2- Connect the vacuum pump with theflarecouplingof
the outdoor unit equipped with a process valve (large
coupling).
3- Start the vacuum pump and check that the needle of
the indicator goes down to -0,1 Mpa (-76 cm Hg).
Thepump shouldrunduring atleast15 minutes.
4 - Before disconnecting the vacuum pump, check that
thevacuumindicator remainsinthesamepositionduring
fiveminutes.
5- Disconnect the vacuum pump andclosetheprocess
valve.
6-Removethecapofthe"GAS"and"LIQUID"valvesand
open them with a hexagonal wrench to free the
R407C containedin the outdoorunit.Putthe caps back.
7 - Check that the linking pipes are sealed. Use an
electronicleak detectorora soapy sponge.
ADJUSTMENT OF THE CHARGE
Adjustmentof the chargemaybeneeded depending on
thelength ofthe linking pipesand ontheindoor unit.
This operation should be done expertly by qualified
personnel and (regrigeration engineer). The additional
charge is to be added through the process valve of the
flarecoupling of theoutdooorunit(large coupling).
Anyactiononthe coolingcircuits requirestocomplywith
theCECOMAF GT1-001 recommendations.(relatedto
thedischarge ofR407C intotheatmosphere).
