5)
Allow your pool or spa filter pump to run continuously until the desired temperature is reached.
(This may take several days.) This may require resetting (or removing completely) the trippers on
the time clock to allow it to run continuously.
6)
To set the thermostat, allow the heat pump to heat the water until it reaches the temperature you
desire. Then, turn the thermostat knob slowly counterclockwise until the unit shuts off. The
heater will maintain your pool or spa at this temperature automatically.
Maintenance
All Aqua Cal heat pumps are designed for outdoor use but some maintenance is required to maintain
your warranty. In coastal areas where salt laden air or salt water spray can come in contact with the heat
pump, or where blowing sand can accumulate inside a heat pump, regularly scheduled planned
maintenance by an Aqua Cal technician or other certified representative is required. If your heat pump is
situated where falling leaves can accumulate on the inside of the machine, annual maintenance is
recommended to maintain your warranty. If you choose not to have the planned maintenance done,
rinsing the coil down monthly and keeping the base of the unit clear of leaves and debris is a must.
It is recommended that annual planned maintenance be performed on your heat pump by a licensed air
conditioning or pool heating specialist. You can schedule this through Aqua Cal at 800-786-7751.
CAUTION: IF YOU DECIDE TO WASH THE UNIT WITH A HOSE, DISCONNECT ALL POWER TO
THE EQUIPMENT PAD, INCLUDING THE POOL OR SPA EQUIPMENT TO PREVENT
POSSIBLE ELECTRIC SHOCK. DO NOT USE A PRESSURE CLEANER. IT MAY CAUSE
DAMAGE TO THE EVAPORATOR COILS.
Condensate Drainage
Condensation is a very normal function of your heat pump. When warm, moisture laden air passes over
the cooler evaporator coil (finned air coil), the air temperature is lowered and moisture is condensed
from the air. A typical heat pump can produce 6 to 8 gallons of condensate per hour.
If you are not sure whether the water draining from your heat pump is condensation or a water leak, you
can easily test for the presence of a sanitizer with your pool test kit. If you detect chlorine or bromine in
the water draining from your heat pump, it is not condensation. In this case, call Aqua Cal for service. If
no chlorine or bromine is detected, the water draining from your heat pump is condensate. If a water
sample cannot be obtained from the heat pump, there is another quick test you can perform. Simply turn
the heat pump off, still allowing the pool or spa pump to circulate water through the heater. With the
heater off and the pump continuing to circulate, allow the heater to remain off for a few hours. If the
water draining from the heater has slowed considerably, this would indicate that the water present was
from normal condensation. If the water has not slowed, this would indicate a leak.
It is important to keep the drain holes located around the bottom of the unit clean and free of debris that
might accumulate. Keep plants from growing near or next to your heater. Shrubs, especially, block air
from entering the machine and reduce the efficiency of the heater. Eventually, this can cause damage to
the unit if left uncorrected. Keep all shrubs at least 2 feet away from the outer air coil of the heater.
Surroundings
Have your pool or landscape technician remove any sprinkler heads that spray water onto the heater.
While heat pumps are made for an outdoor environment, they are not designed to have sprinkler water
constantly spraying them. Water used to irrigate can contain iron and other minerals that can coat the
heat collectors, causing poor heat transfer or eventually damaging the air coils and other internal
components. Premature rusting of components is a frequent symptom of the sprinkler system striking
the unit.
Pool Blankets
A pool blanket will significantly reduce your heating bills. You should check with the installing dealer to
see if your heat pump was sized to be used in conjunction with a solar blanket or without one. Blanketed
