16) Set-up and commissioning. It is essential that these instructions are carried out before

leaving the system with electrical power applied.

a) First of all, determine approximately the level of water in the storage tank i.e. Full, Half-full, etc. and

conﬁrm that the depth sensor is out of the water. Now TURN OFF the stop-cock on the pump incoming

line before the in-line ﬁlter.

b) Apply power to the system and observe the display unit. The pointer on the display level indicator

should read empty. (If it does not, investigate the connections to the depth sensor.)

c) Now lower the depth sensor into the tank and allow it to rest on the bottom. Observe the display level

indicator again. The pointer will read either a “level” or will show a “fan-like” effect of ﬂashing pointers.

d) You must now remove the lid of the controller and identify the setting controls along the bottom of the

Printed Circuit Board. You must set the LEVEL indication using VR2.

e) To adjust the level display turn the small brass set-screw of VR2 CLOCKWISE to LOWER the reading,

ANTI-CLOCKWISE to RAISE the reading. Note. If the Level Indicator is showing FLASHING pointers this is

a HIGH reading (See “Troubleshooting”) and so you should turn VR2 clockwise. Set the display to

approximate to the actual water level in the tank.

f) Now remove the ﬁlter from the in-line ﬁlter carrier on the pump incoming pipe and VERY SLOWLY open

the incoming stop-cock below the ﬁlter carrier. You will hear air rushing up the pipe from the pump. Be

ready to turn off the stop-cock to avoid spillage from the ﬁlter carrier. Turn off the stop-cock when water

wells up inside the ﬁlter carrier. Replace the ﬁlter and screw the parts together ﬁrmly. NOW OPEN THE

STOP-COCK FULLY. Check for leaks.

g) Observe the display unit. The STATUS light may be illuminated. Ignore this indication during setting up.

You must now set the PRESSURE switch point using VR8.

h) To set VR8, the pressurized indicator must ﬁrst of all be extinguished. To do this you will now set the

PUMP SWITCH-OFF pressure to a higher pressure than the pump can achieve. The pressurized indicator

is the GREEN light nearest to VR8. TURN VR8 ANTI-CLOCKWISE UNTIL THE PRESSURISED INDICATOR

EXTINGUISHES. If it is already unlit at initial observation then proceed to (i) below.

i) With the pressurized indicator extinguished and water in the external tank, the pump should be running.

Check that this is the case by operating the ball-cock in the header tank or by operating any other

appliances on the same feed (e.g. external taps). Allow the header tank to FILL and the DEMAND

to cease.

j) NOW, turn VR8 clockwise until the pressurized indicator illuminates. You may turn VR8 up to 3 turns

past this point to ensure pump switch-off on pressurization but if you turn the control too far the

pump may fail to turn on when the system de-pressurizes due to demand. A reasonable overturn would

be 1-2 turns clockwise from the pressurized indication point.

k) You have now completed set-up and commissioning. Test all appliances and check to ensure that the

STATUS indicator light, 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 ENVIREAU ball-cock in the header tank

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.
