Therefore carry out the adjustment at the pressure control valve (14) and at the concentrate control valve (13) only in small steps, and wait until checking the respective effect. (1) Flow of drinking water has decreased from _____ to _____ l/h Read off the amount of drinking water at the flow meter (42) and compare with the value taken when starting operation (see operational start-up record). If the flow of drinking water has decreased to _____ l/h , the following fine adjustment is to be carried out. If the fine adjustment does not lead to an increase in the drinking water flow, the Karcher Service must be contacted. • Slowly shut the pressure control valve (14) in clockwise direction until the desired amount is almost reached at the flow meter (42). • Slowly shut the concentrate control valve (13) in clockwise direction until the respective set value is reached on both flow meters for concentrate (43) and drinking water (42). Notice: The quantity of concentrate will increase. This is correct. • Carry out a readjustment on both valve levers, if required. (2) Conducting capacity of the drinking water has increased from _____ to _____ .S/cm 42 11 13 14 10 12 43 i Small increases of the drinking water conducting capacity do not influence the drinking water quality. On the display of the control panel (10), read the current drinking water conductance value and compare with the value taken when starting operation (see operational start-up record). If the drinking water conductance value has increased to _____ .S/cm, the following fine adjustment is to be carried out. If the fine adjustment does not lead to a decrease of the drinking water conductance value, the Karcher Service must be contacted. • Open the concentrate control valve (13) in counterclockwise direction in small steps until the conductance capacity has reached the set value. • Shut the pressure control valve (14) in clockwise direction in small steps until the drinking water amount in the viewing glass (42) has reached the set value. WTC 600 LP / MP Version 06/05 Maintenance and Care Notice: The amount of concentrate will increase. This is correct. Observe the maximum pressure of 21 bar (MP) or 14 bar (LP) at the manometer (11)! • Repeat the adjustment steps, if required. The original drinking water amount may possibly not quite be reached. (3) The difference between pump and concentrate pressure has increased by more than _____ bar • Read the values at the manometer for the pump pressure (11) and for the concentrate 3.2.6 Mixing the Chemicals pressure (12), and determine the differential pressure. • Compare the differential pressure with the value taken when starting operation (see operational start-up record). If the differential pressure has increased by more than _____ bar, then the RO filter membrane is clogged. Readjustment is no longer possible. Stop the drinking water production and notify the Karcher Service. When working with chemicals, always wear protective clothing. Values for the metering of the various chemicals result from the untreated water analysis and the system capacity. Upon starting operation, the Karcher service technician enters the required metering amounts for your equipment into the following metering table. (1) Metering Table i Metering Container Chemical Item No. Metered Amount of the Chemical [ml] per 10 l Metering Solution Pre-RM 852 sterilization agent * 6.291-772.0 chlorination Chlorinated lime * 6.291-505.0 Pre-flocculation Ferrifloc 6.294-703.0 Anti Scalant RM 5000 hardness stabilizer 6.290-991.0 Post RM 852 sterilization agent * 6.291-772.0 chlorination Chlorinated lime * 6.291-505.0 * These chemicals can each be used alternatively Consumption Materials Version 06/05 WTC 600 LP / MP (2) Metered Addition For mixing of the chemical, only unchlorinated drinking water may be used. This water is taken from the drinking water sampling valve (44). 44 The metered addition is carried out dependent of the level in the metering container. Completely emptied metering container: • Fill 10 l of drinking water into the metering container. • With a measuring cup, measure the 7.5 -fold amount mentioned in the “10 Liter Water” column of the respective chemical and fill into the container. • Fill the container with drinking water to the “75 l” mark and mix according to Section 3.1.2. Consumption Materials Partially emptied metering container: • Read off the level of the fluid with help of the scale at the metering container, e. g., 35 l. • Determine the quantity to be refilled by subtracting the read level from the 75 l. Example:75 l- 35l = 40l. • Determine the required amount of the respective chemical from the metering table. Example: 4 x the amount for 10 l water. • Measure the determined amount of the respective chemical and fill into the container. • Refill amount of water to the “75 l” mark and mix in accordance with Section 3.1.2. 3.3 Switching Off the Equipment If the equipment is not operated for periods exceeding 14 da...
