WTC 600 LP / MP OPERATION OF THE SYSTEM
Service Handbook 08.2004
3.4.3.8 Initial startup
- Set the equipment to the operation operating mode (see 3.4.4)
- Set the drinking water capacity to 600 l/h
- For very cold water, the drinking water capacity of 600 l/h is not achieved: Then adjust the
maximum pump pressure of 21 bar (MP) or 14 bar (LP)
- Adjust the concentrate capacity to 200 l/h (for very cold water possibly somewhat more)
Closing the pressure control valve (11/1) Closing the concentrate control valve
(11/8)
Pump pressure and concentrate pressure Pump pressure and concentrate pressure
increase increase
Drinking water amount increases Drinking water amount increases
Concentrate amount increases Concentrate amount decreases
Conducting capacity increase Conducting capacity increase
Table 20 Operating performance of the reverse osmosis when changing the pressure control
and concentrate control valve
For all changes of the settings to the system, the following values may not be
exceeded under any circumstances:
- Maximum pump pressure 21 bar (MP) or 14 bar (LP)
- Drinking water amount, 650 liters per hour maximum.
Untreated Drinking water Concentrade Yield
water capacity capacity
1200 l/h 600 l/h 600 l/h 50%
800 l/h 600 l/h 200 l/h 75%
Table 21 Typical yields at maximum drinking water capacity and untreated water temperature
of 15 °C
The drinking water capacity must never be set at more than 650 l/h, meaning that at
higher / lower feed-water temperature, the pump pressure and concentrate pressure
must be decreased / increased respectively by means of the ball valves (compare
figure 11).
Check the conductance value according to the reading on the display.
Demineralization rate: 94 – 99 %.
- Switch off the system at the main switch.
- Connect drinking water line in tank.
- Switch on the system at the main switch: Drinking water is produced and fills the tank.
- Tank filled: The level float switches off the solenoid valve and the pump until the switch of the
level float signals empty and the RO system switches on again.
