INTRODUCTION
This manual
This manual includes the necessary information about the unit. Please read this manual carefully before
you use and maintain theunit.
The unit
The swimming pool heat pump is one of the most economical systems to heat the swimming pool
efficiently. Using the free renewable energy from the air and the earth it delivers up to five times more
energy in heating than a traditional heating system such as gas heater or electric element heater. So you
willsave 4/5cost of the traditional heating. The swimming pool heat pump lengthens your swimming
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 energy in 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 and spas.
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 to46°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.
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, smell or pollution 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.
