GENERAL
These condensing units are designed for outdoor
installation on a roof or at ground level. Every unit is
completely piped and wired at the factory and is
shipped ready for immedi ate installation. Only the liquid and suction lines to the evaporator coi l, the control
wiring and the main power wiring are required to complete the installation. Each unit is dehydrate d, evacuated, leak tested and pressure tested at 450 psig
before being pressurized with a holding charge of
refrigerant-22 for shipment and/or storage.
All controls are located in the front of the unit and are
readily accessible for maintenance, adjustment and
service. All wiring (power and control) can be made
through the front of the unit.

3. The condensing unit shoul d not be installed w here
normal operating sounds may be objectionable. On
either rooftop or ground level installations, rubber
padding can be applied between the base rails and
their supports to lessen any transmission of vibration.
4. All units require certain clearances for proper operation and service. Refer to General Installation
Form 55.70-N1 for additional guidelines.

INSTALLATION
LIMITATIONS
These units must be installed in accordance with all
national and local safety codes. If no local codes apply,
installation must conform with the appropriate national
codes. See Table 2 for Unit Application Data. Units are
designed to meet National Safety Code Standards.
If components are to be add ed to a unit to meet local
codes, they are to be installed at the dealer's and/or
the customer's expense.
LOCATION
Use the following guidelines to select a suitable location for these units.
1. The condensing unit is designed for outdoor installation only. The condenser fans are the propeller
type and are not suitable for use with duct work.
2. The condensing unit and the evaporator blower
should be installed as close together as possible
and with a minimum number of bends in the refrigerant piping. Refer to “REFRIGERANT PIPING” for
additional information.
Be careful not to dam age t he roo f. Consult t he building
contractor or architect if the roof is bonded . Choose a
location with adequate structural strength to support
the unit.
The condensing unit must be mounted on solid level
supports. The supports can be c hannel iron beams or
wooden beams treated to reduce deterioration.
A minimum of two (2) beam s are required to support
each unit. The beams should: (1) Be positioned perpendicular to the roof joists. (2) Extend beyond the
dimensions of the unit to distribute the load on the roof.
(3) Be capable of adequately supporting t he entire unit
weight. Refer to Center of Gravity and Point Load Figures and Physical Data Table for load distribution and
weights.
These beams can u sually be set directly on the roof.
Flashing is not required.
NOTE: On bonded roofs, check for special installation
requirements.
GROUND LEVEL LOCATIONS
The units must be inst alled on a one-piece level concrete slab with a minimum thickness of 4 inches. The
length and width should be at least 6 inches greater
than the units overall base dimensions. Refer to
Figure 4.
Unitary Prod ucts Group 5
Footers under the slab that extend below the frost line
is recommended. Any strain on the refrigerant lines
may cause a refrigerant leak. The slab should not be
tied to the building foundation because noise and vibration will telegraph into your struc ture.
A unit can also be support ed by conc rete piers. These
piers should (1) extend below the frost line, (2) be
located under the unit's four corners, and (3) be sized
to carry the entire unit weight. Refer to Figure 1 and
Table 1 for the center of gravity and unit weight.
Care should be taken to protect the unit from
tampering and unauthorized persons from
injury. Screws on access panels will prevent
casual tampering. Additional safety precautions such as fences around the unit or locking
devices on the panels may be advisable.
Check local authorities for safety regulations.
035-18204-001-B-0703
Do not use straps under the unit or through the
fork lift slots for lifting purposes. Sharp metal
edges can damage the straps and could result
in personal injury or equipment damage.
BEFORE LIFTING A UNIT, MAKE SURE THAT ITS
WEIGHT IS DISTRIBUTED EQUALLY ON THE
STRAPS SO THAT IT WILL LIFT EVENLY.
LENGTH OF FORKS MUST BE A MINIMUM OF 42"
for 7-1/2 ton units or a MINIMUM OF 54" for 10 ton
units when lifting across the long dimension.
Remove the nesting brackets from the four corners on
top of the unit. All screws that are removed to take
these brackets off must be replaced on the unit.
RIGGING AND HANDLING
Exercise care when moving the unit. Do not remove
any packaging until the unit is near the place of installation.

Rig the unit by attaching nylon straps with hooks to the
lifting holes provided in the base rails. Spreaders,
whose length exceeds the largest dimension across
the unit, MUST be used across the top of the u nit if the
rigging height above the top of the unit is less than 5
feet. See Figure 2.
