INSTALLATION OF THE EXTERNAL CONTROL CABINET (S)
1.
Scope of supply and accessories
1.1
Scope of supply
The external switch cabinet for EPP consists of the lower part and the cover hood with:
• Lock security pin with installation material
• 2 locking screws, M8, for fitting the one2clean control unit (wing nut and washer enclosed with the one2clean
control unit).
• Cable screw connection M20x1.5 for power supply
1.2
Accessories required
The installation of the switch cabinet requires the following items:
• Empty pipe closure element, rated diameter 100 for the gas-tight closure of the technical connection pipe
• KG pipes, rated diameter 110, as technical connection pipe to the clarification system
• Earth contact coupling for the electrical connection of the control unit
2.
Choosing the location
When choosing the location for the cabinet, the following points must be borne in mind:
• During the summer months the location should be protected from direct sunshine.
• The rear face of the cabinet must be placed with at least 10 cm of clear space from the nearest wall.
• Operation can be noisy! The air compressor produces a sustained noise of long duration when in operation
(comparable to an oil heating fan or a freezer cabinet).
• The air hoses should not be longer than 20 metres.
• The switch cabinet must not be allowed to stand in ground water. This also applies to ground water or backed-up water
which only occasionally occurs.
• Power supply is to be via a separately fused power connection (16 Ampere, time-lag). Any additional consuming
components on the same fuse can interfere with operations.
The connection of the empty technical supply pipe is effected to the side of the cabinet with the aid of a cable connection
socket with rated diameter of 110.
