Inverter Heat Pump Owner’s Manual
Installation
Installation
Only a qualified service person should install the Ecoclear® TM Heat Pump. Before installing this
product, refer to the Important Warning and Safety Instructions on page 4.
Materials Needed for Installation
The following items are needed and are to be supplied by the installer for all heat pump
installations:
1. Plumbing connections (50mm).
2. Level surface for proper drainage.
3. Suitable electrical supply line. See rating plate on unit for electrical specifications. A junction
box is not needed at the heat pump; connections are made inside of the heat pump electrical
compartment. Conduit may be attached directly to the heat pump jacket.
4. Electric isolation switch that will interrupt all power to the unit. This switch must be
within line of sight of the heat pump. Check local codes and wiring rules AS/NZS 3000 for
requirements.
5. Watertight conduit to run the electrical supply line.
Equipment Pad
For proper drainage of condensation and rain water, place the heat pump on a flat slightly
pitched surface, such as a concrete or fabricated slab (pad). If possible, place the pad at the
same level or slightly higher than the filter system equipment pad.
Note: Be sure that the pad is pitched not more than 20mm per metre in any direction as
needed for runo.
Drainage and Condensation
Condensation occurs from the evaporator coil while the unit is running, and drains at a steady
rate (up to 20L 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 holes, located on the
bottom pan of the base of the unit, clear of debris.
Roof Run-o
Make sure the heat pump is not located where large amounts of water may run-o 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.
Lawn Sprinklers
Avoid placing lawn sprinkler near the heater - they can spray water into the heater and void
the warranty. Be sure to direct any spraying water away from the heater. Note the wind
direction to be sure water from sprinklers is not blown toward the heater. Sprinkler heads
can produce high water pressure and spray at an angle, dierent from typical rain and humid
weather. Also, sprinklers connected to a well water system can cause mineral build up on the
evaporator coils and electronics.
Coastal Environments
Salt spray from coastal environments can cause corrosion of certain heat pump components,
which is not covered by warranty. Care and attention should be taken to locate the heat pump
to avoid salt spray from the surrounding environment.

10 Inverter Heat Pump Owner’s Manual
Location and Clearances
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. The Ecoclear® Heat Pump
must be placed to provide clearances on all sides for maintenance and inspection.
1. At least 2.5m access must be available in the front and 300 mm on all the other sides of the
heat pump for service and proper air flow. (Manufacturer’s recommendation).
2. If the heat pump is to be installed under a cover or under a vertical overhang, the unit must
have a minimum of 500mm clearance from the top of the heat pump. (Manufacturer’s
recommendation).
3. Install a minimum of 3.5m from the inside wall of the pool or spa unless the heat pump is
separated from the pool or spa by a 1.8m high solid fence or other permanent barrier.
4. Install heat pump a minimum of 300mm from the wall of the house.
5. Allow 500mm clearance above the heat pump for service access.
6. Base must be level. It is important that condensate and rain water will drain away from the
drip tray. Any unevenness in the base will cause water to pool in the drip tray and corrosion
may occur.

Anchor Clamp Installation
Installation of the anchor clamps is recommended in all installations. Anchor clamps hold the
heat pump to the equipment pad in order to withstand high winds, accidental movement and
excessive vibration.
To install the anchor clamps:
1. Be sure the heat pump is in its permanent location on the equipment pad.
2. Locate the clamps at the base of the heat pump in the four (4) locations, shown in the
image to the right.
Note: Bolts and bolt anchors are not included with the heat pump. The installer must
provide 1/4” x 1-3/8” stainless steel anchor bolts and the appropriate size concrete anchor to
mount the clamp to the equipment pad. Be sure to check local codes.
3. Fit the anti-vibration pad (included) under each anchor clamp.
Installation

11
Inverter Heat Pump Owner’s Manual
4. Mark the position of the hole in each clamp on the equipment pad.
5. Use a masonry drill bit and drill a hole in the cement with a diameter as determined by
the concrete anchor, at each of the marks on the equipment pad. The hole should be
approximately 40mm deep.
6. Insert a bolt anchor into each of the holes. Be sure the anchors are set completely into the
holes.
7. 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.
8. Insert an anchor bolt through each clamp into the anchor and tighten to secure the clamp
and heat pump to the equipment pad.

