HORIZONTAL UNITS (50PCH)
Horizontal units are designed for indoor installation only. Be sure
to allow adequate space around the unit for installation and
servicing. See Fig. 1 for overall unit dimensions.
VERTICAL UNITS (50PCV)
Vertical units are designed for indoor installations only. Vertical
units are typically installed in a floor-level closet or a small
mechanical room, Be sure to allow adequate space around the unit
for installation and servicing. See Fig. 2 for overall unit
dimensions.
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 me-
chanical components and filters used in these units quickly be-
come 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 provides
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
servicing of the blower and blower motor, compressor,
refrigerant circuit, controls, and coils.
8.
For units with free return (non-ducted), provide adequate
space for proper return airflow. For units installed in closets
or mechanical rooms, provide sufficient return grill area for
proper airflow.
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 that are installed in enclosed spaces (such as furred
in closets or behind finished ceilings), provide access panels
to allow for the installation, maintenance, service, and
removal of the unit.
IMPORTANT: It is the installing contractor's responsibility to
ensure that all equipment is installed with proper access for
service, start-up, installation of accessories, configuration of
control and other components, and equipment removal in
accordance with Carrier's recommended service clearances 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.
Step 2 — Check Unit
Upon receipt of equipment at the jobsite, inspect the carton or
crating of each unit, and inspect each unit for damage on both the
interior and exterior. Note any damage and contact your local
equipment sales office.
EQUIPMENT DAMAGE HAZARD
DO NOT store or install units in corrosive environments or in
locations subject to temperature or humidity extremes (e.g., at-
tics, garages, rooftops, etc.). Corrosive conditions and high
temperature or humidity can significantly reduce performance,
reliability, and service life. Always move units in an upright
position. Tilting units on their sides may cause equipment
damage.
INSPECT UNIT
To prepare the unit for installation, complete the procedures listed
below:
1.
Verify that the correct unit has been received. Check the unit
capacity (tonnage), voltage, orientation, and configuration.
2.
Compare the electrical data on the unit nameplate with to
verify the jobsite power feed (voltage, amperage, MCA) and
power protection (MOCP).
3.
Verify that the unit is the correct model for the entering water
temperature of the job (standard or extended range)
4.
Remove the unit packaging, keeping the unit attached to the
shipping pallet. Do not destroy packaging. Save for re-instal-
lation on the unit if the unit will not be fully installed.
5.
Open a unit access panel. Verify that the refrigerant tubing is
free of kinks or dents, and that it does not touch other unit
components.
6.
Check the water piping and piping connections to make sure
they are free from defects, kinks, dents, and appear to be
water tight. Verify system operating water pressure.
7.
Inspect the blower assembly. Verify that the blower has not
come lose during shipping. Verify clearance between the
blower wheel and the blower housing. Verify free blower
rotation.
8.
Inspect all electrical connections. Be sure connections are
clean and tight at the terminals.
9.
Check unit controls. If Better B, Complete C, or Deluxe D,
verify field provided thermostat is available. If WSHP Open,
verify proper sensor has been provided and a commissioning
interface will be available.
10. 50PCH Only - Locate the hanging bracket kit located in the
compressor compartment.
11. Remove the foam blower shipping support from underneath
the blower section.
12. Remove any shipping brackets from the unit.
