RECOMMENDATION

: If the dehydrator 

overhaul process has taken more than a few 

hours, it is recommended that the unit be run for 

one hour into the room, to purge the membrane 

dryer and tank of any acquired moisture, before 

reconnecting to the transmission line system.

Reverse the steps followed initially to remount 

the dehydrator.  To reconnect the dry air lines; to 

reconnect the power and alarm cabling; to turn 

the unit back on; and finally, to open the valves 

to the waveguide system so that the dehydrator 

is again providing dry air under pressure to the 

transmission line system.
