4.2. Brief description of the important features of the unit

- The hydraulic unit incorporates an automatic retraction which
returns the drive rolls into its starting position when the
maximum operating pressure is reached.
- The unit is equipped with a special brake which stops the
forward motion of the drive rolls when the trigger (Pos.-# 1) is
released.
- The unit is equipped with a double piston pump which is
characterised by a rapid approach of the drive rolls towards the
jaws (Pos.-No. 10) and a slow pressing motion.
- The pressing head (Pos.-# 4) can be smoothly turned by 360°
around the longitudinal axis in order to gain better access to tight
corners and other difficult working areas. (see Picture 3+4)
5. Remarks in respect of the determined use
First the mains voltage must checked whether it matches with the
required tool voltage and then the mains plug must be plugged into
the socket. Since the UNP 2 is dooble insulated you can also use a
not grounded socket to connect the tool the te mains supply.

5.1. Operation of the units

First the mains voltage must checked whether it matches with the
required tool voltage and then the mains plug must be plugged into
the socket. Since the UNP 2 is dooble insulated you can also use a
not grounded socket to connect the tool the te mains supply.
After having selected the right pressing jaw for the intended
application the jaw must be examined in terms of possible damage,
dirt in the compression area and ware. When using competitor
products the user has to make sure that the jaw complies with our
tool. To insert or change the pressing jaw please follow picture 6-
11.
After mounting the fitting on the tube the pressing jaws will be
opened by pushing the rear end of the pressing jaw together while
the jaw has to be positioned on the fitting. (Pls. see also picture 5
Pos. E)
A pressing procedure will be initiated by actuating the trigger
(Pos.-#. 1, Picture 2 Pos. C). The pressing process is defined by the
closing motion of the pressing jaws. The drive rolls on top of the
ram close the pressing jaws scissors like.
Attention
The user has to make sure that the lock pin (Pos. 3) is
properly engaged
Attention
A necessary condition for a permanently leaking free
connection is that the pressing cycle has to be completed
which means that the pressing jaws completely closed at
the tip as well as the T-link.
Attention
The assembly of gas pipes in gas distribution lines is
prohibited unless the system provider gives an explicid
permission to use this tool on special gas fittings.
Attention
The pressing procedure can be interrupted at any moment by
releasing the trigger.
Attention
The user has to check by optical means whether the pressing
jaws are completely closed.
Attention
If a pressing cycle has been interrupted the fitting has to be
either dismantled or pressed a second time.
Attention
Do not use the power cable for unintended purposes.
Don't carry the tool by the power cable and don´t use the
cable to pull the plug out of the power receptacle.
Attention
When working outdoors, use only approved extension cables.
The user needs to make sure that the pressing jaws are completely closed
and that there are no foreign objects (e.g. plaster or stone fractions)
between the pressing jaws.
In case of error or emergency push retract button (Pos. 2, Picture 2 Pos.
B) to return the drive rolls into starting position.
The drive rolls retract automatically and return into the starting position
after the maximum operating pressure has been reached enabling the
user open the pressing jaw.
Attention
Before changing the pressing pull the plug out of the
socket to avoid unintentional operation.

5.2. Explanation of the application range

The UNP 2 is a hand guided pressing tool to mount fittings on multi
Layer, copper and steel type plumbing tubes with ∅ 12 to 54 mm and
with the pressing chain (Pos.-# 12c) even up to 75 mm. The unit is not
supposed to be restrained in a vise. It is not allowed to use the tool in a
stationary application. Complying certain conditions the unit can be
operated stationary with our presentation support EKST. The conditions
can be taken from the instruction manual of the EKST.
The tool is not designed for continued pressing operations. After a
sequence of approximately 50 completed cycles you have to make a
break of 15 minutes to give the unit time to cool down.
Attention
Too intensive use can cause heat damages for the tool
Attention
During the operation of electric motors sparks can occur
which might ignite highly inflammable or explosive liquids
and materials
Attention
Electric-hydraulic pressing tools must not be operated in
pouring rain or under water.

5.3. Mounting instructions

Please reference the assembly manual of the systems supplier before
mounting the fittings on the tubes. In order to safeguard a proper
pressing and to guaranty a safe and reliable handling the machine must
only be operated with pressing jaws recommended by the provider of the
tube system and/or the tool manufacturer. If the markings on the tool and
pressing jaw do not match respectively if there are no assembly
instructions the user has to contact the provider of the system to request
a compatibility statement.
