Installation
Unit Location
NOTE: In some cases noise in the living area has been
traced to gas pulsations from improper installation of
equipment.
1. Locate unit away from windows, patios, decks, etc.
where unit operation sounds may disturb customer.
2. Ensure that vapor and liquid tube diameters are
appropriate to capacity of unit.
3. 5XQUH¿JHUDQWWXEHVDVGLUHFWO\DVSRVVLEOHE\DYRLGLQJ
unecessary turns and bends.
4. Leave some slack between structure and unit to
absorb vibration.
5. When passing refrigerant tubes through the wall, seal
opening with RTV or other silicon-based caulk.
6. Avoid direct tubing contact with water pipes, duct work,
ÀRRUMRLVWVZDOOVWXGVÀRRUVZDOOVDQGDQ\VWUXFWXUH
7. Do not suspend refrigerant tubing from joists and
studs with a rigid wire or strap which comes in direct
contact with tubing.
8. Ensure that tubing insulation is pliable and completely
surrounds suction line.
When outdoor unit is connected to factory-approved indoor
unit, outdoor unit contains system refrigerant charge for
operation with indoor unit of the same size when connected

NOTE: Maximum liquid-line size is 3/8 in. O.D. for all
residental applications including long lines.
Outdoor Section
Zoning ordinances may govern the minimum distance the
condensing unit can be installed from the property line.
Install on a Solid, Level Mounting Pad
The outdoor section is to be installed on a solid foundation.
7KLV IRXQGDWLRQ VKRXOG H[WHQG D PLQLPXP RI ´ LQFKHV
beyond the sides of the outdoor section. To reduce the
possibility of noise transmission, the foundation slab
should NOT be in contact with or be an integral part of the
building foundation.
If conditions or local codes require the unit be attached to
pad or mounting frame, tie down bolts should be used and
fastened through knockouts provided in unit base pan.
Rooftop Installations
Mount on level platform or frame 6 inches above roof
surface. Place unit above a load-bearing wall and isolate
unit and tubing set from structure. Arrange supporting
members to adequately support unit and minimize
transmission of vibration to building. Ensure roof structure
and anchoring method is adequate for location. Consult
local codes governing rooftop applications.
NOTE: Unit must be level to within ± 1/4 in./ft per

Indoor Coil Piston Selection
The outdoor section must be matched to a factory approved
indoor section. It is mandatory that the installer ensure that
the correct piston or TXV is installed in the indoor section.
,IQHFHVVDU\UHPRYHWKHH[LVWLQJSLVWRQDQGUHSODFHLWZLWK
the correct piston or TXV. See indoor unit instructions
for details of changing the piston or TXV. Contact your
distributor for accessory piston kits.
The correct piston size is shipped with the outdoor unit,

piston that comes with the indoor unit, unless it matches
the one listed on the outdoor unit.
Refrigeration Line Sets
Use only refrigeration grade copper tubes. Split systems
may be installed with up to 50 feet of line set (no more than
20 feet vertical) without special consideration. For lines 50
feet or longer, refer to long line set guidelines.
Do not leave the lines open to the atmosphere for any
period of time, moisture, dirt and bugs may contaminate
the lines.

type of hanger. Keep both lines separate, and always
insulate the suction line. Long liquid line runs (30 feet or
more) in an attic will require insulation. Route refrigeration
line sets to minimize length.
DO NOT let refrigerant lines come in direct contact with
foundation. When running refrigerant lines through the
foundation or wall, openings should allow for a sound
and vibration absorbing material to be placed or installed
between tubing and foundation. Any gap between

If ANY refrigerant tubing is required to be buried by state
or local codes, provide a 6 inch vertical rise at service
valve.
CAUTION
Before making braze connections, be sure all joints are
clean. Before heat is applied for brazing, dry nitrogen

and scale formation on the inside of the tubing.
The following is the recommended method for making
braze connections at the refrigerant line connections:

or steel brush.
6. ,QVHUWWXELQJLQWRVZDJH¿WWLQJFRQQHFWLRQ

help cool area.
Leak Check
Refrigeration lines and indoor coil must be checked for leaks
after brazing and before evacuation. The recommended
procedure is to apply a trace amount of vapor refrigerant
DSSUR[LPDWHO\WZRRXQFHVRUSVLJLQWRWKHOLQHVHWDQG
indoor coil, then pressurize with 150 psig of dry nitrogen.
Use a refrigerant leak detector to check all joints. The
system may also be checked for leaks using a halide torch
or pressure and soapy solution. After completion of leak
check, relieve all pressure from system before evacuation.
Evacuating and Charging Instructions
It is unlawful to release refrigerants into the atmosphere.
WARNING
These outdoor units are pre-charged at the factory with
adequate refrigerant to handle 15 feet of refrigerant tubing.
1. Connect the vacuum pump to the center hose of the
manifold gauge set, the low-pressure manifold gauge
to the vapor service valve and the high pressure
manifold gauge to the liquid service valve.
2. 7KHYDOYHVVKRXOGEHNHSWLQWKH³IURQWVHDWHG´FORVHG
position. This will allow evacuation of the refrigeration
lines and the indoor coil, without disturbing the factory
charge in the outdoor unit.
3. Follow the vacuum pump manufacturer’s instructions.
Allow the pump to operate until the system has been
evacuated down to 300 microns. Allow the pump to
continue running for an additional 15 minutes. Turn
OFF the pump and leave the connections secured
to the two (2) service valves. After 5 minutes, if the
system fails to hold 1000 microns or less, check all
FRQQHFWLRQV IRU WLJKW ¿W DQG UHSHDW WKH HYDFXDWLRQ
procedure.
4. Isolate the vacuum pump from the system by closing
the shutoff valves on the gauge-set. Disconnect the
vacuum pump.
5. After evacuation of the connecting lines, remove the
VHUYLFHYDOYHFDSDQGIXOO\LQVHUWWKHKH[ZUHQFKLQWRWKH
stem. A back-up wrench is required on the valve body
to open the valve stem. Back-out counterclockwise
until the valve stem just touches the coined edge.

Electrical Connections
ELECTRICAL SHOCK HAZARD!
Turn OFF electric power before connecting
unit, performing any maintenance or
removing panels or doors. More than one
disconnect may be required to turn off all
power.
FAILURE TO DO SO COULD RESULT
IN BODILY INJURY OR DEATH.
WARNING
Be sure to check all local codes to determine that the unit
is installed in accordance with local requirements. Consult
the National Electric Code for wire size requirements. Use
60° C or higher copper wires only. Always provide ground
connections to the outdoor unit. Power supply must agree
with the rating on the unit nameplate.
Provide line voltage power supply to unit from a properly
sized disconnect switch. Route power and ground wires
from disconnect switch to unit. Line voltage connections

of the outdoor unit. Follow the wiring diagram attached to
inside of the access panel.
Proper circuit protection recommendations are indicated
on Unit Rating Plate. Time delay fuses are required to
prevent blowing due to starting current (the current in rush
when equipment starts is reffered to as the Locked Rotor
Amps or LRA).

Start-Up Procedure
1. Close electrical disconnects to energize system.
2. Set room thermostat at desired temperature. Be sure
set point is below indoor ambient temperature.

Adjusting Charge
Factory charge is shown on the rating label located on the
access panel.
All units are factory charged for 15 feet of connecting line
set. Charge should be adjusted for line set lengths other
than 15 feet. For line sets shorter than 15 feet in length,
remove charge. For line sets longer than 15 feet, add
