valve Kit) is necessary for flushing the Heat Exchanger. This valve kit includes an integrated shut-off and
service valve with unions and a pressure relief valve.
(*2)
Air Vent and Air Out
: In order to prevent air locking in the recirculation pump, air out and air vent shall be installed near the Water
Heater on the return line.
(*3)
Valve
: For maintenance of expansion tank.
(*4)
Expansion Tank
: Confirm manufacture’s specification (e.g. Maximum temperature resistance at least 200°F (93°C), Tank volume,
Maximum pressure) for the expansion tank. Without this expansion tank, the increased volume of water created by thermal
expansion may be relieved from a pressure relief valve. In order to prevent this, the expansion tank shall be installed on the return
line. The charged pressure (PSI) of expansion tank shall be set to cold water supply pressure for correct operation.
(*5)
Pressure Relief Valve
: The increased volume of water created by thermal expansion may be relieved from the Pressure Relief Valve
in order to prevent damage to the system. It is normal operation for system safety.
(*6) An On Demand Switch must be connected
to the Master Water Heater which the
Remote Controller is connected for Quick
Connect Multi System.

• (Only when conforming to California Code of Regulations Title 24 Part 6)
- Change the Recirculation setting. (See page 59)
- Install On-demand Switch and Thermo-sensor. (See page 50)
NOTE
If gurgling noise occurs or the error code 63 appears on the Remote Controller, it may be caused
by air remaining in the system (e.g. Cold Water Line, Hot Water Line, Return Line or Water
Heater). Purge air from the system completely, following instructions on page 60-64.
