To prevent rainwater or other foreign bodies from entering the room and air-conditioner, the gap between wall hole
and tubing, drain pipe and electric wire should be sealed with mastic, sealant rubber or putty.
◇
If the outdoor unit is higher than indoor unit, tubing should be bent to ensure that the lowest point of the tubing is
lower than the wall hole to prevent rainwater entering the room or air-conditioner along the piping system.

Make sure that the oil can return to the unit smoothly.
◇
Horizontal pipes should incline toward the outdoor unit using a 20:1 slop.e
◇
If there is a height difference(
△
H) between the indoor and outdoor unit, oil loops should be installed in the inter
connecting gas (large) pipe;
When
△
H
≤
5 meters, an oil loop should be installed at thebottom of the gas (large) pipe;if the constant risedistance is too
long, an oil loop should be installed in the gas (large) pipe every 10 meters.
When
△
H
＞
5 meters, then for every 5 meters an oil loop mustbe installed at the bottom of the gas (large) pipe, and a short
loop (liquid ring) should be installed at theexit of the indoor unit liquid (small) pipe;
◇
When the outdoor and indoor units are at the same elevation, If the horizontal connecting pipe length is less than 10
m,the oil deposit bend and liquid ring donot need to be installed.
If the horizontal connecting pipe length is more than 10 m, install an oil loop in the gas (large)pipe every 10 metres.
