Spares & repairs
Before attempting to carry out any work on our units, all accompanying documentation
including warning labels on the unit must be referenced.
Should it be necessary to remove any component ensure that these are secured into
position once reinstalled. It is critical that after any maintenance work has been conducted
that all components removed/replaced be refitted correctly by a competent engineer.
Important
Before attempting to carry out any maintenance work, investigative or repair work on our
units, the unit MUST BE COMPLETELY ISOLATED
from its electrical supply. Ensure a minimum
of two minutes after electrical disconnection before removing access panels.

Care should be taken whilst cleaning the unit in the event that air movement should cause
the fan to freewheel.
Caution
Check inside the unit for an accumulation of dust, grease etc. If the fan impellor is heavily
soiled, clean out carefully, ensuring the unit is properly isolated. Failure to do this
periodically could lead to aloss of performance or the fan to become out of balance,
leading to bearing/fan failure.
Annual Checks
At the end of their useful life the packaging and product should be disposed of via a
suitable recycling centre. Do not dispose of with normal household waste. Do not burn.

Before operation, the following checks should be carried out:
Installation and electrical connection have been carried out as per the instructions in
this document and associated documents.
Safety equipment is in place, (terminal box cover overload protection, Isolators installed)
All leftover materials and other foreign materials have been removed from the fan cavity
before start up.
Earth has been connected
Temperature monitor/motor protection has been connected if required.
Cable gland is properly sealed.
Check for correct fan rotation direction of three phase fans as stated on the fan blade. If
the rotation is incorrect, interchange any two phases of the incoming supply at the
terminal block.
If these checks are carried out, and risk is assessed as being low, the unit can be switched on.
