Miura Steam Boiler LX-200

No work other than that clearly indicated below is to be carried out on the boiler. Failure to observe this precaution may result in injury.

Do not start blowdown until you have first confirmed that the boiler has been shutdown. Failure to observe this precaution can result in burns and other injuries.

There is no need to carry out blowdown immediately after the display presents a blowdown request during normal boiler operation. It is recommended to wait until the next startup on the following operating day.

The system will inform you that regular blowdown is required by lighting the Status lamp in yellow and outputting the message “BOILER CHECK1” on the display. (The display’s “B” indicator will also flash at this time.)

Although the Status lamp will turn off and the display’s blowdown request will be cleared when the “DATA” button is pressed, the “B” indicator will not.

Blowdown must always be carried out in strict accordance with instructions given by MIURA maintenance personnel.

Warning: No work other than that clearly indicated below is to be carried out on the boiler. Failure to observe this precaution may result in injury.

Confirm that the chemical feed is as required.

Confirm that sufficient liquid is present to properly dissolve chemicals.

Confirm that there is no air in the chemical feed pump or feed line.

Warning: Protective glasses and rubber gloves must be worn when adding chemical compounds. These compounds may cause sight loss, burns, and other injuries when they contact with skin or eyes.

If boiler chemical comes into direct contact with skin, immediately wash away using cold water.

If this chemical enters an eye, immediately wash away with cold water and seek medical attention.

Always follow the instructions of your water treatment personnel in terms of chemical dosage.

No work other than that clearly indicated below is to be carried out on the boiler. Failure to observe this precaution may result in injury.

To keep your MIURA boilers running in optimum condition, be sure to check the following daily:

ii. No air in the chemical feed pump or lines.

i. Boiler Make-up water is completely soft (use a test kit sensitive to less than 1.0 PPM).

ii. Make sure the water softener timer or softener flow meter is working every day.

Warning: No work other than that clearly indicated below is to be carried out on the boiler. Failure to observe this precaution may result in injury.

Startup the boiler as described in Section 8.1: Boiler Startup.

Confirm that the reading on the steam pressure gauge is in the normal range, and that the gauge pointer is not swinging wildly.

Warning: If the steam pressure is not within the normal range, immediately shutdown the boiler and contact a MIURA sales office or your local dealer for further instruction. Continued use of the boiler with abnormal steam pressure levels may result in boiler damage, which in turn could lead to injury.

Warning: No work other than that clearly indicated below is to be carried out on the boiler. Failure to observe this precaution may result in injury.

Warning: Water in supply lines for boilers connecting to a deaerator or hot water tank is extremely hot. For this reason, you should wait until the tank water has sufficiently cooled down (at least two hours after boiler shutdown) before performing this work. Failure to observe this precaution can result in burns and other injuries.

Turn off the breaker for the boiler’s main power. Confirm that the steam pressure gauge is reading 0 PSI. If this is not the case, stand by until the pressure reading drops to zero.

Warning: Never operate the breaker for the boiler’s main power supply with wet hands. Failure to observe this precaution may lead to electric shock and have other undesirable consequences.

Open the blowdown valve for the feed water tank.

When the discharge of water ends, close the feed water tank’s blowdown valve.
