Adjust air flow (For OPTIMA XD)
Amount of air intake consumed can be subject to differ depending on ambient environment.
(※ Combustion gas should be visually transparent)
1. Open the plastic cover on the right side.
2. Slightly untighten air adjustment damper using a screw driver(+) and adjust an amount of
air intake manually.
3. Retighten the screw of Air Adjustment Damper
Black Smoke from exhaust flue :
Move air adjustment damper clockwise
Whitish Smoke from exhaust flue :
Move air adjustment damper counter-
clockwise
DO NOT breathe in combustion gas from the exhaust flue.
Moisture Control
Users can spray moisturized steam (wet steam) by opening the moisture control valve.
In the event of cleaning interior surfaces or water sensitive areas, ensure that the moisture
control valve is fully closed to minimize surface moisture.
Using two steam guns with the moisture control valve open continuously may
consume steam faster than what can be replenished. Open the moisture control valve
by 1/3 allowing pressure to build up.

16
Emergency stop
1. In case of a failure in the product or an emergent situation occurred, push the emergency
stop button in.
2. Overhaul the failure, take necessary measures and resume the emergency stop button.
How to use emergency stop button
Emergency Stop Resume Operation
Push emergency stop button
Release emergency stop button by twisting
clockwise
Emergency stop button will shut off all electrical power sequences inside the
main power enclosure.
Pause operation
1. Switch off the STEAM.
2. Close the steam outlet valves and release all the remaining steam from the hoses by
pulling the gun trigger. It prevents remaining of condensed water residue in the steam
hoses afterwards and increases the life span of the steam hoses and guns.
Shutdown operation
1. Switch off the STEAM.
2. After blower fan stops automatically (applied to XD model), switch off the POWER.
3. Release steam from the steam vessel by pulling the gun trigger until the pressure drops
down to 1~2 kg/㎠(28.4 psi).
4. Close the steam outlet valves and release all the remaining steam from the hoses by
pulling the gun trigger.
5. Release remaining steam from the steam vessel by opening the drain valve.
Keep drain valve open for the next operation
DANGER. Burn hazard! Hot steam. Keep hands clear.
6. In cold weather, take precautionary measures to keep water pipes from freezing and
bursting. (See page 21, "Freeze Prevention").
