Shutdown - Mi-T-M HDB Serie Manuel De L'utilisateur

OPERATING INSTRUCTIONS
ADJUSTABLE THERMOSTAT:
Regulates the maximum discharge temperature. Turn the dial to the
desired maximum discharge temperature. This may cause the burner to fire
intermittently.

SHUTDOWN:

1. Move the Burner switch to the OFF position.
2. Squeeze the trigger and discharge the water for a period of three minutes
to cool the heat exchanger and high pressure hose. Insufficient cool-down
periods for the high pressure hose will cause excessive wear and eventual
rupture of the hose.
3. Do not close the choke to stop the engine. Backfire or engine damage may
occur.
4. Move the engine key switch to the OFF position.
5. Turn off the water supply and trigger the gun momentarily to relieve trapped
pressure.
Disconnect and drain the high pressure hose, gun, and lance. Wipe the unit
clean. Store in a non-freezing environment.
