Maintenance
1. Normal maintenance on all conditioners is generally limited to filter changes. Lubrication of the fan motor is not
required.
2. Filter changes are required at regular intervals. The time period between changes will depend upon the project
requirements. Some applications such as motels produce a lot of lint from carpeting and linen changes. It is
suggested that the filter be checked at 60-day intervals for the first year until experience is acquired. If light cannot
be seen through the filter when held up to sunlight or a bright light, it should be changed. A more critical standard
may be desirable.
3. The condensate drain pan should be checked annually and cleaned and flushed as required.
4. Records of performance measurements of volts, amps, and water temperature differences (both heating and
cooling) are recommended. A comparison of logged data with start-up and other annual data is useful as an
indicator of general equipment condition.
5. Periodic lockouts always are caused by air or water problems. The lockout (shutdown) of the conditioner is a
normal protective result. Check for dirt in the water system, water flow rates, water temperatures, airflow rates
(may be dirty filter), and air temperatures. If the lockout occurs in the morning following a return from night
setback, entering air below machine limits may be the cause.
