WARNING

1. To allow for proper condensation drainage,

use a level slab to elevate the heat pump to

at least the same height as the pool ﬁlter

system slab, or 2 to 3 inches minimum

above grade.

2. Allow the minimum air ﬂow clearances on

top and the sides as shown here. Make sure

the unit can “breathe” well. Do not install

indoors or where the discharge air can ac-

cumulate and be drawn back through the

heater. Make sure the front is accessible

for future service.

3. Keep sprinkler heads at least 6 feet away

from the heat pump. Do not allow the

sprinkler to spray the unit in any way to

prevent damage.

4. If the unit is installed under a roof overhang

or under a roof valley, a gutter or diverter

should be ﬁtted to prevent excessive water

from pouring into the unit.

5. Keep all plants and shrubs trimmed away

from the heater to the minimum clearances

shown here to prevent air coil damage.

6. If the heater is installed above or below

the pool water level by more than 3 feet

you may require an external water ﬂow

switch. See the top of section C8 for more

information.

3. BYPASS FOR FLOW RATES OVER 70 G.P.M. Typi-

cally the automatic internal water bypass can handle up to a

1.5 H.P. water pump or 70 G.P.M. If the water pump exceeds

1.5 H.P. then install either of the optional bypasses as shown

below. The installation of a ﬂow meter on the WATER OUT

line is suggested. Adjust the bypass to divert a minimum of

40 to 50 G.P. M. through the heater. Flow meters should be

installed per the manufacturer’s instructions.

1. BASIC PLUMBING. For a pool only

or spa only, install the plumbing piping

as shown. Connections from factory

are 2”unions. Hand tighten then 1/4 to

1/2 snug tight with pliers. Water IN on

the RIGHT, Water OUT on the LEFT.

FEEDERS

C. PLUMBING & WATER CONNECTIONS

4. MULTI UNIT WATER CONNECTIONS

Plumb multiple units as shown below. Use ﬂow meters on each

WATER OUT line if two or more units are plumbed together.

Use ball valves to balance the water ﬂow through each unit.

Using T’s, caps and a minimum 6 inch pipe extension on the

plumbing manifold will help equalize the water ﬂow better than

90˚’s. Flow meters should be installed per the manufacturer’s

instructions.

5. POOL/SPA COMBINATIONS W/SPILL-OVER

Use this diagram for

a connected pool and

spa, where the spa has

a spill-over type wa-

terfall into the pool.

Where one pump and

one heater are used for

both the pool and spa.

If the water pump ex-

ceeds 1.5 H.P. then in-

stall a external bypass

as shown on page 5.

7. PLUMBING WITH SOLAR.

Plumbing for a system where a solar pool

heater is installed. It

is strongly advised

that an automatic so-

lar control device be

used when used with

the heat pump. If the

water pump exceeds

1.5 H.P. then install

either of the optional

bypasses as shown on

page 5.

The heat pump and solar can be operated

together. The heat pump will share the heating

load with the solar. If the solar is operated on cloudy

days, while raining, at night or at low air temperatures,

it may cool the pool or spa. An automatic solar control

will shut the solar off when there is no solar heat gain,

otherwise it should be shut off manually during these times.

To use the heat pump as a backup to the solar, set the heat pump thermostat 2 to 4 degrees below

the solar’s target temperature setting. Therefore, if the solar is not maintaining water temperature,

the heat pump will come on to assist the solar. Some thermostat ﬁne tuning may be required by the

user.

C. PLUMBING & WATER CONNECTIONS

8. PLUMBING & WATER CONNECTIONS FOR ABOVE OR BELOW WATER LEVEL

If you install the heat pump above or below the pool or spa water level by more than 3 feet, the internal

water pressure switch may be effected by the static pressure of the pool water. In some cases it

may be necessary to eliminate the internal water “PRESSURE” switch and install a water “FLOW”

switch. The water ﬂow switch is not effected by changes in water pressure but only water movement.

We suggest installing a 2”, Grid Brand Model 20 ﬂow switch and disabling the internal water pressure

switch. Plumb in the ﬂow switch as shown here. Then run a TWO wire insulated cable from the ﬂow

switch into the heater and attach to the existing water pressure switch leads located on the heater’s

logic board, behind the low voltage service panel and wire as shown below.

