Safety precautions
1) Prevention of explosion and fire
Some parts of heat pump (indoor unit) can become very hot.
Do not touch any pipes of heating system which have no thermal insulation.
Do not remove any parts of casing.
2) Prevention of frostbites
Supplied heat pump (indoor unit) is charged with refrigerant R407c. This refrigerant contains no chlorine and
thus represents no damage for ozone layer of the Earth. Refrigerant R407c is not inflammable and forms no
risk of explosion. But leaking refrigerant can cause frostbites on affected areas.
In case of refrigerant leak do not touch any part of heat pump.
Do not inhale fumes or gases, which come out from leaks.
Prevent contact refrigerant with skin or intrusion into your eyes.
When there is a refrigerant contact with a skin or intrusion into eyes, search for medical assistance.
3) Prevention of injuries
The air coming out from the outdoor unit is colder than outdoor temperature. By temperatures below 5 °C
can come to ice forming in this area. This ice represents a certain danger of slipping.
Do not forget possible ice forming under the outdoor unit. Take necessary measures to prevent possible
danger to persons near the outdoor unit.
4) Prevention of injuries due to unqualified modifications
Do not damage or remove seals and safety locks on individual parts of the unit. Modifications of sealed and
locked parts can be done only by authorized service engineers and customer service.
Prohibition to make any changes is valid for:
– heat pump system,
– surroundings of heat pump system,
– water and electricity supply.
Please make under no circumstances any modifications or changes in the heat pump system or in other
parts of heating system and hot water preparation.
Please do not make any additional site structural changes, which could restrict available space for the unit or
other steps, which could lead to a temperature changes on indoor unit installation place.
5) Prevent possible damages to the house caused by condensate water
Piping system between indoor and outdoor is cold which means the condensate can form on piping inside
the house. This could lead to a material damage, e.g. as a result of corrosion.
Please make sure the piping insulation is not damaged.
When there is a insulation damage, please call service engineer immediately.
6) Prevent environment damage
Heat pump (indoor unit) contains refrigerant R407c. This refrigerant must never escape into the atmosphere.
Refrigerant R407C is a fluorinated greenhouse gas with GWP 1653 (GWP = Global Warming Potential)
covered by the Kyoto Protocol. If this refrigerant escapes into the atmosphere, its effect is 1653 times
stronger than the natural greenhouse gas CO

.
Before disposal of the heat pump, refrigerant in the system must be completely sucked up into a suitable
container in order to have later the possibility to recycle or to dispose the refrigerant according to the valid
rules and regulations.
Please ensure all maintenance work connected with access to the refrigerant circuit is made only by officially
certified qualified persons and using corresponding protection tools and equipment.
Please let the refrigerant in the heat pump system to be recycled or disposed by a qualified person in
accordance with valid rules and regulations.
Please consult all matters related to the installation, repairs, dismantling or moving the unit with the
authorized supplier. Wrong made installation can lead to water or refrigerant leak, risk of electrical shock or
fire.
