Maintenance

Generally to be carried out every 12 months.

Service

Each unit should be inspected for mechanical & electrical defects. Installation

of the fan motors and associated wiring should be tested.

Cleaning

Dirt and dust should be brushed free from the motor, grille and impellers , to

ensure proper operation of the unit. Grilles and impellers may be cleaned with

soapy water and a soft cloth.

Lubrication

All motors have sealed for life bearings and do not require attention.

The motors supplied on the King units are capable of being wired for single

and three phase with small modifications.

Normally, however they will be supplied to specification as either single or

three phase. Motors are also suitable for clockwise and anticlockwise rotation.

However, the units are supplied with impellers for specified rotational direction

and it is important the wiring is matched to the impeller rotation (see Fig.5)

Fig 5. - Single Phase

Terminals are pillar type with 7mm nuts. It is therefore recommended that the

wiring connections are made using 2 or 4BA crimp spade or eyelet terminals.
