Step 12 Evacuating The Air; Step 13 Charging The Refrigerant - Samsung AC100KXADEH Installation Manual

Installation Procedure
1 Connect the charging hose of low pressure side of
manifold gauge to the packed valve having a service
port as shown at the figure.
NOTE
∙ The designs and shape are subject to change
according to the model.
2 Open the valve of the low pressure side (A) of the
manifold gauge anticlockwise.
3 Connect the manifold gauge to the nitrogen gas.
4 Apply nitrogen gas.
5 Check the change of pressure with a pressure
regulator.
6 Check the gas leakage at the connection part or
brazed part by using soap water.
7 Open the manifold gauge to discharge nitrogen.

Step 12 Evacuating the air

1 Connect the manifold gauge to a vacuum pump.
2 Purge the air from the system using the vacuum
pump for about 30 minutes.
∙ Make sure that pressure gauge shows -0.1006 Mpa
after about 30 minutes.
∙ Use a vacuum pump that is at least 140 l/min in
capacity.
∙ Make sure that vacuuming timing is longer when
the piping gets longer.
∙ Pressure will not drop even after 5 minutes of
vacuuming when there is moisture within the pipe.
In this case, apply nitrogen gas again, and then
purge the air again.

Step 13 Charging the refrigerant

Important information regulation regarding the
refrigerant used
This product contains fluorinated greenhouse gases. Do
not vent gases into the atmosphere.
CAUTION
∙ Inform user if system contains 5 tCO
fluorinated greenhouse gases. In this case, it has to be
checked for leakage at least once every 12 months,
according to regulation n° 517/2014. This activity
has to be covered by qualified personnel only. In case
situation above (5 tCO e or more of R-410A), installer
2
(or recognised person which has responsability for
final check) has to provide a maintenance book,
with all the information recorded according to
REGULATION (EU) N° 517/2014 OF THE EUROPEAN
PARLIAMENT AND OF THE COUNCIL of 16 April 2014
on certain fluorinated greenhouse gases.
Please fill in the following with indelible ink on the
