2. Deburr carefully the end of the tube on the inside to
minimize turbulence and pressure loss according to the
relevant plumbing code and on the outside to avoid
damaging the O-ring.
The following is a step by step guide to installing the KemPress®System. For projects requiring maintenance and repair, visually
inspect the copper tube to ensure it is in reasonable condition with no signs of external corrosion.
3. For existing copper tube, clean the end with emery
paper or a soft scourer. 4. Mark the insertion depth by lining up the fitting side by
side with the tube and mark the tube. When the fitting is
inserted onto the tube the outer edge of the fitting must
line up with the marking. For correct insertion depths see
the table below.
1. Cut copper tube to length using a pipe cutter.
5. Select pressing jaw according to the fitting dimension and
insert into the pressing machine. Arrest the locking bolts of
the machine. Check the jaws are free from debris and in
good working order.

7. Check the fitting outer edge still lines up with the marking.
Open the pressing jaw and close it around the fitting so
the raised bump in the fitting rests inside the groove of the
pressing jaw.
8. Initiate the pressing job by pressing the start button. The
automatic pressing process guarantees a tight connection.
6. Check the fitting is clean and the O-ring is free from debris
and correctly sitting in place. Push fitting on tube all the
way to the engagement marking.
9. Visually inspect the fitting to ensure the press has been
completed. The KemPress®tool will flash if the fitting did
not press correctly. If this occurs a new fitting and tube
section is required. At the end of the project visually inspect
each fitting to ensure none have been missed.

CAUTION
Brazing or soldering near to KemPress
®
joints should be avoided
as this may cause the seal to degrade due to heat transfer.
The table below states the minimum distance away from the
press joint which is acceptable to braze. If this distance cannot
be maintained then adequate precautions must be taken such
as fabricating the brazed section prior to assembly with the press
fittings, wrapping the press joint in a wet rag and keeping cool
during brazing or applying tube freezing spray.

Key Features
• Safe handling with slip-proof rubberised housing
• Signals if press not completed correctly - Immediately
after the pressing cycle a green lights shows if the required
pressing force was achieved, a red light if not
• Automatic press cycle. Once it starts, it will automatically
complete. (manual override)
• Electronic log book allows for quick and precise
analysis of errors for servicing and repair
• Electronic monitoring of the jaw locking
bolt and visual error indicator (KPL)

before a service is required a warning light flashes.
The machine will not close down enabling you to
complete the job in hand.
• Redundant switch-off

Tool Operation
Holding the tool securely, press and hold the start button for
2 seconds to begin the automatic press cycle (the green LED
will go out). Release the start button and continue to hold the
tool securely. The green LED will light when the press cycle is
complete. To cancel the automatic press cycle press and hold
the release button on the side of the tool until the tool turns off.
If the red LED lights up, press the start button. If the tool does
not run, call Kembla Hong Kong for advice. If the red and
green LEDs flash alternately, the tool is ready for a service,
contact Kembla Hong Kong Customer Service Centre.
The tool will turn off automatically after 30 minutes of no use.
Turn the tool ON by quickly pressing and releasing the start
button and open the jaws around the fitting.
Tool Maintenance
Carry out basic inspection of the pressing device and jaws prior
to each use to ensure they are clean and free from debris and
dirt. The pressing jaws should be visually inspected to ensure
there are no cracks. If there are any cracks in the pressing jaws,
do not use them, as there is risk of the jaws shattering and
potential injury from flying fragments. It is recommended to
always wear appropriate eye protection whenever using the
pressing device. When inspecting the pressing jaws, also ensure
that there are no foreign material deposits and that the contours
of the jaw surfaces are in order. Failure to do this may result in
damage to the jaws and/or the pressing device. Always remove the
battery before performing regular cleaning and maintenance work.
The pressing device, jaws and batteries must be serviced at
least within 40,000 presses. Failure to have the required services
carried out may affect the warranty.
