refrigerant for an additional 15 ft. of refrigerant 
lines the same size as the valve fittings.

NOTE: DO NOT USE ANY PORTION OF 
THE CHARGE FOR PURGING OR LEAK 
TESTING.

Matching coils and air handlers may be shipped 
with a small holding charge to pressurize them to 
keep out contaminants. To release the pressure, 
read the indoor section installation instructions 
carefully.

Liquid and Suction Lines — Fully annealed, 
refrigerant grade copper tubing should be used 
when installing the system. Refrigerant suction 
line tubing should be fully insulated. 

Field Connections for Electrical Power 
Supply —
  All wiring must comply with current 
provisions of the “National Electrical Code” 
(ANSI/NFPA 70) and with applicable local 
codes having jurisdiction. The minimum size of 
electrical conductors and circuit protection must 
be in compliance with information listed on the 
outdoor unit data label.

NOTE: Certain models have external panels 

fabricated  from a premium grade of stainless 
steel designed to inhibit corrosion. For such 
units, if the unit is located in a coastal region 
or other area subjected to high concentrations 
of salt, then the unit should be hosed off after 
storms and monthly otherwise to maintain its 
new appearance.

SAFETY CONSIDERATIONS

Pressures within the System — Split 
system heat pump equipment contains liquid 
and gaseous refrigerant under pressure. 
Installation and servicing of this equipment 
should be accomplished by qualified, trained 
personnel thoroughly familiar with this type of 
equipment. Under no circumstances should the 
Homeowner attempt to install and/or service 
the equipment.

Labels, Tags, Precautions — When working 
with this equipment, follow all precautions in the 
literature, on tags, and on labels provided with 
the equipment. Read and thoroughly understand 
the instructions provided with the equipment prior 
to performing the installation and operational 
checkout of the equipment.

Brazing Operations — Installation of equipment 
may require brazing operations. Safety codes 
must be complied with. Safety equipment (e.g.; 
safety glasses, work gloves, fire extinguisher, 

etc.) must be used when performing brazing 
operations.

 WARNING:

Make sure all electrical power to the unit 
is off prior to installing or servicing the 
equipment. Failure to do so may cause 
personal injury or death. 

SITE PREPARATION

Unpacking Equipment — Remove the 
cardboard carton and User’s Manual from the 
equipment. Take care to not damage tubing 
connections when removing from the carton.

Inspect for Damage — Inspect the equipment 
for damage prior to installing the equipment at 
the job site. Ensure coil fins are straight and, if 
necessary, comb fins to remove flattened and 
bent fins.

Preferred Location of the Outdoor Unit at the 
Job Site —
 Conduct a survey of the job site to 
determine the optimum location for mounting 
the outdoor unit. Overhead obstructions, 
poorly ventilated areas, and areas subject to 
accumulation of debris should be avoided. The 
outdoor unit must be installed in such a manner 
that airflow through the coil is not obstructed and 
that the unit can be serviced.

Facility Prerequisites — Electrical power 
supplied must be adequate for proper operation 
of the equipment. The system must be wired and 
provided with circuit protection in accordance 
with local building codes and the National 
Electrical Code.

INSTALLING THE OUTDOOR UNIT

Slab Mount — The site selected for a slab mount 
installation requires a stable foundation and one 
not subject to erosion. The slab should be level 
and anchored (if necessary) prior to placing the 
equipment on the slab.

Cantilever Mount — The cantilever mount 
should be designed with adequate safety factor 
to support the weight of the equipment, and for 
loads subjected to the mount during operation. 
Installed equipment should be adequately 
secured to the cantilever mount and levelled 
prior to operation of the equipment.

Roof Mount — The method of mounting should 
be designed so as not to overload roof structures
