For full details see the Installation and Maintenance Instructions

(IM-F01-30) supplied with the product.

Installation note:

The ISMC32 is designed for installation with the bimetal element in

a horizontal plane with the cover at the top.

It is recommended that a non-return valve is fitted when discharging

condensate into return lines where backpressure is experienced. It

is also recommended that a diffuser is fitted when discharging to

atmosphere.

For ease and maintenance, consideration should be given to fitting

isolation valves upstream and downstream of the steam trap.
