Introduction; Pre-Installation; Unpack And Inspect Units; Protect Units From Damage - Carrier 40UV Installation, Start-Up And Service Instructions Manual

INTRODUCTION

This document contains general installation instructions for the
40UV, UH unit ventilators. Refer to the unit wiring diagram or to
specific manufacturer literature for any other type of
factory-mounted controls.
See submittal drawings for unit configurations, dimensions,
clearances, and pipe connections. Refer to unit wiring label for all
electrical connections; follow NEC (National Electrical Code) and
local codes.
IMPORTANT: Units can be requested with special features by
requesting an ETO. This manual only covers standard features
and does not include any changes made for special feature
requests by the customer. Units built with special features are
noted with a 5-digit SPO (Special Product Order) Number on the
Serial Plate.

PRE-INSTALLATION

Unpack and Inspect Units

Inspect unit upon arrival. In case of damage, report it immediately
to transportation company and your local factory sales
representative.
Check rating plate on unit to verify that power supply meets avail-
able electric power at the point of installation.
Inspect unit received for conformance with description of product
ordered (including specifications where applicable).
Appliances must not be installed where they may be exposed
to potentially explosive or flammable atmosphere.
IMPORTANT: The installation and maintenance instructions in
this manual must be followed to provide safe, efficient, and
trouble-free operation.
In addition, particular care must be exercised regarding the spe-
cial precautions listed below.
Failure to properly address these critical areas could result in
property damage or loss, personal injury, or death. These instruc-
tions are subject to any more restrictive local or national codes.

Protect Units from Damage

Each unit will be shipped to the site secured to a wood skid using
metal brackets. Whenever possible, all lifting and handling of the
unit should be done with the packing and skid in position.
Due to the length of the unit, 72 in. forklift tines are recommended
to avoid damaging the unit. Remove the metal brackets prior to
lifting the unit off of the skid. When slinging or using a forklift to
lift the unit, the support points should be sufficiently apart to give
stability when lifting. Unless otherwise noted the lifting points
should be equidistant from the centerline. Extreme care should be
taken not to drop the unit. Considerable damage can occur to the
unit during positioning, in particular, to the paneling and exterior
paint. Use an adequate number of personnel and the correct tools
when moving the unit.
A lifting device such as a forklift is needed to install this product.
A special key is provided with the unit for use with the
tamper-proof cabinet locks on the top and front panels. The use of
torque screwdrivers on panel, cover, or component mounting
screws is not recommended. Hand-start all screws. If electric drills
are used, set at the lowest possible torque.
DANGER

Prepare Jobsite for Unit Installation

To save time and to reduce the possibility of costly errors, set up a
complete sample installation in a typical room at jobsite. Check all
critical dimensions such as pipe, wire, and duct connection
requirements. See figures in Step 1 on page 5 for mounting loca-
tions. Refer to job drawings and product dimension drawings on
pages 6-9. Confirm that building construction is adequate to sup-
port the unit. See Table 1 for unit weight data. Instruct all trades in
their part of the installation.
1. Select the unit location. Ensure the wall or ceiling structure is
adequate for the required mounting provisions as outlined in
the "INSTALLATION" section. For Ceiling Mounted units,
check that ceiling is capable of supporting the weight of the
unit.
2. Before installation, ensure that the correct electrical power
supplies are available for the unit.
3. Each unit requires an independently fused and isolated power
supply.
4. If the installation has multiple units, check that unit model
and tagging corresponds with the installation plans. Please
contact your Carrier representative immediately if discrepan-
cies are noted.
5. Check to make sure that the units will have adequate installa-
tion clearance around them.
6. Note that units with cooling coils will have a condensate con-
nection at the rear and suitable provisions should be made for
draining. If multiple units tee into a common drain manifold,
it must be sized to ensure free draining with all the units in
operation.
7. For units with outside air, inspect the wall sleeve installation
for gaps that would allow leakage of outdoor air into the
space. All joints and abutments should be sealed with water-
proof sealant.

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 re-installation later.
3. Rotate the fan shaft by hand to ensure that fans are unre-
stricted and can rotate freely. Check for shipping damage
and fan obstructions.

Drainage

Units with cooling coils have a condensate drain pan connection
and 3/4 in. ID (Inside Dimension) condensate line. The conden-
sate drain pan connection is field changeable and can be mounted
on either the left or right side of the unit. To change the connection
location, remove the condensate line from the elbow. Remove the
elbow from the drain pan and remove the plug from the opposite
side of the drain pan. Re-install the elbow and the plug on the op-
posite sides of the drain pan. Re-connect the condensate line.
