Installation:

The trap should be installed with the float arm in horizontal plane. Must be fitted below the drain point of the equipment.

Isolating valve should be installed upstream and downstream of the trap for safe maintenance.

Always open isolation valve slowly until normal operating conditions are achieved to avoid system shocks.

It is recommended that an equalizer line be fitted.

Maintenance:

The trap can be maintained without disturbing the piping connections. Ensure that trap is isolated upstream and downstream before attempting to dismantle it. Allow the trap to cool before dismantling.

Item 3 (gasket), 4-5-6 (valve assembly), 7 (ball float) can be replaced bring the traps as new conditions.
