Installation Guidelines
Service Clearances
Leave adequate space around the unit for piping, coils, and
drains. Always have access to at least one side of the unit for
regular service and maintenance. See Figure 2 for servicing
space requirements. Routine maintenance examples include
filter replacement, drain pan inspection and cleaning, fan
bearing lubrication, and belt adjustment. Provide sufficient
space on the drive side of the fan and the connection side of
the coil for shaft and coil removal, if necessary (refer to the
“Coil Data” section in Catalog 580 for information about coil
sizes). Both the fan drive and coil can be field modified to
right or left hand to accommodate clearance restrictions. See
“Reversing the Coil Handing” on page 9 and “Reversing the
Drive Package” on page 11.
For routine maintenance, remove panels on either side of the
unit. See “Panel Removal” on page 8. Optional service doors
are available for the fan and filter sections. Allow sufficient
space for service door(s) to swing completely open, or to meet
the clearance requirement of the section it accesses, whichever
is greater. Service doors are not interchangeable with access
panels on the opposite side of the unit. Determine clearances
before specifying doors.
Have at least 54" of clearance in front of electrical power
devices (starters, VFDs, disconnect switches, and combination
devices). Electrical power devices that are mounted on the side
of the unit typically are 12" deep (see Figure 2).
