3.7. Operation of compressed air tools

Compressed air tools can be operated up to a max. air requirement of 230 Nl/

min can be operated directly from the compressed air vessel. The air pressure

supplied by the compressed air vessel can be checked on the compressed air

vessel pressure gauge (Fig. 4 (30)). The compressor can be switched off at

any time with the compressor emergency stop button (Fig. 4 (29)). The adjusting

wheel must be raised to set the pressure of compressed air tools (Fig. 4 (31)).

The set pressure can be read at the compressed air tools pressure gauge (Fig.

4 (32)).

3.8. Transport and storage

Completely drain the electronic flushing and pressure testing unit, disinfection

and cleaning unit as well as the hoses to avoid damage; store at ≥ 5°C and

dry. Water residue from pressure testing with water, from flushing, disinfection,

cleaning and preservation should be removed with the compressor/water

connections connecting hose (Fig. 8 (38) (accessory) after every use. This

connected to the compressed air tools connection on one side (Fig. 4 (28)) and

respectively to the flushing supply (Fig. 1 (14)) or the pressure test with water

supply on the other side (Fig. 1 (24)). See 3.7 for the further procedure.

Protect

ROLLER’S Plus TW-D Color, ROLLER’S Plus H-R and ROLLER’S Plus

H-K against frost, heat and direct sunlight. Keep containers tightly closed and

store in a cool, well-aired place.

The water connections on the device and the hoses should be sealed by caps

or plugs to prevent contamination.

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. Replace damaged hoses

and seals. Keep all the hose connections clean. Remove water residue from

flushing, disinfection, cleaning, preservation or from the pressure test with

water with the compressor/water connections connecting hose (Fig. 8 (38)

(accessory) after every use. Seal machine connections and hose ends with

caps or plugs. Rinse the disinfection and cleaning unit (Fig. 7), without bottle

(Fig. 7 (21)) with clean water after every use.

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)). Remove the protective hood for the following maintenance

work. Loosen the 6 screws of the protective hood (Fig. 1 (37)).

Empty the tank of the condensation and particle filter in the electronic flushing

and pressure testing unit with compressor regularly. The filter cartridge must

be cleaned and replaced if necessary. Clean the air filter of the compressor

regularly.

Change the fine filter cartridge (Art. No. 043054) of the fine filter (Art. No.

115609) regularly.

It is not necessary to calibrate the control elements of the ROLLER’S Multi-Con-

trol. It is recommended to check the pressure gauge every 2 years. The applied

pressures can be checked if necessary by additionally connecting a suitable

pressure gauge (see Accessories 1.2).

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 the machine regularly especially when it has not been in use for a long

time. Clean plastic parts (e.g. housing) only with 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.

4.2. Inspection / Repair

WARNING

Pull out the mains plug before carrying out maintenance or repair work!

This work may only be performed by qualified personnel.

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.albert-roller.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:

Remedy:

● On/Off button (Fig. 2 (4)) pressed too briefly.

● Press On/Off button for about 2 s, then release.

● PRCD fault current circuit breaker (Fig. 1 (1)) is not switched on.

● Switch on PRCD fault current circuit breaker as described in 2.1..

● Mains lead/PRCD defective.

● Have the mains lead/PRCD changed by qualified personnel or an authorised

ROLLER customer service workshop.

● Electronic flushing and pressure testing unit with compressor defective.

● Have the electronic flushing and pressure testing unit with compressor

checked/repaired by an authorised ROLLER customer service workshop.

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:

Remedy:

● Compressor emergency stop button (Fig.4 (29)) is switched off.

● Switch on compressor by pulling out the emergency stop button.

● Electronic flushing and pressure testing unit with compressor defective.

● Have the electronic flushing and pressure testing unit with compressor

checked/repaired by an authorised ROLLER customer service workshop.

5.3. Fault: The necessary minimum flow velocity is not achieved in the flushing program.

Cause:

Remedy:

● Stop tap of the house connection is only partly open.
