When the system is installed and operates in a small room, it is required
to maintain the concentration of the refrigerant below the limit, in case a
leak occurs. Otherwise, oxygen in the room may be affected, resulting in
a serious accident.
The refrigerant in the air conditioner is safe and normally does not leak.
If the refrigerant leaks into the room and comes into contact with the fire
of a burner, a heater or a cooker, a harmful gas could be released. Turn
off any combustible heating devices, ventilate the room, and contact the
dealer where you purchased the unit.
Do not use the air conditioner until a service person confirms that the
refrigerant leak is repaired.
Keep ventilation openings clear of obstruction.
Installation
Check Equipment
Unpack unit and move to final location. Remove carton, taking care not
to damage unit. Remove protective sheet metal from the base of the unit,
if equipped. Inspect equipment for damage prior to installation. File
claim with shipping company if shipment is damaged or incomplete.
Locate rating plate on unit. It contains information needed to properly
install unit. Check rating plate to be sure unit matches job specifications.
A front access panel is provided, which permits access to blower
assembly and electrical controls for removal and servicing.
NOTE: For models that are pre-installed with electric heater, the
protective isolation cover of the air outlet must be removed before
installing the air outlet duct system.
A240386
NOTE: Minimum clearance of 21" (533 mm) is required in front of
access panel for servicing only. Installation clearance from combustible
materials is 0" (0 mm) from cabinet and supply-air duct (plenum
included). Make sure there is adequate space on top of unit for
refrigerant line connections and on bottom of unit for condensate trap
(Fig. 2 and Fig. 3).
PERSONAL INJURY / PROPERTY DAMAGE HAZARD
Be sure the air conditioner is grounded.In order to avoid electric shock,
make sure that the unit is grounded and that the earth wire is not
connected to a gas or water pipe, lightning conductor or telephone earth
wire.
Do not operate the air conditioner with a wet hands. An electric shock
may happen.
Do not touch the heat exchanger fins. These fins are sharp and could cut
you.
To avoid oxygen deficiency, ventilate the room sufficiently if
equipment with a burner is used together with the air conditioner.
Arrange the drain hose to ensure smooth drainage. Incomplete
drainage may cause wetting of the building, furniture, etc.
Never touch the internal parts of the controller.
Do not remove the front panel. Some parts inside are dangerous to
touch, and machine troubles may occur.
Attention is drawn to the fact that additional transportation regulations
may exist with respect to equipment containing flammable gas. The
maximum number of pieces of equipment or the configuration of the
equipment permitted to be transported together will be determined by
the applicable transport regulations.
Signs for similar appliances used in a work area are generally addressed
by local regulations and give the minimum requirements for the
provision of safety and/or health signs for a work location. Storage
package protection should be constructed such a way that mechanical
damage to the equipment inside the package will not cause a leak of the
REFRIGERANT CHARGE.
The maximum number of pieces of equipment permitted to be stored
together will be determined by local regulations.
Do not operate the air conditioner when using a room fumigation type
insecticide.
Failure to observe this precaution could cause the chemicals to become
deposited in the unit, which could endanger the health of those who are
hypersensitive to chemicals.
Do not place appliances which produce open flame in places exposed to
the air flow from the unit or under the indoor unit. It may cause in
complete combustion or deformation of the unit due to the heat. Do not
install the air conditioner in a location where flammable gas may leak
out. If the gas leaks out and stays around the air conditioner, a fire may
break out.
ELECTRICAL OPERATION HAZARD
Failure to maintain proper clearances could result in personal injury or
death.
Before installing or servicing unit, always turn off all power to unit.
There may be more than 1 disconnect switch. Turn off accessory heater
power if applicable.
CUT HAZARD
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care and wear
appropriate protective clothing, safety glasses and gloves when
handling parts.
HOT TUBE WARNING
Failure to follow this caution could result in personal injury and/or
property damage.
Refrigerant lines can reach or exceed 130 °F (54 °C). Avoid contact
with the vapor header or vapor line, especially in Heating Mode. Do not
service A2L refrigerant fan coils while these components are hot to
avoid risk of ignition source.
Remove these screws
first, and then remove the
protective isolation cover.
