Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions

(IM-P148-37) supplied with the 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.

Advice on welding of socket weld variants is provided with the

installation and maintenance instructions.

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.
