Water Purge
NOTICE
Proper Water Treatment Required!
The use of untreated or improperly treated water
could result in scaling, erosion, corrosion, algae or
slime.
Use the services of a qualified water treatment
specialist to determine what water treatment, if any, is
required. Trane assumes no responsibility for
equipment failures which result from untreated or
improperly treated water, or saline or brackish water.
During the unoccupied mode, water-cooled units will
periodically circulate water through the condensers and
waterside economizer if the user has enabled the purge
function at the HI. The water purge function circulates
water to introduce fresh water-treatment chemicals and
help prevent water stagnation. The number of hours
between each periodic purge, or purge duration, is user-
defined at the HI between 1-999 hours. If the periodic
purge timer expires while the unit is in occupied mode, it
will wait for the next available unoccupied time before
initiating water purge.
Contrary, if a request for cooling occurs during a purge
sequence, purge will terminate and cooling will commence.
