employed that come into contact with the fluid are adequately resistant.

INSTALLATION
Installation must be undertaken by a qualified technician and to good engineering practice. In addition,
users attention is drawn to our joint responsibility to ensure that the health and safety at work act is not
contravened by incorrect installation, commissioning or servicing.
Fitting Gauge to Tank:
1. Ensure that the tank flanges are vertically in line with each other and that the flange faces are
parallel to the tank wall. Make sure that there are no obstructions between the gauge and tank
flange faces.
2. Fit suitable gaskets between gauge and tank flange and secure flanges together using suitable
nuts, bolts and washers. Make sure column is in no way strained, then tighten bolts.
3. The gauge is supplied in a single section up to 1000mm. Longer columns are supplied, in
general, with intermediate supports, which divide the column into sections, each not exceeding
1000mm. A suitable support pad will be required on the tank, to fix the support bracket.
4. Open valves and check gauge for leaks. Rectify any leaks in accordance with maintenance
information instructions.
OPERATING INSTRUCTIONS
To Open Gauge:
1. Open top valve fully (if fitted).
2. Open bottom valve slowly until fully open (to prevent auto safety valve snapping shut). If auto
safety valve does close off flow of liquid into column, close isolating valve fully and then open
approximately half a turn to allow liquid to find its own level, then open fully.
To Close Gauge:
1. Close isolating valves fully.
To Drain Gauge:
1. Close isolating valves fully.
2. Open drain valve or unscrew drain plug. Protect hands from flow of liquid.
3. Close drain valve or replace drain plug immediately after draining.
