This is the Instalation Instruction for the

Single Pump Double Timer unit.

Mounting the Box

Note that the box has mounting holes provided at the top of the base.
The two + marks at the top of this sheet are the drilling marks for mounting the box.
Using this template drill two holes for the rawlplugs.
Mount the unit using screws through the holes provided in the top left and right corners of the box.

Use rigid tubing which you can push into the pump tubing, fastening with a small cable tie.
If you use soft tubing, insert a non-corrosive ferrule into the tubing prior to insertion into the pump tubing to prevent the pump tubing and the cable tie from collapsing the tubing and restricting the flow.

Support the tubing near the pumps so that the weight of the tubing does not hang on the pump tubing, which would cause the pump tubing to collapse.

Make sure that the tubing used is compatible with the substance to be pumped, as certain types of tubing are damaged by strong acids and alkalis.

This unit has one double timer and one pump. Both times are adjustable.

Detailed explanation of the connections shown on the sticker inside the box:

Earth must be connected to the green wire on the connection block.
220 volt Power for the circuit must be connected to the blue and red wires on the connection block.
The blue wire is connected to neutral and the red wire to live, which must be from a point which is OFF when the machine is OFF, and it must be ON when the machine is ON.

The wash cycle must now be connected. There are 2 possibilities:

1. The machine may have a line which will go live when the wash starts.
WARNING: Make sure that the line does not go live at any other time. If it does then the dosing unit will be given the wrong information.
Simply wire it to the "Trigger" connection on the connection block.

2. The machine may simply have a switch or relay point with nothing connected.
In this case run a wire from the red "Trigger LIVE" connection on the connector block to one side of the switch or relay point. Wire the other side to the "Trigger" connection block.
