WARNING!
WARNINGS ARE GIVEN WHERE FAILING TO OBSERVE THE INSTRUCTION COULD RESULT IN INJURY.
CAUTION!
CAUTIONS ARE GIVEN WHERE FAILURE TO OBSERVE THE INSTRUCTION COULD RESULT IN DAMAGE TO THE EQUIPMENT, ASSOCIATED EQUIPMENT AND PROCESSES.
PRINCIPLE OF OPERATION
2.1
Feed water is passed via the inlet valve into the purification cartridge and through the ion exchange bed where it is deionised. The purity of the water is measured before exiting from the deionised water outlet.
2.2
The purity of the water is checked manually. For procedure see OPERATION section.
2.3
When the water purity declines and is continuously in the RED zone the purification cartridge should be replaced.

INSTALLATION AND OPERATION MANUAL Micromeg S & E 4
Reference Number: MANU30362
Installation
4.1
Ideally the unit should be positioned over a sink or drain and adjacent to a suitable cold potable feed water supply. Sufficient clearance should be allowed under the deionised water outlet to accommodate normally used containers.
4.2
Fit No 8 x ½” long wood screws and hang Micromeg unit onto screw. With the unit positioned horizontally mark position of the remaining fixing holes and fit screws to secure unit firmly to wall.
4.3
Connect feed water supply to Micromeg inlet valve using ½” diameter bore reinforced hose and secure.
4.4
Fit battery to red snap connector and insert battery into compartment taking care to position the batteries behind the removal pull out strap. Check meter operation by raising the Test Switch. The battery condition will be indicated on the upper meter scale. The battery condition is satisfactory when the upper meter registers in the GREEN zone.
Note: 4.5
The Test Switch is a spring return type and has to be held in the position required to obtain a reading. Screw deionised water outlet assembly to the outlet spigot housing (located on the underside of the Micromeg unit).
Note: Do NOT tighten the spigot retaining unit. The water seal is achieved by ‘O’ rings and does not require the retaining nut to be tightened. 4.6
Remove transit cap from purification cartridge base and screw the cartridge onto the Micromeg until positive resistance is felt. The text on the cartridge should be correctly orientated.
4.7
Remove transit cap from the top of the purification cartridge and fit inlet hose connector.
CAUTION!
Isolate the feed water supply if the unit is not in regular use (e.g. overnight and weekends). Protect from frost.

OPERATION
5.1
Ensure feed water supply is on.
5.2
Open Micromeg unit inlet valve by turning the black knob anti-clockwise, after a short delay, water will flow from the deionised water outlet.
Note: 5.3
Note:
The initial flow will be intermittent until the residual air is expelled from the cartridge. Determine the deionised water purity by depressing the Test Switch and observing the indicated water purity on the lower meter scale. Water is of acceptable purity when the lower meter registers in the GREEN zone. Initially the meter may register in the RED zone indicating that the water is below acceptable purity. Allow water to flow to drain for a short period to rectify this condition.
5.4
The battery condition should be checked each time the water purity is determined by raising the test switch and checking that the upper meter registers in the GREEN zone. The battery requires replacement when the meter registers in the yellow zone.
5.5
When the water inlet valve is closed (by turning clockwise) water will continue to flow from the deionised water outlet for a short time.

CARTRIDGE REPLACEMENT
6.1
Close the feed water valve.
6.2
Remove inlet hose connector from top of purification cartridge.
6.3
Remove purification cartridge from Micromeg unit.
6.4
Remove transit caps from replacement purification cartridge and fit to unit.

ROUTINE MAINTENANCE
7.1
BATTERY - To replace battery, remove exhausted battery from battery compartment by pulling the removal strap downwards. Remove red snap connector. Fit replacement.
7.2
FILTER WASHER - Inside the cartridge connector is a filter washer. Clean by washing in clean tap water at monthly intervals.
7.3
PURITY SENSOR - The water purity sensor requires cleaning every three months. Remove the deionised water assembly and the purification cartridge. Remove the filter washer and identify the metal plates mounted in the cartridge connector. Clean between the plates with a pipe cleaner and water.
