4.3 Precautions when doing riser piping work

◆
Make sure that heat insulation work is executed on the following 2 spots to prevent any possible
water leakage due to dew condensation.
a) Connect the drain hose to the drain raiser pipe, and insulate them.
b) Connect the drain hose to the drain outlet on the indoor unit, and tighten it with the clamp
(take the cassette type unit for example).
◆
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 (take the cassette type unit for example).