D. WINTERIZING PROCEDURES

1. LIGHT-FREEZE CONDITIONS

(Air temperature does not remain below 32ºf for more than 4-hours)

In the event your heater will not be used for an extended period, it is recommended pool water

be allowed to circulate through the heater during normally scheduled ﬁltration cycles. If light

freeze conditions are expected, adjust water pump controls for continuous operation throughout

the light freeze episode. Moving water will not freeze under light-freeze conditions. Remain

aware of abnormal climatic conditions; use “hard-freeze” instructions

(Below) if freezing conditions will exceed 4-hours.

CAUTION !

FAILURE TO PROPERLY WINTERIZE HEAT PUMP MAY RESULT IN SERIOUS

EQUIPMENT DAMAGE. FREEZE DAMAGE IS NOT COVERED UNDER THE

HEAT PUMP WARRANTY. FAILURE TO HEED THE FOLLOWING CAN RESULT IN

DAMAGE TO EQUIPMENT AND/OR PROPERTY.

E. ELECTRICAL CONNECTIONS AND WIRING

MAKE SURE TO TURN OFF ALL POWER TO UNIT INCLUDING POWER

TO POOL PUMP TIMER PRIOR TO MAKING ANY ELECTRICAL CON-

NECTIONS. SPECIFICATIONS ARE SUBJECT TO CHANGE. ALWAYS

REFER TO WIRING DIAGRAM LOCATED ON THE BACK OF THE UNIT’S

PLASTIC FRONT COVER AND DATA PLATE ON LEFT SIDE OF PLASTIC

FRONT PANEL.

1. SUPPLY WIRING 220V

• Remove plastic front panel from unit.

• Locate and remove electric box high voltage cover located on left side of electric box.

• Determine sealtight length and slip plastic adaptor over conduit. Run conduit and proper

2. HARD-FREEZE CONDITIONS

(Air temperature remains below 32ºf for more than 4-hours)

WARNING !

TO AVOID INJURY FROM ROTATING EQUIPMENT, DISCONNECT ELECTRICAL

POWER FROM HEAT PUMP BEFORE PROCEEDING WITH INTERNAL DRAIN

WINTERIZING PROCESS. FAILURE TO HEED THE FOLLOWING MAY RESULT

IN PERMANENT INJURY OR DEATH.

1. Disconnect all electrical power to the heater; turn off circulating pump.

2. At the two (2) connection unions, disconnect the plumbing to the heater (removal is

counterclockwise).

3. Locate the drain plug at outside, lower front of heater. (see ﬁgure 1)

If the unit does not have an external drain plug, remove the exterior front panel of the unit.The

internal drain plug is located at the base of the heat exchanger (see ﬁgure 2). Follow the same

procedure as with an external drain plug.

4. Using a 5/8”, box-end wrench, remove the drain plug (removal is Counterclockwise).

5. Permit all water to drain from the condenser and then replace the plug: thread the plug in

clockwise until just snug, then apply an additional 1/8 turn.

6. To prevent insects and vermin from entering the plumbing during the winterized period,

partially reconnect the two (2) plumbing connection unions: couple each union one or two

threads; this will permit condensation to drain, but will prevent most insects and animals from

entering the plumbing circuit.

7. Next season: to ready the heat pump for use, simply retighten plumbing connection unions.

Hand-tight is generally sufﬁcient.

size wire from power supply to the unit’s main contactor located on the right side of high

voltage compartment. The ground wire connection is located on the base of the box to the

left of the contactor. A knock out is located on the bottom of the box just below the contactor.

A sealtight ﬁtting must be used to attach the conduit to the electric box. All other models

require minimum #8 copper stranded wire. Model AT 1200 requires #6 wire.

• Replace electric box high voltage cover.

• Replace plastic front panel and place conduit and plastic adaptor in slot provided on right

To interface the “Digital Logic” digital control heat pump models with the Jandy AquaLink RS series

or Compool, run a 2 wire (16 A.W.G. or larger) insulated cable from the device to the heat pump.

Remove the 6 screws from the heaters front service access panel and open. Look for the heater’s

solid state circuit board located inside the top portion of the electrical compartment mounted on the

rear wall. Locate, remove and discard the ”METAL JUMPER TAB” attached to the bottom terminal

bar and labeled “Jandy/Compool”. Then, run a 2 wire cable from the 2 position terminal where the

metal jumper tab was, through the heater’s low voltage access port, then to the AquaLink RS or the

Compool control.

NOTE for AquaLink RS and Compool: Turn both heater thermostats all the way up and set the

mode selector switch to pool and do not use the heater controls as the Jandy or Compool now has

thermostatic control over the heater.
