8. CONNECT THE DRAIN PIPE
Install the drainpipe of the indoor unit
The outlet has PTI screw bread, Please use sealing materials
and pipe sheath(fitting) when connecting PVC pipes.
The drain pipe of indoor unit must be heat insulated, or it will
condense dew, as well as the connections of the indoor unit.
Hard PVC binder must be used for pipe connection, and make
sure there is no leakage.
With the connection part to the indoor unit, please be noted not
to impose pressure on the side of indoor unit pipes.
When the declivity of the drain pipe downwards is over 1/100,
there should not be any winding.
The total length of the drain pipe when pulled out traversely shall
not exceed 20m, when the pipe is over long, a prop stand must
be installed to prevent winding.
Refer to the under figures for the installation of the pipes.

Additional Refrigerant Charge
7.2
CAUTION
Refrigerant cannot be charged until field wiring has been
completed.
Refrigerant may only be charged after performing the leak test
and the vacuum pumping.
When charging a system, care shall be taken that its maximum
permissible charge is never exceeded, in view of the danger of
liquid hammer.
Charging with an unsuitable substance may cause explosions
and accidents, so always ensure that the appropriate
refrigerant is charged.
Refrigerant containers shall be opened slowly.
Always use protective gloves and protect your eyes when
charging refrigerant.
The outdoor unit is factory charged with refrigerant.
Calculate the added refrigerant according to the diameter
and the length of the liquid side pipe of the outdoor
unit/indoor unit connection.
NOTE:The number of bends is up to the length of the max
height drop.Usually for each 10m need a bend.
