9 Troubleshooting
WARNING: Troubleshooting procedures
involve working with high voltages and/or
temperatures which may result in personal injury
or death, and should only be performed by
trained personnel. Please do not hesitate to
contact Koehler for assistance.
9.1 Unit does not power up
Establish that the socket outlet is providing
proper and adequate voltage.
Check if Overpower Protection circuitry
located directly behind the temperature
controller inside the front tray has been
activated.
Check if line switch is in the ON position.
If problem persists, please call the Koehler
technical service department for assistance.
9.2 Unit is on and keeps resetting into
start up routine
For 220V units, make sure that the socket
outlet is greater than 215V.
Check if there is a steady and reliable power
source.
Make sure the connector plug on the rear
panel is firmly plugged in.
9.3 Unit is on but bath does not heat up
Make sure that the actual temperature
reading is not higher than the set-point
temperature.
Determine if the temperature controller is
properly calibrated by comparison to an
ASTM standard thermometer.
Determine if the Overtemperature Protection
(OTP) circuitry as been activated.
9.4 Bath heats up but temperature does
not stabilize
Make sure there are no drafts from open
doors, windows, or environmental control
vents in the vicinity of the bath.
If the set temperature is close to ambient,
then you may need to circulate cold water
through the coils in order to achieve proper
temperature stability.
