Calibration of the reference machines
Wascator FOM 71 CLS
Checks to be made
1. Heating element power ***WARNING***
Remove the front panel and measure the cold resistance of the heating
elements. The elements shall be at ambient temperature and the machine
should not have been run for at least 5 hours.
Resistance at 20° shall be:
Rated voltage according to
Resistance
data label attached on machine
400/230 volts
28.5 - 29.7 ohms
415/240 volts
30.9 - 32.2 ohms
2. Visual heating element inspection ***WARNING***
Remove one of the heating elements and visually inspect for and build up of
lint, limestone, etc. which can cause reduced heater efficiency.
3. Line voltage ***WARNING***
Measure the rated voltage between L1 - L2 - L3 on the incoming mains to the
machine.
4. Leveling of the machine
The machine must be installed on a flat horizontal surface. Check that the
top of the machine is horizontal. Measure with a water-level. Deviation from
horizontal at any top panel corner must not exceed 5 mm.
5. Drain installation
Check drain installation, minimum drain diameter 50 mm. A drain with a 150
mm free vertical flow is recommended but not compulsory.
6. Water supply
Check of water supply pressure and supply filling rate. Supply pressure
shall be between 200 - 600 kPa (2-6 bar). Measure the supply time using the
”weight check” program:
FOM 71 CLS
Program 993 (18 kgs)
The machines shall be without load.
Supply time to 18 kgs shall be 60 - 75 seconds.
