Installation
Procedures
Unit Inspection
Inspect your unit very carefully before
installing. Make sure there has been no
damage to the evaporator fins or there
are no punctures or oil-soaked areas on
the box. This would indicate damage to
the refrigeration system and should be
rejected immediately.
THE UNIT MUST BE TRANSPORTED IN
THE UPRIGHT POSITION AT ALL
TIMES AND MUST NOT BE DROPPED
OR TAILGATED. DAMAGE TO THE
UNIT DURING TRANSPORTATION IS
NOT THE RESPONSIBILITY OF THE
MANUFACTURER.
Unit Location
Once the unit has been inspected and
cleared of any transportation damage,
it is now time to locate the pool
heater. It is very important to
understand the location of the unit for
the best performance of operation.
See Figure 1 for location
recommendations.
A minimum of 18” of clearance
between the evaporator coils and
shrubs, fences, walls, etc. must be
maintained for adequate air intake.
A minimum of 5’ of vertical clearance
between the top of the unit and any
roof overhang or other obstructions
must be maintained in order to
prevent the re-circulation of cold air
back into the evaporator coils. This is
to maintain the efficiency of the unit.
A minimum of 36” of clearance
between the front of the unit (access
panel area) and any obstruction must
be maintained to allow maintenance
on the unit when necessary.
The unit should be located on a solid
level surface, a minimum of 36”x 36”
for proper drainage.
Make sure any sprinkler heads are not
directly spraying water on the unit.
While heat pumps are made for an
outdoor environment, they are not
designed to have sprinkler water
constantly spraying them.
NOTE: This
type of constant watering directly
on the unit can void your warranty.
Condensation drain holes are provided
3
in all units for adequate removal of
condensation and rainwater.
ALL
UNITS WILL HAVE CONDENSATION.
THIS SHOULD NOT BE MISTAKEN
FOR A LEAK IN THE UNIT.
Plumbing
Where freezing weather is encountered,
the detachable connection/union
(provided on PRO1000) must be installed
immediately adjacent to the heater to
facilitate servicing and draining of the
heat exchanger.
Draining is necessary
to prevent damage to the condenser
shell and coil due to the expansion
of freezing water.
The minimum water circulation
capacity flowing through the pool
heater is 25 gallons per minute and the
maximum capacity is 80 gallons per
minute.
Do not install a water shutoff valve in
the piping from the outlet of the pool
heater to the pool or spa. However, a
check valve that does not include a
shut-off feature may be installed for
convenience during servicing.
A check valve or Hartford Loop is
recommended between the unit and a
chlorinator. The chlorinator must be
downstream of the heat pump. Failure
to do so may void the warranty.
If you have an in-floor cleaning system,
please take note of any special
plumbing requirements to operate all
units effectively.
Figure 2 shows the recommended
installation layout.
