5.0 INSTALLATION
1. Fasten meter assembly to the wall using suitable fixings.
2. Flush water feeds to ensure only clean water is used and no debris from pipe installation
is present.
3. Connect the supply pipes (22mm diameter) with the hot water to the left and the cold
water to the right.
4. Turn on the water, without setting the meter, to pressurise the piping and check for leaks.
5. Operate the meter into a bucket a few times to flush the system and ensure that all
pipeing is clean.
MINIMUM WATER PRESSURE REQUIRED
0.1bar
MAXIMUM WATER PRESSURE
6.0 bar
MAXIMUM PUMPED WATER PRESSURE

Note

For best results, the meter should be positioned above a drain to allow for priming
of the meter at start up.

HOT AND COLD WATER SUPPLIES MUST BE OF EQUAL PRESSURE.
This can be achieved by having the hot and cold supply pressurised from the
same header tank or having header tanks at equal heights.
Alternatively a pressure-reducing valve can be fitted to the cold supply.

A water-softening unit must be fitted to both supplies in hard water areas.
Mono can advise on this matter.
