■
Do not allow water to remain in the water piping during
prolonged idle periods.
For prolonged idle periods you should fill the water
pipes with antifreeze or drain all the water from the pipes. Failure
to do so could result in leaking.
■
Do not climb or place objects on top of the unit.
Falling or overturning could result in injury.
■
Make sure the unit base is not damaged by prolonged
use.
If damage is not repaired, the unit could fall and result
in injury.
■
Do not wash the unit with water.
Doing so could result in electrical shock.
■
Use chilled (hot) water and condenser water that
conforms to water quality specifications.
Poor quality water could result in water leaks.
■
Never touch parts which tend to become hot such as
compressors and refrigerant piping.
Doing so could result in skin burning.
Precautions when relocating or repairing the unit
WARNING
■
For repairs, be sure to contact your dealer.
Improper repair could result in electrical shock or fire.
■
Do not modify the unit in any way.
Doing so could result in electrical shock or fire.
■
To relocate the unit, be sure to contact your dealer.
Improper installation could result in electrical shock or
fire.
CAUTION
■
Pay attention to ventilation when repairing indoors.
If refrigerant leaks and the room is not sufficiently
ventilated, it could result in accidents caused by lack of
oxygen.

Inspecting the unit
At delivery, the unit should be checked and any damage should be
reported immediately to the carrier claims agent.
The unit comes with 6 rubber vibration isolator pads and 6 metal anti
vibration supports.
Lifting the unit
■
Refer to the diagram above. Have the lifting beam (1) and 4 wire
ropes prepared (2). Make sure that wire ropes are longer than
5 m. Be sure to lift the unit horizontally levelled.
■
The unit is shipped with transport stays under it. These have to
be removed before installation.
Pay special attention not to damage the lower collector (3) under
the condenser when removing the transport stays.
■
The condenser and evaporator have lifting holes (Ø50) at both
sides. Use these holes for lifting (4).
■
Perform lifting and transfer the unit slowly avoiding brusque
movements.
The unit is shipped from factory with refrigerant charged.
Brusque movement may result in unexpected behavior of the
product due to inertia force of the liquid refrigerant.
■
Select and use equipment for lifting, including the lifting
beam (1), with a sufficient safety factor. Take offset load into
account that can develop when the product inclines while lifting.
■
For preventing any external damage to the product, we request
you to protect the product by using protection patches (5) where
appropriate.
■
Make sure to first put the 6 metal anti vibration supports (6) and
6 rubber vibration isolation pads (7) in place on the
foundation (8) before putting the unit in its final position. Refer to
"Sound insulation and vibration isolation work" on page 7
Table 1
Before lifting, check the lifting weight stated in the delivery
specification again.
