EKMBUHBA6V3
Heater kit for air to water heat pump system
4PW63549-1A – 08.2010
Accessories:
Equipment which is delivered with the unit and which needs to be
installed according to instructions in the documentation.
Optional equipment:
Equipment which can optionally be combined to the products as per
the subject of this manual.
Field supply:
Equipment which needs to be installed according to instructions in
this manual, but which are not supplied by Daikin.
2. GENERAL SAFETY PRECAUTIONS
All activities described in this manual shall be carried out by an
installer.
Be sure to wear adequate personal protection equipment (protection
gloves, safety glasses, …) when performing installation, maintenance
or service to the unit.
If not sure of installation procedures or operation of the unit, always
contact your local dealer for advice and information.
Improper installation or attachment of equipment or accessories
could result in electric shock, short-circuit, leaks, fire or other damage
to the equipment. Be sure only to use accessories and optional
equipment made by Daikin which are specially designed for use with
the products as of subject in this manual and have them installed by
an installer.
The precautions listed here are divided into the following four types.
They all cover very important topics, so be sure to follow them
carefully.
■ Install the power wire at least 1 meter away from
televisions or radios to prevent image interference or
noise.
(Depending on the radio waves, a distance of 1 meter
may not be sufficient to eliminate the noise.)
■ Do not rinse the heater kit. This may cause electric
shocks or fire.
■ Do not install the heater kit in places such as the
following:
■ Where there is mist of mineral oil, oil spray or vapour.
- Plastic parts may deteriorate, and cause them to fall
out or water to leak.
- Where corrosive gas, such as sulphurous acid gas, is
produced.
- Corrosion of copper pipes or soldered parts may
cause the refrigerant to leak.
- Where there is machinery which emits
electromagnetic waves.
- Electromagnetic waves may disturb the control
system, and cause malfunction of the equipment.
- Where flammable gases may leak, where carbon
fibre or ignitable dust is suspended in the air or
where volatile flammables, such as thinner or
gasoline, are handled.
- Such gases may cause a fire.
- Where the air contains high levels of salt.
- Where voltage fluctuates a lot, such as that in
factories.
- In vehicles or vessels.
- Where acidic or alkaline vapour is present.
DANGER: ELECTRICAL SHOCK
■ Switch off all power supply before removing the
service panel or before making any connections or
touching electrical parts.
To avoid electric shock, be sure to disconnect the
power supply 1 minute or more before servicing the
electrical parts. Even after 1 minute, always measure
the voltage at the terminals of main circuit capacitors
or electrical parts and, before touching, be sure that
those voltages are 50 V DC or less.
■ When service panels are removed, live parts can be
easily touched by accident.
Never leave the heater kit unattended during
installation or servicing when the service panel is
removed.
■ Do not touch the internal parts during and
immediately after operation.
Your hands may suffer burns if you touch the internal
parts. To avoid injury, give the internal parts time to
return to normal temperature or, if you must touch
them, be sure to wear proper gloves.
■ Do not touch any switch with wet fingers. Touching a
switch with wet fingers can cause electrical shock.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PART S
Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.
Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if
you must touch them, be sure to wear protective gloves.
WARNING
■ Tear apart and throw away plastic packaging bags so
that children will not play with them.
Children playing with plastic bags face danger of
death by suffocation.
■ Safely dispose of packing materials. Packing
materials, such as nails and other metal or wooden
parts, may cause stabs or other injuries.
CAUTION
■ Earth the heater kit.
Earthing resistance should be according to local laws
and regulations.
Be sure to establish an earth. Do not earth
the heater kit to a utility pipe, surge
absorber, or telephone earth. Incomplete
earth may cause electrical shock.
■ Gas pipe.
Ignition or explosion may occur if the gas leaks.
■ Water pipe.
Hard vinyl tubes are not effective earths.
■ Lightning conductor or telephone earth wire.
Electric potential may rise abnormally if struck by a
lightning bolt.