Plumbing Connections - Standard
The image below shows the standard plumbing layout with a single Ecoclear® Inverter Heat
Pump unit. Arrangement of pool system components (other than the standard plumbing im-
age below), can aect the operation of the heat pump.
Note: Be advised that when pool equipment is located below the pool surface a leak can re-
sult in large-scale water loss or flooding. Maytronics is not responsible for such water loss or
flooding or damage.
The heat pump should be connected to a filtration circuit through a by-pass which consists of
3 valves. It is imperative that the by-pass is placed after the pump and the filter. These valves
allow to regulate the water flow which passes through the heat pump and to isolate the heat
pump completely for any maintenance work, without cutting the filtration flow.
If your installation is equipped with water treatment devices (chlorine, bromine feeder, salt
water chlorine generator, others) the by-pass must be installed before the water treatment
devices, with a non-return check valve between the by-pass and water treatment devices.
Water inlet and outlet are designed to be connected to rigid pressure PVC tube (for swimming
pool) 50mm, directly glued to the union connectors provided.
Water pipes must be fixed on the floor or the walls, so the heat pump will not support the
weight of the water inside the plumbing.

The Ecoclear® Inverter Heat Pump can also be connected on plumbing separate to the main
filtration system. In this configuration the pump will take water from separate pool outlets and
flow directly into the heat pump. A filter is not essential in this configuration, however it may
be required in circumstances where there is large debris in the water, or poor water quality,
which could cause blockages in the heat pump.

Figure 6: Plumbing Connections - Separate Circulation System
The heat pump should be connected through a by-pass which consists of 3 valves. These
valves allow to regulate the water flow which passes through the heat pump to optimise
performance and also to isolate the heat pump for service. The valve network is not required
when using a variable speed pump, in this configuration, as the pump can be adjusted to opti-
mise the flow through the heat pump.
When installing the pool plumbing for this configuration, at least two pool outlets shall be
used with minimum separation as per AS1926.3. Ensure that the plumbing configuration of the
pool outlets and the pool outlet covers are compliant to AS1926.3.
Figure 7: Twin Safety Suctions
In this configuration, the circulation pump can be powered by the heat pump. Refer to the
electrical wiring diagram for connection details and ensure this work is undertaken by a quali-
fied electrician in accordance with the wiring rules.

Electrical Connections
General Information
Wiring connections must be made exactly as shown in the wiring diagram found on the inside
of the heat pump access panel; see the wiring diagrams on page 35.
The Ecoclear® Inverter Heat Pump must include a definite means of grounding and bonding.
There is a ground lug inside the heat pump electrical compartment.
Equipotential Bonding
The Wiring Rules (AS/NZS 3000) and most other codes require in many circumstances that
metallic components of a pool structure, including reinforcing steel, metal fittings, and above
ground equipment be bonded together with a solid copper conductor. The heat pump contains
a metal (titanium) heat exchanger which is in contact with the pool water, which may need to
be connected to this bonding grid. A bonding lug is provided to ensure this requirement can be
met. Please refer to the Wiring Rules (AS/NZS 3000) and any local codes for details on wheth-
er equipotential bonding is required.
Main Power
Electrical wiring to the heat pump must be in accordance with the latest edition of the Wiring
Rules (AS/NZS 3000). All wiring must be done by a certified or qualified electrician.
Power to the heat pump must be protected by an RCD or RCBO. The heat pump should be the
only device connected to the protected circuit. For high power model heat pumps (16kW-24kW)
it may be necessary to use a D-Curve type RCD/RCBO to avoid nuisance tripping with com-
pressor starts.
The following is the procedure to wire the heat pump to the electrical source:
Be sure the power to the circuit for the heat pump is turned o.
1. Remove the front panel of the heat pump cabinet (you need to loosen the front screws on
the top panel aswell).
2. Remove the service panel to the heat pump electrical compartment.
3. Electrical supply lines must be run through watertight conduit on the front panel. Run the
wires and conduit from the power source and connect them to the conduit connection. Use
suitable gauge connection wire as per below table.
4. Connect the power leads to the terminals in the electrical compartment as shown in the
wiring diagram.
5. Verify that all other wires are secure, they may have loosened during shipment.
6. Connect the ground wire to the ground lug provided.
7. Replace the service panel and reinstall screws to hold it in place.
8. Replace the front panel.
