INTRODUCTION

This manual is to assist the engineer to avoid the most common fan problems caused by

improper storage, installation, operation and maintenance. HANDLING AND MAINTENANCE

SHOULD ALWAYS BE PERFORMED BY EXPERIENCED AND TRAINED PERSONNEL.

RECEIVING, HANDLING AND STORAGE

Rough handling during shipment and improper storage can cause damage that is not noticeable

until the fan is in operation. This can be avoided with proper storage and handling techniques.

Fan should be hoisted with slings placed around the fan housing. Touch up the scratch coated

surfaces during lifting, to prevent corrosion to occur at this area. Store the fan in a clean and

dry place, preferably indoor to ensure fan shaft, bearing and fan casing are protected against

dust and corrosion. Do not store the fan in a location where it will be subjected to vibration.

This can cause the internal surface to rub against each other and damage the bearings.

INSTALLATION

 Ensure that suitable fastener is used for each of the mounting holes in the panel.

 Ensure that the fan panel and drive components are not bent or twisted during installation.

 Fan should be installed so that any obstructions will not be within 1 Diameter of the fan inlet

and outlet.

 Ensure that the fan orientation is correct for the required air flow direction.
