Safety Warning
The purpose of this Service Manual is to provide sufficient information to allow a person
with the skills as required by the controlling Regulatory Authorities to carry out effective
repairs to a Raypak pool and spa heat pump in the minimum of time.
Safety precautions or areas where extra care should be observed when conducting tests
outlined in this manual are indicated by print in bold italics and/or a warning symbol. Take
care to observe the recommended procedure.
Certain diagnostic procedures outlined in these service instructions
require “live” testing to be conducted. Personal Protective Equipment
(PPE) should be worn when conducting these tests to prevent the risk of
electric shock (Refer to Rheem Safety Procedure on electrical testing).
R22 is a controlled substance under the fair trading act. Personnel
qualified and licensed to work with refrigerants may only carry out service
and repair to the sealed refrigeration system. During repair the refrigerant
must be recovered, not vented to atmosphere.
Environmental
At the end of the service life of a Raypak heat pump the R22 refrigerant
must be recovered by personnel qualified and licensed to work with
refrigerants prior to the unit being disposed of. R22 must not be vented to
atmosphere.
Introduction
The information provided in these instructions is based on the pool/spa heater being
installed in accordance with the Installation Instructions provided with each pool/spa
heater.
Should you require further technical advice on a Raypak Heat Pump, contact your nearest
Rheem Service Department where all genuine replacement parts are also available.
General Description
The cabinet is manufactured from polyester coated Dura Steel™ whilst the heat exchanger
is of alloy construction. The unit comes with two temperature dials to allow separate pool
and spa temperature settings selectable by a Spa-Remote-Pool selector switch.
Raypak Heat Pump is suitable for external locations only and must not be installed in a
totally enclosed area such as a shed or garage unless ventilation is provided to ensure
adequate air exchange for proper operation. Recirculation of cold discharge air back into
the evaporator coil will greatly reduce the units heating capacity and efficiency.
Preventative Maintenance
It is suggested for peak performance that the pool/spa heater be serviced annually.
1. Check for leaks at all water connections and fittings.
2. Check for signs of excessive corrosion on the jacket.
3. Isolate power to the pool/spa heater and check all electrical connections for signs of
overheating due to poor connection.
4. Conduct an insulation test on the pool/spa heater (Refer to page 31).
5. Check evaporator fins and fan blade for build up of dust or debris.
6. Check condensate drainage holes in base of unit are not blocked with dirt or debris.
