Maintenance (Cont’d.)
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 impregnated with mild soap or antibacterial solution to remove any debris or residue accumulation.
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
contaminants.
The coil should also be inspected for evidence of leaks on the surfaces, connections to the coil tails, and all
externally 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
construction of the coils (copper tubes, aluminum fins).
• Compressed air may be used to blow through the coil fins, however care should be taken to ensure that any
residue, 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
• 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.
