Seaside applications and installation
Seaside applications and installation
1.
Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are produced.
2. Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result corrosion
on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient performance.
3.
If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind.
Selecting the location(Outdoor Unit)
1) If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided.
Install the outdoor unit on the opposite side of the sea wind direction.
Sea wind Sea wind
2) To
install the outdoor unit on the seaside, set up a windbreaker/barrier to keep the unit from being exposed to
the sea wind.
Windbreaker/Barrier
Sea wind
3) Select a well-drained place.
• It should be strong enough (like concrete) to
obstruct the wind from the sea.
• The height and width should be more than 150% of
the outdoor unit.
A minimum of 70cm (27.6inches) of space between
•
outdoor unit and the windbreaker/barrier for easy
air flow.
1. Periodic ( more than once/year ) cleaning of dust or salt particles stuck on the heat exchanger using water is recommended.

Installing Installation Plate(Standard Type)
The wall you select should be strong and solid enough to
prevent vibration
1. Mount the installation plate on the wall with
type "A" screws. If mounting the unit on a concrete wall,
use anchor bolts.
• Mount the installation plate horizontally by aligning the
centerline using a level.
2. Measure the wall and mark the centerline. It is also
important to use caution regarding the location of the
installation plate, as routing the wiring through the wall is
typically done in this application. Drilling the hole through
the wall for piping connections must be done safely.

Flaring Work and Connection of Piping
Flaring work
The main cause for gas leakage is due to defects in flaring work. Carry out correct flaring work using the following procedures.
Cut the pipes
1. Use the copper pipe purchased locally.
2. Measure the distance between the indoor and the outdoor unit.
3. Cut the pipes a little longer than measured distance.
4. Cut the cable 1.5m (5.0ft) longer than the pipe length.
Burrs removal
1. Completely remove all burrs from the cut cross section of
pipe/tube.
2. Put the end of the copper tube/pipe in a downward direction
as you remove burrs in order to avoid dropping burrs into the
tubing.
Pipe
Reamer
Adding the Flare Nut
• Remove flare nuts attached to the indoor and outdoor unit,
then put them on the end of the copper pipe once you hav
completed burr removal (it is not possible to put them on after
the flaring work)
Flaring work
• Carry out flaring work using flaring tool as shown below.
• Firmly hold copper pipe in the proper size hole dimension of
the bar as shown in the table below.

Check
1. Compare the flare work like the figure on the right.
2. If a flared section is defective, cut it off and repeat the flaring process again.
Connecting the Piping
Indoor
1. Prepare the indoor unit's piping and drain hose for installation through the wall.
2.
Remove the plastic tubing retainer(see illustration on the
right) and pull the tubing and drain hose away from chassis.
For right rear piping
1. Route the indoor tubing and the drain hose in the direction
of rear right.
2.
Insert the connecting cable into the indoor unit from the outdoor unit through the piping hole.
• Do not connect the cable to the indoor unit.
•
Make a small loop with the cable for easy connection later.
3. Tape the tubing, drain hose, and the connecting cable. Be
sure that the drain hose is located on the lowest side of the
bundle. Locating on the Upper side can cause the condensation to overflow in the drain pan inside the indoor unit.
If the drain hose is routed inside the room, insulate the hose
with an insulation material* so that dripping from "sweating"(condensation) will not damage furniture or floors.
*Foamed polyethylene or equivalent is recommended.

Hook the indoor unit onto the upper portion of the installation plate.(Engage the two hooks of the rear top of the
indoor unit with the upper edge of the installation plate.)
Ensure that the hooks are properly seated on the installation plate by moving the indoor unit left and right.
Press the lower left and right sides of the unit against the
installation plate until the hooks engage into their
slots(clicking sound).
Connecting the piping to the indoor unit and drain hose
to drain pipe.
1. Align the center of the pipes and sufficiently tighten the
flare nut by hand.
2. Tighten the flare nut with a torque.

Then attach the drain pipe.
Wrap the insulation material around the all connections.
1. Overlap the connection pipe insulation material and the
indoor unit pipe insulation material. Bind them together
with vinyl tape so that there is no gap.
2. Wrap the area which accommodates the rear piping housing section with vinyl tape.
3. Bundle the piping and drain hose together by wrapping
them with vinyl tape, enough to cover where they fit into
the rear piping housing section.

1. Route the indoor tubing and the drain hose to the required
piping hole position.
2. Insert the piping, drain hose, and the connecting cable into
the piping hole.
3.
Insert the connecting cable into the indoor unit.
• Don't connect the cable to the indoor unit.
• Make a small loop with the cable for easy connection
later.
4. Tape the drain hose and the connecting cables.
5. Indoor unit installation
• Hang the indoor unit from the hooks at the top of the
installation plate.
• Insert the spacer. between the indoor unit and the instal-
lation plate to separate the bottom of the indoor unit from
the wall. (The spacer is used to ease installation and will
be removed later on per the installation instructions.)
