Miura Steam Boiler LX-200

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.

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.

Using the boiler’s gas pressure gauge, confirm whether the gas is pressurized to the required range (i.e., 3 to 5 PSI)

If the reading on the gas pressure gauge is not within the required range, immediately shutdown the boiler

If the reading on the gas pressure gauge is not within the required range, contact a MIURA sales office or your local dealer for further instruction.

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.

If the water volume, for any reason, falls below the pre-determined water volume, combustion will immediately be stopped and if it is not recovered after 15 sec after combustion shutoff, a warning alarm will be activated. The display will read, “WATER ALARM 1”.

Open the ball valve at the bottom of the LVC and allow time for the steam pressure to force the water out of the LVC.

When the low water cut-off probe loses contact with the water for more than 15 seconds, the boiler will shift to stand-by mode first and shut down 15 seconds, the alarm will sound and the BL11 Microcomputer will display “WATER ALARM 1”.

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.
