RECEIVING AND INSPECTION
All units are factory tested to ensure safe operation and
quality assembly. Units are packaged for easy handling and
storage at the job site. Upon delivery, inspect all compo-
nents for possible shipping damage or shortages. Record
torn or broken packaging and scratched or damaged pan-
els on the delivery receipt and report to the carrier imme-
diately. Report any damage or shortages discovered after
unpacking to the carrier in the allotted time after delivery.
Inspect the refrigerant circuits to confirm that no leaks
have occurred during the shipment. If there is no holding
charge in the unit, it is possible that the coil was damaged
during shipment. Pressure test the coil dry nitrogen to
confirm there are no leaks.
Take photos of all damaged equipment, if possible. Dam-
aged equipment is the responsibility of the designated
carrier. Do not return to the manufacturer unless prior
approval is given to do so. Confirm that all items listed on
the bill of lading are received, especially loose items such
as air throw streamers, inlet hoods, and fan guards.
NOTICE
Record any unit damage and shortages on the bill of
lading and report to the carrier and FRICK factory
immediately. Shipping and handling damages are not
warranty items.
Compare the data on the nameplate of the unit with the
ordering and shipping information to verify the correct unit
is received. Verify the model nomenclature and electrical
data with the original order.
The unit can be transported with a forklift, with the forks
extended completely underneath the skid in the center of
the unit. Do not allow the forks to make contact with the
unit. See Rigging instructions for greater detail.
The unit is intended for indoor use only. To protect the
unit from damage due to the elements, store the unit in
a clean, dry location and away from areas with exces-
sive traffic. The unit must remain on its skid, which is only
removed at the time of installation. Ventilate the unit well
at all times during storage.
NOTICE
Always ensure that there is no obstruction to the air
intake or discharge for every unit.
AIR COOLER LOCATION
• Never locate units directly above doorways. Locate units
as far away as possible from areas of high infiltration.
• The location of the units must allow for the air pattern
to cover the entire room.
• Ensure the distance of the air inlet side of the coil from the
wall is at least 0.8 x face height to prevent obstructed air-
flow patterns. The face height is the height of the evapo-
rator coil without the frame.
• Position the unit in relation to racks, aisles, lighting, and
the product so that air leaving the unit is not obstruct-
ed. The performance of the unit is determined by the
specified air quantity flowing across the coil, and the
inlet temperature of this air as stated in the submittal
documentation. If either of these are compromised, the
performance of the unit may be adversely affected.
• Do not connect the unit to ducting on either the air inlet
or air leaving side, unless it has been specifically engi-
neered to do so and all external pressures have been
accounted for.
• Position the unit in relation to the compressor room to
minimize pipe runs.
• Position the unit to minimize condensate line runs.
• The size, shape, and specific location of the room deter-
mines the number and type of units to use.
• Ensure sufficient access at the sides, back, underneath,
and front of the unit is available for maintenance work
to be undertaken. A minimum of 3 ft (1 m) is generally
sufficient at the sides and in front of the unit. The 0.8 x
face height must be the minimum distance at the back
of the unit on the air inlet side. Bottom clearance for the
removal of the pan must be the width of the unit at a
minimum.
• Units with electric defrost require an access area the
same length as the side of the unit from which the elec-
trical elements are being removed. This is the refriger-
ant connection end of the unit.
• Ensuring optimum performance of the unit with unob-
structed airflow is the responsibility of the installing
contractor.
AIR COOLER MOUNTING
Most units can be mounted with threaded rod or bolts
suspended from the steel or ceiling structure above the
unit. Take care to ensure that the unit is mounted level so
that condensate drains properly. The steel or ceiling struc-
ture must be strong enough to support the unit. All the
mounting holes in the hangers on the unit must be used
for supporting the unit. In some instances, for example
seismic, the installing contractor might require additional
bracing. Mount foot mount units on the floor or steel
structure, either bolting or welding them to the support
structure. Ensure that the support structure is level.
NOTICE
Never position air coolers directly above doors or door
openings.
Ensure that a space equal to 0.8 x unit height between
the wall and air inlet side is maintained.
Always allow for a space equal to the unit height below
the unit.
Do not stack product directly in front of the unit.
