Anti-scaling water treatment
If water other than treated soft water is used, scale will build up on steam vessel walls, probe
sensors and pipes. This will adversely affect the performance and lifespan of the machine. In order to
prevent this, we recommend operators to use anti-scaling solution. Simply add anti-scaling solution
every day and ensure that the steam vessel is drained at the end of the day. This procedure will
prevent scale build-up inside steam vessel and increase the thermal efficiency of the machine.
Use manufacturer recommended steam vessel anti-scaling solution only.
3. Connect the machine to required power source.
Make sure that machine switches and breaker switches are off before connecting the machine to a
breaker. Connect the power cable, R, S, and T for 3 phase models EST(12K, 18K, 27K) and P and N
for the single phase model [EST (05K)] to the breaker. Connect the grounding cable to grounding
point and turn on the breaker switch.
Water Quality Matters!
Water quality can greatly affect the Optima’s life span/time and performance. It is important to
use
SOFT WATER
. If tap water is used, daily use of water treatment (water softening liquid) and
regular sediment removal will help ensure efficient operations (see page 14 “Maintenance A & B”
for more information).
Do not use distilled water. Do not put any other chemicals or detergents into the water
tank or steam vessel.
The feed water temperature should be above 5
℃
(40
℉
).
