HOSE HEATING
WARNING! Before correcting any kind of defect, make sure
the Main Power Switch is OFF and incoming power is locked
OFF. NEVER access the inside of the Control Panel with the
Proportioner power supply ON. The Heated Hoses are
components which reach high temperatures. Wait until they
have cooled before handling.
CAUTION! All electrical testing must be done by a qualified
electrician.
Follow the recommended procedure in the indicated order to solve the problem and avoid
unnecessary repairs. Make sure all Switches are in the correct position and Indicator Lights ON
before determining the existence of a fault.
PROBLEM:
A-Heated hose does not heat and the display on the controller shows ambient
temperature.
SOLUTIONS:
1. Check that the light on the on/off switch is lit when the heater is turned on, if not
replace the switch.
If the light is on, move on to the next step.
2. Check the Hose Heat Breaker in the main console reset the breaker. If it
continues to trip wrap an Amp Clamp around one of the wires coming off the
breaker. If it does not draw more than the rated value of the breaker, the breaker
needs to be replaced.
If the breaker is not tripped, move on to the next step.
3. Check the circuit breaker mounted on the transformer and reset the breaker if
necessary. If it continues to trip wrap an Amp Clamp around one of the wires
from the transformer going to the heated hose. If it does not draw more than the
rated value of the breaker, the breaker needs to be replaced.
If the AMP draw is less than the rated value, move on to the next step.
4. Check that the tap setting on the transformer is set for the proper hose length.
If it is set correctly, move to the next step.
