1. General information
1.1 Introduction
This manual provides installation and operation instructions for EVOHEAT heat pumps. Read
these installation and operation instructions carefully before proceeding with the installation
and operation of your heater. Consult your EVOHEAT Distributor with any questions regarding
this equipment.
Installation and service must be performed by a qualied installer. The manufacturer will not
be responsible for any damage to the unit or injury caused by improper installation, operation
or maintenance.
1.2 Consumer and Safety Information
a. Evo recommends 27°C as the optimum water temperature for swimming.
b. The consumption of alcohol or drugs before or during spa or pool use can cause
drowsiness which could lead to unconsciousness and subsequent risk of drowning.
c. Immersion in water exceeding 38°C during pregnancy is not recommended.
d. The water temperature should always be checked with an accurate thermometer before
entering a spa or hot tub.
e. 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.
f. Persons taking any medication or drugs which induce drowsiness (e.g., tranquilizers,
antihistamines, or anticoagulants) should not use spas or hot tubs.
g. Prolonged immersion in hot water can induce hyperthermia.
1.3 Energy Saving Tips
It is important to note that a heat pump will not heat a pool as fast as a large gas pool heater.
If the pool water is allowed to cool signicantly, 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.

a. Use an accurate pool thermometer. A difference of 2°C , between 26°C and 28°C,
will signicantly increase energy consumption.
b. Carefully monitor the water temperature of your pool in the summer time. You can
reduce heat pump usage due to warmer air temperatures.
c. When the pool is not to be used for long periods, turn off the heat pump.
d. Where possible, shelter the pool from prevailing winds with well-trimmed hedges or
other landscaping, cabanas, or fencing.
e. Always use a high quality pool cover when practical. Besides providing a valuable water
saving feature, a pool cover will dramatically reduce heat loss. See attached appendix
for further information.

CHAPTER 1
Installation
Example of a unit with a
refrigerant leak and zero
pressure – notify
Evoheat Dealer.
Before installation it is very important to ensure 4 variables
are carefully checked to allow the unit to operate correctly:
1. Adequate Air Flow
2. Correct water ow volume
3. Correct electrical connection & supply
4. Heater condition
1. Air Flow
Installing the heater indoors or in an enclosed space will result in very poor performance and
can in extreme cases damage the heater. Ensure the heater is installed in a well ventilated
area with plenty of fresh air, a minimum gap between walls/fences etc of 600mm on the
sides and 1500mm overhead clearance.
Important: Ensure that the cold air off the top of the heater does not
recycle through the heater.
SEE PAGE 8 FOR FURTHER INFORMATION
2. Water Flow
It is CRITICAL that there is sufcient water ow to the unit. Incorrect water ow can cause a
loss of efciency and possible damage to the unit. Optimal water ow rates are listed in the
Evoheat sales brochure and in this manual on page 5. It is imperative that water ow is kept
as close as possible to these ow rates. Correct water ow not only offers optimal heater
performance, but may also prevent possible damage to your heater.
SEE PAGE 9 FOR FURTHER INFORMATION
3. Electrical Connection
Always use a qualied Electrician to perform any electrical work. Ensure the power cable and
circuit breaker are of a suitable size for the heater being installed. Also check that there is
adequate voltage and current available at the heater connection to run the unit. Voltage range
should be 220-240 volts for single phase, and 380-415 volts for 3 phase units. Voltage ranges
outside these parameters will cause heater damage and void your warranty. Correct phase
connection is important with 3 phase heaters.
SEE PAGE 10 FOR FURTHER INFORMATION
4. Heater Condition
Check the heater packaging upon delivery for any obvious signs of damage. Inform your
supplier IMMEDIATELY if there is any evidence of rough handling.
When the heater has been removed from the packaging check the refrigerant gauge on the
front panel of the unit. The gauge should be showing a pressure of approx 1Mpa on the
outside black band – any less than this gure means there may be a leak in the refrigerant
system and you should immediately contact your Evoheat Dealer.
3. General installation information
3.1 Inspection
Inspect the packaging, the heater and other items after receipt for possible damage in
transportation. Please contact your EVOHEAT dealer immediately should you suspect any
damage has occurred during transportation.
Install your EVOHEAT heat pump in accordance with the procedures in this manual. Always
check that your installation will comply with local building and council regulations.
12 13
Correct installation is required to ensure safe and efcient operation of your pool heater.
Installation requirements for EVOHEAT heat pumps include the following:
a. Appropriate site location and clearances.
b. Sufcient air ventilation.
c. Correct electrical connection.
d. Adequate water ow.
This manual provides the information needed to meet these requirements.
Review all application and installation procedures completely before
continuing the installation.
3.2 Location
Evo recommend the heat pump should ONLY be installed in an outdoor location with
appropriate ventilation.
In the event that a suitable outdoor location is unavailable contact Evo Industries for
specialist technical advice.
If installing the heater on an existing pump/ltration system the heater must be installed
AFTER the lter and BEFORE the chlorinator/sanitizer.
The heat pump should be installed on a at level surface as close as possible to the pool.
Large runs of uninsulated piping can signicantly contribute to heat loss. A rough estimate
of heat loss over a 30m pipe run can be as high as 600 Watts per hour per 5 degrees of
temperature difference between the air/ground and the pool water. These losses need to
be taken into account over long distances and piping may need to be insulated to reduce
heat leakage.
The heat pump should be installed a maximum of 1m below the water level of the pool/spa.
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 excessive amounts of rain
water mixed with debris from the roof to be forced through the unit. A water deector may
be needed to protect the heat pump.
3.3 Clearances
The unit needs continuous fresh
air whilst running. The heater
draws up to 80m3/min ambient air
through the sides and discharges
through the top fan cowl. Leave
sufcient space for unobstructed
airow into and out of the heater.
Do not locate the heater in an
enclosed area, or the discharged
cold air will recirculate into the
unit and consequently lower the
heating efciency.
3.4 Water Flow and
Plumbing Setup
All EVOHEAT heat pumps have a
factory preset internal water ow
switch. If there is insufcient water
ow the heater will not operate.
Before connecting the heater
to the plumbing, all piping must
be thoroughly ushed to ensure
no debris can enter the heater.
Failure to remove pipe debris
can jam or damage the ow
switch and may cause damage
to the heater.
When cleaning the pool it is
advisable to turn off your heater
as restricted water ow may
cause the heater to shut down
and indicate low water ow fault
(P08 error).

