When operating, the electric pressure-testing pump must stand in an hori-
•
zontal position and be in a dry condition.
Do not switch-in the electric pressure-testing pump when the „Press" pres-
•
sure-regulating valve is closed. And do not operate the pressure-testing
pump for a longer period of time as well. Otherwise, the pressure-testing
pump will get overheated.
Do not direct any liquid jets onto the electric pressure-testing pump. When
•
cleaning it, adhere to the same requirement as well.
Do not pump any combustible fluids, acid solutions, or dissolvents.
•
Protect electric pressure-testing pump against frost. If necessary, let run idle
•
for approx. 1 min so that the remaining water runs out or suck glycol/water
mixture.
Before starting any servicing work, draw out the mains plug, and make un-
•
pressurerized the pressure-testing pump. Before dismounting the pressu-
re vessel, make it unpressurerized. Otherwise, when dismounting, the re-
maining pressure can catapult pieces out of the unit.

2. Initial operation
2.1. Electric connection
Care must be taken to the power-line voltage! Before connecting the
pressure-testing pump, you must check and make sure that the electric
voltage indicated on the nameplate complies with the line / mains voltage
supplied by the power station. Put the (1) switch into the „0" position. When
employing an extension cable, make sure that the required cross-sectio-
nal area ( 1,5 mm
2
) will be used. If working in an humid environment,
then it will be required that the pressure-testing pump is operated via a
30-mA current-operated earth-leakage circuit breaker.
2.2. Suction hose
Fasten the (2) suction hose by means of screws at the (3) connecting
piece. Do not kink the suction hose. Pump clean fluids only. Do not re-
move the (4) suction filter at the suction hose. Make sure that the pres-
sure-testing pump does not suck in any air. Otherwise, its function will be
affected.
2.3. High-pressure hose
Fasten the (5) high-pressure hose by means of screws at the (6) connec-
ting piece.

5.1. Malfunction: The pressure-testing pump is running. However, it is
Fill and de-air the sanitary and/or heating facility. Place the electric pressure-
testing pump onto an horizontal and smooth surface. Lay the (2) suction
hose together with the (4) suction filter into a container filled with approx.
10 l of water. Connect the (5) high-pressure hose with the sanitary and/or
heating facility which has to be leak tested. Open both the (7) „Test" stop
valve and the (8) „Press" pressure-regulating valve. In order to switch in
the pressure-testing pump, actuate the (1) switch. When turning the (8)
„Press" pressure-regulating valve, the desired pressure can be adjusted
at the (9) manometer, as described below: When turning into clockwise
direction, the pressure will be increased. However, when turning into coun-
ter-clockwise direction, it will be decreased.
If required, de-air the sanitary and/or heating facility repeatedly. After any
de-airing action, repeat the pressure testing as well. As soon as achie-
ving the desired pressure, the following actions must be executed:, close
the (7) „Test" stop valve, open the (8) „Press" pressure-regulating valve,
and switch off the pump.
Provided that both the (10) connecting piece with manometer (Don't
exceed maximum pressure indication of the manometer!) and the stop
valve between the electrical pressure-testing pump and the sanitary and
heating facility under testing have been mounted, the following possibility
will exist: while testing the pressure, the electric pressure-testing pump
can be separated from the sanitary and heating facility being under leak
test. Note: the stop valve is an accessory part. In this case, after reaching
the desired pressure, the following measures must be taken: close the
stop valve at the (10) connecting piece, open the (8) „Press" pressure-
regulating valve, switch off the pump, and detach the high-pressure hose
at the (10) connecting piece as well.
Do not pump any combustible fluids, acid solutions, or dissolvents. Note
permitted ratings pH, viscosity and temperature of fluids (see 1.2).
Lay the (2) suction hose with the (4) suction filter into the container with
the fluid which must be pumped. Lay the (5) high-pressure hose into the
container, or to the facility which has to be filled. Close the (8) „Press"
pressure-regulating valve, and open the (7) „Test" stop valve. Switch in
the pump (1), and pump the fluid.
After finalizing the operation of the unit, open both the (8) „Press" pressure-
regulating valve and the (7) „Test" stop valve. Subsequently, rinse the
pump with clean water for a few minutes.
Before inspecting the unit, draw out the mains plug! Before every using
of the machine, examine the high-pressure-hose for damages. Keep cle-
an the (4) suction filter!
Before maintaining the unit, draw out the mains plug! Change the oil af-
ter every 150 operating hours. For this, lay the pressure-testing pump on
its side area, detach the (11) screws at both the housing shells. Then,
open and detach the housing shells. Open the (12) plastic-material plug
fittings at the bottom side of the pump. Drain-off the oil. Now, fill in approx.
0.15 l of new SAE-30 oil. When the pump is leaking oil, the complete pres-
sure-testing pump must be sent for inspection and/or repair to a service
station authorized by ROLLER.
Before repairing the unit, draw out the mains plug! This work may only be
carried out by skilled labor and trained personnel as well.
not creating any pressure.
Cause:
The „Press" stop valve has not been closed yet.
•
The pressure-testing pump has been sucking air.
•
The filter at the suction hose has been plugged.
•
The pressure-testing pump has become defective.
