Safety procedures
Unit installation
Electrical connections
The installation must be carried out by a qualified
installer.
DO NOT INSTALL IN A PLACE...
• Difficult to access for installation and maintenance.
• Too close to heat sources.
• That might increase the vibration of the unit.
• Which cannot bear the weight of the unit.
• Subject to a risk of exposure to a combustible gas.
• Exposed to oils and vapours.
• With particular environmental conditions ie windy
location.
CHOOSE A PLACE...
• Where noise and discharged air do not disturb neighbours.
• Protected from strong winds.
• That allows for the clearances required.
• Which will not obstruct passageways or doors.
• With floor structure adequately strong to support unit
weight and minimize vibration transmission.
Note...
Fix the unit with locally purchased bolts buried in the block.
If the unit is installed in areas where heavy snowfalls may
occur, it is necessary to raise its level at least 200mm above
the usual snow level or alternatively to use the outdoor unit
wall mounting bracket kit. See Kingspan optional extras
such as the “snow feet” (Anti vibration foot KHP0044 )
recommended for exposed areas to help create an air gap
under the unit.
CAUTION
!
!
All field electrical connections are the responsibility of
the installer.
DANGER
Electrical shock can cause severe personal injury
or death. These operations are to be carried out by
qualified personnel only.
!
WARNING
• This unit complies with Machinery Directive
(2006/42/EC), electromagnetic compatibility
(2004/108/EC) and pressure equipment (EEC/97/23)
Directives.
• To avoid electric shock or fire make sure these
operations are carried out by qualified personnel only.
• Ensure that national safety code requirements have been
followed for the main supply circuit.
• Follow all current national safety code requirements.
• Ensure that a properly sized and connected ground wire
is in place.
• Check that voltage and frequency of the mains power
supply are those required; the available power must be
adequate to operate any other possible appliances
connected to the same line.
• Check that the impedance of the mains power supply is
in conformance with the unit power input indicated in
the rating plate of the unit.
• Make sure that properly sized disconnecting and safety
switches are installed.
• The disconnection devices from the mains supply must
allow full disconnection under the conditions provided
for by overvoltage class III.
• Connect the connecting cable correctly. If the
connecting cable is connected in a wrong way, electric
parts may be damaged.
• Connection to the mains supply is of the Y type;
therefore, the cable must only be replaced by a
qualified technician in order to prevent any risk.
• Use the specified cables for wiring and connect them
firmly to the terminals.
• Be sure to provide grounding; inappropriate grounding
may cause electric shock.
• Do not connect ground wires to gas pipes, water pipes,
lightning rods or ground wires for telephone cables.
DANGER:
Do not modify this unit by removing any of the safety
guards or by by-passing any of the safety interlock
switches.
FINAL CHECK
• If refrigerant gas leaks out during the installation work,
ventilate the room immediately.
• If refrigerant gas leaks into the room and flows near a
fire source, such as a cooking range, poisonous gas is
generated.
Contact the manufacturer if one of the following
events takes place:
• hot or damaged power supply cable;
• unusual noise during operation;
• frequent operation of the protection devices;
• unusual smell (such as smell of burning).
