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. The blower fan will be shut off automatically after 30 seconds to remove excess fumes.
3. 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 or fuel tank, turn off the STEAM switch first.
After refilling the water or fuel tank, turn the STEAM switch back on and resume operation.
Shutdown Procedures
Steps:
1. Turn the STEAM switch off.
2. After 30 seconds, the blower fan will automatically stop. Once the blower fan stops running, turn
off the POWER (EMERGENCY STOP) switch.
3. Use up the existing steam in the steam vessel until the pressure drops to 1~2 bar (15~29 psi).
Then drain 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 13).
Extend the life span of the Optima
1. Use soft water or clean tap water.
2. Use water treatment daily if tap water is used.
3. Always remove steam from hoses, spray guns, and the steam vessel after use.
4. Store the Optima at room temperature.
5. Remove sediments from the steam vessel regularly. (See “Maintenance” on page 15).
6. Remove hardened scale from the vessel regularly. (See “Maintenance” on page 15).
7. Use only clean diesel. Never use a recycled- diesel or other types of fuel.
