SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock, or other
conditions which may cause death, personal injury, or property
damage. Consult a qualified installer, service agency, or your
distributor or branch for information or assistance. The qualified
installer or agency must use factory-authorized kits or accessories
when modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.
Follow all safety codes. Wear safety glasses, protective clothing,
and work gloves. Use quenching cloth for brazing operations.
Have fire extinguisher available. Read these instructions thor-
oughly and follow all warnings or cautions included in literature
and attached to the unit. Consult local building codes and National
Electrical Code (NEC) for special requirements.
Recognize safety information. This is the safety-alert symbol
When you see this symbol on the unit and in instructions or
manuals, be alert to the potential for personal injury.
Understand these signal words; DANGER, WARNING, and
CAUTION. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which will result in
severe personal injury or death. WARNING signifies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices which would result in minor personal
injury or product and property damage. NOTE is used to highlight

or operation.
WARNING: Before installing, modifying, or servicing
system, main electrical disconnect switch must be in the
OFF position. There may be more than 1 disconnect
switch. Lock out and tag switch with a suitable warning
label. Electrical shock can cause personal injury or death.
CAUTION: Puron® systems operate at higher pressures
than standard R-22 systems. To avoid damage to the unit
or possible personal injury, do not use R-22 service
equipment or components on Puron® equipment.
INSTALLATION RECOMMENDATIONS
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 sound may disturb customer.
2. Ensure that vapor and liquid tube diameters are appropriate
to capacity of unit.
3. Run refrigerant tubes as directly as possible by avoiding
unnecessary 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 pliable silicon-based caulk. (See
Fig. 2.)
6. Avoid direct tubing contact with water pipes, duct work,
floor joists, wall studs, floors, and walls.
7. Do not suspend refrigerant tubing from joists and studs with
a rigid wire or strap which comes in direct contact with
tubing. (See Fig. 2.)
8. Ensure that tubing insulation is pliable and completely
surrounds vapor tube.
9. When necessary, use hanger straps which are 1 in. wide and
conform to shape of tubing insulation. (See Fig. 2.)
10. Isolate hanger straps from insulation by using metal sleeves
bent to conform to shape of insulation.
When outdoor unit is connected to factory-approved indoor unit,
outdoor unit contains system refrigerant charge for operation with
ARI rated indoor unit when connected by 15 ft of field-supplied or
factory accessory tubing. For proper unit operation, check refrig-
erant charge using charging information located on control box
cover and/or in the Check Charge section of this instruction.
IMPORTANT: Maximum liquid-line size is 3/8-in. O.D. for all
residential applications including long line.
IMPORTANT: Always install the factory-supplied liquid-line
filter drier. If replacing the filter drier, refer to Product Data Sheet
for appropriate part number. Obtain replacement filter driers from
your distributor or branch.
