1. FOREWARD
The Davey heat pump uses eco-friendly R32 gas and step-less DC inverter technology which allows heat to
be extracted from the surrounding air more efciently. This heat is transferred to the pool water by a twisted
titanium heat exchanger. This method generates substantial energy savings compared to: a conventional
electric resistance heater, and natural, or propane gas pool heaters.
2. SAFETY PRECAUTIONS
We have provided important safety messages in this manual and on your heat pump.
Please always read and obey all safety messages.
Environmentally friendly R32 Refrigerant is used for this heat pump.
2.1 Warning
WARNING: Low velocity burning material.
R32 Gas
The WARNING sign denotes a hazard. It calls attention to a procedure, practice,
or the like, which, if not correctly performed or adhered to, could result in personal
injury or injury to a third party. These signs are rare, but are extremely important.
WARNING: Do not use means to accelerate the defrosting process or to clean other than
those recommended by the manufacturer.
The appliance shall not be stored near any ignition sources (for example; open ames, an
operating gas appliance or an operating electric heater.
Do not pierce or burn.
Be aware that refrigerants may not contain an odour.
R32 Gas
INSTALLATION REMINDERS:
The installation of any pipework should be kept to a minimum.
Pipework should be protected from physical damage and shall not be installed in an
unventilated place.
The heat pump should not be installed indoor.
Any mechanical connections need to be kept accessible for maintenance purposes.
The heat pump requires 50cm clear space on each side to be clear from obstructions for
ventilation purposes.
Any maintenace or service needs to be carried out in compliance with national
gas regulations.
QUALIFICATION OF WORKERS: A technician with a Refrigerant Handling Licence should
carry out any service or maintenance carried out on the heat pump refrigerant equipment.
A registered electrician should carry out any service or maintenance required for the heat
pump electrical equipment.
2.2 Attention
a. Please read the following instructions before installation, use and maintenance.
b. Installation must be done by professional staff only in accordance with this manual and any
local regulations.
c. Leakage test must be performed after installation.
d. Please don’t stack substances, which will block air ow near inlet or outlet area, otherwise the efciency of
the heat pump will be reduced or even stopped.
4
e. Set proper temperature in order to get a comfortable water temperature to avoid overheating or
overcooling.
f. In order to optimize the heating effect, please install heat preservation insulation on pipes between
swimming pool and the heat pump, and please use a recommended cover on the swimming pool.
g. Connecting pipes of the swimming pool and the heat pump should be ≤10m.
h. Except for the methods recommended by the manufacturer, do not use any methods to accelerate the
defrosting process or clean the frosted parts.
i. If a repair is required, please contact the nearest after-sales service centre. The repair process must be
strictly in accordance with manual. All repair practice by non-licensed personnel is prohibited.
j. Don’t use or stock combustible gas or liquid such as thinners, paint and fuel to avoid re.
2.3 Safety
a. Please keep the main power supply switch far away from children.
b. When a power outage happens during operation, the heat pump will start when the power is restored..
c. Please switch off the main power supply in lightening and storm weather to prevent from damage caused
by lightning.
d. Safety inspection must be carried before the maintenance or repair of heat pumps with R32 gas in order to
minimize the risk.
e. Installation and any repairing should be conducted in an area with adequate ventilation and with no nearby
ignition sources.
f. If R32 gas leaks during the installation process, all operations must be stopped immediately and call the
service centre.
WARNING: Do not use means to accelerate the defrosting process or to clean other than
those recommended by the manufacturer.
The appliance shall not be stored near any ignition sources (for example; open ames,

4. INSTALLATION GUIDANCE
4.1 Installation reminder
The installation of this product should be carried out by a person knowledgeable in swimming pool plumbing
requirements following the installation instructions provided in this manual.
To get the best results from your Davey heat pump, its location is critical. The Davey heat pump takes hot air
from its surroundings and transfers this heat through its heat exchanger, to the pool water.
Your Davey heat pump should be installed in a well ventilated area.
WARNING: Improper installation, adjustment, service, maintenance or use can cause re,
electrical shock or other conditions which may cause injury or property damage. Consult
a qualied technician or service agency for information or assistance. All service calls
under warranty should be authorized by Davey Water Products.
The installation of any pipework should be kept to a minimum
Pipe work should be protected from physical damage and shall not be installed in an
unventilated place.
The heat pump should not be installed indoor.
Any mechanical connections need to be kept accessible for maintenance purposes.
The heat pump requires 50cm clear space on each side to be clear from obstructions for
ventilation purposes.
The heat pump draws air in through each side of the heat pump and out through the rear.
Please consider this during installation.
For installations up to 17kW
8
For installations 21kW and over
Installing into main ltration system
Installing into existing solar heating system
1) The frame must be xed by bolts (M10) to concrete foundation or brackets. The concrete foundation must
be solid and fastened; the bracket must be strong enough and antirust treated;
2) Please ensure 50cm of clearance around each side of the Davey heat pump or the efciency of the heat
pump will be reduced;
3) Although a bypass system is not necessary for your Davey heat pump to operate properly, we strongly
recommend the installation of a bypass system to regulate the ow rate and make the maintenance and
winterising of the Davey heat pump easier.;
9
4) When the heat pump is running, there will be condensation water discharged from the bottom. Please use
the drainage kit supplied.;
5) Your Davey heat pump must be connected with hard pipes.
6) Any pipework installation should be kept to a minimum and protected from physical damage.
7) If the Davey heat pump will be in operation over winter, Davey recommends it is installed on the main
ltration system to avoid heat loss through the solar heating system.
4.2 Wiring
WARNING: The electrical connection should be done by a qualied electrician according
to national, state and local city codes, regulations or standards.
The unit should be connected to a compatible RCD (Residual Current Device).
Means for full disconnection of the power supply must be incorporated in the xed wiring
in accordance with the wiring rules.
