Drill A Hole In The Wall - INVENTOR AR2MVI32-12WiFi/AR2MVO32-12 Instruction Manual

INDOOR UNIT INSTALLATION

2. Drill a hole in the wall

1. Determine hole positions according to left
and right side of the installation plate. The hole
center is obtained by measuring the distance as
shown in the diagram of Fig.2.

2. Dirll the piping plate hole with 65mm hole-core drill.
3. Drill the piping hole at either the right or the left and
the hole should be slightly slanted to the outdoor side,
so that the outside end is lower than inside end,see Fig.3.
4. Always take steps to protect the pipe when drilling
metal grid,metal plate or the like.
3. Connective pipe installation
1. For the left-hand and right-hand piping,
remove the pipe cover from the side panel.
2. For the right back and left back piping,
install the piping as shown.
NOTE: Both sides drainage structure is
standard. For both sides drainage structure,
it can be choosen for right, left or both sides
drainage connection. If choosing both sides
drainage connection, another proper drain
hose is needed as there is only one drain
hose offered by factory. If choosing one side
drainage connection, make sure the drain
hole on the other side is well plugged.
For 9k/12k models, if choosing left-hand
or left-back piping,please choosing left side
drainage connection. The connection of the
drain hose is supposed to be done by
qualified installer in case of water leakage.
3. Attach the drain hose to the underside of
the refrigerant pipes with adhesive viny
tape.
4. Wrap the refrigerant pipes and drain hose
together with insulation tape.
5. Open the front panel, then open the wire
cover, connecting the cables.
6. Bundle the pipes, connecting cable, and
drain hose with tape securely, evenly as
shown in Figure on the right.
7. Pass them through the wall hole.
Because the condensed water from rear
of the indoor unit is gathered in ponding
box and is piped out of room. Do not put
anything else in the box.

CAUTION
Connect the indoor unit first, then the outdoor unit.
Do not allow the piping to let out from the back of the indoor unit.
Be careful not to let the drain hose slack.
Heat insulation should be done to the extension drain hose of indoor unit.
Be sure that the drain hose is located at the lowest side of the bundle. Locating at the upper
side can cause drain pan to overflow inside the unit.
Never intercross nor intertwist the power wire with any other wiring.
4.Drain piping
1. Connect the drain hose as described
in Fig.6. The drain hose should be
inclined downward.
2. When drain hose requires extension,
obtain an extension hose commercially
available. Be sure to thermally insulate
the indoor section of the extension
hose. Do not let the drain hose slack.
3. Remove the air filter and pour some
water into the drain pan to check
the water flows smoothly.
5. Connect the cable to the indoor unit

Electric safety regulations for the initial Installation
1. If there is serious safety problem about the power supply, the technicians should refuse to
install the air conditioner and explain to the client until the problem is solved.
2. Power voltage should be in the range of 90%~110%of rated voltage.
3. The surge protector and main power switch with a 1.5 times capacity of Max. Current of the unit
should be installed in power circuit. Ensure the air conditioner is grounded well.
4. The appliance shall be installed in accordance with national wiring regulations.
your air conditioner in a wet room such as a bathroom or laundry room.
5. An all-pole disconnection device which has at least 3mm clearances in all poles, and have a
leakage current that may exceed 10mA, the residual current device(RCD) having a rated
residual operating current not exceeding 30mA, and disconnection must be incorporated in the
fixed wiring in accordance with the wiring rules.
6. For the unit adopts auxiliary electric heater, keep at least 1 meter away from the nearest
combustible materials.
7. According to the attached Electrical Connection Diagram located on the panel of the indoor &
outdoor unit to connect the wire.
8. All wiring must comply with local and national electrical codes and be installed by qualified and
skilled electricians.
9. Every wire must be connected firmly. No wire should be allowed to touch refrigerant tubing,
the compressor, or any moving parts.
10. Loose wiring may cause the terminal to overheat or result in unit malfunction. A fire hazard
may also exist. Therefore, be sure all wiring is tightly connected.
9. An individual branch circuit and single receptacle used only for this air conditioner must be
available. See the following table for suggested wire sizes and fuse specifications:
