Typical installation

This document does not contain sufficient information to install the

system safely. See the Installation and Maintenance Instructions

supplied with the products for full details.

automatically controlled steam boilers and provide the control and

alarm functions specified by British Standards in BS 2790, by the

Health and Safety Executive in PM5 and by SAFed (PSG2).

OK

The LCS1000 systems require daily manual testing as specified

in PM5 and a trained boiler attendant should be on site at all times

the boiler is in operation.

The level controls and level alarms are probably the most important

controls on the boiler for ensuring safety and should only be installed

and maintained by suitably trained personnel. Spirax Sarco can

install, commission and provide a regular maintenance service.
