Service Technician"S Heat Pump Kit - Rheem 325 II Series Service Instructions Manual

SERVICE TECHNICIAN'S HEAT PUMP KIT
A Service Technician‟s Heat Pump Kit is available and may be required for work carried
out on a 325 or 410 Series II Heat Pump.
The Service Technician‟s Heat Pump Kit must be ordered through Rheem Spare Parts,
Rheem part number 299265.
The kit provides aids for conducting work and diagnosing problems with 270, 325 and 410
Series Heat Pumps as well as 325 & 410 Series II Heat Pumps.
Primarily, the kit provides the ability to conduct a full functional test on the appliance, which
is required at the completion of any service work. The kit also facilitates the technician‟s
ability to diagnose problems with the appliance, in circumstances where the faults present
may otherwise hinder this process.
Heat Pump Service Power Cable
In situations where timed (off peak) power is
unavailable, the Heat Pump Service Power Cable
must be used to provide power to operate the unit in
order to diagnose a fault and / or conduct a full
functional test at the completion of any service work.
The Heat Pump Service Power Cable is plugged into
the heat pump module‟s controller, in place of the
normal mains power cable that relays power from
the storage tank – see the diagram on page 11.
Before using the Heat Pump Service Power Cable, isolate power to the water
heater. Remove the mains power cable from the bottom of the heat pump‟s
controller, and plug in the Heat Pump Service Power Cable instead.
The Heat Pump Service Power Cable has an integrated power switch, and is plugged into
a standard 240V AC 10A mains supply general power outlet. An extension cable will most
commonly be required to reach the closest GPO, and it is recommended that an earth
leakage circuit breaker device (not supplied) be utilised as well.
The heat pump module can now be operated. The Heat Pump Service Power Cable must
be removed and the normal mains power cable replaced at the completion of the work.
The Heat Pump Service Power Cable may need to be used in conjunction with the Proxy
Tank Sensor if the water in the storage tank is fully heated.
