1.  Always wear proper personal protection equipment.
2.  Always disconnect electrical power before removing 

panel or servicing equipment.

3.  Keep hands and clothing away from moving parts.
4.  Handle refrigerant with caution; refer to proper MSDS 

from refrigerant supplier.

5.  Use care when lifting, avoid contact with sharp edges.  

Installation

NOTE: 

In some cases, noise in the living area has been 

traced to gas pulsations from improper installation of 

equipment.

•  Locate unit away from windows, patios, decks, etc. 

where unit operation sounds may disturb customer.

•  Leave some slack between structure and unit to 

absorb vibration.

•  Place a sound-absorbing material, such as Isomode, 

under the unit if it will be installed in a location or 

position that will transmit sound or vibration to the 

living area or adjacent buildings.

•  Install the unit high enough above the ground or roof to 

allow adequate drainage of defrost water and prevent 

ice buildup.

•  In heavy snow areas, do not locate the unit where 

drifting snow will occur. The unit base should be 

elevated above the depth of average snows.

NOTE: 

Elevation of the unit may be accomplished 

by constructing a frame using suitable materials. If a 

support frame is constructed, it must not block drain 

holes in unit base.

•  When installed in areas where low ambient 

temperatures exist, locate unit so winter prevailing 

winds do not blow directly into outdoor coil.

•  Locate unit away from overhanging roof lines which 

would allow water or ice to drop on, or in front of, coil 

or into unit.

When outdoor unit is connected to factory-approved indoor 

unit, outdoor unit contains system refrigerant charge for 

operation with matching indoor unit when connected by 15 

ft. of field-supplied tubing. For proper unit operation, check 

refrigerant charge using charging information located on 

control box cover.

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. 

This foundation should extend a minimum of 2” (inches) 

beyond the sides of the outdoor section. To reduce the 

possibility of noise transmission, the foundation slab 

General

Read this entire instruction manual, as well as the 

instructions supplied in separate equipment, before 

starting the installation. Observe and follow all warnings, 

cautions, instructional labels, and tags. Failure to comply 

with these instructions could result in an unsafe condition 

and/or premature component failure.

These instructions are intended as a general guide only 

for use by qualified personnel and do not supersede any 

national or local codes in any way. The installation must 

comply with all provincial, state, and local codes as well as 

the National Electrical Code (U.S.) or Canadian Electrical 

Code (Canada). Compliance should be determined prior 

to installation.

This unit uses R-410A, which is an ozone-friendly HFC 

refrigerant. The unit must be installed with a matching 

indoor coil and line set. A filter drier approved for use with 

R-410A is installed in the unit.

When servicing or repairing HVAC components, ensure 

the fasteners are appropriately tightened. Table 1 shows 

torque values for fasteners.

Inspection of Shipment

Upon receipt of equipment, carefully inspect it for possible 

shipping damage. If damage is found, it should be noted 

on the carrier’s freight bill. Take special care to examine 

the unit inside the carton if the carton is damaged. Any 

concealed damage discovered should be reported to the 

last carrier immediately, preferably in writing, and should 

include a request for inspection by the carrier’s agent.

If any damages are discovered and reported to the carrier 

DO NOT INSTALL THE UNIT

, as claim may be denied.

Check the unit rating plate to confirm specifications are as 

ordered.

Safety Precautions

Follow all safety codes. Wear safety glasses and work 

gloves. Use quenching cloth for brazing operations. 

Have fire extinguisher available. Read these instructions 

thoroughly and follow all warning or cautions attached to 

the unit.
