Even though there is a monitor scale in the front of Pressure Switch, setting a value from there is very

Sequential Drain Timers (
For Auto Drain Models)
These are the drain timers on which the draining times and duration adjustments are made
for automatic drain function. On this timers you will find two dials to make the time
adjustments. Upwards dial controls the duration of the automatic drain which the drain
valve remains open (drains the condensate) It is adjustable between 0 to 10 seconds. The
dial does not have figures showing the times on it; it needs to be proportionally adjusted.
The full scale shows 10 seconds while half of the scale indicates 5 seconds. The downwards
dial is used to adjust the time period of the automatic drain during which the drain valve
will remain closed. Draining time periods and duration are adjusted as 5 seconds for every
10 minutes. Factory settings should not be changed for trouble free operation.
Caution!
• Do not adjust the safety valves and do not alter their original settings. Only authorized
service technicians are certified to make such adjustments. If required, replace and
return the old one for reconditioning to the manufacturer or to a dealer nearest you.
• Do not remove the leaking safety valves and do not replace it with a plug. This may be
extremely dangerous. If safety valve leaking, replace it.
