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.

INSTALLATION
Installation guidelines
The following information is for guidance only.
Locating the Unit
The unit should be located on a solid, flat, horizontal surface. Ensure 3 meters of free air flow to the
discharge panel and 1 meter 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, salt etc.) the by-pass must
be installed before the water treatment, with a non-return valve between the by-pass and water treatment
system.
9
Electrical connection
The Electrical supply must correspond to that indicated on the appliance.
All supply cables have to be sized according to the appliance power and installation requirements.
Please refer to below table:

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,
19
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.
TROUBLESHOOTING
This section provides useful information for diagnosing and correcting certain problems which may
occur. Before starting the troubleshooting procedure, carry out a thorough visual inspection of the unit
and look for obvious defects such as loose connections or defective wiring.
Before contacting your local dealer, read this chapter carefully. It could save you time and money.
WHEN CARRYING OUT ANY MAINTENANCE ENSURE ADEQUATE PRECAUTIONS ARE TAKEN TO
PREVENT AN ELECTRIC SHOCK.
The hints below are for guidance only. If you cannot solve the problem, consult your installer/local
dealer.
The Heat pump will not run.
Please check:
➢ There is a supply voltage (tripped fuse, power failure).
➢ The switch on the wired controller is switched on, and whether the correct set point temperature
has been set.
The set temperature level cannot be reached.
Please check whether:
➢ The permissible operating conditions for the heat pump have been adhered to (air temperatures
too high or too low).
➢ The air inlet or outlet area is blocked, restricted or very dirty.
➢ There are closed valves or stop-cocks in the water pipes.
