WARNING

The following “Safety Rules for Hot Tubs,”
recommended by the U.S. Consumer Product
Safety Commission, should be observed when
using the spa.

AVERTISSEMENT

Les Règlements suivants pour Cuves
Thermales, tel que recommandés par la
Commission U.S. de Sécurité des Produits pour
les Consommateurs, devraient être respectés
lors de l’utilisation du spa.

AVISO

Al utilizar el spa, deberán observarse, las
siguientes “Reglas de Seguridad para Baños
Calientes” recomendadas por la Comisión de
Seguridad de Productos para el Consumidor de
los Estados Unidos.

Page 3

1. Spa or hot tub water temperature should never
exceed 104°F (40°C). One hundred degrees
Fahrenheit (100°F [38°C]) is considered safe for a
healthy adult. Special caution is recommended for
young children.

2. The drinking of alcoholic beverages before or
during spa or hot tub use can cause drowsiness
which could lead to unconsciousness, and
subsequently result in drowning.

3. Pregnant women take note! Soaking in water

above 102°F (38.5°C) can cause fetal damage
during the fi rst three months of pregnancy (which
could result in the birth of a brain-damaged or
deformed child). If pregnant women are going
to use a spa or hot tub, they should make sure
the water temperature is below 100°F (38°C)
maximum.

4. The water temperature should always be checked
with an accurate thermometer before entering a
spa or hot tub. Temperature controls may vary by
as much as 1F° (1C°).

5. Persons with a medical history of heart disease,
diabetes, circulatory or blood pressure problems
should consult their physician before using a hot
tub or spa.

6. Persons taking any medication which induces
drowsiness (e.g., tranquilizers, antihistamines, or
anticoagulants) should not use spas or hot tubs.

7. Prolonged immersion in hot water can induce
hyperthermia.

Hyperthermia occurs when the internal body

temperature reaches a level several degrees above the
normal body temperature of 98.6°F (37°C). Symptoms
include dizziness, fainting, drowsiness, lethargy, and an
increase in the internal body temperature. The effects of
hyperthermia include:

1.2.2 Swimming Pool Energy Saving Tips

It is important to note that a heat pump will not
heat a pool as fast as a large gas or electric pool heater.
If the pool water is allowed to cool significantly, it may
take several days to return to the desired swimming

temperature. For weekend use, it is more economical

to maintain the pool water temperature at or near your

desired swimming temperature. If you do not plan to

use your pool for a prolonged period, then you might

choose to turn the heat pump completely off or decrease

the temperature setting of the control several degrees to
minimize energy consumption.

Jandy offers the following recommendations to
help conserve energy and minimize the cost of operating
your heat pump without sacrificing comfort.

1. The American Red Cross recommends a maximum

water temperature of 78°F (25°C). Use an accurate

pool thermometer. A difference of 4°F (2°C) ,

between 78°F and 82°F (26°C and 28°C), will

signifi cantly increase energy consumption.

2. Carefully monitor the water temperature of your

pool in the summertime. You can reduce heat

pump usage due to warmer air temperatures.

3. During the winter or when on vacation for longer

than a week, turn off the heat pump.

4. Find the proper setting on the heat pump

temperature control and use the Keypad Lock

function or lock the smoke-colored cover on

the heat pump controller to discourage further

adjustments.

5. Set the pump time clock to start the pump no

earlier than 6:00 AM during the pool heating

season. This is the time when nightly heat loss

balances.

6. Where possible, shelter the pool from prevailing

winds with well-trimmed hedges or other

landscaping, cabanas, or fencing.

• Lack of awareness of impending hazard

• Failure to perceive heat

• Failure to recognize need to leave spa

• Physical inability to leave spa

• Fetal damage in pregnant women

• Unconsciousness resulting in a danger of
drowning

7. Always use a pool cover when practical. Besides
providing a valuable safety feature, a pool cover
will reduce heat loss, conserve chemicals, and
reduce the load on fi lter systems.

1.3 Warranty

The AE-Ti heat pump is sold with a limited factory

warranty. Details are specified on the back cover of this
manual.

Recommended Clearances for

Serviceability

NOTE Clearances listed in
Table 1 are manufacturer’s
tested values. These are
given as minimum values.
Where local and national
codes apply, and values are
different than those listed in
Table 1, use the greater value
to ensure safe and proper
operation.

Avoid placing the heat pump in locations where
it can cause damage by water or condensate leakage. If
this is not possible, provide a suitable drain pan to catch
and divert any leakage.

All criteria given in the following sections reflect
minimum clearances. However, each installation must
also be evaluated, taking into account the prevailing
local conditions such as proximity and height of walls,
and proximity to public access areas.

