• After checking for gas leaks, be sure to insulate the pipe connections using the thermal insulation tube
& finishing tape. The finishing tape should be wrapped from the L-shaped bend all the way to the inside
the unit (Refer to fig.15)
CAUTION
Be sure to insulate any field piping all the way to the piping connection inside the unit. Any exposed piping
may cause condensation or burns if touched.
6. DRAIN PIPING WORK
(1) Install the drain piping. (Refer to Fig. 16)
• The drain pipe should be short with a downward slope and should prevent air pockets from forming.
• Watch out for the points in the Fig. 16 when performing drain work.
• When extending the drain hose, use a commercially available drain extension hose, and be sure to
insulate the extended section of the drain hose which is indoors. (Refer to Fig. 17)
• Make sure the diameter of the piping is the same as the piping (hard vinyl chloride, nominal diameter
13mm) or bigger.
