2-4. PIPE FORMING AND DRAIN PIPING
Pipe Forming
Place the drain hose
E
elow the refrigerant piping
Make sure that the drain hose is not heaved or snaked
'
o not pull the hose when applying the tape
When the drain hose passes the room,
E
e sure to wrap insula
tion material (o
E
taina
E
le at a store) around it
2-1. FIXING OF INSTALLATION PLATE
Find a structural material (such as a stud) in the wall and
¿
x installation plate (1) horizon
tally
E
y tightening the
¿
xing screws (2)
¿
rmly
To prevent installation plate (1) from vi
E
rating,
E
e sure to install the
¿
xing screws in the
holes indicated in the illustration
For added support,
¿
xing screws may also
E
e installed
in other holes
When the knockout is removed, apply vinyl tape to the knockout edges to prevent damag
ing the wires
When
E
olts recessed in the concrete wall are to
E
e utilized, secure installation plate (1)
using 11 × 20
ā
11 × 26 oval hole (450 mm pitch)
If the recessed
E
olt is too long, change it for a shorter one availa
E
le in the market
2-2. WALL HOLE DRILLING
1)
'
etermine the wall hole position
2)
'
rill a ø65 mm hole
The outdoor side should
E
e 5 to
7 mm lower than the indoor side
3) Insert wall hole sleeve (C)
2-3. CONNECTING WIRES FOR INDOOR UNIT
<
ou can connect indoor/outdoor lead wire without removing the front panel
1) Open the front panel
2) Remove VA clamp
3) Pass indoor/outdoor unit connecting wire (A) from the
E
ack of the indoor unit and process
the end of the wire
4) Loosen terminal screw, and connect
¿
rst the earth wire, then indoor/outdoor unit con
necting wire (A) to the terminal
E
lock
%
e careful not to make mis
wiring
Fix the wire to
the terminal
E
lock securely so that no part of its core is appeared, and no external force
is conveyed to the connecting section of the terminal
E
lock
5) Firmly tighten the terminal screws to prevent them from loosening
After tightening, pull
the wires lightly to con
¿
rm that they do not move
6) Secure indoor/outdoor unit connecting wire (A) and the earth wire with the VA clamp
Never fail to hook the left claw of the VA clamp
Attach the VA clamp securely
2. INDOOR UNIT INSTALLATION
Rear, right, or downward piping
1) Put the refrigerant piping and the drain hose together, then
¿
rmly apply piping tape (G) from the end
2) Insert the piping and the drain hose into the wall hole sleeve
(C), and hook the upper part of the indoor unit on the instal
lation plate (1)
3) Check if the indoor unit is hooked securely on the installation plate (1)
E
y moving the
unit to left and right
4) Thrust the lower part of the indoor unit into the installation plate (1)
Drain Piping
If the extension drain hose has to pass through a room,
E
e sure to wrap it with commer
cially sold insulation
The drain hose should point downward for easy drain
À
ow
(Fig
1)
If the drain hose provided with the indoor unit is too short, connect it with drain hose (I)
that should
E
e provided at your site
(Fig
2)
When connecting the drain hose to the hard vinyl chloride pipe,
E
e sure to insert it securely
into the pipe

Make earth wire a little longer than others
(More than 60 mm)
'

small space
Take caution not to damage
the wires

1) Put the refrigerant piping and the drain hose together,
then
¿
rmly apply felt tape (4) from the end
Felt tape (4) overlap width should
E
e 1/3 the tape width
Use a
E
andage stopper at the end of felt tape (4)
2) Pull out the drain cap at the rear right of the indoor unit
(Fig

cap
3) Pull out the drain hose at the rear left of the indoor unit
(Fig

drain hose forward
4) Put the drain cap into the section to which the drain hose
is to
E
e attached at the rear of the indoor unit
(Fig

Insert not sharp
edged tools such as screwdrivers into
the hole at the end of the cap and insert the cap fully
into the drain pan
5) Insert the drain hose fully into the drain pan at the rear
right of the indoor unit
(Fig
4)
Check if the hose is hooked securely to the projection
of its inserting part at the drain pan
6) Insert the drain hose into wall hole sleeve (C), and hook
the upper part of indoor unit on installation plate (1)
Then, move the indoor unit completely to the left in order
to make placing the piping in the
E
ack space of the unit
easier
7) Cut out a piece of card
E
oard from the shipping
E
ox, roll
it up, hook it onto the
E
