- Remove the protective plug (B) from the lling hole
(Schrader) in the gas valve (large diameter).
- Connect the high pressure hose from the Manifold to
the lling hole (gure 24).
- Connect the nitrogen bottle to the Manifold (only use
dehydrated nitrogen type U).
- Fill the refrigeration circuit with nitrogen to maximum
10 bar (gas-condenser-liquid connection system).
- Maintain this pressure in the circuit for 30 minutes.

- If a pressure drop occurs, bring it back down to 1 bar
and look for leaks with a leak detector, repair and
repeat the test.

- Once the pressure is steady and there are no leaks,
empty the nitrogen by leaving the pressure above
atmospheric pressure (between 0.2 and 0.4 bar).
3.4.2 Creating a vacuum
The triple evacuation method (APPENDIX 2)
is strongly recommended for any installation and
especially when the outdoor temperature is
below 10°C.
- If necessary, calibrate the Manifold pressure gauge(s)
to 0 bar. Adjust the vacuum gauge to current
atmospheric pressure (≈ 1013 mbar).
- Connect the vacuum pump to the Manifold. Connect
a vacuum gauge if the vacuum pump is not equipped
with one.

- Create a vacuum until the residual pressure* in the
circuit falls below the value given in the following
table (* measured with the vacuum gauge).

- Let the pump continue to operate for another 30
minutes minimum after reaching the required vacuum.
- Close the Manifold valve, then stop the vacuum pump
without disconnecting any of the hoses in place.
