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.
