LAZERWELD II PLATE HEAT EXCHANGER
MAINTENANCE
NOTICE
Make sure the two gasket prongs of the Clip-on tabs
are in the correct position.
6. Repeat the procedure until all cassettes that are
needed to be regasketed are done. Close the LZWII
(see
Closing ).
Adhesive tape
The procedures below apply to end cassette gasket sup-
ports and distance rings fastening by means of adhesive
tape around the ports and along the sides.
Adhesive tape (GC1) is a simple and secure way to position
gasket. Affix the gasket to the groove using a special tape
gun which enables you to apply the tape exactly where
required.
1. Open the LZWII (see Opening) and remove the cassette
to be regasketed.
NOTICE
Before opening the LZWII check warranty terms and
conditions. If in doubt, contact your FRICK sales rep-
resentative. See
Warranty conditions .
2. Remove the old gasket.
3. You do not need to remove any old tape because the
film is very thin. Ensure that the gasket groove is clean
and dry however.
4. Apply tape using the tape gun.
5. Attach the gasket to the cassette. The gasket place-
ment of the respective cassette type can be advised by
your FRICK representative.
6. Close the heat exchanger, (see Closing ).
Glued gaskets
Use glue recommended by FRICK. Separate gluing instruc-
tions are delivered together with the glue.
Note: Glued gaskets are not allowed in refrigerant side of
the heat exchanger.
CAUTION
Other glues than those recommended can contain
chlorides that can damage the plates.
CAUTION
Do not use sharp tools when removing the glued
gasket to avoid damage to the plates.
CLOSING
Follow the instructions below to ensure that the LZWII is
properly closed.
1. Check that all the sealing surfaces are clean.
2. Brush the threads of the bolts clean using a steel wire
brush or thread cleaner. Lubricate the threads with a
thin layer of grease, such as Gleitmo 800 Lubriplate or
equivalent.
3. Attach gaskets to the cassettes or check that all the
gaskets are properly attached.
NOTICE
If the gasket is wrongly positioned, it can rise out
of the gasket groove or be positioned outside the
groove.
4. Insert the cassettes in alternate directions and with
the gaskets turned towards the frame plate or pres-
sure plate as specified on the plate hanging list. Use
the marked line that was done when the LZWII was
opened. See step 3 in the
Opening section.
