Models MS-250/255 CAUTION Water pressure must not exceed 30 psi (2.1 kg/ cm 2 or 207 kPa). Higher water pressures may cause poor performance or flooding. To reduce water pressure, install a water pressure regulator, and set water pressure to 20-25 psi (1.4 - 1.7 kg/ cm 2 or 138 - 172 kPa).
General (All Units Except MS-150/250 - Mfg. #9100424, 432, 433 & 439) When the Operate button (Figure 5a) is pressed, power is supplied to the water pump (MS-150/155/355) or the solenoid valve (MS-250/255). The pump/solenoid operates and water sprays onto the heated Steam Generator.
• Shot Interval Time (SHO) = 00 min., 20 secs. (Range: 3 seconds to 5 minutes 59 seconds) • Steam Shot Time (H O) = MS-150/155/355 - (1_00) MS-250/255 - (0_70) (Range: 0_10 second to 2_50) This converts approximately 3/4 oz. (25 milliliters) of water to steam every 20 seconds for a 15 minute cooking cycle.
