ming the plastic), ensuring that the whole gasket is evenly
compressed for at least 2 hours.
N.B. Some particular standards (e.g. ACS Attestation de Con-
formité Sanitaire) may prohibit direct contact between fluid
and glue. If this is the case, do not glue the parts of the ga-
sket which could come into direct contact with the fluid.
WARNING: Always follow the mandatory general standards
for personal protection, in particular: avoid contact with the
eyes, use an appropriate protective mask to protect against
inhalation hazards and wear gloves.
5.8 - Reassembly
• Before reassembling the heat exchanger, make sure that all
the plates and gaskets are clean and free of grease.
• When arranged correctly, the stacked plates form a ho-
neycomb pattern (Fig.10).
• The order of assembly and the plate direction are specified
on the plate arrangement drawing.
Procedure
• Starting from the fixed head, assemble the plates on the bar
one by one with the gaskets facing the fixed head.
• Clean and lubricate the tie-rods, position them on the fra-
me, then tighten the nuts gradually and evenly in the order

indicated in Fig.11 until the correct dimension is obtained
between the plates (tightening dimension), as specified on
the data plate. Check that this dimension is the same on
each side. Overtightening may irreversibly distort the plates.
If you feel it is necessary to tighten beyond the recommen-
ded dimension,contact CARRIER's After-Sales Department
to obtain advice.

• It is recommended to perform a pressure test after all main-
tenance on the plates and gaskets in order to check the
heat exchanger's internal and external tightness. The maxi-
mum pressure for each circuit should be equal to the ope-
rating pressure and should never exceed the rated pressure
(PS) specified on the data plate. The recommended testing
time is at least 10 minutes. Nevertheless, it remains the
user's responsibility to check national standards and local
codes affecting such a test. If different test conditions are
