CAUTION
Do notinstall the unit in a place where flammable gas leak can occur.
All plumbing connections should be carried out as per the instructions inthis manual.
Failure to do so could result inwater damage to property.
Avoid contact with the fan when the unitis operating as this will cause serious injury.
Ensure the Heat pump is correctly grounded to earth withthe power cable.
Locating the Heat pump
TheHeat pump should NOT be installed in an airtight location or confined space, such as a basement or garage.
TheHeat pump requires good air ventilation. It will discharge cold air when it is heating and hot air when it is
cooling, and its efficiency depends on its ability to draw normal ambient temperature air and discharge the
cold or hot air well away fromthe unit. It is recommended to install the Heat pump away from any other home
appliances, to avoidthe chance of electromagnetic interference. Please refer to the "Air space requirements"
section ofthis manual.
Theunitshould be located on a solid flat surface with a slight rearward slope. Ensure 3 meters (9feet) of free airflow to
thedischarge panel and1meter (3 feet) to the inlet panel as well as free airflow to all sidesof the unit. Ensure adequate
access for maintenance purposes.
In cold climates, the Heat pump should be installed at least 46 cm (18'') above the ground level on an open metal frame
in orderto prevent the accumulation of iceat the base of the unit caused by condensation. Your Heat pump specialist
may recommend adedicated frame rusted proof. See alsorecommendations inthe Condensation section further.

Installation
Precautions
• Avoid locating the unit close to bedrooms or othernoisesensitive areas.
• Avoid a location which could create vibration(e.g. secured toasolidwall).
• The fan should not blow towards windows,walls or spaces likely to be inhabited by people or animals.
• Do not install where the Heat pump is likely to be subjected to polluted air, dust or debris, etc.
• Avoid directing fan output against the dominant wind directions.
• Protectthe heat pump from possible snow fall.
• Minimise exposure to environmental conditions as much as possible and never block the airflow.
Securing the Heat pump
TheHeat pump should be securely fixed. The four included rubber mounts should be installed to absorb
high-frequency vibrations.
Piping
A bypass, consisting of threevalves, must be installed to adjustwater flow to the Heat pump and to isolate the
apparatus for maintenance purpose.
Fora more stable flow in the heat exchanger, itis recommended to install the Heat pump on the pressure side of the
main pump.
If your installation is equipped withawater treatment system (chlorine, bromine, salt, etc.) the bypass must beinstalled
before the watertreatment, with a checkvalve between the bypass and water treatment system.
Condensation
Theair drawn intothe Heat pump is strongly cooled by the operation ofthe Heat pump for heating thespa water, which
maycause condensation on the fins ofthe evaporator. The amount of water may be as muchas several liters per hour
at high relative humidity. This is sometimes mistakenly regarded as awater leak.
Since water generated by condensation will be evacuated at the bottom of the Heat pump, it is better to provide a slight
rearward slope when installing the Heat pump to allow this water toflow freely on the ground. It must also be ensured
that this evacuation of water will not affect any components around the Heat pump like electrical circuit and material like
wood ormetal that can be weakened by water That said, be aware that water will flow under the Heat pump in normal
operation.

Operating modes
Theoperating mode can be changed through the spa user interface.
Six different operating modes are available:
1) EcoHeat(EcoH)
2) Smart Heat (HEAT)
3) Cool (COOL)
4) EcoAuto(AUTO)
5) Smart Auto (SMRT)
6) Electric(ELEC)
Eco Heat (EcoH)
In this mode, the Heat pump is used asthe unique source
of heating. Theheating element is kept off and the Heat
pump is not usedtocool the watershould its temperature
rise above the current set point.
Smart Heat (HEAT)
This mode uses the Heat pump as the main heating
source. Theheatingelement is turned on only if thereis
alarge temperaturedifference between the water and the
set point orifthe ambient temperature gets too low. The
Heat pump is not used to cool the water inthis mode.
Cool (COOL)
This mode uses the Heat pump in cooling mode only.
TheHeat pump is not used as a heatingsource and the
heating element is never activated.
Eco Auto (AUTO)
This mode borrows functionality from both Eco Heat
andCool modes and has the ability to select the proper
Heat or Cool mode automatically according to the water
temperature. The heating element is neveractivated in
this mode.
Smart Auto (SMRT)
This mode borrows functionality from both Smart Heat
andCool modes and has the ability to select the proper
Heat or Cool mode automatically according to the water
temperature. The heating element is activated only if there
is a large temperature difference between the water and
the set point or if the ambient temperature gets too low.
Electric(ELEC)
This mode keeps the heat pump off and uses only the
heating element to regulate water temperature.
FreezeProtection
In cold weather,ifit becomes impossible for the Heat pump to keep the water temperature above freezing point, the
help of theheatingelement might be required even if its use should be prohibited by the operating mode or conditions.
At any time, if the water temperature drops too close to the freezing point, the operating mode will be switched
temporarily to“Smart Heat” andthe system will heatuntil the minimum allowed set point hasbeen reached before
reverting to its previous operating mode and resume normal operation.
Three minutes waiting time
In any circumstances, when the Heat pump is shutdown, pleasebe aware that there is forced waiting time of three
minutes before the Heat pump can operate again. This is so to prevent damage to the equipment. For example, if the
operating mode has been changed from Cold to Hotsucceeding an increase of the setpoint, the Heat pump will be
allowed to start only after a delay of three minutes.

To protectthe paintwork, avoid leaning or putting objects on the shell. Heat pump parts can be wiped with adamp cloth
and domestic cleaner. (Warning: Never use cleaning agents containing sand, soda, acid or chloride as these can
damage the surfaces.)
To prevent clogging in the titanium heat exchanger, ensure that the system incorporatesa water and filter treatment
equipment. In theevent ofaproblem 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 pump. If this is the case, the
pipe system andheat exchanger must be cleaned by a technician. Use only pressurized drinking water for cleaning.
Cleaning the air system
Thefinnedheat exchanger, fan and condenser outflow should be clear of all obstructions(leaves, twigs, etc.) before
each new heating season. These canbe manually removed using compressed air orby flushing with clean water.
It may be necessary to remove the unit cover and air inlet grid first.
Warning: Beforeopening the unit, ensure that all electrical supplies are protected from human access.
To prevent the evaporator and the condenser tray from being damaged, do not use hard or sharp objectsfor cleaning.
Under extreme weather conditions (e.g. snow drifts), ice may form on the airintake and exhaust air outlet grids.
If this happens, the icemust be removed in the vicinity ofthe airintake and exhaust air outlet grids to ensure that
theminimum air flow rate is maintained.
Winter Shutdown
To prevent frost damagetothe unit when not in use the Heat pump should be drained of all water. If the Heat pump
cannot be winterized, anotherform of frost protection should be considered.
Warning: The warranty does not cover damage caused by inadequate frost protection measuresduring the winter.
Maintenance

Steps to winterize your Heat pump
• Turn offall electrical power to the Heat pump.
• Turn offthe circulation pump.
• Disconnect thewater piping inlet and outlet from the Heat pump.
• Remove the drain plug and make sure the heat exchanger drains out.
• TheHeat pump should be blown out with airtoensure no water is left inside. A compressed airline should be placed
into thewater outlet line to blow air through the unit.
• Loosely reconnect the plumbing connection and drain plug to allow any remaining waterto drain but block insects
anddebris.
• Cover the Heat pump with a protective tarp to prevent snow and other debris from going in the fan grill.
• Finally,ensure that all plumbing going from the Heat pump tothe spa hasbeen emptied from all water.
