INTRODUCTION

The purpose of this manual is to provide instructions which
supplement good general practices when installing or oper-
ating fans made by the CARNES CO.. It is the responsibili-
ty of the purchaser to provide qualified personnel experi-
enced in the installation, operation and maintenance of air
moving equipment.
Instructions given in the body of this manual are general in
nature and apply to a variety of models manufactured by
CARNES CO. Most units can be installed and maintained
with the instructions given.
Special applications may require additional information.
These instructions are supplied in the form of attached
appendices. Use the instructions in the appendix if the direc-
tions in the manual differs from instructions in the appendix.
As always, follow good safety practices when installing,
maintaining and operating your air moving equipment. A

SHIPPING AND RECEIVING

All CARNES CO. products are carefully constructed and
inspected before shipment to assure the highest standards
of quality and performance. When received, all components
should be compared to the bill of lading or packing list to
verify that the proper unit was received. Each unit should be
checked for any damage which may have occurred in tran-
sit. Any damage should be reported immediately to the car-
rier and the necessary damage report filed.

HANDLING

Handling of all air moving equipment should be conducted
by trained personnel and be consistent with safe handling
practice. Verify the lift capacity and operating condition of
handling equipment. Maintain handling equipment to avoid
serious personal injury.
Units shipped completely assembled may be lifted with
slings or spreader bars. Well-padded chains, cables or nylon
straps may also be used. On most units, lifting lugs are pro-
vided for attaching chains (see Figure 1). Lifting the fan
should always be done in such a fashion which protects the
fan and fan coating from damage. Never lift a fan by the inlet
or discharge flange, shafting or drives, wheel or impeller,
motor or motor base, or in any other manner which may
bend or distort parts.
Partial or disassembled units require special handling. All
parts should be handled in a fashion which protects the
coatings and parts from damage. Components should be
handled such that forces are not concentrated and bending
or distortion can not occur.
