•
Drill 6 mm dia x 40 mm deep holes. Fix the mounting plate (with sensor) using the two fasteners
supplied with the plate. Epoxy fixed threaded anchors can also be used, if required
NOTE:
It is very important that the sensor body is kept absolutely vertical while in operation. A tilted
sensor will give erratic readings. Use a small spirit level (preferably bubble type). Adjust the
fasteners so that the spirit level shows a perfect alignment.
4.3 Installation of reservoir & moisture trap
•
Mark the location of the four holes for drilling. Drill 8 mm dia x 70 mm deep holes. Fix the mounting
plates (with the reservoir) using the four fasteners provided in the supply.
•
Mark the four holes for the moisture trap. Moisture trap is mounting in vertical position, with hydrophobic
filter at the bottom. Location of moisture trap must be little above the top of reservoir (figure 4-6). Drill
6 mm dia x 50 mm deep holes. Fix the moisture trap using the four fasteners provided in supply.
•
Connect the moisture trap to the reservoir with the desired length of 8 mm od air vent tube. Suitable
quick connectors are provided on reservoir as well as on the moisture trap. Remove the plug from the
quick connector of the moisture trap before connecting the air vent tube.
•
Close the isolation valve of the reservoir.

4.4 Installation of pressure gage and valve assembly
Mark the location of the four holes for drilling. Drill 6 mm dia x 40 mm deep holes. Fix the mounting plates
(with the gage and valves) using the four fasteners provided in the supply. Ensure that the zero of the gage
is towards bottom side.
