2). Water Supply System
Provide a water supply system that fulfills the requirements of the limits listed in Table 2-1. The
supply must provide a minimum dynamic pressure of 35 psi (2.4 kg/cm
pressure of 60 psi (4.1 kg/cm
·
If analysis shows that the supply water is NOT within the required limits, either a water
treatment system and/or carbon filter must be installed in the line feeding the steam
generator or the frequency of maintenance, cleaning, and descaling must be increased
beyond that recommended in the maintenance schedule (Chapter 3). If more frequent
descaling is selected as the means of protecting the steamer from premature failure, the
"DESCALE REQUIRED" light timing should be readjusted to reflect the increased cleaning
schedule.
b. Setting the Descale Required Light
The Descale Required Light feature
tracks the number of hours the unit has
been operating since it was last reset,
and lights when it is time for descaling.
1). General
The Descale Required Light consists of
an indicator light, a solid state timer
module, and a reset/rocker switch. (The
light and reset switch consist of a single
device on the front panel identified by the
"DESCALE REQUIRED" label.)
Figure 2-8. The timer is a digital clock
module inside the unit that keeps track of
how many hours your steamer has been
in operation since the last reset of the
timer.
