Minivap Trouble-shooting Check-List
-Use manual drain switch to check pump operation (On/Off switch in 'off position)
Check/cause/remedy
-Check main power is connected and switched on.
-Check security circuit is complete (fan interlock, high humidity override).
-Check power supply fuses.
-Check Power-On neon.
-Check the switch is in the position marked 1 (unit On position).
-Check Minivap internal control circuit fuse.
-Check humidistat.
-Minivap automatic STOP function has operated for one of the following reasons:
a) Feed Fault STOP
b) Drain Fault STOP
c) High Overcurrent STOP
If no obvious Feed Fault condition (a) exists, i.e. no water in cylinder, assume that (b)
or (c) applied. Carry out full inspection of cylinder and drain pump. Switching the unit
Off and On again cancels the automatic STOP condition but user should not put unit
back into service until the above action has been taken and the cause of the
interruption remedied.
-Slow start-up situation with a new cylinder. Low conductivity (soft) water. Add Alka
Seltzer to boost conductivity of the water. If above action is not successful and
condition returns, an alternative lower resistance cylinder may be necessary
-Reduced output due to scale deposits,.
Remove cylinder for rinsing out and re-use or fit a new replacement cylinder.
