This article outlines the required electrical components and connections in order for Max-E Boost to operate properly.

General

Ensure that the electricity supply has been suitably isolated and cannot be switched on, before removing the terminal box covers of the pump motor, and before any removal or dismantling of either item.

All electrical connections should be carried out by a qualified and authorised electrician in accordance with local site regulations and also in accordance with the latest issue of the I.E.E. regulations.

The metal work of the Max-E Boost must be earthed. It is strongly recommended that an Earth Leakage Circuit Breaker (ELCB) is fitted to the incoming electrical supply.

Ensure that the electrical supply and the cabling to the Max-E Boost isolator switch is able to meet the current load of the booster set.

The Max-E Boost is suitable for a single phase supply voltage of 230V +/- 6%, with a 10 amp maximum MCB or fuse. The Max-E Boost full load current is 6.8 amps on a 240V 1ph 50Hz supply.

Electrical Connections

Do not attempt to start the pump even to check the direction of rotation until the system has been filled with water and both the pump and the system have been vented.

Please ensure that the booster set is suitable for the electricity supply on which it will be used. All cables must be of an adequate size to prevent an excessive voltage drop in the supply to the booster set, the required cable size is 1.5mm² . The electrical installation should be in accordance with the latest issue of the I.E.E. regulations.

Electrical Supply Connection

The mains electricity supply is connected into the isolator switch mounted on the base plate. Follow the sequence below to open the isolator switch housing in order to connect the electrical supply wires into the isolator switch. The Max-E Boost must be permanently wired into a fused switched outlet, or a consumer box with a 10 amp MCB.

Anchor Tool

The anchor tool is used to open the jaws of the connector blocks, and is stored in the motor terminal box.

If the tool is damaged or breaks, a very small flat bladed screw driver can be carefully used to operate the jaw mechanism.

Float Switch

To connect the float switch, remove the factory fitted white wire link between terminals 2 and 3, using the anchor tool provided.

Then connect the float switch wires into the same terminals. The motor requires a closed contact on terminals 2 and 3 for a healthy condition to run.
