2.4. Installing (changing) the expanding head (16) in REMS Ax-Press 15
(Fig. 6)
Remove the battery. Fit the expander (15) (accessory) To do so, clean the
connecting surfaces, attach the expander, and tighten the two fillister-head
screws. Grease the cone of the expanding mandrel (18) lightly. Screw the
selected e xpanding head as far as it will go onto the expander. Only use system-
specific expanding heads. Expanding heads have a letter to identify the
compression sleeve system and a number to identify the size. Consult and
comply with the instructions for installation and fitting of the s ystem's manu-
facturer. Never use non-matching expanding heads (compression sleeve system,
size) for expansion work. The press joint could be unserviceable, and both the
machine and the expanding heads might be damaged.
NOTICE
Ensure that the compression sleeve has sufficient clearance from
the e xpanding head during the expansion process, otherwise the expanding
jaws (17) might become bent or broken.
For pressing jobs in cramped places, the expander attachment can be r emoved.
2.5. Installing (changing) the expanding head (16) in REMS Akku-Ex-Press
Q & E ACC and REMS Power-Ex-Press Q & E ACC (Fig. 8, 9)
Pull out the mains plug or remove the battery. Only use genuine expanding
heads for Uponor Quick & Easy. Consult and comply with the instructions for
installation and fitting of the system's manufacturer. Never use non-matching
expanding heads (system, size) for expansion work. The joint could be unserv-
iceable, and both the machine and the expanding heads might be damaged.
Grease the cone of the expanding mandrel (18) lightly. Screw the selected
expanding head as far as it will go onto the expander. Read and follow the
installation and assembly instructions of the system manufacturer. REMS
expanding heads P and Cu are unsuitable for the REMS Akku-Ex-Press Q & E
ACC and REMS Power-Ex-Press Q & E ACC pipe expanders and may therefore
not be used.
Changing the expanding device on the REMS Power-Ex-Press Q & E ACC
Pull out the mains plug. Unscrew the expanding device from the REMS Power-
Ex-Press Q & E ACC. Screw on the new expanding device to the stop and
tighten by hand.
2.6. Mounting (changing) the expanding head (16) on the REMS Akku-Ex-Press
Cu ACC (Fig. 12)
Remove the battery. Grease the cone of the expanding mandrel lightly. Screw
the selected expanding head onto the expanding device to the stop. The
expanding device must now be set so that the thrust of the drive machine is
taken up by the drive machine and not the expanding head at the end of the
expanding. Unscrew the expanding device complete with screwed on expanding
head from the drive machine for this. Let the feed piston run forward as far as
possible without the machine switching into reverse. In this position the expanding
device complete with screwed on expanding head must be screwed onto the
drive machine until the segments of the expanding head are fully open. The
expanding head must be secured with the locking nut in this position.
2.7. Mounting (changing) the expanding head (16) on the REMS Akku-Ex-Press
P ACC (Fig. 11)
Remove the battery. Grease the cone of the expanding mandrel (18) lightly.
Screw the selected expanding head onto the expanding device to the stop.
Only use system-specific expanding heads. Expanding heads are labelled with
letters to identify the compression sleeve system and with a number to identify
the size. Read and follow the installation and assembly instructions of the
system manufacturer. Never expand with the wrong expanding heads (compres-
sion sleeve system, size). The connection could be useless and the machine
and expanding heads could be damaged.
3. Operation
3.1. Radial presses (Figs. 1 to 6 and 16 to 19)
A test pressing with inserted press fitting must be made with the drive machine
and the respectively inserted pressing tong, pressing tong Mini, pressing ring
with adapter tong before every use. The pressing tong (1), pressing ring (20)
or pressing segments (21) must close fully. Full closure of the pressing jaws
(10), pressing rings (20) or pressing formers (21) both at their tips (Fig. 1, and
Fig. 16 to 19 at "A") and on the opposite side (Fig. 1 and Fig. 16 to 19 at "B")
can be observed after completing the pressing. Check the tightness of the
connection (observe national specifications, standards, regulations, etc.)
The pressing tong, pressing tong Mini, pressing ring and adapter tong, and
especially the pressing contour (11 / 22) of both pressing jaws (10) or all 3
pressing segments must be checked for damage and wear before every use.
Damaged or worn pressing tongs, pressing tongs Mini, pressing rings or adapter
tongs may no longer be used. There is otherwise a risk of incorrect pressing
or accidents.
If during closing of the pressing tongs, pressing tongs Mini or pressing rings a
marked ridge is created on the compression sleeve, the pressing may be
defective or not tight (see 5. Trouble).
For preventing damages make sure to avoid operating situations like exempla-
rily shown in Fig. 13 through 15, that no distortion between pressing tongs,
pressing tongs Mini, pressing rings, adapter tongs, fitting and drive unit occurs.