2.2.2 Clearances

The heat pump must be placed to provide
clearances on all sides for maintenance and inspection.
See Table 1.

24” (61cm) access in front of the heat pump
provides adequate room for serviceability.

If the heat pump is to be installed in a garage
or under a vertical overhang, the unit must have a
minimum of 5 feet clearance from the top of the heat
pump.

In the U.S., the heat pump must be installed at least
5 feet (1.52 meters) from the inside wall of the pool or
spa unless the heat pump is separated from the pool or spa
by a 5 foot high solid fence or other permanent barrier.

Aux Etats-Unis, ce chauffe-piscine doit être
installé á au moins 5 pieds (1.5 m) de la paroi interne
de la piscine à moins d’être isolé de la piscine par une
clôture, un mur ou autre barrière permanente.

En Estados Unidos, esta bomba de calor deberá
instalarse a una distancia de al menos 5 pies (1.5
metros) de la pared interior de la piscina; a menos que la
bomba de calentar esté separada de la piscina mediante
una valla sólida de 5 pies (1.5 metros) de altura u otra
barrera permanente.

In Canadian installations, the minimum distance to
be maintained from the inside wall of the pool or spa is
3 meters (approx. 10 feet).

Pour les installations canadiennes, la distance
minimale à maintenir du mur intérieur de la piscine ou
du spa est de 3 mètres (approximativement 10 pieds).

2.2.3 Equipment Pad

Place the heat pump on a flat slightly pitched

surface, such as a concrete or fabricated slab (pad). This
allows proper drainage of condensation and rain water
from the base of the unit. If possible, the pad should be
placed at the same level or slightly higher than the filter
system equipment pad.

NOTE Ensure that the pad is pitched not more than ¼

inch per foot toward the compressor end (front)
of the heat pump. Pitch slab from back to front
¼ inch per foot maximum and level from side to
side.

2.2.4 Condensation and Drainage

Condensation will occur from the evaporator coil
while the unit is running and drain at a steady rate,
usually three to five gallons per hour, depending upon
ambient air temperature and humidity. The more humid
the ambient conditions, the more condensation will be
produced. The bottom of the unit acts as a tray to catch
rainwater and condensation. Keep the drain hole located
on the right side of the base of the unit clear of debris.

If the heat pump is installed indoor a means of
condensate disposal must be provided. The drain hole
in the base of the heat pump is tapped to fit an optional
3/4” diameter barbed adapter, Jandy p/n R3004100 (see
Section 9, “Replacement Parts”). If using the barbed
adapter, connect a length of 3/4” tubing (5’ is included
in Jandy p/n R3004100) to the adapter, then route it
into a drain or outside the building to dispose of the

condensate. It is important to remember that no part of

the tubing or hose may be above the level of the drain
hole in the base of the heat pump.

2.2.5 Lawn Sprinklers

Keep lawn sprinkler heads from spraying on the
heat pump to prevent corrosion and damage. Use a
deflector if needed.

2.2.6 Roof Run-off

Make sure the heat pump is not located where
large amounts of water may run-off from a roof into
the unit. Sharp sloping roofs without gutters will allow
massive amounts of rain water, mixed with debris from
the roof to be forced through the unit. A gutter or down
spout may be needed to protect the heat pump.

2.2.7 Installation of Anchor Clamps

In Florida, building codes require that the heat
pump be anchored to the equipment pad or platform
to withstand high wind pressures created during
hurricanes.

This heat pump was provided with anchor clamps
designed to hold the unit to the equipment pad in high
wind conditions. Installation of the anchor clamps is
recommended in all installations and are required in
Florida (reference Florida Building Code, Mechanical
Section 301.13).

To install the anchor clamps:

1. Be sure that the heat pump is in its permanent

location on the equipment pad.

2. Remove the anchor clamps from the installation

and instruction package.

NOTE: Bolts and bolt anchors are not included with

the heat pump. Jandy recommends that a
1/4” x 1½” long stainless steel Tapcon® type
concrete screw is used to mount the clamp
to the equipment pad. The Tapcon type
concrete screw meets Florida building code
requirements.

3. Place the clamps at the base of the heat pump in

the locations indicated in Figure 2.

6. Drill a hole in the cement using a masonry drill
bit, with a diameter as determined by the concrete
anchor, at each of the marks on the equipment pad.
The hole should be approximately 1-1/2” deep.

7. Insert a bolt anchor into each of the holes. Be sure
the anchors are set completely into the holes.

8. Position the anchor clamps so that the holes in the
clamps are over the bolt anchors. Be sure that the
clamp hooks are over the lip of the heat pump base
(see Figure 3).

