2) The heating element must be functioning properly.
The lack of either of these conditions may cause erratic temperature control and
possible overheating. The thermocouple is properly positioned and mechanically
locked in place at the factory. However, during maintenance or changing of the
thermocouple, the positioning may have changed. Refer to the Maintenance section
of the manual for proper thermocouple positioning. Check the resistance of the
heating element; it should be 32 ohms.
7. The primary heater rating is 6000 Watts at a voltage of 220 Volts. Low line voltage
will significantly reduce the power available and the primary heater will not perform
to its full capability.
8. The efficient Primary Heater design of the H-20/35 VR maximizes the heat transfer
from the power available. However, under certain conditions the heater will not be
able to reach the required temperature and will require a reduction in flow or the use
of an auxiliary hose heat system. Call Gusmer Sales for information.
