PRE-INSTALLATION

INSPECTION

Upon receipt of shipment, carefully check the shipment against
the bill of lading. Make sure all units have been received. Inspect
the carton or crating of each unit, and inspect each unit for damage
on both the interior and exterior. Ensure the shipping company
makes proper notation of any shortages or damage on all copies of
the freight bill. Concealed damage not discovered during unload-
ing must be reported to the shipping company within 5 days of re-
ceipt of shipment.
NOTE: It is the responsibility of the purchaser to file all necessary
claims with the shipping company.

STORAGE

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 4-6 for unit dimensions. Be sure to al-
low adequate space around the unit for installation and servicing.
See Fig. 7 for service clearance requirements.

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).
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.
Step 2 — Check Unit
Upon receipt of shipment at the jobsite, carefully check the ship-
ment against the bill of lading. Make sure all units have been
received. Inspect the carton or crating of each unit, and inspect
each unit for damage. Ensure the shipping company makes proper
notation of any shortages or damage on all copies of the freight
bill. Concealed damage not discovered during unloading must be
reported to the shipping company within 5 days of receipt of
shipment.
NOTE: It is the responsibility of the purchaser to file all necessary
claims with the shipping company.

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 configu-
ration.
2. Compare the electrical data on the unit nameplate with to ver-
ify 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.
