DHK & DHK-NW
Centrifugal Fiberglass Fan
INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Introduction
This bulletin contains the proper installation, operation and
maintenance procedures for the standard DHK & DHK-NW
Medium to High Pressure Centrifugal Fiberglass Fan, to
ensure safe and trouble-free fan operation.
The M.K. Plastics catalog on the above corrosion resistant
FRP fan, provides additional information describing the
equipment, fan performance, available accessories, and
specifications.
For additional safety information, refer to AMCA publication
410-96, Safety Practices for Users and Installers of Industrial
and Commercial Fans.
For Information on special fan application requirements,
contact M.K. Plastics corporate office at (514) 871-9999.
Receiving and Inspection
All M.K. Plastics fans are carefully inspected before leaving
the factory. Compare all components with the bill of lading or
packing list to verify that the proper unit was received. Check
each unit for any damage that may have occurred in transit.
Mishandled units can void the warranty provisions. If units
are damaged in transit, it is the responsibility of the receiver
to make all claims against the carrier. M.K. Plastics is not
responsible for damages incurred during shipment.
WARNING
This unit has rotating parts. Safety precautions
should be exercised at all times during installation,
operation, and maintenance.
ALWAYS disconnect power prior to working on fan.
Handling
Fans are to be hoisted and moved by the lifting lugs provided
on the fan (see Figure 1). Location of lugs & brackets varies
by fan size and arrangement. Fans can also be hoisted with
slings placed around the fan housing. When a single hoist
is used, a “spreader” will keep the sling from slipping on the
housing. Large units may have lifting lugs or holes which
should be used only to stabilize the unit while using a sling to
support the weight.
Chain or wire slings should be well-padded where they
contact the fan as not to cause damage to the fiberglass
surface. Fans should never be lifted by the shaft, fan
housing, motor, belt guard, damper, weather hood, inlet &
outlet flanges or any other accessories.
Storage
If the unit cannot be installed and operated immediately,
precautions need to be taken to prevent deterioration of the
unit during storage. The user assumes responsibility of the
fan and accessories while in storage. M.K. Plastics will not be
responsible for damage during storage.
Store in a dry, protected area being sure fan shaft, bearings
and impeller are protected against dust and corrosion. If it
is necessary to store outdoors or within a building under
construction, special care must be taken to prevent moisture,
dirt or dust accumulation. Coat the shaft with grease or rust
preventative compound. Cover and seal bearings to prevent
entrance of contaminants. Impeller should be rotated at least
once a month to circulate the grease in bearings. If stored
outdoors, cover completely with a tarp or heavy plastic wrap.
Electrical connections and leads must be protected from
moisture. Block impeller to prevent natural rotation. Do not
allow material of any kind to be piled on top or inside of fan.
