the 'restart' button on the front of the pressure controller. Open a tap, (or
garden hose nozzle) and the pump should start and deliver water. When the
tap is closed, the pump will stop once pressure is built up in the system. The
system is now working correctly.
If no water is delivered, check the troubleshooting section on Page 14 of
this manual, and additionally, refer to the pressure controller installation and
operating instructions packaged with the controller.

2. Pressure Switch
The Pressure Switch should be screwed onto the 3/4" port on the 5 way tee.
No sealing tape should be necessary and the locknut should only be just
over handtight to seal.
All pressure switches are factory set and will suit most domestic requirements
but may require further adjustment accordingly to individual installations.
3. Aqua Packs
Aqua Packs must be charged with air before installation. The air pressure used
should be 10% lower than the pressure switch cut-in setting of the pump, (e.g.
a pump working on 20-40 psi should have a tank air charge of 18 psi.)
Aqua Packs should be installed under cover, out of the weather, and the air
pressure should be regularly maintained.
4. Aqua Pack Tank Recharge Procedure
The air charge should be checked at least once a year as tanks gradually lose
air which causes pump cycling and pressure switch setting problems.
To check air pressure, turn off the electricity to the pump. Turn off the gate
valve from the water supply. Turn on a tap so that the water is drained from the
pump. Only then, measure the air pressure in the tank using a tyre pressure
gauge on the valve. If the pressure is low, recharge using a tyre pump. Do not
over charge the tank with air as this will cause tank liner damage, pressure
surge problems and/or the system to malfunction.
False readings can be obtained when checking the air pressure unless the
pressure tank is completely empty of water. If in doubt, turn off water supply,
drain discharge line and then disconnect the tank from the pipe work. When
the air pressure is correct, re-install the tank, open gate valve from the supply
tank and turn on the electricity. The pump should now operate normally once
any air is purged from the lines.
