Hydraulic Connections - Carrier 10TE Serie Installations-, Betriebs- Und Wartungsanweisungen

• If the heat exchanger is to be installed on framework, the
structure must be designed to withstand the weight of the
exchanger when in operation (filled) and with its accessories.
• If necessary, affix the hazard symbol corresponding to the
Product picture - black and white
fluid in accordance with applicable standards.

• Take all appropriate steps to mitigate the effects of any signifi-
cant human, environmental or financial consequences of failure.
• Make sure that the heat exchanger is always installed verti-
cally, stable, and secured using all its anchorage points. If
necessary, fit additional anchors suitable for the foreseeable
stresses.
• Install drains and vents, shut-off valves, and fill and drain
valves on the pipes so that the heat exchanger can be serv-
iced without disrupting the system.
• In the event of seasonal use, drain the heat exchanger com-
pletely to prevent any risk of freezing or corrosion if a cor-
rosive fluid is used.
• If accessories are installed on the heat exchanger, refer to
their specific instructions.

3.3 - Hydraulic connections

• To keep the insides of the pipes clean, do not remove the
seals on their ends until you are ready to make the hydraulic
connections.
• The insides of the pipes must be free of all foreign matter
(sand, welding slag, other solid matter, etc.) that could dam-
age the plates and gaskets.
• Filtration: If the fluids to be circulated through the heat ex-
changer contain suspended matter, a filtration system of up

to 500 µm must be installed.
• Check the tightening dimension specified on the data plate.
Refer to section 5.7 if retightening is needed.
• Make the hydraulic connections as instructed on the label
on the frame or on the plate arrangement drawing.
• Never insert foreign matter into the circuit.
• No strain should be placed on the pipes (weight of connect-
ed pipes, expansion, vibrations etc.).
• If threaded couplings are used,
do not apply the tightening torque
to the threaded nozzles.
• Threaded nozzles are not weld-
ed to the fixed head. To avoid
damaging the first gasket, hold
the threaded nozzles in place
with pliers and screw on the
pipes (Fig. 4).
• If the ports on the fixed head
are fitted with protective built-in
linings, the linings must be suffi-
ciently compressed so that the head and the counter-flange
are separated by a 2 mm gap (tightening any further will
damage the linings).
• In the case of a multi-pass heat exchanger (fluid inlet and
outlet ports on both ends): install an expansion fitting or a
horseshoe loop and use detachable pipes so that more plates
can be added and the movable follower can be removed.
