Ins alla ion Procedure
2. Selec ion of he place of ins alla ion
1. Accessories
"Edging" for protection of electric wires from an
opening edge.
Select the place of installation satisfying the following conditions and, at the
same time, obtain a consent from the client or user.
Edging
Place where air circulates.
Place free from heat radiation from other heat sources.
Place where drain water may be discharged.
Place where noise and hot air may not disturb the neighborhood.
Place where there is not heavy snowfall in the winter time.
Place where obstacles do not exist near the air inlet and air outlet .
Place where the air outlet may not be exposed to a strong wind.
Place surrounded at four sides are not suitable for installation. A 1m or more
of overhead space is needed for the unit.
Mount guide-louvers to place where short-circuit is a possibility.
When installing several units, secure sufficient suction space to avoid short
circuiting.
Wind direction
NO
(2) Ins alla ion where he area wi h s rong winds.

Precautions for refrigerant piping
Do not twist or crush piping.
Be sure that no dust is mixed in piping.
Bend piping with as wide angle as possible.
Keep insulating both gas and liquid piping.
Check flare-connected area for gas leakage.
Connecting method (indoor unit)
Apply refrigerant oil at half union as large and flare nut.
To bend a pipe, give the roundness as possible not to crush
the pipe.
When connecting pipe, hold the pipe centre to centre then
screw nut on by hand, refer to Fig.
Be careful not to let foreign matters, such as sands enter
the pipe.
(4) Piping connec ion
Forced fastening without centering
may damage the threads and cause a
gas leakage.

In the first to third test steps, if the pressure drops, check the leakage in each joint

After finishing connection of refrigerant pipe, it shall perform air tightness test.
The air tightness test adopts nitrogen tank to give pressure according to the pipe connection
mode as the following figure shown.
The gas and liquid valve are all in close state. In order to prevent the nitrogen entering the
circulation system of outdoor unit, tighten the valve rod before giving pressure (both gas
and liquid valve rods).

It shall use the vacuum pump of (lower than -755mmHg)high vacuum degree and large air
discharging (over 40l/min).
The vacuumizing time depends on the length of the connecting pipe, generally is 1~2 hours.
When vacuumizing, it shall be confirmed both gas and liquid side valves are closed.
If after 2 hours vacuumizing, it cannot reach the vacuum degree below -755mmHg, it can be
vacuumized for other 1 hour.
If after 3 hours vacuumizing, it still cannot reach the vacuum degree below -755mmHg, check
if there is any leaking point and repair the them.
If after over 2 hours vacuumizing, the vacuum degree is below -755mmHg, close the VL
and VH on the meter separator and stop vacuumizing. 1 hour later to confirm if the vacuum
degree changes. If changes, it indicates there is leaking point in the system. Check the leaking
point and repair.
After finishing the above vacuumizing, change the vacuum pump into refrigerant pump to
charge the refrigerant.
se vacuum pump to perform vacuumizing. It is strictly forbidden to use the
refrigerant to remove the air inside the system.
After air tightness test and discharging all the nitrogen, connect the vacuum pump
as the following figure shown.

When the total length (L) of the two units' connecting pipe is less than 5m, it is
unnecessary to charge additional refrigerant.
If the connecting pipe (L) exceeds 5m, it shall charge Mg additional refrigerant per meter.
That is: Refrigerant charging amount = (L-5) x M (g)

Only in COOLING operation can charge the additional refrigerant.
When charging, the refrigerant shall be charged from the charging nozzle of low pressure vavle.
Be carefull when charging refrigerant, do not let the air mix into the system,and must charge the
additional refrigerant in liquid condition.
