HUMIDIFIER
WATER SUPPLY
RATE2
(26)
The humidifying tray did
not fill within the specified
amount time during
humidity testing. The
chamber has been
stopped. If the backup
mode is ON, humidity
tests are suspended, but
temperature tests
continue. The strainer on
the humidifying
water supply
circuit is either
clogged or the
circuit is leaking,
or water supply
pressure is too
low. Check the humidifying water
supply circuit (wait for the test
end if the backup mode is on)
and correct as necessary.
Then, resume testing. If the
same alarm occurs again, call
for service.
DRY WICK
(26)
During humidity testing,
the wet-bulb (measure
relative humidity) rose
above the specified
temperature. The
humidifier will continue as
is, but humidity control
might destabilize and
trigger a humidity alarm. The wet-bulb
wick (woven
cloth) inside the
chamber may be
dry. Stop the chamber and replace
the wick. After wet-bulb
temperature returns within the
specified range, the alarm can
be cleared by pressing the
Buzzer Stop key.
