Locating the Unit
Placement of the unit relative to ductwork,
electrical and plumbing must be carefully
considered. Return air plenum or duct can be
mounted directly to the return air flanges.
Use flexible gasket material to seal the duct
to the unit.
Verify floor, foundation or suspension
support can support the total unit weight,
including accessory weights. Unit must be
level in both horizontal axes to support the
unit and reduce noise and vibration from the
unit.
Allow adequate space for piping access and
panel removal. To ensure proper access
for field service, maintain minimum
clearances for field piping and other
obstructions as indicated by Table 1 and
Figure 2 and Figure 3. Consult local
building codes for additional service
clearance requirements. Condensate drain
connections are located on the access side of
the unit.

Floor Mounted Units
Make sure the unit is level and mounted on a
field supplied platform with a minimum
height to allow for proper depth of the
condensate line p-trap. Other installation
provisions may be necessary according to
job specifications. V3 Series vertical air
handling units are designed for upflow
applications only