Figure 2. Anchor Clamp Positions
NOTE: To Install the brackets on the front of the heat

pump, the front cover must be loosened enough
in order to place the bracket over then lip of
the base. Be sure to re-tighten the front jacket
panel to the heat pump.

4. Fit the hook of each clamp over the lip on the
base panel of the heat pump. The hook should
fi t between the lip of the base panel and the
evaporator coil guard (see Figure 3).

9. Insert an anchor bolt through each clamp into the
anchor and tighten to secure the clamp and heat
pump to the equipment pad.

Section 3. Water Connections

3.1 Plumbing Layout

Figure 4 illustrates the standard plumbing layout

with a single heat pump unit. Following the diagram
from right to left, the plumbing sequence is as follows:

Pool > Pool Pump > Filter > Heat Pump > Check

CHECK VALVE

Figure 4. Standard Plumbing Layout

The heat pump must be protected from back­siphoning of water. If there is any chance of back­siphoning, provide a check valve between the pool
and the filter pump inlet. Arrangement of pool system
components other than as illustrated in the preceding
and following diagrams can affect the operation of the
heat pump’s water pressure switch. Location of the heat
pump above or below the pool water surface can also
affect operation of the switch. In general, the pressure
switch can be adjusted to accommodate this effect if the
heat pump water connections are no more than five feet
below the pool water surface or no more than 11 feet
above it. See instructions for pressure switch adjustment
(Section 5.7) in the heat pump start-up section of this
manual for more information. If the heat pump is
installed outside of this range, an external flow switch
may need to be installed in the plumbing upstream of
the heat pump. Call the Jandy Heat Pump Technical
Service department at [phone] for details.

Be advised that when pool equipment is located
below the pool surface a leak can result in large scale
water loss or flooding. Jandy cannot be responsible for
such water loss or flooding or the damage caused by
either occurrence.

3.2 Water Connections at Heat Pump

Shipping plugs have been installed in the water
inlet and outlet ports of the heat pump at the factory.
Before installing any plumbing, remove the shipping
plugs. Filtered water is plumbed to the inlet, located on

the right side of the heat pump front panel. Heated water
flows through the outlet, located on the left side of the
heat pump front. Two inch unions are provided.

CAUTION

Make sure that fl ow requirements and pool
water turn over rates can be maintained with
the installation of additional heat pumps and
plumbing restrictions.

ATTENTION

Assurez-vous que la circulation d’eau requise
soit maintenue même si des pompes d’appoints
ou des éléments de plomberie, causant des
restrictions, sont ajoutés.

PRECAUCIÓN

Asegúrese de que los requerimientos de fl ujo

3.3 Check Valve Installation

The heat pump must be protected from back­siphoning of water. If there is any chance of back­siphoning, provide a check valve between the pool and
the filter pump inlet.

When an automatic chemical feeder is installed
in the plumbing, it must be installed downstream of the
heat pump. A check valve must be installed between
the heat pump and the chemical feeder to prevent back­siphoning of chemically saturated water into the heat
pump where it will damage the components.

Page 9

3.4 Automatic Flow Control Valve

The inlet/outlet header of the AE-Ti heat pump
comes equipped with an internal automatic flow control
valve. The automatic flow control valve maintains
the proper flow through the heat pump at rates up to
approximately 125 gpm (475 lpm). If the filter system
flow rate is higher than approximately 125 gpm (475
lpm), install a manual bypass valve (see Figure 4).

NOTE Be advised that if your circulation pump is

over 2 HP or if the total fl ow exceeds 125
gpm, you will have to add an external bypass
valve. Excess water fl ow will damage the heat

exchanger.

In certain regions of the country it may be more
economical to run a heat pump during the warmer
months and a gas heater during the cooler months. In
some situations it may be desirable to run the heat pump
in the “Chiller” mode during the hottest portion of the
year and a heater during the cooler months. The Jandy
heat pump may be plumbed with a gas or electric heater
or any combination of heat sources including solar.
All heat sources must be plumbed in parallel to work
correctly and efficiently.

Figure 5 illustrates a recommended plumbing
layout for a heat pump / heater / solar combination
heating system for a pool / spa combination. Your
system may not contain all of these components, but the
basic plumbing will apply by eliminating the component
in the illustration that is not a part of your system.

3.5.2 Multiple Heat Pump Connections

All plumbing on multiple heat pump installations
must be done in parallel (see Figures 6 through 9). An
equal flow of water to each heat pump is important for
optimum operation.

NOTE It may be necessary to adjust water pressure

switch if a unit is installed below the water level.
See Section 5.7 for details on when and how to
adjust the pressure switch.

NOTE Each heat pump allows a maximum fl ow rate of

125 gpm and requires a minimum of 30 gpm.
