Carrier 40UV - Identify and Prepare Units; Physical Data; Installation; Placing Vertical Units in Position

2
Identify and Prepare Units
1. Be sure power requirements match available power
source. Refer to the unit nameplate and wiring diagram.
2. Remove front (40UV) or bottom (40UH) access panels
from the unit. Retain the
5
/
32
-in. socket head fasteners and
panels for reinstallation later.
3. Rotate the fan shaft by hand to ensure that fans are
unrestricted and can rotate freely. Check for shipping
damage and fan obstructions.
PHYSICAL DATA
Component weight data of 40UV,UH units is provided in
Table 1.
INSTALLATION
Placing Vertical Units in Position
1. Select the unit location; ensure that service clearance is
provided. Allow enough grille clearance to maintain
unrestricted airflow. See submittal drawings and Fig. 1
and 2 for dimensions.
2. Make sure wall behind unit is smooth and plumb; if
necessary, install furring strips on walls with irregular
surfaces or mullions. Furring strips must be positioned
behind mounting holes in unit. Fasteners, furring strips,
and other seals (if required) must be field supplied.
3. Remove all wall and floor moldings from behind the unit.
4. Move unit into position. Unit must be snug against wall
and furring strips.
5. Adjust unit leveling legs so unit is level. Unit must be
level for proper operation and condensate drainage.
6. Using field-supplied fasteners, reach into unit and attach
unit to the wall using the
3
/
4
in. mounting holes in the
back panel.
7. Protect the unit from jobsite debris. Do not allow foreign
material to fall into drain pan. Prevent dust and debris
from being deposited on motor or fan.
Placing Horizontal Units in Position
1. Select the unit location; ensure that service clearance is
provided. Allow enough grille clearance to maintain unre-
stricted airflow. Make sure that ceiling is able to support
the weight of the unit. See Fig. 3-5 for nominal unit weight.
See submittal drawings and Fig. 3-5 for dimensions.
NOTE: See page 23 for additional requirements for units
ducted to multiple openings.
2. Ensure that bottom panels have been removed from unit.
When unit is lifted, access to the
3
/
4
in. mounting holes is
through the bottom of the unit. Hanger rods and fasteners
and other required hardware must be field supplied.
3. Using a forklift or other mechanical lifting device, raise
the unit to the mounting position. If forklift or other
lifting device is likely to contact a painted wall surface,
protect the surface as necessary.
4. Use rods and fasteners to suspend the unit at the mounting
holes on the top of the unit. The unit must be suspended at
the
3
/
4
in. mounting holes; do not use any other locations.
5. If desired, install field-supplied vibration isolators. Adjust
isolators so unit is uniformly suspended and pitched.
6. To ensure proper drainage and operation, ensure unit is
level and tighten all fasteners. DO NOT mount the unit
on a slope. Pitch of horizontal suspended units can
change after coil is filled; recheck after filling coil.
7. Protect the unit from jobsite debris. Do not allow foreign
material to fall into drain pan. Prevent dust and debris
from being deposited on motor or fan.
