Maintenance - REMS Multi-Push SL Betriebsanleitung

eng
The water connections on the tool and the hoses should be sealed by caps or
plugs to prevent contamination.

4. Maintenance

4.1. Inspection
WARNING
Pull out the mains plug before inspection! Check hoses and seals for damage
before every use. Do no used damaged hoses and seals.
4.2. Maintenance
WARNING
Pull out the mains plug before maintenance work! The tank of the conden-
sation and particle filter in the electronic flushing and pressure testing unit with
compressor must be checked regularly and emptied if necessary. The filter
cartridge must be cleaned and replaced if necessary. Loosen the 6 screws of
the protective hood (Fig. 1 (37)) to do this, remove the protective hood. Keep
all the hose connections clean. Open both condensation screw plugs (Fig. 1
(34)) from time to time to drain condensation from the compressed air tank
(Fig. 1 (35)).
5. Fault
NOTICE
If faults occur, first check whether the respective latest version software (Ver. Software) is installed on the input and control unit. Select the Settings menu and then
Device data to display the version software. The latest version software (Ver. Software) for the input and control unit is available by USB stick as a download under
www.rems.de → Downloads → Software. Compare the number of the version software with the latest version software number and install the latest version software
on the input and control unit by means of a USB stick if necessary. See 2.3 for the further procedure.
5.1. Fault: Electronic flushing and pressure testing unit with compressor does not switch on after pressing the On/Off button (4).
Cause:
● On/Off button (Fig. 2 (4)) pressed too briefly.
● PRCD fault current circuit breaker (Fig. 1 (1)) is not switched on.
● Mains lead/PRCD defective.
● Electronic flushing and pressure testing unit with compressor defective.
5.2. Fault: Compressor will not start although there is low or no pressure in the compressed air tank (see the display on the compressed air tank pressure gauge
(Fig.4 (30)).
Cause:
● Compressor emergency stop button (Fig.4 (29)) is switched off.
● Electronic flushing and pressure testing unit with compressor defective.
5.3. Fault: The necessary minimum flow velocity is not achieved in the flushing program.
Cause:
● Stop tap of the house connection is only partly open.
● Fine filter (Fig. 3 (12)) is contaminated.
● Not enough tapping points opened.
● Hoses connected incorrectly.
● Wrong defaults entered.
● Valves blocked, considerable, irremovable encrustations in the pipes.
5.5. Fault: The set pressure (p refer) is not reached in the test with compressed air or compressed air pump programs.
Cause:
● Installation or compressed air hose (Fig. 4 (23)) leaking.
● No or too little pressure in the compressed air tank.
● Electronic flushing and pressure testing unit with compressor defective.
5.6. Fault: The set pressure (p refer) is not established in the test with water program (only Multi-Push SLW).
Cause:
● Suction/pressure hose (Fig. 1 (13)) or high-pressure hose (Fig. 4 (26))
leaking.
● Hydro-pneumatic pump does not build up pressure.
● Stop tap of the water supply is closed or only partly open.
● No or too little air pressure in the compressed air tank.
● Electronic flushing and pressure testing unit with compressor defective.
5.7. Fault: The pressure in the pipe to be tested is not relieved after running the test with water programs or during the test with water
B, P+M.
Cause:
● Pressure relief water drain (Fig. 4 (27)) is soiled or defective.
● Electronic flushing and pressure testing unit with compressor defective.
5.8. Fault: The date and time must be reset every time the electronic flushing and pressure testing unit with compressor is switched on.
Cause:
● Battery depleted.
In order to ensure that the date and time remain saved at all times, the button
cell (Lithium CR1220, 3 V) on the back of the operating panel (Fig. 1 (36))
should be changed about every two years. Loosen the 6 screws of the protec-
tive hood (Fig. 1 (37)) to do this, remove the protective hood. Then loosen the
4 screws of the operating panel and change the button cell on the back of the
operating panel.
Clean plastic parts (e.g. housing) only with REMS CleanM machine cleaner
(Art. No. 140119) or a mild soap and a damp cloth. Do not use household
cleaners. These often contain chemicals which can damage the plastic parts.
Never use petrol, turpentine, thinner or similar products for cleaning.
Make sure that liquids cannot get inside the electronic flushing and pressure
testing unit with compressor.
4.3. Repair
WARNING
Pull out the mains plug before doing maintenance work! This work may
only be performed by qualified personnel.
Remedy:
● Press On/Off button for about 2 s, then release.
● Switch on PRCD fault current circuit breaker as described in 2.1..
● Have the mains lead/PRCD changed by qualified personnel or an authorised
REMS customer service workshop.
● Have the electronic flushing and pressure testing unit with compressor
checked/repaired by an authorised REMS customer service workshop.
Remedy:
● Switch on compressor by pulling out the emergency stop button.
● Have the electronic flushing and pressure testing unit with compressor
checked/repaired by an authorised REMS customer service workshop.
Remedy:
● Fully open the stop tap.
● Clean or change the fine filter and filter cartridge.
● Open the appropriate number of tapping points.
● Connect hoses as shown in Fig. 3.
● Check defaults, correct if necessary. Restart the program.
● Clean/change valve(s). Clear encrustations.
Remedy:
● Check installation for leaks. Change the compressed air hose.
● See 5.2. Fault:
● Have the electronic flushing and pressure testing unit with compressor
checked/repaired by an authorised REMS customer service workshop.
Remedy:
● Change suction/pressure hose or high-pressure hose.
● Connect suction/pressure hose between the house connection and the
pressure test with water supply, see 2.6.2.
● Fully open the stop tap.
● Hydro-pneumatic pump requires compressed air, see 5.2. Fault:
● Have the electronic flushing and pressure testing unit with compressor
checked/repaired by an authorised REMS customer service workshop.
Remedy:
● Clean the pressure relief water drain or have it replaced by qualified personnel
or an authorised REMS customer service workshop.
● Have the electronic flushing and pressure testing unit with compressor
checked/repaired by an authorised REMS customer service workshop.
Remedy:
● Change battery. See 4.2.
