Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions

(IM-P148-37) supplied with this product.

Installation note:

The trap should be fitted in the horizontal plane below what it is

draining, with the direction of flow as indicated on the body so that

the float mechanism is free to rise and fall in a vertical plane.

One of the advantages of the float trap for draining air and gas

systems is that no bleed is required for satisfactory operation.

However, because the trap has no bleed a separate balance line

is needed to prevent it becoming air or gas locked.

Make sure that the balance line is piped back to the upstream side.

A balance line is essential for the correct operation of this

product.

For convenience of maintenance it is recommended that a union

is fitted in the balance line near to the trap cover.

Disposal:

The product is recyclable. No ecological hazard is anticipated with

the disposal of this product providing due care is taken.
