(1) Install the drain piping.
Refrigerant pipes
Connect the drain pipe after removing the rubber cap and
insulation tubing attached to the connection hole.
• Make sure the drain works properly.
• The diameter of the drain piping should be greater than or
equal to the diameter of the connecting pipe (vinyl tube; pipe
size: 20 mm; outer dimension: 26 mm).
(not including the riser)
• Keep the drain piping short and sloping downwards at a gra-
dient of at least 1/100 to prevent air pockets from forming.
(Refer to Fig. 14)
Central drain piping
Fig. 14 (with a slope of at least 1/100)
CAUTION
Water accumulating in the drain piping can cause the
drain to clog.
• To keep the drain piping from sagging, space hanging
bracket every 1 to 1.5 m.
• Use the drain hose (2) and the metal clamp (1). Insert the
drain hose (2) fully into the drain socket and firmly tighten the
metal clamp (1) with the upper part of the tape on the hose
end. Tighten the metal clamp (1) until the screw head is less
than 4 mm from the hose. (Refer to Fig. 15, 16)
• The two areas below should be insulated because conden-
sation may form there causing water to leak.
• Drain piping passing indoors
