This unit requires minimal maintenance to operate
properly. Maintenance requirements for this model vary
for each installation and depend greatly on how much
the system is used and the cleanliness of the air.
Proper maintenance will both increase the life of the
system and maintain its efficiency. Maintenance must be
performed by experienced technicians and in the case of
refrigeration systems, must be done by an EPA certified
technician.
Maintenance frequency is based on a presumed
nominal use of the system. If the system is being run
constantly, the frequency should be adjusted
accordingly. If there is seasonal debris in the air which
can be drawn into the filters and the coils, they should
be checked more frequently. If the system is being used
for only a few hours per day, the frequency may be
reduced. Use the maintenance log at the end of this
manual to record each maintenance session and
observations and then establish a maintenance
schedule that is appropriate for the installation. The
following is provided as a guideline.
Maintenance Frequency:
Monthly
1. External Filter
Clean Aluminum mesh filters
2. Internal Filters
