MAINTENANCE
General
Outdoor units do not require a planned prevenative
maintenance program under normal operating conditions, but
not less than once each cooling season, it is recommended
that the unit be inspected and, if necessary, cleaned.
Particular attention should be given to the air inlet side of the
outdoor coil to insure that leaves, grass, etc., are not being
drawn into the unit. Restriction to air flow across the coil will
result in loss of system capacity, high operating pressures
and excessive operating costs. If the outdoor unit is installed
adjacent to a grassy area, it is suggested that lawn mowers
be routed in such a manner that the discharge of the mower
will be directed away from the unit. There must be air filters
installed in the system at some point upstream to the indoor
coil. Air filters should be inspected and, if necessary, replaced
and/or cleaned AT LEAST once a month