3.5 Water Pump Connection
How do I connect up my new
EVO heater to my pool or spa?
The EVO JBox is the answer. The JBox
will save you money on water pumps
and running costs.
The JBox allows either the heater
OR the chlorinator to supply power
to the water pump so each system
can run independently of the other.
Installation Options
There are 3 methods to install an
Evo heat pump.
1. Slave Mode
Heater is connected to the ltration
system but relies on water ow from
the chlorinator for start and stop times.
Advantages
• Only 1 pump needed – savings on
purchase and running costs.
Disadvantages
• As the heater may need to run
18+hrs a day the chlorinator will
need to be adjusted to allow the
pump to run longer. This can
cause water chemical balance
issues resulting from over or
under chlorinating the pool. You
will need to constantly monitor
and ddle with the chlorinator
output to keep it.
2. Seperate Systems
Heater runs on a dedicated circuit
to the ltration system. The heater
controls the start and stop times
of this pump.
Advantages
• Easy to use – set and forget the heater operation and leave your chlorinator to
work as normal
• No water balance issues due to adjusting the chlorinator running time.
Disadvantages
• Purchase of 1 extra water pump at up to $800
• Electrical use from this pump could add up to over $1000 per year
3. EVO JBox
Heater is connected into the ltration plumbing. After installing the Evo JBox and having your
electrician hard wire the JBox to the heater, simply plug the water pump into the JBox and
plug the JBox into the Chlorintor.
Advantages
• Only 1 pump needed – savings on purchase and running costs
• Save up to $1000pa on electricity
• Easy to use – set and forget the heater operation and leave your chlorinator to
work as normal
• No water or chemical balance issues due to adjusting the chlorinator running time
Disadvantages
• None!
Order an EVO JBox with your heater and relax in your pool while maximising the savings.
3.6 Drainage
Whilst the heater is operating, water in the air condenses on the ns of the evaporator. In
the instance of high humidity, the condensate may be several litres per hour. This may give
the impression that the heater is leaking, however this is a normal function of heat pumps.
The heater will automatically activate reverse cycle or de-icing mode when required which
also increases condensate discharge. This normally occurs at temperatures below 8 degC.
The condensate water will discharge through the base of the heater. As an option a pipe
can be connected to the drain on the base of the unit to direct condensate water to an
appropriate location.

3.7 Electrical Connection
NOTE: EVO heat pumps MUST be connected by a licensed electrician.
Under no circumstances should you attempt to install or repair your
heat pump yourself.
Heater electrical installation undertaken by an unlicensed installer may cause electric shock
or even death, and will void the warranty.
A licensed electrician must read the information in this manual before connecting.
a. Ensure power is disconnected during installation or service.
b. Always comply with the national and local electrical codes and standards.
c. Ensure electrical cable size is adequate for heater requirements at the
installation location.
d. The heater must be equipped with a circuit breaker and isolation device.
e. Circuit breaker must be installed between the heater and the water circulation pump if
the water pump is hard-wired into the heater. Please note recommended circuit breaker
sizes make no allowance for a water pump hard wired into the heater.
f. Evo strongly recommends the installation of a Residual Current Device.
g. The unit must be well earthed.
Remove the front panel to access the electrical connection terminals of the heater.
The electrical wiring diagram is afxed to the inside of the front panel.
SEE APPENDIX “A” FOR WIRING DIAGRAM INFORMATION
3.8 Remote Controller Connection
All Evo heaters are able to be controlled remotely by any device capable of opening and
closing a circuit. The circuit must be low voltage 5V or lower.
Remove the cable loop between DI01 and GND on the pcb and connect the remote cable
from the external controller into these terminals.
When this circuit is open (no connection) the Evo heat pump will not operate. When the
circuit is closed the unit will operate according to the parameters set on the controller(s).
