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

CONDENSATE DRIP TRAYS AND DRAINS
Drain lines should be checked to ensure that they are unobstructed and free draining.
Drain traps should be checked that they are fully primed and functioning correctly.
Drain trays should be checked to ensure they are free from debris. They should be periodically flushed out and
chemically treated as necessary to remove any contamination or debris.
To clean the drain tray, proceed as follows:
1. Disconnect the condensate drain pipework from the drain tray connection
2. Use a moist cloth impreganated with mild soap or antibacterial solution to remove any debris or residue accu-
mulation.
3. Make sure that there are no obstructions or debris in the pipework.
4. Reconnect the pipework to the drain tray connection.
WATER TO AIR HEAT EXCHANGE COIL
The finned surfaces of the heat exchange coil should be inspected for accumulation of dirt, dust, biological contam-
inants.
The coil should also be inspected for evidence of leaks on the surfaces, connections to the coil tails, and all exter-
nally visible copper tubes, headers and return bends.To inspect both faces of the coil, the fan access panels and
air filter should be removed.
Maintenance is performed as follows:
Superficial dust or debris can be removed from the surface by gently brushing with a soft long haired brush. Debris
can then be vacuumed from the surfaces and other areas.
Remove stubborn deposits or biological contaminants by careful application of a damp cloth. The cloth should be
dampened using warm water mixed with a mild detergent solution compatible with the materials used in the con-
struction of the coils (copper tubes, aluminium fins).
Compressed air may be used to blow through the coil fins, however care should be taken to ensure that any resi-
due, debris or water from washing does not contaminate the fan assemblies or electrical connections within the fan
chamber.
Residual water should be dried immediately with a cloth, and must not be allowed to saturate the insulation inside
the equipment casing.
If there is any evidence of leaks, the coil block should be removed, and either repaired or replaced.
Any treated water within the coil fluid circulation system should not be drained into any waste water disposal system
without Local Authority approval. It is the responsibility of the user and the maintenance personnel to ensure that all
Local Authority and prevailing environmental legislation / guidelines are adhered to.
Maintenance

CLIMA-FLEX 17
CLIFC FIXED - INSTALLATION, OPERATION AND MAINTENANCE MANUAL
Maintenance (Cont’d.)
FANS
Inspection of the fan assemblies (comprising the impellor and the motor) should be undertaken to ascertain whether
any overheating of the motor is occurring, and to check that the fan impeller is free running and has not sustained
any damage.
The fan assembly should be cleaned regularly, as any excessive build-up of dust or debris may cause the impellor
to fall out of balance, or the motor to overheat.
The impellor and motor should only be cleaned with a soft dry brush to remove dust deposits.
The fixings holding the fan motor to the fan scroll should be checked and tightened if necessary. In addition, the
fixing screws holding the fan scroll to the main body of the equipment should also be checked and tightened as
required.
These fixings must be secure before checking the fan bearings. Standard fan bearings are “sealed for life”, there-
fore no specific maintenance is possible. In normal service, the fans have an anticipated life of 40,000 hours.
However, the condition of the bearings should bechecked and assessed at regular intervals as follows:
The fan impellor should be rotated manually to detect any roughness or flat spots in the bearings. Gentle lateral
pressure should be applied back and forth on the impellor to detect any excessive movement or play in the bear-
ings. If any roughness, flat spots or excessive movement is found, then the fans should be replaced.
INTERNAL AND EXTERNAL SURFACES
All nuts, bolts and fixings should be checked for tightness.
The general condition of all components and the equipment overall should be checked.
The steel internal and external surfaces of the equipment should be regularly checked for scratches, corrosion, or
for peeling of painted surfaces.
If found, thoroughly clean affected areas with a wire brush, apply a coat of zinc rich primer or similar, and re-touch
with suitable finishing paint.
The insulating materials should be checked for condition and security. If the insulation shows signs of powdering
then it must be replaced. Insulation which is loose or peeling off should be made secure.
To replace insulation, proceed as follows:
1. Ensure that sufficient new insulation material with Class “O” fire resistance is available.
2. Peel off the existing affected insulation from the equipment casing.
3. Remove any old glue residues or residual foam.
4. Clean the area using suitable solvent cleaner such as ISO Propyl alcohol.
5. Position ETL / UL rated glue on the equipment casing, and press the new insulation into place. Let it cure and
dry..
IMPORTANT: ETL / UL rated glue MUST be used for the unit to maintain its ETL rating.

Maintenance (Cont’d.)
CONTROLS, PCBS AND WIRIN
The controls and electrical connections should be checked regularly.
The mains power supply connection should be visually checked. If there is any evidence whatsoever of damage or
deterioration of the power supply connection, then the unit must not be put back into service until the supply con-
nection has been replaced by suitably qualified personnel.
The condition of the controls devices, terminals, PCB and any associated wiring should be checked by visual in-
spection.
Any signs of discolouration, arcing or charring of any component, wire or terminal block should be investigated
immediately, and the equipment must not be returned to service until the problem has been found and rectified.
PCBs incorporate fusible links which protect certain components. In the event of a blown fuse, only new fuses of
equivalent specification, size and rating must be used.
The correct fuse ratings are permanently shown on the PCB. If fuses are blowing persistently, this condition must
be investigated immediately, and the equipment must not be returned to service until the problem has been found
and rectified
