Pause Operations
(Follow these steps if you intend to stop using steam for more than 5 minutes temporarily.)
Steps:
1. Turn the STEAM switch off.
2. Close the steam outlet valves and pull the steam gun trigger to release any remaining steam in
the hoses. This will prevent the release of water (condensed steam) and increase the life span
of the steam hoses and guns.
Note!
When manually refilling the water tank, must turn off the STEAM switch.
After refilling the water tank, turn the STEAM switch back on then resume operation.
Shutdown Procedures
Steps:
1. Turn off the STEAM switch.
2. Turn off the POWER (EMERGENCY STOP) switch
3. Use up existing steam in the steam vessel until the pressure drops to 1~2 bar (15~29 psi). Then
train out all water from steam vessel by opening the drain valve. If the water from the steam
vessel is milky, open the Y-strainer drain valve (cap) and clean the filter of Y-strainer
4. Close the steam outlet valve and pull the spray gun trigger to release the remaining steam in the
hoses. This will prevent the release of water (condensed steam) at next use and increase the
life span of the steam hoses and spray guns.
5. In cold climates or cold weather condition, additional steps are required to prevent damages.
(See "Freeze Prevention" on page 12).
Tips!
