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
in stalled on the circuit (screen filter, pump, water flow switch,
etc.).
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
• Inspect the unit for damage or missing parts. If damage is
detected, or if shipment is incomplete, immediately file a
claim with 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
- 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 the options ordered for on-site installation have
been supplied, are complete and undamaged.
• Do not keep the BW10 units outside where they are exposed
to the weather, as the sensitive control mechanism and the
electronic modules may be damaged.
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, the damaged parts
must be repaired or replaced. See chapter “Maintenance”.
The machine must be installed in a place that is not
accessible to the public or protected against access by non-
authorised persons.
2.2 - Moving and siting the unit
2.2.1 - Moving
See chapter 1.1 - “Installation safety considerations”.
2.2.2 - Siting the unit
Always refer to the chapter “Dimensions and clearances” to
confirm that there is adequate space for all connections and
service operations. For the centre of gravity coordinates, the
position of the unit mounting holes, and the weight
distribution points, refer to the certified dimensional drawing
supplied with the unit.
Typical applications of these units are in refrigeration
systems, and they do not require earthquake resistance.
Earthquake resistance has not been verified.
In case of extra-high units the machine environment must
permit easy access for maintenance operations.
CAUTION: Only use slings at the designated lifting points
which are marked on the unit.
Before siting the unit check that:
• the permitted loading at the site is adequate or that
appropriate strenghtening measures have been taken.
• the unit is installed level on an even surface (maximum
tolerance is 1.5 mm in both axes).
• there is adequate space above the unit for air flow and to
ensure access to the components.
• the number of support points is adequate and that they are
in the right places.
• the location is not subject to flooding.
• No material or object that can be affected by condensate
(even a small amount) must be left under the machine or
in the water flow direction.
CAUTION: Before lifting the unit, check that all casing
panels are securely fixed in place. Lift and set down the unit
with great care. Tilting and jarring can damage the unit and
impair unit operation.
ATTENTION: Stacked units must not be moved.
If BW10 units are hoisted with rigging, it is neces-sary to
protect the unit frame (side and rear panels and front doors)
against accidental crushing. Use struts or lifting beams to
spread the slings above the unit. Do not tilt a unit more than
15°, or 5° for units with the stacking option (No. 273). Always
follow the instructions on the handling notice attached to the
unit.
If a unit includes a hydronic module (options 116 or 270), the
hydronic module and pump piping must be installed in a way
that does not submit it to any strain. The hydronic module
pipes must be fitted so that the pump does not support the
weight of the pipes.
Never push or lever on any of the enclosure panels (panels,
uprights, front access doors) of the unit. Only the base of the
unit frame is designed to withstand such stresses.
