template, make sure to follow the same direction of the holes for the roof
bolts. Fix the edges of the opening with the [-shaped aluminium bars.
•
Mount the attached suspending brackets with M8X50 expanding bolts on
the roof surface. Make sure to tighten the expanding bolts and nuts well.
The opening of the suspending brackets should face outward as shown:
•
Take the suspending poles with a nut on one end, mount them on the
fixed suspending brackets, then tighten the nuts and washers on the top
of the suspending brackets.
•
Fix the main unit onto the suspension poles with nuts and washers.
The nuts on the bottom should turn to about half of the thread length.
(Note: The above operation requires at least 2 people)

Air purging
After connecting the indoor and outdoor units, evacuate air and moisture from the refrigerant system using a vacuum
pump, as shown below.
How to purge air tubes:
•
Unscrew and remove caps from 2 and 3-way valves.
•
Unscrew and remove cap from service valve.
•
Connect vacuum pump flexible hose to the service valve.
•
Start the vacuum pump for 10-15 minutes until it reaches an absolute vacuum of 10 mm Hg.
•
With the vacuum pump still running close the low pressure knob on the vacuum pump manifold. Then stop the
vacuum pump.
•
Open the 2-way valve 1/4 turn, then close it after 10 seconds. Check tightness of all joints using liquid soap or an
electronic leak detector.
•
Turn the 2 and 3-way valves stem. Disconnect the vacuum pump flexible hose.

After evacuating the air, check for tightness of all the joints of indoor and outdoor units with a halogen detector or liquid
soap before wrapping.
Adding refrigerant:
The refrigerant volume of the models in this manual is based on using 10m connecting pipes. If your connecting pipes
are longer than 10m, additional refrigerant should be charged according to pipe length (L).
The additional refrigerant must be charged in the condition that it is running in the system. The refrigerant should be
charged to the system from the service port of the low pressure valve. Be careful not to allow air enter the system while
adding refrigerant.
IMPORTANT FOR ANY SERVICE ACTION: When charging R407C refrigerant into the system, make sure
to charge in liquid state. Otherwise, the chemical composition of the refrigerant (R407C) inside the system
may change and affect the performance of the air conditioner.
Max pipe length (m) Additional refrigerant (Kg)

Drain pipe connection
•
Connect the large end (inner diameter 25mm, outer diameter 32mm) of
the drain hose to the drain port of the main unit, then clamp it well.
•
Measure the distance from the drain pipe to the outside of wall, then cut
a Ø 25 PVC tube (inner diameter 22mm) according to this length.
•
Apply epoxy glue on the small end (outer diameter 21 mm) of the drain
hose, then connect it to the PVC tube.
•
Direct the other end of the PVC tube to the outside of the wall, connect
to a downward pipe with a Ø 25 elbow (make sure to attach the joints
well with epoxy glue).
•
If the suspended section of the indoor drain pipe exceeds 2 m, a
supporting bracket should be fitted every 1-1.5 m. The drain pipe must be
inclined downward with a gradient over 1/100 to ensure correct drain
flow. The drain pipe should not have too many bends as they may prevent
water from draining.
•
Make sure the indoor part of the drain pipe is thermally insulated.
Otherwise, condensate may form and drip on the ceiling board.
•
If the indoor section of the drain pipe is too long, proceed as described.
•
When several units drain together, proceed as described.
