RECEIVING
When the absorption chiller is delivered to
the job site, inspect for any transit damage. Report
any damage to the carrier and note on the bill of
lading. Notify the Yazaki Sales Representative or
Distributor before proceeding with the installation
of a damaged unit.
UNIT NAMEPLATE
The UNIT NAMEPLATE is located on the
lower right hand side of the front panel on each
absorption chiller unit. Check that the model
number, flow rates and electrical specifications
are compatible with the system design and
services available.
RIGGING
Remove the crate from the absorption chiller.
When access is restricted, it may be necessary to
remove the skid to reduce overall height.
Each unit has four eye bolts in the top panel
which should be used for lifting.
Care should be taken at all times during
rigging and handling of the absorption chiller to
avoid damage to the panels and external pipe
connections. DO NOT DROP.
Attach a sling to the four eye bolts in the top
panel as shown in Fig.1 and ensure that the rope
angle is greater than 60
O
to the horizontal plane.
Always carry the absorption chiller in a NEAR
VERTICAL POSITION. DO NOT TIP OVER.
The dry weight and overall dimensions are
shown in PHYSICAL DATA on Page 3 as a guide
for rigging (add 6 in. to overall height for skid).
When moving the absorption chiller, check
that the route is accessible. The minimum access
dimensions for a skid mounted chiller are shown
in Fig.2.
LOCATION
Yazaki absorption chillers have a weather-
proof cabinet suitable for either indoor or outdoor
installation.
Select a location with due consideration for
the proximity of the cooling tower, chilled/hot
water coils and service access.
The minimum space requirements, shown in
Fig.3, must be provided around and above each
chiller for installation and service access.

Fig. 2 ACCESS CLEARANCES (IN.)
The roof on which equipment is to be
installed shall be capable of supporting the
operating weight of the absorption chiller,
associated pumps, cooling tower and piping.
Install the equipment on a well drained surface of
the roof at least 6 ft. from the edge. If the roof is
poorly drained at the equipment or in the
passageway to the equipment a suitable platform
of walkway should be provided adjacent to the
equipment and control panels so that it can be
serviced safely.
