Coils - Trane CLCF Climate Changer Manual

Maintenance
Pulley alignment
Check using a straight edge along both pulleys (See Figure 24). It is recommended to use a metal ruler instead of
a string.
Correct position is showed on Figure 24.

Main coil
Pulleys are generally mounted with a conic joint.
Water entering/leaving connections
To remove pulleys, follow the manufacturer's directions.
Electric heater (accessory for blower only)
Pulleys not provided with a conic joint are mounted by forcing them onto the shaft.

Heating capacity
To remove them, heat the pulley hub and use a pulley extractor.

Belt replacement
G2 filter (filter box accessory)
To change the belt, the belt tensioning device is slackened off until the worn belt can be removed.

Before the replacement, clean the pulleys and check them for damage and wear.
G4 filter (filter box accessory)
Never use tools or force on the pulley edges as invisible damage can significantly reduce the life of these items. Quantity

If multi pulleys are in use all belts must be replaced simultaneously.

Check that the number of belts matches the number of pulley grooves.

roughly every 3 months and clean as necessary.
Heat exchanger operating limits:
Also check that the pipe work is watertight.
FWD:
*water temperature: max 100° C
Cleaning
*absolute service pressure: min 1 bar/max 11 bars
The cleaning is carried out with the coil in place using a powerful vacuum cleaner on the dust contaminated side.
Accessories - Hot water coil:
*water temperature: min. +2° C/max. 100° C
If the coil is very dirty it will need to be removed and wet cleaned. Zinc plated steel heat exchangers maybe cleaned
*absolute service pressure: min 1 bar/max 11 bars
with a steam jet or the fins washed through with a powerful water jet and finally blown out with pressurized air.
If required, soft cleaning brushes may be used ensuring that the heat exchanger fins are not damaged.
CAUTION! Coils with copper or aluminium fins are particularly vulnerable and must therefore only be cleaned with
a low pressure water jet. In case of specific clogging, call a cleaning specialist; Trane cannot be held responsible for
improper cleaning of the coils. Any damage to the fins by the use of undue force will result in premature failure of
the heater coil.
Any points corroded or rusted should be cleaned off and coated with a zinc-based protective paint.