3.1.1. Working procedure
Press the pressing tongs, pressing tongs Mini (1) together manually until they
can be pushed over the press fitting. Always position the drive unit with the
pressing t ongs on the press fitting at right angles to the pipe axis. Release the
pressing tongs so that they close around the press fitting. Hold the drive unit
by the housing grip (6) and the pistol grip (9).
Place the pressing ring (20) around the pressing fitting. Insert the pressing tong
(19) into the drive unit and lock the tong retaining bolt. Press the pressing tong
(19) together with your hand so that the adapter tong can be placed on the
pressing ring. Release the adapter tong so that the adapter tong is tightly applied
to the pressing ring and the pressing ring to the pressfitting.
In the case of the REMS Power-Press E, set the rotation direction lever (7) to
the right (advance) and press the inching switch (8). Keep the inching switch
(8) pressed until the pressing is finished and the pressing tong or pressing ring
is closed. Set the rotation direction lever (7) to the left (return) and press the
switch (8) until the press rollers have retracted and the slipping clutch r esponds.
Do not put unnecessary loads on the slipping clutch.
In the case of the REMS Power-Press and REMS Akku-Press, keep the inching
switch (8) pressed until the pressing is finished and the pressing tong or pressing
ring is completely closed. This is indicated by an acoustic signal (clicking).
Press the reset button (13) until the press r ollers (5) are fully retracted.
In the case of the REMS Mini-Press ACC, REMS Akku-Press ACC and REMS
Power-Press ACC, keep the inching switch (8) pressed until the pressing is
finished and the pressing tong or pressing ring is completely closed. After
completion of p ress i ng, the drive unit switches automati c ally to return (forced
return).
Press the pressing tongs together with your hand so that they can be removed
from the pressfitting together with the drive unit. Press the adapter tong together
with your hand so that they can be removed from the pressing ring together
with the drive unit. Open the pressing ring by hand so that it can be pulled off
the pressfitting.
3.1.2. Operating safety
In the case of the REMS Power-Press E, the pressing operation is ended by
releasing the inching switch (8). For the mechanical safety of the drive units,
a torque-controlled safety slipping clutch is operative in both end positions of
the press rollers.
The REMS Power-Press and REMS Akku-Press ends the pressing opera t ion
automatically, emitting an acoustic signal (clicking). The REMS Mini- P ress ACC,
REMS Akku-Press ACC and REMS Power-Press ACC ends the pressing
operation automatically, emitting an acoustic signal (clicking), and returns
automatically (forced movement).
NOTICE
A perfect pressing is only produced with full closure of the
pressing tongs, pressing tongs Mini, pressing ring or pressing segment.
Full closure of the pressing jaws (10), pressing rings (20) or pressing
segment (21) both at their tips (Fig. 1 and Fig. 16 to 19 at "A") and on the
opposite side (Fig. 1 and Fig. 16 to 19 at "B") can be observed after
completing the pressing. If a visible burr is created on the pressing sleeve
when closing the pressing tongs, pressing tongs Mini, pressing ring or
pressing segment, the pressing may be faulty or leaking (see 5. Trouble).
3.1.3. Working safety
To ensure safe working, the drive units are equipped with a safety inching
switch. This permits immediate switching off of the drive units at any time,
particularly if a potential hazard arises. The drive units can be switched to the
return function in any position.
3.2. Axial presses (Figs. 6, 7, 10)
3.2.1. Pressing with the REMS Ax-Press 15 and Ax-Press 40 (Fig. 6, 7)
Place the preassembled compression sleeve fitting inside the pressing heads
(14). Hold the drive unit by the housing grip (6) and the pistol grip (9), and keep
the inching switch (8) pressed until the compression sleeve is in contact with
the collar of the compression sleeve fitting. This is also indicated by an acoustic
s ignal (clicking). Press the reset button (13) until the pressing heads (14) are
f ully retracted.
Pressing with REMS Ax-Press 25 ACC, REMS Ax-Press 25 L ACC
(Fig. 10)
Hold the drive machine either with one hand on the switch handle (9) or two
hands on the housing handle (6) and the switch handle (9). Keep the inching
switch (8) pressed until the compression sleeve is touching the collar of the
compression sleeve connector. The drive machine then switches automatically
to return (forced return).
With the compression sleeve system IV, various pressing heads are needed
for one pipe size. Consult and comply with the instructions for installation and
fitting of the system's manufacturer.
In the case of the compression sleeve system RV, preliminary and final pressing
is necessary, i.e. the pressing heads must first be inserted with a wide spacing
of the receptacles for the compression sleeve fitting. Before a second pressing
operation, the pressing heads are set to a narrow spacing of the receptacles
for the compression sleeve fitting by a 180° r otation. Consult and comply with
the instructions for installation and fitting of the system's manufacturer.
For compression sleeve systems which use the compression heads UNI and
Basic, not all compression sleeve connectors can be pressed with the REMS
Ax-Press 25 ACC. Therefore the REMS Ax-Press 25 L ACC must be used.
Note that the compression heads must be inserted into the pressing machine
in such a way that the pressing can be done in one stroke if possible. This is
