Valve Shaft Cap Tightening Torque; Service Port Cap Tightening Torque; Pump Down - Electrolux EXH09HX Installation Manual

8. Fully open the 3-way valve with hexagon
socket screw key. Turn all the way up to
contact.
9. Disconnect the gauge manifold hose
from the service port.
10. Replace the service port cap and both
valve shaft caps tightly.
• Use a gauge manifold and hoses exclusive
for R410A.
• After air removal, check the tube connec-
tions for gas leak using a leakage detector
or soapy water. Regarding leakage detec-
tor, use high-sensitivity type designed spe-
cially for R410A.
