Nameplates
There are several identification nameplates on the chiller:
• The unit nameplate is located on the exterior of the Unit
Control Panel. Both the Model No. and Serial No. are
located on the unit nameplate; the Serial No. is unique to
the unit. These numbers should be used to identify the unit
for service, parts, or warranty questions. This plate also has
the unit refrigerant charge and electrical ratings.
• Vessel nameplates are located on the evaporator and
condenser. They have a National Board Number (NB) and a
serial number, either of which identify the vessel (but not the
entire unit).
Receiving and Handling
The unit should be inspected immediately after receipt for
possible damage. All Daikin Applied centrifugal water chillers are
shipped FOB factory and all claims for handling and shipping
damage are the responsibility of the consignee.
On units with factory-installed insulation, the insulation is
removed from the vessel lifting hole (also used for transportation
tie-downs) locations and is shipped loose. It should be secured in
place after the unit is finally placed. Neoprene vibration isolation
pads are shipped loose in the power panel. If the unit is equipped
with a shipping skid, leave the skid in place until the unit is in its
final position. This will aid in handling the equipment.
CAUTION
Extreme care must be used when rigging the unit to prevent
damage to the control panels and refrigerant piping. See the
certified dimension drawings included in the job submittal for
the weights and center of gravity of the unit. If the drawings are
not available, consult the local Daikin Applied sales office for
assistance.
Location
WME chillers are intended only for installation in an indoor or
weather protected area consistent with the NEMA 1 rating on the
chiller, controls, and electrical panels, and not accessible to the
general public.
NOTICE
Indoor installations must be in a structure with a permanent floor
and roof. The unit must be enclosed by walls for protection from
weather conditions.
NOTICE
The maximum operating altitude for the WME-D is 3000m.
Consult a Daikin Applied application engineer for derating
schedule.
Excessive humidity in the mechanical room should be avoided. A
limit of 95% non-condensing humidity should be met to minimize
electrical components exposure to water condensing in panels.
Humidity levels in the mechanical room, even if lower than 95%,
can cause water to condense on/near all cool surfaces and
potentially lead to premature component wear. If possible, the
mechanical room should be conditioned which can extend the
useful lifetime for all mechanical room equipment.
NOTICE
Radiant heat from boilers or piping that would adversely raise
component surface temperatures beyond ambient limits must
also be avoided.
DANGER
Prevent lint, paper fibers, dust, metallic chips, or other foreign
material from getting into the inverter or accumulating on VFD
cooling outlets, the heat sink, circuit boards, control panels, or
other electrical devices. Failure to do so may affect operation
of the VFD, void warranty, result in a fire, unit damage, property
damage, severe personal injury, or death. Frequently inspect
area around inverter, heatsink, and other electrical devices to
ensure they are free of foreign material.
Clearance
The unit must be placed in an area that allows for adequate
clearance around the unit. See Figure 6 for clearance
requirements around the sides of the chiller. Doors and
removable wall sections can be utilized to meet these clearance
requirements. There must be a minimum 3-foot clearance above
the top of the chiller. The U.S. National Electrical Code
®
(NEC) or
local codes can require more clearance in and around electrical
components and must be checked for compliance.
Mounting
The unit must be mounted on a concrete or steel base. Make
sure that the floor or structural support is adequate to support the
full operating weight of the complete unit.
The neoprene vibration pads (shipped loose in the power panel)
should be placed under the corners of the unit (unless the job
specifications state otherwise). They must be installed so that
they are flush with the edges of the unit feet.
It is not necessary to bolt the unit to the mounting slab or
framework. Should this be required by local codes, 1-1/8 inch
(1.125 inch, 28.5 mm) mounting holes are provided in the unit
supports at the four corners. When mounted, the base pad of the
unit must be level to within ± 1/2 inch (0.5 inch,12.7 mm) across
the length and width of the unit.
