Installation

Pre-installation Preparation
◆
Cargo inspection
All units are firmly bolted on wood trays, subject to ex-factory inspection and filled with accurate amount
of R410a refrigerant and refrigeration oil for the unit operation. Upon the receipt, you shall carefully
inspect cargoes for any damage during transport and confirm all ordered parts and accessories are
delivered.
You shall inform delivery man of any damage immediately. And you shall inform problem to us other than
appearance damage immediately.
◆
Handling
You shall handle the unit by a forklift or crane. If a
crane is used, the top and side panel of the unit
shall be protected by appropriate spacers (as
shown in the figure). During the handling, the unit
shall be kept horizontal and not be inclined for
more than 30°, and the unit damage due to
violations shall be avoided.
◆
Disassembly
Place the unit at a desired position, cut binding
tapes, remove the external crate, unscrew bolts
and remove the wood base from the unit bottom.
■
Selection Installation Position
For the better cooling (heating), the installation position of the chiller unit shall be selected as per the
followings:
◆
The unit shall be installed at a place where the hot air exhausted by the unit is not sucked back, that
exhausted by other unit is not sucked and sufficient space is reserved for the unit maintenance.
◆
Exhaust and suction channels of the chiller unit shall be free of any barrier that will block the air flow.
◆
The unit is installed at a well ventilated place to improve the heat exchange.
◆
The installation position shall have enough strength to withstand the unit weight and the vibration
during operation.
◆
The unit shall not be installed at a place that is dirty, oily, salty and exposed to a large amount of
sulfur gas.
◆
The chiller unit shall not be installed at such place where flammable gas may leak. Because the
flammable gas leaked and accumulated around the unit may lead to explosion.
◆
The chiller unit shall not be installed at such a place exposed to strong wind or typhoon or
accumulated rainwater and snow. If possible, auxiliary equipment for preventing rainwater, snow
and direct sunshine may be provided.
◆
The unit base shall be made of concrete or support. Full consideration must be given to floor
strength, drainage (water is drained from the unit during operation) and pipe and wire route in the
base construction. If the base is not strong enough, the unit may fall down, causing unit damage or
personal injury.
◆
The chiller unit shall be firmly fastened with anchor bolts to prevent falling down due to earthquake
or strong wind. In order to withstand strong wind and earthquake, the unit must be positioned
properly and can not be installed at such a place exposed to strong wind.
◆
Depending on installation conditions, vibration may be transferred to fitted parts, and base plates
and walls may produce vibration and noise. Therefore, proper vibration protections (e.g. setting
shock pad, dumper bracket, etc.) shall be provided.
◆
Edges and corners must be positioned correctly. The improper installation may lead to instability,
resulting in bending of mounting feet. Any improper installation may cause the falling down of the
unit, leading to personal injury.
