designed for outdoor installation on a rooftop or a slab. Field­installed electric heater accessories are available to provide
supplemental electric heat combined with electric cooling and
heating.

The units are completely assembled on rigid, removable
base rails. All piping, refrigerant charge, and electrical wiring
is factory installed and tested. The units require only electric
power and duct connections at the point of installation.

The electric heaters have nickel-chrome resistance wire ele
ments and utilize single point power connection.

INSPECTION

As soon as a unit is received, it should be inspected for pos
sible damage during transit. If damage is evident, the extent
of the damage should be noted on the carrier's freight bill. A
separate request for inspection by the carrier's agent should
be made in writing. Refer to Form 50.15-NM for additional in
formation.

Installer should pay particular attention to the words: NOTE, CAUTION and WARNING. Notes are intended to clarify or
make the installation easier.Cautions

LIMITATIONS

These units must be installed in accordance with the follow
ing national and local safety codes.

1. National Electrical Code ANSI/NFPS No. 70 or Canadian
Electrical Code Part 1, C22.1 (latest editions).

2. Local plumbing and waste water codes and other applica
ble local codes.

Refer to Table 1 for unit application data and to Table 4 for
electric heat application data.

If components are to be added to a unit to meet local codes,
they are to be installed at the dealer's and/or the customer's ex­pense.

Size of unit for proposed installation should be based on
heat loss/heat gain calculations made in accordance with in­dustry recognized procedures identified by the Air Condition
ing Contractors of America.

LOCATION

Use the following guidelines to select a suitable location for
these units.

1. Unit is designed for outdoor installation only.

2. Condenser must have an unlimited supply of air. Where a
choiceof locationispossible, positionuniton eithernorthor
east side of building.

3. For ground level installation, a level pad or slab should be
used.The thicknessandsize ofthepad orslabused should
meet local codesand unit weight. Do not tie theslab to the
building foundation.

4. For roof top installation, be sure the structure will support
the weight of the unit plus any field installed components.

2 Unitary Products Group

Unit must be installed on a level roof curb or appropriate
angle iron frame providing adequate support under the
compressor/condenser section.

5. Maintain level tolerance of unit to 1/8" maximum.

RIGGING OR HANDLING

Care must be exercised when moving the unit. Do not re
move any packaging until the unit is near the place of instal
lation. Rig unit with slings placed under the unit. Spreader
bars of sufficient length should be used across the top of the
unit.

BEFORE LIFTING A UNIT, MAKE SURE THAT ITS WEIGHT
IS DISTRIBUTED EQUALLYON THE CABLES SO THAT IT
WILL LIFT EVENLY.

Units may also be moved or lifted with a fork-lift. Slotted
openings in the skid are provided for this purpose. Forks
must pass completely through the base.

Refer to Table 2 for unit weights and to Figure 1 for approxi
mate center of gravity.

CLEARANCES

All units require certain clearances for proper operation and
service. Refer to Figure 3 for the clearances required for
combustion, construction, servicing and proper unit opera
tion.

CAUTION: When fastening duct work to the side duct flanges on

theunit, insertthescrewsthroughtheductflanges only .
DONOT insertthescrews throughthecasing. Outdoor
duct work must be insulated and waterproofed.

-

NOTE: Be sure to note supply and return openings.

WARNING:Donotpermitoverhanging structures or shrubs to

obstruct the condenser air discharge outlet.

DUCT WORK

These units are adaptable to downflow use as well as rear
supply and return air duct openings. To convert to downflow,
use the following steps:

1. Remove the duct covers found in the bottom return and
supply air duct openings. There are four (4) screws secur
ing each duct cover (save these screws to use later).

2. Installtheduct covers,removedin stepone,to therearsup
ply and return air duct openings. Secure with the four (4)
screws used in step one.

3. Seal duct covers with silicone caulk.

Downflow units must have an “L”-shaped supply duct without
any outlets or registers located below the outlet of the unit.

Duct work should be designed and sized according to the
methods of the Air Conditioning Contractors of America
(ACCA), as set forth in their Manual D.

A closed return duct system shall be used. This shall not pre­clude use of economizers or ventilation air intake. Flexible
joints may be used in the supply and return duct work to mini­mize the transmission of noise.

Refer to Figure 3 for information concerning rear and bottom
supply and return air duct openings.

FILTERS

Singlephase unitsareshipped withouta filterandistheresponsi
bilityof theinstaller tosecure afilter inthe returnair ductworkor
install a Filter/Frame Kit (1FF0114).

A filter rack and high velocity filters are standard on three
phase units.

-

Filters must always be used and must be kept clean. When
filters become dirt laden, insufficient air will be delivered by

-

the blower, decreasing your units efficiency and increasing
operating costs and wear-and-tear on the unit and controls.

Filters should be checked monthly especially since this unit is
used for both heating and cooling.

CONDENSATE DRAIN

A condensate trap is required to be installed in the conden­sate drain. The plumbing must conform to local codes. Use a
sealing compound on male pipe threads. Install the conden­sate drain line (

3

“ NPTF) to spill into an open drain.

NOTE: 1. Deduct these resistance values from the available external static pressure shown in the respective Blower Performance Table.

2. The pressure thru the economizer is greater for 100% outdoor air then for 100% return air. If the resistance of the return air duct system is less then 0.25 IWG, the unit will deliver
less CFM during full economizer operation.
