Troubleshooting

The hose heat transformer voltage must be set to match the hose length in use. Too much power will cause the hose heat circuit fuse to fail. Too little power will result in insufficient hose heating.

c.Adjust the tap setting of the hose heat transformer to match the next shortest length of heated hose (see Hose Heat Power Pack on page 24).

d.Unplug the next set of Power-Lock connectors and plug the hose jumper plug into the last “upstream” segment of hose.

e.Restore electrical power, switch ON the hose heat circuit and adjust the hose heater power control to 15 amps.

If hose heat is restored, then the fault is within the last unplugged segment of hose.

If hose heat is not restored, turn the hose heater power control fully counterclockwise, then turn OFF the hose heat circuit breaker and the main power disconnect and repeat Steps c through e until the fault is located.

5.Primary Heat and Hose Heat Temperature Setting - The purpose of the hose heater is not to add heat but rather to maintain the temperature developed by the primary heater. If indications are that the hose heater is not maintaining temperature during flow, check that the primary heater and hose are set for the same temperature or reduce the output.

6.Low Line Voltage - The hose heat system operates at 220 Volts. Low line voltage will significantly reduce power available and the heater will not perform to its full capability at maximum hose length. A qualified electrician should determine the secondary amperage of the hose heat circuit and adjust the tap setting as required to achieve a secondary amperage of 45-50 amps.

7.Hose Heat Transformer Tap Setting - The transformer voltage is adjustable to accommodate between 35 ft and 310 ft of hose. Ensure that the proper tap setting is selected for the hose length in use. (See Hose Heat Power Pack on page 24).
