Hydrim L110W P3 & P4 Cycle with Revision 2.02 Software
1. Preparation drain pump runs
When the P3 or P4 cycle button is pressed the drain pump turns ON. The Hydrim will drain
the wash chamber and the sidebag. If the previous cycle was interrupted when the cycle is
started the drain pump will run for 80 seconds. If the previous cycle was a complete cycle
the drain pump will run for 20 seconds. If the unit fails to drain an
E4 code
will appear on
the display.
2. Sidebag fills with cold water target temperature 28
°
C/82.4
°
F
Turn ON Y1 cold water valve. Start timer whenever valve is open to calculate the Water
Debit Constant and Error Timer for filling sidebag. If water does not close pressure switch
B1 within 130 seconds Hydrim fails with an
E2 code
. When the pressure switch closes
calculate the Water Debit Constant time for filling up 2.7 liters.
3. Fill wash chamber target temperature 28
°
C/82.4
°
F
When sidebag is full and pressure switch B1 activates (blue arm moves out) turning ON Y6
sidebag drain valve to allow sidebag to drain into the chamber. Pressure switch will
deactivate when sidebag starts draining into chamber. After approximately 45 seconds turn
ON circulation pump M1 and Y1 cold-water valve. The on time for the cold water inlet
valve depends on the “Water Debit Constant” that was calculated previously. The chamber
capacity is 4 liters, 2.7 liters from the sidebag and 1.3 liters from the cold water inlet valve,
resulting valve Y6 is on for approximately 75 seconds and valve Y1 is on for 1.3/Water
Debit Constant. When water inlet valves timer expires add 10 seconds to the sidebag drain
valve Y6 before closing. Failure to fill chamber will cause an
E2 code
.
4. Circulation, heating and dosing target temperature 28
°
C/82.4
°
F
Start circulation pump M1, dosing pump M4 and turn ON water heater R1 if water
temperature in chamber is below target temperature. Start heating and dosing error timers.
Dosing pump runs for 2 seconds. If flow switch does not detect dosing before the dosing
error timer ends (30 seconds), the Hydrim fails with an
ED code
. Once selected dosing time
is achieved the dosing pump will turn OFF.
5. Circulation
Circulation pump M1 remains ON for 240 seconds/4 minutes. Turn ON Y7 hot water valve
and fill sidebag, target temperature 50
°
C/122
°
F.
6. Circulation and evacuation 10 seconds
Circulation pump M1 remains ON. Turn ON drain pump M2.
7. Evacuation 20 seconds
Circulation pump M1 turns OFF. Drain pump M2 remains ON for 20 seconds.
8. Wait until sidebag is full target temperature 50
°
C/122
°
F
Y7 the hot water valve remains ON. If water temperature is higher than the target
temperature then turn ON Y1 cold-water valve. Start timer whenever valve is open to
calculate the Water Debit Constant and Error Timer for filling sidebag. If water does not
close pressure switch B1 within 130 seconds declare “no hot water” and use just cold water.
If pressure switch does not close after another 130 seconds Hydrim fails with an
E2 code
.
When the pressure switch closes calculate the Water Debit Constant time for filling up 2.7
liters.
