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 with highest sales volume when connected
by 15 ft of field-supplied or factory accessory tubing. For proper
unit operation, check refrigerant charge using charging informa-
tion located on control box cover.
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.
INSTALLATION
Specifications for this unit in residential new construction market
require the outdoor unit, indoor unit, refrigerant tubing sets,
metering device, and filter drier listed in presale literature. There
can be no deviation. Consult the Application Guideline and
Service Manual—Air Conditioners and Heat Pumps Using
Puron® Refrigerant to obtain required unit changes for specific
applications and for R-22 retrofit.
