Leisure Temp LT400 Quick Start

"Almost" Everything You Need To Know...
To Get It Running ... and Keep It Running
These instructions are intended for local control of a
heat pump, independent of an external controller.
OWNERS: if your installation includes an external controller, con-
tact your installing dealer, and/or the controller manufacturer, for
operational instructions.

1. Verify Electrical Power is Present at Heater:

A. Make certain 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.

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,
setup 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 flow-
ing. 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 dis-
plays.
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 select-
ed. If heating only a spa, using the DOWN arrow key, lower
the POOL temperature until OFF is displayed; then proceed
to Step-"E."
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.
E. (Setting SPA, continued) An illuminated SPA indicator light,
located on the left side of the display, will confirm the SPA
control has been selected. 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.

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; the fan will start...Within 4-minutes,
depending on the status of the controller's internal time de-
lay, heating will begin. The water will be brought to tempera-
ture and maintained per the setting determined previously in:
"Set the Heater Controls."
D. In operation, whenever the actual (displayed) water tempera-
ture falls below the desired set point, the unit will begin heat-
ing.

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 stop heat
pump operation.

FILTER PUMP OPERATION

NOTE: Some systems utilize a timer to control filter pump run
time. If a timer is present, follow instructions below:
The filter pump will need to run continuously until the water
has reached desired temperature. If a timer controls your fil-
ter pump, it will be necessary to override the timer to allow for
temporary, continuous operation.
Once the desired water temperature has been obtained (usu-
ally1-to-4 days), reset the pump timer for normal operation.
NOTE: The heater can only operate with the filter pump running.
It may be necessary, during cooler weather, to extend the pump's
daily run time. This will enable the heater to keep up with in-
creased 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. Water from heater seems excessive? See
"Water Coming From Heat Pump" later in this guide.
VERY IMPORTANT NOTE!! Water chemistry ...Your heat pump
has been engineered for durability and reliability; however, pro-
longed 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 additional information.
MAINTENANCE & WINTERIZING
Your heat pump should be serviced annually 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 Customer
Support for details (727-823-5642).
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 qual-
ity can be poor. Heat pump components can be damaged by
well water; regardless of water quality, it is recommended sprin-
klers 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 accu-
mulate in the bottom of the heat pump. Accumulated debris should
be removed by a qualified technician.
VERY IMPORTANT NOTE!! In areas where hard freeze condi-
tions 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.
