6. Discharge gas by slowly releasing the blowdown valve until the gas
pressure is the value shown in
table 9-9 “Adequate Gas Pressure per
Gas Balancer Surface Temperature”
7. Close the needle valve and blowdown valve, and then remove the gas
filling device from the quick connector.
8. Remove the quick connector and mount the cover, then tighten the
hexagon socket head screw plug M6 with flange by using a tightening
torque of 4.9 N•m (0.5 kgf•m).
9. Mount the cover and tighten the hexagon socket head cap screws M4
(length: 6mm) with a tightening torque of 2.8 N•m (0.29 kgf•m.)
10. Turn ON the power supply of the DX200.
