Indoor Condensers
Smaller air-cooled units (2.5 to 5-ton) are available with either an indoor condenser section or an outdoor
condenser. While most air-cooled units have outdoor condensers, indoor condensers are occasionally used. The
indoor condenser sections are to be mounted in a similar manner as the evaporator sections. Indoor air-cooled
condensers have factory provided duct collars on the supply and intake air openings as appropriate to allow
connection of the field supplied duct systems.
Typical installations have the indoor or outdoor condenser near or adjacent to the evaporator section especially
when shared electrical power is required. The same service and maintenance requirements apply to these units as
well.
Storage
NOTICE (Important)
This storage section is not intended to be a comprehensive
guide for all possible issues associated with construction conditions,
construction stage, and indoor environment, how interior spaces are
maintained and other factors affecting the equipment storage. Each installation
is unique.
Short-term storage is considered 60 days or less from shipment date. Long-term storage is considered any period
beyond 60 days from date of shipment. It is mandatory that a detailed record be maintained during this long-term
period, such as, but not limited to: proper sealing of the cabinet, rotation of the blowers and bearings, and
protection of all motors from moisture. Check the fan rotation monthly, the fan and motor should be rotated several
times to replenish the bearing surfaces with fresh grease as needed and to prevent flat spots of the fan shaft. The
fan impeller should be left at approximately 180° from that of the previous month to prevent the belts from taking
a set position.
