KHF - SERIES A FAN COIL UNITS
INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
UNPACKING & INSPECTION
All units are carefully inspected at the factory throughout
the manufacturing process under a strict detailed quality
assurance program, and where possible, all major
components and subassemblies are carefully tested for
proper operation and verified to be in full compliance with
the factory manufacturing documents. Customer furnished
components such as control valves, switches and DDC
controls are not factory tested.
Each unit is carefully packaged for shipment to avoid damage
during normal transport and handling. The equipment should
always be stored in a dry place in the proper orientation as
marked on the carton.
All shipments are made F.O.B. factory and it is the
responsibility of the receiving party to inspect the equipment
upon arrival. Any obvious damage to the carton and/or its
contents should be recorded on the bill of lading and a claim
should be filed with the freight carrier.
After determining the condition of the carton exterior,
carefully remove each unit from the carton and inspect
for hidden damage. At this time check to make sure that
“furnished only” items such as switches, thermostats, etc.,
are accounted for. Any hidden damage should be recorded
and immediately reported to the carrier and a claim must
be filed. In the event a claim for shipping damage is filed,
the unit, shipping carton, and all packing must be retained
for physical inspection by the freight carrier. All equipment
should be stored in the factory shipping carton with internal
packing in place until installation.
At the time of receipt, the equipment type and arrangement
should be verified against the order documents. Should
any discrepancy be found, the local Sales Representative
should be notified immediately so that the proper action
may be instituted. Should any question arise concerning
warranty repairs, the factory must be notified BEFORE any
corrective action is taken. Where local repairs or alterations
can be accomplished, the factory must be fully informed
as to the extent and expected cost of those repairs before
work is begun. Where factory operations are required,
the factory must be contacted for authorization to return
equipment and a Return Authorization Number will be
issued. Unauthorized return shipments of equipment and
shipments not marked with an authorization number will be
refused. In addition, the manufacturer will not accept any
claims for unauthorized expenses.
CODE COMPLIANCE
This equipment has been manufactured and certified in
accordance with UL 1995-Standard for Safety, Heating and
Cooling Equipment (CAN/CSA C22.2 NO 236- M90) and bears
the Electrical Testing Laboratories (ETL) Mark under ETL File
No.: 3036742-002.
HANDLING & INSTALLATION
While all equipment is designed for durability and fabricated
for sturdy construction and may present a rugged
appearance, great care must be taken to assure that no
force or pressure be applied to the coil, piping or drain stub-
outs during handling. Also, depending on the options and
accessories, some units could contain delicate components
that may be damaged by improper handling. Wherever
possible, all units should be maintained in an upright
position and handled by the chassis as close as possible to
the mounting point locations.
In the case of a full cabinet unit, the unit must obviously be
handled by the exterior casing. This is acceptable providing
the unit is again maintained in an upright position and
no impact forces are applied that may damage internal
components, access panels, or painted surfaces. The
equipment covered in this manual IS NOT suitable for
outdoor installations. The equipment should never be
stored or installed where it may be subjected to a hostile
environment such as rain, snow, or extreme temperatures.
During and after installation, special care must be taken to
prevent foreign material such as paint, plaster, and drywall
dust from being deposited in the drain pan or on the motor
or blower wheels. Failure to do so may have serious adverse
effects on unit operation and in the case of the motor and
blower assembly, may result in immediate or premature
failure. All manufacturers’ warranties are void if foreign
material is allowed to be deposited on the motor or blower
wheels of any unit. Some units and/or job conditions
may require some form of temporary covering during
construction.
While the manufacturer does not become involved in the
design and selection of support methods and components,
it should be noted that unacceptable system operating
characteristics and/or performance may result from
improper or inadequate unit structural support. In addition,
adequate clearance must be provided for service and
removal of the equipment and its accessory components.
Anchoring the equipment in place is accomplished by using
the mounting points provided and positioning the unit
to maintain the unit on a LEVEL plane. The drain pan is
internally sloped toward the outlet connection. Care must
be taken to insure that the unit drain pan does not slope
away from the outlet connection. All units are supplied with
integrated hanger brackets with optional grommet isolators
and brass inserts for use with 3/8” all thread hanger rod.
The unit’s drain pan is factory sloped toward the
unit’s drain pan drain connection when the unit is
installed level and plumb.
