INTRODUCTION
This manual
This manual includes the necessary information about the unit. Please read this manualcarefully before
you use and maintain the unit.
The unit
The swimming pool heat pump is one of the most economical systems to heat the swimming pool
efficiently. Using the freerenewable energy from the air and the earthit delivers up to five times more
energy in heating than a traditional heating system such as gas heateror electric element heater.Soyou
willsave 4/5cost of the traditional heating. The swimming pool heat pump lengthens yourswimming
seasonand gives you comfort at a high level. You could enjoy swimming not only in summer, but also in the
spring, autumn and even through the winter season.
Ecological and economical heating
By making use of the renewable energyin the outside air, it consumes much less energy withlow
carbon emission. Use environment friendly advanced refrigerant R32 which has little to no effect on
Ozone.
Titanium heat exchanger
Advanced titanium heat exchanger ensures a long life span of heat pump free from corrosion and rust.
By using of titanium heat exchanger the heat pump could be applied with all types of water treatment
such as chlorine, mineral, bromine and salt water pools andspas.
Multiple functions
-Cooling and heating ,Auto functions available;
-Auto operation, Auto-restart, Auto defrost
-Timer on/off: no human attendance is required
- Wide ambient working condition: -15°C to 46°C
Reliable operation
To guarantee the stable running and increase the sustainability of the unit multiple protection devices
have been built into pool heat pump which includes insufficient water flow protection, high/low
pressure protection, overload protection & compressor protection.

3
Safe use
The swimming pool heat pump works without oil, gas (petroleum) or other hazardous substance
which avoid potential risk that goes together. Moreover no gas (petroleum) connection or a fuel
tank is needed. No risk of intoxication, smellorpollution from leakage of such chemicals.
Self-diagnosis
When there is malfunction, the swimming pool heat pump will make self-diagnosis bydisplaying error
code from the control panel. The problem could be found out at a glance be referring to the
troubleshooting section of this manual.

INSTALLATION
Installationinformation
The following information given here is not an instruction, but simply meant to give the user a better
understanding of the installation.
Condition of installation
The following information given here is not an instruction, but simply meant to give the user a better
understanding of the installation.
Installationplace
Install the swimming pool heat pump on a flat, horizontal, and stable surface. Maintain 1 M of open space in
front of the discharge grids and 3 M on the outlet side of the ventilator. And reserve enough space to allow
access to temperature controller.
Make sure that the discharged air will not be breathed in.
To perfect your installation
--Avoid directing the flow of ventilated air towards a sensitive noise zone, such as room window.
--Avoid positioning pool heat pump on a surface that can transmit vibrations to dwelling.
--Try to avoid placing appliance under a tree or exposed to water or mud, which would be likely to complicate
maintenance.
Water connection
The heat pump is connected to a filtration circuit with a by-pass.
It is imperative that the by-pass is placed after the pump and the filter. The
by-pass generally consists of 3 valves.
This makes it possible 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 flow of filtered water.

To channel condensation flows, we recommend that you install our condensate drain kit.
For this purpose the heat pump must be raised by at least 10 cm.
How to install the condensate drain kit?
1. Install your heat pump by raising it by at least 10 cm using solid, moisture-resistant studs.
2. Connect the exhaust hose to the drain hole located underneath the heat pump.
Hydraulic Connection

13
Electrical connection
Electrical supply must correspond to that indicated on theappliance.
Unit must be earthed
Wiring must be completed by a licensed electrician
Set leakage protector according to local code
Connection cables have to be sized according to appliance power and installation requirements. Please
The filter must be cleaned regularly to ensure that the water in the system is clean and to avoid any
problems relatedto dirt or clogging of the filter.
