CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and wear appropriate clothing.
These instructions cover minimum requirements and conform to existing national standards and safety codes. In some instances, these instructions exceed certain local codes and ordinances,
especially those that may not have kept up with changing residential construction practices. We require these instructions as a
minimum for a safe installation. GENERAL -- 50ZP cooling units are fully self-contained and
designed for outdoor installation. See Fig. 1. As shown in Fig. 2-4, units are shipped in a horizontal-discharge configuration for
installation on a ground-level slab. All units can be field-converted to downflow discharge configurations for rooftop
applications with a field-supplied plenum
RECEIVING AND INSTALLATION
Step 1 -- Check Equipment
IDENTIFY UNIT -- The unit model number and serial number are stamped on the unit identification plate. Check this information
against shipping papers. INSPECT SHIPMENT -- Inspect for shipping damage while unit
is still on shipping pallet. If unit appears to be damaged or is torn loose from its securing points, have it examined by transportation
inspectors before removal. Forward claim papers directly to transportation company. Manufacturer is not responsible for any
damage incurred in transit. Check all items against shipping list. Immediately notify the
nearest Carrier Air Conditioning office if any item is missing. To prevent loss or damage, leave all parts in original packages until
installation.
Step 2 -- Provide Unit Support
SLAB MOUNT -- Place the unit on a rigid, level surface, suitable to support the unit weight. The flat surface should extend approximately 2-in. (51 mm) beyond the unit casing on the 2
sides. The duct connection side and condensate drain connection sides should be flush with the edge of the flat surface. A concrete
pad or a suitable fiberglass mounting pad is recommended. A 6-in. (152 mm) wide gravel apron should be used around the
flat surface to prevent airflow blockage by grass or shrubs. Do not secure the unit to the flat surface except where required by local
codes. The unit should be level to within 1/4 in. (6 mm). This is necessary
for the unit drain to function properly,
Step 3 -- Provide Clearances
The required minimum service clearances and clearances to
combustibles are shown in Fig. 2-4. Adequate ventilation and condenser air must be provided.
The condenser fan pulls air through the condenser coil and discharges it through the fan on the top cover. Be sure that the fan discharge does not recirculate to the condenser coil. Do not locate
the unit in either a corner or under an overhead obstruction. The minimum clearance under a partial overhang (such as a normal
house overhang) is 48 in. (1219 mm) above the unit top. The maximum horizontal extension of a partial overhang must not
exceed 48 in. (1219 mm). Do not place the unit where water, ice, or snow from an overhang
or roof will damage or flood the unit. The unit may be installed on wood flooring or on Class A, B, or C roof covering materials.
Step 4 -- Place Unit
Unit can be moved with the handholds provided in the unit basepan. Refer to Table 1 for operating weights. Use extreme caution to prevent damage when moving the unit. Unit must
remain in an upright position during all moving operations. The unit must be level for proper condensate drainage; the
ground-level pad must be level before setting the unit in place. When a field-fabricated support is used, be sure that the support is level and that it properly supports the unit.
Step 5 -- Select and Install Ductwork
The design and installation of the duct system must be in
accordance with:
• the standards of the NFPA (National Fire Protection Association) for installation of nonresidence-type air conditioning and ventilating systems;
• NFPA90A or residence-type, NFPA90B; and/or local codes and residence-type, NFPA 90B;
• and/or local codes and ordinances.
Select and size ductwork, supply-air registers and return-air grilles according to ASHRAE (American Society of Heating,
Refrigeration, and Air Conditioning Engineers) recommendations. Use the duct flanges provided on the supply- and return-air
openings on the side of the unit. See Fig. 2-4 for connection sizes
and locations. The 14-in. (356 mm) round duct collars (size 036-048 units) are shipped inside the unit attached to the indoor blower. They are field-installed and must be removed from the
indoor cavity prior to start-up, even if they are not used for installation.
INSTALL FLANGES FOR DUCTWORK CONNECTIONS (50ZP060 ONLY) -- The 50ZP060 units are shipped with flanges
which must be field-installed on the unit. To install unit flanges:
1. Five pieces of flange are shipped on the return-air opening of the unit. Remove the flanges from the shipping position.
See Fig. 5. Screws are field-supplied.
2. One piece of flange is used as it is shipped (straight). Bend the other 4 pieces at right angles.
3. Install the straight flange on the right side of the return-air opening in holes provided. See Fig. 6. Flanges should stick
out from unit to allow for connection of ductwork.
4. Install 2 hand-formed flanges onto return air opening in holes provided to form a rectangle around the return air
opening.
5. Install remaining 2 hand-formed flanges around discharge air opening in holes provided.
6. Ductwork can now be attached to flanges.
When designing and installing ductwork, consider the following:
[]NIT DAMAGE HAZARD
Failure to follow this caution may result in damage to unit components.
When connecting ductwork to units, do not drill deeper than 3/4 in. (19.1 mm) in shaded area shown in Fig. 7 or coil ma}zbe damaged.
• All units should have field-supplied filters installed in the
return-air side of the unit. Recommended sizes for filters are shown in Table 1.
• Avoid abrupt duct size increases and reductions. Abrupt change
in duct size adversely affects air performance. Use flexible connectors between ductwork and unit to prevent transmission of
vibration. Use suitable gaskets to ensure weathertight and airtight seal.
• Size ductwork for cooling air quantity (CFM).
• Insulate and weatherproof all external ductwork. Insulate and cover with a vapor barrier all ductwork passing through
conditioned spaces. Follow latest Sheet Metal and Air Conditioning Contractors National Association (SMACNA) and
Air Conditioning Contractors Association (ACCA) minimum installation standards for residential heating and air conditioning
systems.
• Secure all ducts to building structure. Flash, weatherproof, and vibration-isolate duct openings in wall or roof according to good
construction practices. Fig. 8 shows a typical duct system with 50ZP unit installed.

ELECTRICALSHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Before performing service or maintenance operations on the system, turn off main power to unit and install lockout tag.
There may be more than one disconnect switch.
Units are dedicated side supply )roducts. They are not convertible to vertical air supply. A field-supplied plenum must be used to convert to vertical air discharge.
Step 6 -- Charging Unit
Unit is shipped with a nitrogen holding charge only. Slowly release nitrogen charge from unit using service gages and using a vacuum
pump evacuate unit to 500 microns or lower. To locate charging ports, remove top panel which provides access to control box and
blower. Charging ports are located under top panel. Charge unit by weight using an electronic scale. R-22 charge quantity can be
found in table 1 and on unit rating plate. Do not over charge.
Step 7 -- Provide for Condensate Disposal
NOTE: Be sure that condensate-water disposal methods comply with local codes, restrictions, and practices.
Unit removes condensate through a 1-3/64 -in. (26.6 mm) ID hole which is located at the end of the unit. See Fig. 2-4 for location of
condensate connection.
