Page 10: Pre-Start Procedures
Pre-start Procedures Steps: 1. Connect the steam hose and gun to the steam outlet valve. Ensure a tight connection (use tools). 2. Fill the water tank with soft water. When tap water is used, add anti-scaling solution to the water tank as instructed by the supplier.
Page 11 Water Quality Matters! Water quality can greatly affect the Optima’s life span/time and performance. It is important to use SOFT WATER. If tap water is used, daily use of water treatment (water softening liquid) and regular sediment removal will help ensure efficient operations (see page 14 “Maintenance A & B” for more information).
Page 12: Initial Operation
Initial Operation “Initial operation” means operating the machine after draining all water from the steam vessel. After completing the pre-start procedure, follow the steps below. Steps Instructions / Corrective action Type Signal indications Make sure the water tank is full. (If using the auto water filling system, connect water hose to water supply source, i.e.
Page 13: Standard Operating Procedures
Standard Operating Procedures Steps: 1. Turn on the POWER (EMERGENCY STOP) switch, and then turn on the STEAM switch. If the alarm beeps once, and the POWER light is on, the machine is ready to operate. (If you are starting the Optima for the first time or using after draining the steam vessel, refer to “Initial Operation”...
Page 14: Moisture Control
Moisture Control You can increase the moisture content in the steam by opening the moisture control valve. Increasing the moisture content in the steam increases water consumption and may produce water run-off. Dry steam may persist due to extremely hot weather; adjust the moisture control valve accordingly. When cleaning and/or sterilizing interior surfaces, ensure that the moisture control valve is closed to minimize surface moisture.
Page 15: Pause Operations
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.
Page 16: Freeze Prevention
Freeze Prevention The Optima Steamer can perform in the sub-zero weather. However, it takes precautions for storage. In cold climates it is necessary to store the Optima in an area where the temperature is above freezing. Unplug the machine from electrical source and follow steps below to protect the Optima against ruptured lines and damage caused during cold climates.
Page 17 3. Drain the water suction lines and the water pump. Open the drain valve or Y-strainer drain cap, then disassemble / detach water suction line from top of water pump and drain all remaining water using compressed air. Keep drain valve open until next use.
Page 18: Maintenance
Maintenance Warning! Unplug the machine from electrical source and allow it to cool off before conducting maintenance. Wear appropriate safety protection. Note: To avoid unexpected downtime, keep up with maintenance schedule. Maintenance Schedule Every year Monthly or Maintenance Items Daily or as as needed needed...
Page 19 B. Check for/drain sediments from steam vessel Open the drain valve and check the color of the water. If the water is milky, drain all remaining water & sediment from the steam vessel by opening the Y-strainer drain valve or cap. C.
Page 20 E. Check/clean water probe sensors. The Optima has three water probe sensors (High, Com, Low). Scale build-up on the water probe sensors can affect sensor accuracy and will prevent the machine from operating abnormally. What you will need: screw driver (+), 14mm deep socket wrench, breaker bar (DO NOT USE A POWERED/TORQUED WRENCH!!!), sandpaper, and Teflon tape.
Page 21 F. Perform vessel de-scaling. What you will need: screw driver (+), wrenches, 10mm T-box wrench, container (14liters or larger), 14 liters (3.7 gal) of diluted de-scaling liquid, and 2 liters (0.5 gal) of clean tap water. Steps: 1. Remove the top and lateral covers. 2.
Page 22 Note! Check local regulations regarding the disposal of de-scaling liquid. Depending on the de-scaling product used, a special disposal method may be required.
