Standard features

STRUCTURE

All F&C units are built with heavy gauge corrosion resistant galvanized steel. All units are approved for installation

with “0” clearance to combustible materia

MOTORS

Standard motors are PSC, permanently lubricated type with internal thermal overload protection.

PLENUM

Return air plenums are manufactured from galvanized steel insulated with high-density anti-bacterial and anti-acus-

tic foam.

CONDENSATE PANS

Positive sloped drain pans are galvanized steel, coated on the inside surface with anti-bacterial and anti- fungal

coating.

COIL

Constructed with seamless copper tubes and headers. The tubes are mechanically expanded into corrugated alu-

minum fin material for a permanent primary to secondary surface bond. Coils are tested under water at 350 PSI for

operation at 300 PSI. Coils include manual air vent

FAN WHEELS

Are double width, double inlet (DWDI) forward curved, centrifugal type. Wheels are statically and dynamically ba-

lanced for smooth, quite operation. The housing is constructed from heavy gauge galvanized steel with die-formed

inlet cones.

MOTORS

Motors are PSC, permanently lubricated type with internal thermal overload protection.

CLIFC FIXED - INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Maintenance warnings

Before attempting to perform any maintenance work whatsoever on the equipment, it is essential

that the equipment is disconnected and completely isolated from the mains power suppl

After disconnection of the mains power supply, a minimum of 1 minute should be allowed for any

rotating parts to come to rest before access panels are removed. However, care should still be

taken as it is possible for airflow generated in other parts of the system to cause the fan impellor

to rotate (windmill effect) even when power is not present.

Access panels are not fitted with restraints.

Appropriate PPE should be worn and correct tools should be used when undertaking these various

maintenance tasks.

Access panels that are removed for maintenance operations should be placed at floor level in a

safe location until they are ready to be re-fitted. Replace access panels at the same locations and

in the same orientation as found, and ensure that the screw fixings are fastened securely, but not

over-tightened.

If failure of the equipment occurs or is suspected, then it should be taken out of service until the

appropriate maintenance or repair can be undertaken.

Maintenance

FILTERS

Filters must be properly maintained in order to ensure proper air cleaning efficiency and to maintain design

airflow. Acoustic output may also be adversely affected by dirty filter.

The length of time between cleaning of filters is dependent upon the air condition. A three month cycle is normal,

however more frequent maintenance may be required in some cases.There is one air filter fitted to the equipment

in the inlet air path, upstream of the heat exchange coil. The filter may be slid out to either side of the unit. Alterna-

tively, the crosshead screws which fix the filter retaining angle to the equipment body may be loosened to provide

sufficient clearance for the filters to be manoeuvred out of their retaining channels. Where the equipment includes

for the filter to be fitted within a separate in-board filter section,remove the screws securing the access panel and

remove the filter. Initially, cleaning can be performed by gently tapping and removing loose dust with an air line or

vacuum cleaner.

Once removed, washable filters may be fully immersed in warm water with a mild detergent solution. Agitate the

water until all contaminants have been removed. The filter should then be rinsed in clear water, allowed to drain

and air dried before replacement. In the event of heavy soiling or damage to the filter media or wire support frame,

the entire filter should be changed. When refitting new filters into the equipment, it is important to ensure these are

fitted correctly in respect of airflow. The correct orientation is obtained when the wire frame is positioned towards

the heat exchanger, and the filter media completely covers the wire frame
