General information and hydronic 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 qualified 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 first the hydronic connections and
then electrical connections. If unit is uninstalled first disconnect
electrical cables, then the hydronic 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
modifications or errors in the electrical or hydronic 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 fire 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 qualified 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 final 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 fit deflectors against strong
winds and to stop snow from hitting the coil directly. These deflectors
must be installed so that the normal air circulation is not obstructed.
GB - 10

CAUTION:
Typical applications of these units are in refrigeration
systems, and they do not require earthquake resistance.
Earthquake resistance has not been verified.
Installation instructions for ductable units
Units 30RBY and 30RQY (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 filters (size 17 -21 kW).
Access to filters for maintenance of units 17 and 21 kW is possible by
removing the screws on the filter support side.
After removing the screws remove the closing panel.
Remove the filters on the unit back side as shown below.
The friction loss of the filters with nominal air flow is 7 Pa.
Check the filter 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 filter causes a decrease in air flow and in the unit efficiency.
The filter should be cleaned with air (not water) as it is made of
aluminium.
