Raypak 5350 Series, Installation & Operating Instructions Manual

Page: 6 / 28

Introduction
This manual contains important information on the
use, maintenance and troubleshooting of your new
heat pump pool heater. This unit must be properly
installed, maintained and operated for optimal per-
formance.
This heat pump pool heater is an extremely efficient,
economical machine designed specifically for swim-
ming pool heating. It is similar in design and operation
to a typical residential air conditioning system. The unit
employs a hermetic motor/compressor operating in a
refrigeration cycle to extract heat from ambient air and
deliver it to the circulating pool water.
As with all heat pump pool heaters, compared to other
types of heaters such as gas or oil-fired, this heat
pump pool heater has lower heating capacity on a
BTUH/hr basis. As a result, it will be required to oper-
ate longer to accomplish the desired results. It may, at
certain times, operate as much as 24 hours per day.
However, this should not be of concern to the owner,
because the unit is designed to operate continuously.
Even though it may operate continuously for many
hours, it will still heat the pool with greater economy
than other types of fossil fuel heaters.
Place a cover or blanket over the pool at night and
other non-use periods. This will keep evaporation, the
cause of main heat loss, to a minimum, and will great-
ly reduce pool heating costs. During warmer weather,
the cover may be required only at night.
Installation Considerations
Situate the heat pump pool heater carefully to mini-
mize installation costs while providing maximum
efficiency of operation, and to allow adequate service
access, as follows:
• For unrestricted air intake and service access,
position each side of the unit at least 1 ft (30 cm)
from walls, pipes and other obstructions.
• Recirculation of cold discharge air back into the
evaporator coil will greatly reduce the unit’s heat-
ing capacity and efficiency.
• This unit features an ‘up-flow’ discharge for quiet
operation. Air is pulled up through the evaporator
coil and discharged through the top grill. Allow at
least 5 ft (1.5 m) clearance above the unit for unre-
stricted air discharge. DO NOT install the unit
under a porch or deck. Refer to Fig. 1.
• To minimize water piping, locate the unit as close
as possible to the existing pool pump and filter.
• If the location of the heat pump pool heater is
below the water line of the pool, the water pres-
sure switch might need to be adjusted or an
external water flow switch might be needed.
WARNING: This pool/spa heat pump pool heater is
an electromechanical machine that incorporates a
pressurized refrigerant gas in a sealed system.
ONLY trained and qualified service personnel are
authorized to install or service this equipment.
Without proper training and knowledge of such
equipment, any attempt to install or service the unit
could result in serious injury or even death.
WARNING: Do not install the unit within 3 ft of
fossil fuel burning heaters. Air intake along the
sides of this heat pump pool heater could disturb
the combustion process of the unit, and could
cause damage or personal injury.
• Mount the unit on a level, sturdy base, preferably a
concrete slab or blocks. The size of the base should
be at least 3 ft by 3 ft.
• You must install the 4 black rubber sound iso-
lation pads (each 2 inches square) that ship with
the unit. The pads are shipped in a bag with the
unions, gaskets and the I&O manual. Install pads
under the 4 corners of the unit to reduce vibra-
tion and sound transmission to the base.
CAUTION: The unit’s supporting base must be high
enough to keep it completely free of standing water
at all times.
WARNING: This unit is designed for outdoor instal-
lation; DO NOT install it in an enclosed area such as
a shed or garage.
