Safety information, installation and maintenance
For full details see the Installation and Maintenance Instructions
(IM-P068-24) supplied with the product.
Installation note:
The TD42 is designed for installation with the capsule 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.
