AN Danger! Risk of getting burnt from hot oil and hot system components. Let pump cool down for 15 minutes before making oil change. L Important! Used oil may be disposed of only atthe collecting points designated for this purpo- se. Please hand in used oil resulting from the oil change at such à place. Pollution of the environment with waste oil is a punisha- ble offence. Oil types and oil quantities: see Technical Data. Carry out the oil change as follows: = Hold container for used oil ready. = Remove cover of oil reservoir (@). = Screw out threaded oil-drain plug @ and catch used oil. = Screw in threaded oil-drain plug @. = Pour in new oil slowly up to position “Max” on oil reservoir. = Put on cover of oil reservoir (). = Convey used oil to the designated col- lection point.

AN Danger! Explosion hazard through flammable gases! Smoking is prohibited when carrying out decalcification procedures. Ensure adequa- te ventilation. Caution! Acid hazard! Protective goggles and gloves must be worn. Lime deposits throughout the water lines of the high-pressure system create increased pipe-run resistance and may result in the failure of calcified components. According to official regulations, only ap- proved boiler scale dissolvants (de-scaling acid) with test mark may be used. For scale removal in the high-pressure sy- stem, the use of KÂRCHER scale dissol- vants should be given preference (RM 100 ASF, hydrochloric acid-free, part no. 6.287-008, or RM 101 ASF, containing hydrochloric acid, part no. 6.287-013). These products are balanced for use in conjunction with the materials present throughout the system. After decalcification we recommend neutralising the remaining acid residues by flushing the system with an alkaline solution (pH value 7-8). The instructions for use and accident pre- vention regulations (dilution according to la- bel specifications), and in particular VBG1, 84, 14, and 44-47 must be observed.

HD 600 / 1000 / 1400 C(H) E. Maintenance English Proceed as follows: Begin by decalcifying the float reservoir: Close water supply. Remove the float reservoir lid. Remove the hose connecting the pump suction side with the float reservoir, pump side. Block the free end of the hose. Pour in 7-percent de-scaling solution. After the conclusion of decalcificati- on, remove all scale residues from the reser- voir! Decalcifying high-pressure system: Disconnect high-pressure hose from water supply inlet and hang into float reser- voir. Next, use the decalcifying acid soluti- on pre-mixed in the float reservoir for short- term system operation in circulation (idle pressure) mode. Allow chemicals to activa- te, and conclude by flushing the system. 5.959-490 À 12578 (12/99)

Possible ways in which the unit can be set up are as follows: # Mounted on the wall # Setup on the ground using the Stand accessory kit (optional) If wall mounting is used, the wall should be tested for its load-bearing capability. The supplied mounting materials are suitable for walls made of concrete or solid brick with a wall thickness from 11.5 cm. Information on mounting on other types of wall construction can be gained from “Planning manual HD- ST”. (For drill-hole layout see specifications table). If the unit is set up using the Stand acces- sory kit, the procedure is described in the supplied assembly instructions. AN Danger! Risk of injury from the water jet or parts flying off. The screw unions of all connecting hoses and pipelines must be tight. Use only unda- maged and manufacturer-recommended screw unions and high-pressure hoses.

The water connection, the high-pressure network and the electrical connections may be carried out only by authorised skilled personnel in compliance with local regulati- ons. The water supply and the power con- nection must be made available for conti- nuous operation. The prescribed connected values can be seen in the technical data. The water quality must meet the require- ments as specified in section “A.13 Proper use of the equipment”. In Germany the following regulations apply: m VDMA Einheitsblatt 24416 directive “Festinstallierte Hochdruck Reinigungs- systeme” (Fixed-installation high-pressu- re cleaning systems) m VDE regulations = Local power-supply company regulations The water supply must be equipped with a shutoff valve, and must be connected with the high-pressure by means of a flexible high-pressure hose. Insufficient supply line cross section or insufficient admission pres- sure will result in water starvation. In the event of excessive admission pres- sure or the occurrence of pressure peaks in the mains network, the installation of a pressure regulator upstream of the system is mandatory. A water drain must be present at the instal- lation site.

3. High-pressure Installation

The link between the fixed-installation pipe network and the system must be executed in the form of a flexible high-pressure hose connection. The permanent pipe network installation must consist of as many straight runs as possible. All high-pressure tubing must be installed pursuant to regulations, using vibration-dampened strain relief and fixed pipe or tubing clamps, while allowing for longitudinal expansion/contraction due to the effects of temperature and pressure.

To keep pressure losses in the high-pres- sure lines as low as possible, the following recommendations should be used as man- datory guidelines: Flow rate Pipeline Hose line 600 l/h DN 15 (2") DN 8 1000 l/h DN 15 (2") DN 8 1400 l/h DN 15 (2") DN 8 It should be understood that the above gui- delines still require additional allowances for the overall tubing length, the number of directional changes and armatures.

4. Mounting detergent reservoirs

A Danger! Danger of being poisoned, suffering acid burns and fire hazard as a result of impro- per handling of detergents. Store detergents in a place which is inac- cessible to children. Be certain to observe the instructions on the packaging. The cleaning agent reservoir should be set up in such a way that the base of the reser- voir is not more than 2 m below the unit.

5. Hard-water Treatment

An over-high hardness of water (>15° dH) can lead to deposits and functional faults. Where hardness of water is relatively high, use the Softener accessory kit.

6. Preparations for Commissioning

m Thoroughly rinse entire HD system Check entire HD system for correct assembly and lack of leaks. m Only for HD xxxx CH units: Push and secure enclosed overflow hose incl. hose clip on hose liner at float tank. Conduct hose end through the opening located in the base of the plant. # Complete electrical connections in accor- dance with the Specifications contained in the Operating Instructions. # Check the function of decalcifying com- ponent (if required). # Check water supply for required delivery volume and maximum allowable tempe- rature. m Check pump oil level. Remove threaded plug from oil reservoir. mBefore using for the first time, cut off the tip of the cover of the oil reservoir on the water pump. m Only for HD xxxx CH: Check direction of rotation of the precompression pump. Direction of rotation has to be in unison with the arrow on the housing. # Make adjustment settings as described in section B.4.
