DESCRIPTION
Both the outdoor and indoor units are completely piped and
wired at the factory and are shipped ready for immediate
installation. Only the interconnecting liquid and suction lines,
control wiring, and the main power wiring are required to
complete the installation. Every outdoor unit is dehydrated,
evacuated, leak tested and pressure tested at 450 psig
before being pressurized with a holding charge of refrigerant-
22 for shipment and/or storage.
To eliminate the costly cabinet deterioration problems usually
associated with outdoor equipment, all sheet metal parts are
constructed of commercial grade (G90) galvanized steel.
After fabrication, each part is thoroughly cleaned to remove
any grease or dirt from its surfaces. The parts that will be
exposed to the weather are then coated with a desert sand
powder paint to assure a quality finish for many years. This
coating system has passed the 750-hour, salt spray test per
ASTM Standard B117.
APPLICATION FLEXIBILITY OUTDOOR
The outdoor units are lightweight and can be installed on
almost any roof.
Units can be lifted using nylon straps with hooks at the holes
provided in the base rails, or they may be lifted with a forklift
through the slotted openings in the base rails.
A quality appearance and low sound levels make these units
suitable for most ground level locations.
APPLICATION FLEXIBILITY INDOOR
The indoor units are built in a single cabinet with one conden-
sate drain pan. These units can be installed in either the verti-
cal or horizontal position for maximum flexibility.
NOTE: On vertical applications, the air velocity across the
indoor coil keeps the condensate from dripping off
the finned surface onto the filters.
NOTE: On horizontal applications the unit must be installed
with the condensate drain pan under the entire
indoor coil.
NOTE: The Supply Air Plenum and the Return Air Grille
accessories can be used on either arrangement.
NOTE: The Base accessory can only be used on the verti-
cal arrangement.

INDOOR UNIT
Every unit includes a well-insulated cabinet, copper tube/alu-
minum fin coil with interlaced circuiting arrangement, 2"
throwaway filters, adjustable TXV’s and centrifugal blowers.
Blower motors and drive kits are ordered separately. Power
wiring for blower motor is field supplied.
The controls include 208/230/460 or 575 volt transformer,
blower motor contactor and relay, and a low voltage terminal
block.
The units are shipped in the vertical position ready for field
installation. For horizontal installation, the blower module can
be repositioned in the field as shown on pages 3 and 6 for
maximum flexibility.
ACCESSORIES INDOOR UNIT
(FIELD INSTALLED)
• Supply Air Plenums and Return Air Grilles (expanded
metal) accessories are available for free-standing indoor
(15 Ton units only) units located in the conditioned space.
Both accessories are finished to match the exterior of the
basic unit, and both can be applied with either vertical or
horizontal units. The supply air plenums are fully insulated
and have double-deflection, adjustable grilles.
• Base Sections are available to raise vertical indoor units
above the floor. Outdoor air may be introduced through
these bases by cutting an access opening for the out-
door air duct connection. These bases are finished to
match the exterior of the basic unit. They may have to be
insulated in the field for certain applications.
• Suspension Kit is available for indoor units installed hori-
zontally.
• Manual and electronic two stage thermostats are avail-
able for cooling applications.
• Both thermostats have a two-position fan switch, AUTO
and ON to provide intermittent or continuous blower
operation.

REFRIGERANT PIPING
GENERAL GUIDELINES
Many service problems can be avoided by taking adequate
precautions to provide an internally clean and dry system and
by using procedures and materials that conform with estab-
lished standards.
Use hard drawn copper tubing where no appreciable amount
of bending around pipes or other obstructions is necessary.
Use long radius ells wherever possible with one exception -
small radius elbows for the traps in all vapor risers. If soft cop-
per is used, care should be taken to avoid sharp bends which
may cause a restriction.
Pack fiber glass insulation and a sealing material such as
permagum around refrigerant lines where they penetrate a
wall to reduce vibration and to retain some flexibility.
Support all refrigerant lines at minimum intervals with suitable
hangers, brackets or clamps.
Insulate all vapor lines with a minimum of 1/2” ARMA-FLEX
or equal. Liquid lines exposed to direct sunlight and/or high
temperatures must also be insulated.
Never solder vapor and liquid lines together. They can be
taped together for convenience and support purposes, but
they must be completely insulated from each other.
LINE SIZING
When sizing refrigerant lines for a split-system air conditioner,
check the following:
1. Suction line pressure drop due to friction at full capacity,
2. Liquid line pressure drop due to friction at full capacity,
3. Suction line velocity for oil return at part capacity, and
4. Liquid line pressure drop due to static head.
NOTE: Never base refrigerant line sizes on the OD of the
suction and liquid connections on the unit.
Tables 13 and 14 list friction losses for both the suction and
liquid lines on the system. Table 12 shows the amount of
refrigerant charge required per foot of refrigerant line.
When the evaporator coil is below the condensing unit, the
suction line must be sized for both pressure drop and for oil
return. For certain piping arrangements, different suction line
sizes may have to be used. The velocity of the suction gas
must always be great enough to carry oil back to the com-
pressor.
When the condensing unit is below the evaporator coil, the
liquid line must be designed for the pressure drop due to both
friction loss and vertical rise. If the total pressure drop
exceeds 40 psi, some refrigerant may flash before it reaches
the thermal expansion valve. This flashing will not only cause
erratic valve operation and poor system performance, but
could also damage the expansion valve.

1. All horizontal suction lines should be pitched at least 1 inch every 20 feet in the direction of the refrigerant flow to aid the return of
oil to the compressor.
2. Every vertical suction riser greater than 25 feet in height should have a “P” trap at the bottom to facilitate the return of oil to the
compressor. Use short radius fittings for these traps.
3. Based on Refrigerant-22 at the nominal capacity of the condensing unit, a saturated suction temperature of 45°F and a liquid tem-
perature of 110°F.
4. Although suction lines should be sized for a friction loss equivalent to a 2°F change in saturation temperature (or approximately
3psi), sizing the lines for the proper return of oil is more important.
5. These friction losses do not include any allowances for valves or fittings.

1. Based on Refrigerant-22 at the nominal capacity of the condensing unit, a saturated suction temperature of 45°F and a liquid tem-
perature of 110°F.
2. The total pressure drop of the liquid line for both friction and vertical rise must not exceed 40 PSI. If the pressure drop exceeds 40
PSI, the liquid refrigerant could flash before it reaches the expansion valve. This flashing will not only cause erratic valve opera-
tion and poor system performance, but could also damage the expansion valve.
3. These friction losses do not include any allowances for a strainer, filter-drier, solenoid valve, isolation valve or fittings.
