Plastec 50 User Manual

INTRODUCTION

DO NOT INSTALL, USE OR OPERATE THIS EQUIPMENT UNTIL
THIS MANUAL HAS BEEN READ AND UNDERSTOOD.

The installer assumes ultimate responsibility for ensuring that
current installation regulations are fully observed and that the
exhaust fan receives adequate protection from adverse electrical,
mechanical, thermal or environmental conditions.

The fan must be regularly inspected and maintained by qualied

staff in order to avoid damage and accidents. Material damage
and personal injuries can result from improper service.

Fan must not be installed near working or common areas. The
fan must always be installed in such a way that rotating parts
cannot be touched.

Products must be stored in a clean dry place protected from

temperature uctuations. If it is necessary to store equipment

outdoors, protect from the elements as much as possible. Keep
equipment dry and clean.

Please, carefully follow the instructions set out below.

1. INSTALLATION

WARNING! Before installation begins check for and clear any foreign materials in

the Fan/Blower and other components to be attached to the Fan/Blower.

CAUTION! Before installation check that all locking screws and nuts and bolts are

tightened properly, including the motor screws/nuts.

DANGER! Check the electrical connections and wiring.

Fan should be connected to ductwork with Flexible PVC Reducer/Couplings to avoid
air leaks and to help in vibration isolation and noise reduction.

If Exhaust Stacks are to be mounted to the Fan/Blower, they must be supported to

avoid placing too much weight on the Blower, which could cause damage.

CAUTION! Avoid continuous air stream temperature use higher than 140ºF/60ºC.

Make sure the Fan/Blower Assembly is securely attached to a rm foundation at the

mounting location to prevent vibration and movement.

WARNING! The PLASTEC 50 Model Impeller rotates (spins) only in a Counterclock-

wise Direction (CCW). Never reverse the direction of the housing to Clockwise (CW)
to prevent poor performance and possible damage. The certied performance for
the PLASTEC 50 Model is for the correct orientation/direction of impeller rotation

as outlined.
