General information and hydraulic module
Unit installation
Read this manual thoroughly before starting machine installation.
The device complies with the low voltage directives, Machinery
Directive and EMC Directive.
• The installation must be carried out by a qualifi ed installer.
• Follow all current national safety code requirements. In particular ensure
that a properly sized and connected ground wire is in place.
• Check that voltage and frequency of the mains power supply are those
required; the available power must be adequate to operate any other
possible appliances connected to the same line. Also ensure that national
safety code requirements have been followed for the mains supply circuit.
• After installation thoroughly test the system operation and explain all
system functions to the owner.
• Leave this manual with the owner for consultation during future periodic
maintenance.
• Be sure the unit and its components are checked periodically to look for
loosen, damaged or broken components. In case of persisting defects,
the unit may cause personal injury or property damage.
IMPORTANT
:
During the unit installation make fi rst the hydraulic connections
and then electrical connections. If unit is uninstalled fi rst disconnect
electrical cables, then the hydraulic connections.
CAUTION
:
Disconnect the mains power supply switch before servicing the
system or handling any internal parts of the unit.
• The manufacturer declines any liability for damage resulting from
modifi cations or errors in the electrical or hydraulic connections.
• Failure to observe the installation instructions or use of the unit under
conditions other than those indicated in Tables "Operating limits", will
immediately void the unit warranty.
• Failure to observe electric safety codes may cause a fi re hazard in case
of short circuits.
• Do not install or use damaged units.
• During unit operation, some of the refrigerant circuit elements could
reach a temperature in excess of 70
personnel should access areas protected by access panels.
• In case of any malfunctioning turn the unit off , disconnect the mains
power supply and contact a qualifi ed service engineer.
• All of the manufacturing and packaging materials used for your new
appliance are compatible with the environment and can be recycled.
• Dispose of the packaging material in accordance with local requirements.
• This equipment contains refrigerant R-410A that must be disposed of
in a proper manner. When disposing of the unit after its operational life,
remove it carefully. The unit must then be delivered to an appropriate
disposal center or to the original equipment dealer.
• Carefully recover refrigerant within this unit before fi nal disposal or when
servicing. Never vent refrigerant to atmosphere.
Choosing the installation site
• This unit should not be installed in an explosive atmosphere.
• The unit can operate in normal radioelectric atmospheres in residential,
commercial and light industrial installations. For other applications,
please consult Carrier.
• In the case of heat pump operation with an outdoor temperature of
less than 0 °C the unit must be installed at least 300 mm above ground
level. This is necessary to prevent ice from accumulating on the frame
and to permit correct operation also in the event of heavy snowfalls.
The unit must be levelled on both axes (the tolerance is less than 2 mm
per metre).
• In some cases it may be necessary to fi t defl ectors against strong winds
and to stop snow from hitting the coil directly. These defl ectors must be
installed so that the normal air circulation is not obstructed.

CAUTION:
Typical applications of these units are in refrigeration systems, and
they do not require earthquake resistance.
Earthquake resistance has not been verifi ed.
Installation instructions for ductable units
Units 30RBY (ductable unit ) can be installed in buildings and connected
by means of duct systems
- on the outside air inlet side (only units size 17-21 kW)
- on the fan side where the air is released after passing through the air/
refrigerant exchanger.
Therefore the unit can be installed in a building without changing the
indoor air temperature.
These units are designed for a static pressure of 80 Pa: for this reason,
the friction loss of any intake duct added up to the friction loss of the
supply duct must not exceed the indicated value. For units size 17-21
kW: if the units are not provided with a supply duct, a protective grille
must be installed to prevent access to fans.
Unit with optional intake fi lters (size 17 -21 kW).
Access to fi lters for maintenance of units 17 and 21 kW is possible by
removing the screws on the fi lter support side.
After removing the screws remove the closing panel.
Remove the fi lters on the unit back side as shown below.
The friction loss of the fi lters with nominal air fl ow is 7 Pa.
Check the fi lter is clean every two or three months (more often if the
unit is installed in a dusty place) and when the friction loss is twice the
nominal value.
A dirty fi lter causes a decrease in air fl ow and in the unit effi ciency.
The fi lter should be cleaned with air (not water) as it is made of aluminium.
