INTRODUCTION
This manual
This manual includes the necessary information to or damage safely install and maintain
your Heat Pump. Please read this manual carefully before you operate the unit.
The Heat Pump
The swimming pool heat pump is one of the most economical ways of heating your swimming
pool efficiently. Using the free renewable energy from the air, it is over 4/5 time more efficient
than traditional heating. The swimming pool heat pump extends your swimming season and gives
you comfort at high level. You could enjoy swimming not only in summer,but also in spring, autumn
and even winter time.
ECO Friendly
The Heat Pump uses R410A Refrigerant which is ozone friendly dramatically reducing Carbon
Emissions.
Titanium heat exchanger
The advanced titanium heat exchanger guarantees a longer life span, free of corrosion. It can be
used with all types of water treatment including chlorine, iodine, bromine and salt water.
Multiple functions
- Cooling and heating functions available
- Auto operation, Auto-restart, Auto defrost
- Auto timer on/off:no human attendance is required
- Wide ambient working range: -10°C to 43°C
Reliable operation
The Heat Pump has several built in safety features, which include insufficient water flow
protection, high/low pressure protection, overload protection, compressor protection.
Self-diagnosis
When there is malfunction,the swimming pool heat pump will make self-diagnosis by
displaying error code on the control panel. To identify the problem, please refer to
ERROR CODES pages in this manual.

The following information is for guidance only.
Locating the Unit
The unit should be located on a solid, flat, horizontal surface. Ensure 3 metres of free air
flow to the discharge panel and 1metre to the inlet panel. Ensure adequate access to the
controller and for maintenance purposes.
Precautions
--Avoid locating the unit close to bedrooms or other noise sensitive areas.
--Avoid a location which could create vibration i.e. secured to a solid wall.
--Try to avoid placing the unit under a tree or exposed to extreme conditions.
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.
If your installation is equipped with a water treatment system (chlorine, bromine, saltetc)
the by-pass must be installed before the water treatment, with a non-return valve
between the by-pass and water treatment system.

RENEWABLE HEATING & COOLING TECHNOLOGY

MAINTENANCE
To protect the paintwork, avoid leaning or putting objects on the shell. External Heat
Pump parts can be wiped with a damp cloth and domestic cleaner. (Warning: Never use
cleaning agents containing sand, soda, acid or chloride as these can damage the
surfaces.)
To prevent blockages in the titanium heat exchanger, ensure that the system
incorporates a water and filter treatment facility. In the event of a problem occurring due
to contamination, the system should be cleaned as described below. (Warning: the fins
on the finned tube heat exchanger are sharp!).
Cleaning the Heat Exchanger and Pipework
Contamination in the pipes and heat exchanger can reduce the performance of the heat
pumps’ titanium heat exchanger. If this is the case, the pipe system and heat exchanger
must be cleaned by a technician.
Use only pressurized drinking water for cleaning.
Cleaning the air system
The finned heat exchanger, fan and condensate outflow should be clear of all
obstructions (leaves, twigs, etc.) before each new heating season. These can be
manually removed using compressed air or by flushing with clean water.
It may be necessary to remove the unit cover and air inlet grid first.
Attention: Before opening the unit, ensure that all electrical supplies are isolated.
To prevent the evaporator and the condensate tray from being damaged, do not use hard
or sharp objects for cleaning.
Under extreme weather conditions (e.g. snow drifts), ice may form on the air intake and
exhaust air outlet grids. If this happens, the ice must be removed in the vicinity of the air
intake and exhaust air outlet grids to ensure that the minimum air flow rate is maintained.
Winter Shutdown.
To prevent frost damage to the unit when not in use the Heat Pump should be drained of
all water. Failing this another form of frost protection should be considered and actioned.
Attention: The warranty does not cover damage caused by inadequate frost
protection measures during the winter.
