If the equipment is not needed for immediate installation upon its
arrival at the job site, it should be left in its shipping carton and
stored in a clean, dry area between 50°F and 95°F. Units must only
be stored or moved in the normal upright position as indicated by
the UP arrows on each carton at all times. DO NOT STACK
UNITS.
INSTALLATION
Step 1 — Check Jobsite
Installation, operation and maintenance instructions are provided
with each unit. Before unit start-up, read all manuals and become
familiar with the unit and its operation. Thoroughly check out the
system before operation. Complete the inspections and instruc-
tions listed below to prepare a unit for installation. See Table 1
for unit physical data.
HORIZONTAL UNITS (50HQP)
Horizontal units are designed for indoor installation only, using
hanging brackets. See Fig. 1 for the field-installed VFD shipping
location. See Fig. 2 and 3 for overall unit dimensions. Be sure to
allow adequate space around the unit for installation and servicing.
See Fig. 7 for service clearance requirements.
VERTICAL UNITS (50VQP)
Vertical units are designed for indoor installations only. Vertical
units are typically installed in a floor-level mechanical room or in
the occupied space. See Fig 2-6 for unit dimensions. Be sure to al-
low adequate space around the unit for installation and servicing.
See Fig. 4 for service clearance requirements. See Fig. 8 and 9 for
take apart construction units.
CAUTION
EQUIPMENT DAMAGE HAZARD
To avoid equipment damage, do not use these units as a source
of heating or cooling during the construction process. The
mechanical components and filters used in these units quickly
become clogged with construction dirt and debris which may
cause system damage.
INSTALLATION GUIDELINES (ALL UNITS)
1.
Be sure that the location chosen for unit installation pro-
vides ambient temperatures maintained above freezing.
2.
Be sure the installation location is isolated from sleeping
areas, private offices and other acoustically sensitive
spaces.
3.
Be sure unit is mounted at a height sufficient to provide an
adequate slope of the condensate lines. If an appropriate
slope cannot be achieved, a field-supplied condensate
pump may be required.
4.
On horizontal units, allow adequate room below the unit
for condensate drain trap and do not locate the unit above
supply piping.
5.
Provide sufficient space for duct connection. Do not allow
the weight of the ductwork to rest on the unit.
6.
Provide adequate clearance for filter replacement and
drain pan cleaning. Do not allow piping, conduit, etc. to
block filter access.
7.
Provide sufficient access to allow maintenance and servic-
ing of the blower and blower motor, compressor and coils.
Removal of the entire unit from the installation area
should not be necessary.
8.
Provide an unobstructed path to the unit within the closet
or mechanical room. Space should be sufficient to allow
return air to freely enter the space.
9.
Provide ready access to water valves and fittings, and
screwdriver access to unit side panels, discharge collar,
and all electrical connections.
10. Where access to side panels is limited, pre-removal of the
control box side mounting screws may be necessary for
future servicing.
11. For units with dual supply fan outlets, ensure the installa-
tion area has sufficient clearance for a pair of pants duct
discharge.
12. 50HQP only - for units with SAV
option, select installation location for the VFD. If VFD
location results in motor wiring that exceeds 10 ft, con-
sider use of shaft grounding rings (field provided).
IMPORTANT: It is the installation contractors responsibility to
ensure that all equipment is installed with proper access for
service, installation, and removal in accordance with Carrier's
recommended service clearance and installation instructions.
Please refer to the Carrier Commercial WSHP Warranty
Statement (document number 04-570008-01) for details on
warranty exclusions regarding equipment access, removal and
clearances.
