7. DRAIN PIPING WORK

(1) Carry out drain piping.
• Carry out drain piping so that drainage can ensured.
• Drain piping can be connected from the following directions: For right rear/right side, refer to Fig. 18 of
"6. REFRIGERANT PIPING WORK", and for left rear/left side, refer to Fig. 21.
• When conducting left rear/left side drain piping, remove the protection net. Then, remove the drain socket
cap and insulation material applied to left side drain socket and apply them to the right side drain socket.
When doing this, insert the drain socket cap all the way in to prevent a water leakage.
After the drain hose (1) (accessory) installing, attach the protection net by reversing the steps taken to
remove it. (Refer to Fig. 22)
• Select the piping diameter equal to or larger than that of the drain hose (1) (accessory) (polyvinyl chloride
piping, nominal diameter 20mm, outside diameter 26mm).
• Install the drain piping as short as possible with downward inclination of 1/100 or more and without where
air may stagnate. (Refer to Fig. 23 and 24)
(It may cause abnormal sound such as bubbling noise)
