i)
With the pressurised indicator extinguished and water in the external tank, the pump should be running.
Check that this is the case by operating appliances. If any appliances are calling for water let them fill until
demand ceases.
j)
Now, turn VR8 clockwise until the PRESSURISED indicator illuminates. You may turn VR8 up to 3 turns
past this point to ensure pump switch-off on pressurisation but if you turn the control too far the pump may
fail to turn on when the system de-pressurises due to demand. A reasonable overturn would be 1-2 turns
clockwise from the PRESSURISED indication point.
k)
You have now completed set-up and commissioning. Test all appliances and check to ensure that the
STATUS indicator light (RED), which may have illuminated during set-up, has now extinguished again. If the
STATUS indicator light fails to extinguish within five minutes, switch off the system and go to the
“Troubleshooting” section.
SAFETY CHECK.
Now that the system is commissioned you should check that the pump becomes disabled
when the water level in the storage tank falls to a very low (empty) level. To do this you should lift the sensor
until it is approximately 7” (18mm) below the water surface. The pump should no longer operate on demand
at this level, and the opening of the Envireau ball-cock in the header tank or any attached appliance will not
cause the pump to start. If the pump still operates at this level, you may adjust VR5 slowly anti-clockwise
until the pump turns off.
