Installation and Startup
Installation and Startup
Installation and maintenance are to be performed only by
qualified personnel who are familiar with local codes and
regulations, and experienced with this type of equipment.
WARNING
Sharp edges and coil surfaces are a potential injury hazard.
Avoid contact with them.
Start-up by the Service Group of Daikin Applied is included
on all Pathfinder units sold for installation within the U.S. and
Canada and must be performed by them to initiate the standard
Limited Product Warranty. Start-up by any party other than
the Service Group of Daikin Applied or a Daikin Applied
Authorized Service Representative will void the Limited
Product Warranty. Two-week prior notification of start-up is
required. The contractor should obtain a copy of the Start-up
Scheduled Request Form from the sales representative or
from the nearest Daikin Applied Service office.
WARNING
Escaping refrigerant can displace air and cause suffocation.
Immediately evacuate and ventilate the equipment area. If the
unit is damaged, follow Environmental Protection Agency
(EPA) requirements. Do not expose sparks, arcing equipment,
open flame or other ignition source to the refrigerant.
Handling
DANGER
Improper lifting or moving of a unit can result in property
damage, severe personal injury or death. Follow rigging and
moving instructions carefully.
Avoid rough handling shock due to impact or dropping the
unit. Do not push or pull the unit. Never allow any part of the
unit to fall during unloading or moving, as this can result in
serious damage.
To lift the unit, lifting tabs with 3" (76 mm) diameter holes are
provide
d on the base of the unit. All lifting holes must be used
when lifting the unit. Spreader bars and cables should be
arranged to prevent damage to the condenser coils or unit
cabinet (see Figure 2).
Location
Locate the unit outdoors and carefully to provide proper
airflow to the condenser
.
(See Figure 3, page 5 for required
clearances.)Using less clearance than s
hown in Figure 3can
cause discharge air recirculation
to the condenser and could
have a significant detrimental effect on unit performance.
Due to the shape of the condenser coils on the
Pathfinder
chillers, it is recommended that the unit be oriented so that
prevailing winds blow parallel to the unit length, thus
minimizing the wind effect on condensing pressure and
performance. If low ambient temperature operation is
expected, optional louvers should be installed if the unit has no
protection against prevailing winds.
For pad-mounted units, it is recommended that the unit be
rai
s
ed a few inches with suitable supports such as neoprene
waffle vibration pads, located at least under the mounting
locations. This will allow water to drain from under the unit
and facilitate cleaning under it.
Figure 2: Required Lifting Method
NOTES:
1. Unit with 8 lifting points illustrated above; the number of
condenser sections, fans, and lifting points can vary from
this diagram.see lifting/mounting drawings beginning on
page page 20 to identfy the number of lifting points for a
specific unit.
2. All rigging points must be used. See weights at lifting
points beginning on page 15 for each specific size unit.
3. Crosswise and lengthwise spreader bars must be used to
avoid damage to unit.
Mounting Hole Access
The inside of the base rail is open to allow access
for securing
mounting bolts, etc.
Service Access
Compressors, filter-driers, and manual liquid line shutoff
valves are accessible on each side
or end of
the unit. The
evaporator heater is located on the barrel.
The control panels are located on the end of the chiller. The
left-hand con
trol box contains the unit and circuit
microprocessors as well as transformers, fuses and terminal.
