INTRODUCTION
The basic
Reflect-O-Ray
®
EDS 6
system has a built-in
pre-purge of approximately 10 air changes. The system
also has up to two air changes of post purge as the
vacuum exhauster "coasts" to a stop.
Where a longer pre purge and post purge is specified, a
pre-wired series 5500 control panel is available.
The series 5500 control systems includes these basic
functions:
1. Additional protection for the system.
2. Approximately 40
seconds of pre purge.
3. Approximately 40 seconds of post purge.
The pre purge and post purge cycles will provide in excess
of 12 additional air changes within the radiant tubing
network.
The line voltage thermostat will prevent the system from
"short cycling" and allow the system to run long enough to
dry out the startup condensation within the radiant tubing.
The system must not be allowed to short cycle as required
and outlined in the warranty statement. It is recommend-
ed that a line voltage thermostat be used when a 24V-
thermostat control is required.
Please note that the timings listed may vary slightly from
system to system.

burners require the use
of one 24 VAC, 40VA transformer per burner assembly. It
is recommended that the transformer(s) supplied with
each burner be mounted as a cluster on the 5500 control
panel or remotely when voltage drop on long runs may be
a problem.
