“Almost” Everything You Need To Know…
To Get It Running … and Keep It Running
FILTER PUMP OPERATION
Note: Some systems utilize a timer to control filter pump run
time. If your system incorporates a timer, follow the instructions
below:
The filter pump will need to run continuously until the water
has reached the desired temperature. If a timer controls your
filter pump, it will be necessary to override the timer to allow
for temporary, continuous operation.
Once the desired temperature has been obtained (usually
1-to-4 days), reset the pump timer for normal operation.
NOTE: The heater can only operate when the filter pump is
running. It may be necessary, during cooler weather, to extend
the pump’s daily hours of operation. This will enable the heater
to keep up with increased heat losses.
NORMAL USAGE
After the heat pump has been running for some time, water
may be seen around the unit. This is condensation produced
as a normal by-product of transferring heat from the air to
the pool or spa. Quantities of 6-8 gallons per hour are not
uncommon when the humidity is high. Conversely, a low
ambient humidity condition may result in no condensation.
VERY IMPORTANT NOTE!! Water chemistry …Your heat
pump has been engineered for durability and reliability;
however, prolonged exposure to unbalanced water chemistry
will result in premature failure and service requirements.
Keep chlorine in the 1-3 PPM range- If bromine is being used,
2.0 to 4.0 PPM.; pH between 7.4 and 7.6; Alkalinity, 80-100
PPM; hardness 125 PPM (or more). Exact needs will depend
on the type of pool surface; check with your pool service expert.
See owners manual for more detailed information.
TO STOP THE HEATER
Select: OFF via the MODE selector. This method of shut
down preserves the controller settings; an interruption of
water flow–such as when a pump timer is in control–will
also cease heat pump operation.
MAINTENANCE & WINTERIZING
Your heat pump should be cleaned and inspected on an annual
basis by a qualified pool heat pump specialist. If your heat
pump is located on the beach or a sea wall, where salt spray
and sand gets in or on the unit, more frequent maintenance
will be necessary. Contact AquaCal for details.
Provide proper airflow to the heat pump. Keep the sides and
top of the heat pump free of obstructions.
Control Irrigation: where wells are used for irrigation, water
quality can be poor. Heat pump components can be damaged
by well water; regardless of water quality, it is recommended
sprinklers be directed away from the heat pump.
Drainage... as previously stated, your heat pump, under various
conditions, will produce large quantities of condensation. Keep
the drain holes, located at the base of the heat pump, free of
grass and weeds.
If your heater is located under trees, leaves may fall and
accumulate in the bottom of the heat pump. Accumulated
debris should be removed by a qualified technician.
VERY IMPORTANT NOTE!! In areas where hard freeze
conditions occur, proper winterizing of the heat pump is
critical. For detailed instructions on winterizing, refer to
“Winterizing” in the heater manual, or at www.aquacal.com.
In areas where light freezing conditions occur–lasting less
than four (4) hours–keep the water pump operating. Flowing
water will not freeze under limited, light freeze conditions.
1. Verify Electrical Power is Present at Heater:
A. Ensure the heater has electrical power connected; the
controller display should be illuminated.
B. If the display is blank, be certain the electrical breaker, and
heater disconnect, are switched to “ON.”
C. For now, leave the water circulation pump OFF.
3. To Begin Heating:
A. Verify MODE is set to: HEAT (HEA); then, depending on
the body of water to be heated, use the POOL / SPA selector
key to choose either POOL or SPA.
B. Position external water valves appropriately to flow water
to-and-from the body of water and through the heater.
C. Start the water pump...Within 4-minutes, depending on
the status of the controller’s internal time delay, the
heater will start. The water will be brought to temperature
and maintained per the setting determined previously
in: “Set the Heater Controls.”
D. In operation, whenever the actual (displayed) water
temperature falls below the desired set point, the unit
will begin heating.
– GETTING ST
ARTED –
These instructions are intended for local control of a heat pump,
independent of an external controller. Owners: if your installation
includes an external controller, contact your installing dealer for
operational instructions.
These instructions are for quick-starting in heating mode
only...owners of Heat-Cool units, in order to utilize all features of
their heater, will certainly want to also refer to: “Owner Level Pro-
gramming,” located within the full heater manual.
D. If heating a pool, use the UP / DOWN arrow keys to set
the desired water temperature for the POOL water.
E. If the heat pump will be used to heat a spa, use the POOL/
SPA selector key to select SPA, then use the UP / DOWN
arrow keys to set the desired water temperature for the
SPA. If heating only a POOL, using the DOWN arrow key,
lower the SPA temperature until OFF is displayed.
F. The heat pump controls are now set to maintain the desired
water temperature for the POOL and/or SPA.
2. Set the Heater Controls:
OWNER- If heater is connected to a Call-Flex controller, also
see: “Call-Flex Programming,” located within the “Owner Level
Programming” section of the heater manual.
INSTALLER- Is heater connected to an external controller? If so,
set up programming is necessary. See: “Controls Configuration,”
located within the “Level-2 Programming” section of the heater
manual.
A. The user/owner settings can be completed without water
flowing. Once the heater has electrical power connected,
with water not flowing, the display should read FLO.
B. Press the MODE button until the HEAT (HEA) indication
displays.
C. Using the POOL / SPA selector key, select the POOL
mode. An illuminated POOL indicator light, located on
the left side of the display, will confirm the POOL control
has been selected. If heating only a spa, using the DOWN
arrow key, lower the POOL temperature until OFF is
displayed; then proceed to Step-“E.”
