Step 2 - Installation Of The Indoor Unit - GE ASH218JCDDA Installation Instructions Manual

Installation Instructions
NOTES:
• OD unit cannot hang from a ceiling or be stacked.
• Ensure that accumulated snow, debris, etc... will not block the
air inlet or the coil exchanger if installing the OD unit with a
fence or rail guard around it.
• Ensure ventilation in case of refrigerant leakage. R-410A is a
safe, nontoxic, and nonflammable refrigerant.
• Avoid installing the OD unit where corrosive gases, such as
sulfur oxides, ammonia, and sulfurous gas are produced. If
unavoidable, consult with an installation specialist about using
a corrosion-proof or anti-rust additive to protect the unit coils.
• Do not install the outdoor unit near the edge of a balcony.
Otherwise, children may climb onto the outdoor unit and fall
off of the balcony.
• Do not install the outdoor unit in the following areas: Areas
heavily laden with oil or greasy vapors such as kitchens. Oils
and grease will create sticky layer on the coil and also cause
drainage problems, thus degrade unit performance.
• Corrosive areas that can potentially have combustible
gas leaks, contain suspended fibers or flammable dust, or
flammables such as paint thinner or gasoline can cause fires.
• Areas that contain small animals, rodents, reptiles or insects
that can infiltrate the equipment and cause damage to internal
components.
• Area where animals may urinate on the unit or ammonia may
be generated.
• Install as necessary a protective fence or the like to prevent
their access if the outdoor unit must be installed in an area
within easy reach of the general public.
• Take appropriate measures to protect it from those elements
A. Select the Indoor location:
• Do not expose the unit to unusual heat sources or steam
outlets.
• Select a location where there are no obstacles in front of
the unit.
• Make sure that condensate drainage can be conveniently
routed away.
• Do not install near a doorway.
• Ensure that the space around the left and right of the unit
is more than 4". The unit should be installed as high on the
wall as possible but allow a minimum of 4" from the ceiling.
• Use a stud finder to locate and mark stud locations for
mounting and to prevent unnecessary damage to the wall.
• Install in a location that is strong enough to withstand the
full weight and vibration of the unit.
• Leave enough space to allow access for routine
maintenance.
• Select a location that gives easy access to removing and
cleaning air filters.
• Install in a location that is 3 ft. or more away from other
electrical appliances, such as televisions and audio devices.

Step 2 - Installation of the Indoor Unit

If the outdoor unit is installed in a cold region that is affected
by snow accumulation, snow fall, or freezing. To ensure a
stable operating, install inlet and outlet ducts.
• Make sure the outdoor unit is installed level and is stable.
Install snow protection hood as necessary.
• Avoid salty places such as the seaside for installation where
air conditioner trouble is liable to occur.
• Install the outdoor unit in a location that is away from exhaust
or the vent ports that discharge vapor, soot, dust, or debris.
• Install the unit where it will not be tilted by more than 3°.
However, do not install the unit with it tilted towards the side
containing the compressor.
• When installing the outdoor unit where it may exposed to
strong wind, fasten it securely.
• It is recommended that unit be installed under a canopy or
elevated on a high stand.
• Protect the drain line from freezing in areas where
temperature drops to 32°F (0°C) or lower.
• Please set up the outdoor unit in a high place and please
do not arrange the frame of installed stand under the drain
port, because the water dropped from the drain port repeats
freezing and accumulating, and may block the drain port.
• Do not use mineral oils on flared parts. Prevent mineral oil
from entering the refrigerant system. Introduction of mineral oil
may reduce the system life.
• Be sure to use an inert gas such as nitrogen while brazing
any refrigerant lines to prevent any oxidation
• Be sure not to exceed refrigerant tubing length limits for
different models to ensure smooth operation of the unit.
Otherwise the equipment life cannot be guaranteed.
B. Install the Mounting Plate
• Remove plastic bag, tape, and mounting plate from the
back of the indoor unit.
• Place the mounting plate on the wall in the desired location
taking into account the minimum clearances necessary for
proper operation.
• Using a level, verify that the mounting plate is horizontal
and mark the screw locations.
• Attach the mounting plate to the wall with the supplied
screws.
• Wall anchors are supplied if not able to align all screw holes
with studs.
• Be sure that the mounting plate has been attached firmly
and that applied weight is evenly distributed by each
screw. (At least one screw in wall stud, others can use wall
anchors.)
• The piping for the indoor unit may be routed to and from
the unit in one of several directions: left, left rear, right, right
rear, or right below.
