11. CONNECT THE DRAIN PIPE
Install the drainpipe of the indoor unit
Use a polyethylene tube as the drainpipe (out-dia.29-31mm
/1.14-1.22in, in-dia.25mm/0.984in). It could be bought from
the local market.
When extending drainpipe,tighten the connector with
water-proof tape to prevent it leakage.
Please lean the drainpipe down toward outdoor (outlet-side)
at a degree of over 1/ 50 to avoid water flowing back. And
please avoid any bulge.
Do not drag the drainpipe violently. Meanwhile, one
supportpoint should be set every 1~1.5m/3.28~4.92ft to
prevent the drainpipe from yielding. Or tie the drainpipe with
the connecting pipe to fix it.
If the outlet of the drainpipe is higher than the body's pump
joint, the pipe should be arranged as vertically as possible.
And the lift distance must be less than 550mm/21.65in,
otherwise the water can not be lifted completely and cause
overflow.(Only available for the unit with pump.)
The end of the drainpipe should be over 50mm/1.969in higher
than the ground , and do not immerse it in water. If you
discharge the water directly into sewage, be sure to make a
U-form aquaseal by bending the pipe up to prevent the smelly
gas entering the house through the drain pipe.
Loosen and remove the nuts of service valves A and B,
and connect the charge hose of the manifold valve with
the maintenance terminator of service valve A. (Be sure
that service valves A and B are both closed)
Connect the joint of the charge hose with the vacuum
pump.
Open the Lo-lever of the manifold valve completely.
Turn on the vacuum pump. At the beginning of pumping,
loosen the nut of service valve B a little to check whether
the air comes in (the sound of the pump changes, and
the indicator of compound meter turns below zero). Then
fasten the nut.
