■ 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.
■ The unit shall be positioned so as to minimize the impact on residences.
