The refrigerant lines can break under the weight and release
refrigerant, causing personal injury.
Do not climb on a machine. Use a platform, or staging to
work at higher levels.
Use mechanical lifting equipment (crane, hoist, winch, etc.)
to lift or move heavy components. For lighter components,
use lifting equipment when there is a risk of slipping or
losing your balance.
Use only original replacement parts for any repair or
component replacement. Consult the list of replacement
parts that corresponds to the specification of the original
equipment.
Do not drain water circuits containing industrial brines,
without informing the technical service department at the
installation site or a competent body first.
Close the entering and leaving water shutoff valves and
purge the unit water circuit, before working on the compo-
nents installed on the circuit (screen filter, pump, water
flow switch, etc.).
Do not loosen the water box bolts until the water boxes
have been completely drained.
Periodically inspect all valves, fittings and pipes of the
refrigerant and hydronic circuits to ensure that they do
not show any corrosion or any signs of leaks.
It is recommended to wear ear defenders, when working
near the unit and the unit is in operation.
2 - PRELIMINARY CHECKS
2.1 - Check equipment received
•
Check that the unit has not been damaged during
transport and that no parts are missing. If the unit has
been damaged or the shipment is incomplete, send a
claim to the shipping company.
•
Compare the name plate data with the order. The name
plate is attached in two places to the unit:
-
On one of the unit sides on the outside,
-
On the control box door on the inside.
•
The unit name plate must include the following
information:
-
Version number
-
Model number
-
CE marking
-
Serial number
-
Year of manufacture and test date
-
Fluid being transported
-
Refrigerant used and refrigerant class
-
Refrigerant charge per circuit
-
Containment fluid to be used
-
PS: Min./max. allowable pressure (high and low
pressure side)
-
TS: Min./max. allowable temperature (high and
low pressure side)
-
Pressure switch cut-out pressure
-
Unit leak test pressure

-
Voltage, frequency, number of phases
-
Maximum current drawn
-
Maximum power input
-
Unit net weight
•
Confirm that all accessories ordered for on-site installa-
tion have been supplied, are complete and undamaged.
The unit must be checked periodically during its whole
operating life to ensure that no shocks (handling accessories,
tools etc.) have damaged it. If necessary, damaged parts must
be repaired or replaced. See also chapter 13 - "Standard
maintenance".
2.2 - Moving and siting the unit
2.2.1 - Moving
See chapter 1.1 "Installation safety considerations".
In some cases vertical supports are added for the transport
and handling of the unit. These supports can be removed
for access or connection, if required.
IMPORTANT: Follow the disassembly sequence shown
in the disassembly instruction notes.
•
Unscrew screws marked 1 and 2.
•
Loosen screw 3, and lift and remove support 4.
•
Uncrew screw 5 and loosen screw 6.
•
Lift and remove support 7.
•
Unscrew screw 8 and remove plate 9.
Keep the vertical supports after commissioning the units
and re-insert them when the unit is moved.
