Safety information, installation and

maintenance

For full details see the Installation and Maintenance Instructions

(IM-P187-05) supplied with the product.

Installation note:

The TDC46M is designed for installation with the disc in a

horizontal plane with the insulating 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.

How to order

Example: 1 off Spirax Sarco DN15 TDC46M thermodynamic

steam trap having flanged EN 1092 PN40 connections.
