WATERMAID Cell Connection / Disconnection

The Watermaid QT Series cells and the EZ300 Cell attaches to the Watermaid Power Supply via a 30 Amp rated power cord and a 30 Amp rated Electrical Junction Box, located underneath the Watermaid Unit.

When accessing the Electrical Junction Box, underneath the Watermaid Unit, please ensure ALL power to the unit is turned off and disconnected

To Disconnect the Cell:

You will need a Phillips Head and Flat Head Screwdriver.

With the Philips Head Screwdriver, undo the screw and remove the black, plastic junction box cover. Underneath the cover will be exposed, 3 Brass Electrical Connectors.

With a Philips Head Screwdriver, Loosen the Cord Grip Screw (silver in colour) and then proceed with a Flat Head* Screwdriver to undo the Brass Terminal Screws to enable the cord to be pulled free from the Electrical Connections.

* Although the brass connectors will take a Phillips Head Screwdriver, they may burr the brass connectors. A Flat Head Screwdriver will do a more efficient job without damage to the terminal.

Connecting the Cell:

Simply repeat the steps in the reverse order above to reconnect the cell back to Power Supply. Please ensure that the Wires are Connected back the correct way.

PLEASE BE CAREFUL & ENSURE that the terminals crimps on the ends of the cell wires are located underneath the brass screw. NOT the plastic cables. The brass screw connector may cut the cable if not located correctly. Please refer to pictures below.

A NEW Cell Wire Colours:

A NEW WATERMAID cell has the wire colours;

RED, BLACK and  WHITE   see picture above.

With a NEW WATERMAID cell, The BLACK wire connects to the BLUE or BLACK wire that feeds back inside the Watermaid Power Supply. This is the Negative Terminal.

The RED wire connects to the RED or BROWN wire that feeds back into the Watermaid Power Supply. This is the Positive Terminal.

The  WHITE   wire connects to the  WHITE  or BLACK wire that feeds back into the Watermaid Power Supply. This is the gas detection wire (This is NOT an Earth wire). This wire is always a smaller diameter wire.

All three wire must be connected inside the junction box for the unit to operate efficiently.

 

Fitting a NEW WATERMAID Cell to an Older Power pack.

When a NEW WATERMAID Cell is fitted to an older Power Pack, the NEW cell wires will be:

RED, BLACK and  WHITE  .

These should be connected to the Older Power Pack where the wires coming out of the Power Pack may be either:

BROWN, BLUE and  WHITE  (where the white wire is the smallest) or
BROWN, BLUE and BLACK(where the black wire is the smallest)

See Picture below for clarification.

 

Fitting a OLD WATERMAID Cell to a NEW WATERMAID Power pack.

When an OLD WATERMAID Cell is fitted to a NEW WATERMAID Power Pack, the Old cell wires may be:

BROWN, BLUE and  WHITE  (where the white wire is the smallest) or
BROWN, BLUE and BLACK(where the black wire is the smallest)

These should be connected to the Older Power Pack where the wires coming out of the Power Pack are either:

BROWN or RED,
BLUE or BLACK and
 WHITE  or BLACK (where the white or black wire is the smallest in diameter)

See Picture below for clarification.

 

Maintenance:

It is recommended to check the junction box terminals every 4 - 6 months to ensure they are tight and also to spray WD-40 or similar onto the terminals to keep moisture away.

Loose or corroded terminals will result in burnt wiring which may result in a loss of chlorine production.
