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 the signal words DANGER, WARNING, and CAU-
TION. These words are used with the safety-alert symbol. DAN-
GER 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

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® (R-410A) systems operate at higher
pressures than standard R-22 systems. Be certain that
service equipment is rated for R-410A. Some R-22
service equipment may not be acceptable. Check with
your distributor.
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
indoor unit of the same size when connected by 15 ft of
field-supplied or factory accessory tubing. For proper unit opera-
tion, check refrigerant charge using charging information located
on control box cover or in the Check Charge section of this
instruction.
IMPORTANT: Maximum liquid-line size is 3/8–in O.D. for all
residential applications.
IMPORTANT: Always install the factory-supplied Puron® heat
pump (bi-flow) liquid line filter drier. Obtain replacement filter
driers from your distributor or branch.
