Service Clearances
In addition to providing adequate space around the unit for
piping coils and drains, access to at least one side of the unit
is always required to allow for regular service and routine
maintenance, which includes filter replacement, drain pan
inspection and cleaning, fan bearing lubrication, and belt
adjustment. Provide sufficient space—at least equal to the
length of the coil—on the side of the unit for shaft removal and
coil removal. Space, at least equal to the length of the side
coil, is required for coil removal. Space, at least equal to the
fin height, is required for top coil removal. See
servicing space requirements.
For routine maintenance purposes, access is normally
obtained through the access doors or by removing panels.
Fan and filter sections are always provided with a service door
on one side of the unit. If requested, doors can be provided
on both sides of the unit. Optional service doors are available
for most section types and are provided based on customer
request.
If component replacement is required, the top panel also
can be removed. If necessary, the unit can be disassembled.
Maintain 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 up to 12" deep. See
sections with multiple fans have motor control boxes up to 16"
deep when supplied with VFDs.
