DRAIN PIPING WORK
CAUTION
• The connection opening on the drain piping may vary
depending on the model, so check the model name and
use the right method for that model.
• Make sure all
w
ater is out before making the duct connec-
tion.
(1) Install the drain pipin
g
.
• Make sure the drain
w
orks properly.
• The diameter of the drain piping should be greater than or
e
q
ual to the diameter of the connecting pipe (vinyl tube;
pipe size : 3/4” (19.1 mm) ; outer dimension : 1” (25.4 mm).
(not including a riser)
• Keep the drain piping short and sloping do
w
n
w
ards at a
gradient of at least 1/100 to prevent air pockets from form-
ing.
(Refer to Fi
g
. 10)
CAUTION
Water accumulatin
g
in the drain pipin
g
can cause the
drain to clo
g
.
• To keep the drain piping from sagging, space hanging
bracket every 3 to 5 feet.
• Use the drain hose (2) and the metal clamp (1). Insert the
drain hose (2) fully into the drain pipe connection hole and
firmly tighten the metal clamp (1)
w
ith the upper part of the
tape on the hose end. Tighten the metal clamp (1) until the
scre
w
head is less than 1/8 inches from the hose.
(Refer to Fi
g
. 11, 12)
• The t
w
o areas belo
w
should be insulated because conden-
sation may form there causing
w
ater to leak.
• Drain piping passing indoors
• Drain pipe connection hole
Referring the figure belo
w
, insulate the metal clamp (1) and
drain hose (2) using the included large sealing pad (5).
(Refer to Fi
g
. 12)
〈
PRECAUTIONS FOR DRAIN RAISING PIPE
〉
• Make sure the drain raising pipe height is no higher than
23-5/8 in..
• Place the drain raising pipe vertically and make sure it is no
further than 11-3/4 in. from the unit.
(Refer to Fi
g
. 13)
〈
PRECAUTIONS
〉
Drain piping connections
• Do not connect the drain piping directly to se
w
age pipes
that smell of ammonia. The ammonia in the se
w
age might
enter the indoor unit through the drain piping and corrode
the heat exchanger.
• Do not t
w
ist or bend the drain hose (2) as excessive force
causes leakage.
• If you are using central drain piping, follo
w
the procedure
outlined in the figure 10.
• Select central drain piping of proper size according to the
capacity of the connected unit.
(2) After pipin
g
work is finished, check draina
g
e flows
smoothly.
• Gradually insert approximately 2
q
uarts of
w
ater into
the drain pan to check drainage in the manner
described belo
