Before Installation
1. Before installation, please check whether the valve head has come loose from the tank.
2. Open the upper cover by pulling up and then disconnecting the cable running to the electronic display.
3. Remove the three screws at the back of the unit and remove the rear cover.
4. Check the valve head for movement relative to the tank. If the valve head is loose, turn clockwise to tighten. Confi rm that the
O-ring is not pinched between the tank and valve head.
NOTE:
This might require two people: one to hold the tank and another to turn the valve head.
NOTE:
The gap between the tank and valve head should be smaller the 0.5mm.
5. Re-install the rear cover using only the two lower screws. The upper screw is only used for shipping and should be discarded.
NOTE:
Do not re-install the top cover at this time.
