General Information
If the drain hose cannot be sufficiently set on a slope, fit the hose with drain raising piping as shown in
the drawing.
Be sur to use the attached drain hose, drain raising pipe, clamp and drain pipe insulation
Secure a downward gradient of 1/100 or more for the drain pipe. To accomplish this, mount supporting
brackets at an interval of 1 - 1.5 m.
Use the following outline if laying central drain piping.
(Drain raising pipe laying procedure)
(1) Connect the drain raising pipe and drain hose and fasten with a clamp.
(2) Mount the drain pipe insulation and wrap with vinyl tape.
(3) After completing steps (1) and (2), attach the drain raising pipe to the drain pipe connection port of the
indoor unit and fasten with a clamp. (Do not connect any other pipes between the drain raising pipe and the
indoor unit.)
Adjust the drain raising height by turning the drain raising pipe as shown in the figure.
2. After piping, check to make sure draining flows smoothly.
If construction work for interconnecting piping is complete:
Using a plastic container for water filling, etc., gradually inject about 1,000 cc of water into the drain pan
through the inspection hatch.
Note:
To drain water from the drain pan, use the drainage port for maintenance.
