1.Safety Precautions

Safety Precautions

Highly dangerous electrical voltages are used in this

system. Carefully refer to the wiring diagram and these

instructions when wiring. Improper connections inad-

equate grounding can cause accidental injury or death.

Ground the unit local electrical codes.

Connect all wiring tightly. Loose wiring may cause over-

heating at connection points and a possible fire hazard.

Make sure the ceiling/wall is strong enough to hold the

unit’s weight. The outdoor unit be installed in a

location where air and noise emitted by the unit will not

"sweating" that can cause dripping

and

water

damage to

walls and floors.

The outdoor unit must be installed on stable, level surface,

where there is no accumulation of snow, leaves

or rubbish.

The unit should be installed according to the instructions

in order to minimize the risk of damage from earthquakes,

Keep your fingers and clothing away from any moving parts.

Caution

Never on the place where a combustible gas might

leak

When the unit is installed at telecommunication centers or

hospitals, take a proper provision against noise.

When installing at a watery place, provide an electric leak

Do not wash the unit with water.

Be very careful about unit transportation.The unit not

i

Installing, starting up, and servicing air--conditioning equipment
can be hazardous due to system pressures, electrical components,
and equipment location (roofs, elevated structures, etc.).

Only trained, qualified installers and service mechanics should
install, start--up, and service this equipment.

Untrained personnel can perform basic maintenance functions such
as cleaning coils. All other operations should be performed by
trained service personnel.

When working on the equipment, observe precautions in the
literature and on tags, stickers, and labels attached to the
equipment.

Follow all safety codes. Wear safety glasses and work gloves. Keep
quenching cloth and fire extinguisher nearby when brazing. Use
care in handling, rigging, and setting bulky equipment.

Read these instructions thoroughly and follow all warnings or
cautions included in literature and attached to the unit. Consult
local building codes and current editions of the National Electrical
Code ( NEC ).

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 may result in minor personal injury
or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.

WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury
or death.

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.

Contact of refrigerant and fire generates poisonous gas.

Use specified refrigerant only.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment
damage or improper operation.

Never use the system compressor as a vacuum pump.

CAUTION

!

Refrigerant and indoor coil should be evacuated using the
recommended deep vacuum method of 500 microns. The alternate
triple evacuation method may be used if the procedure outlined
below is followed. Always break a vacuum with dry nitrogen.

Clear the site after installation. Make sure no foreign objects
are left in the unit.

Always ensure effective grounding for the unit.
