Manual pump operation
If the LED display on the gas console shows coolant flow error 093, the pump must be turned on manually within 12
seconds of turning on the power supply, or the power will have to be turned off and then on again.
1. Turn ON the power. Press and hold the current selection knob (8) to turn on the pump manually, and allow the
coolant to flow for 60 seconds.
2. Write down the coolant flow rate shown on the gas console's LED display. The recorded flow rate will be used for
comparison during some of the tests. Coolant flow must be greater than 2.3 lpm (0.6 gpm) for the system to operate.
3. Release the current selection knob (8) and then turn OFF the power.
Note: a flow diagram can be found on schematic 013348, sheet 14 of 17
