Attachment of drain elbow
• In case of using the drain elbow, attach it as illustrated.
• Do not attach the drain elbow in cold districts where the air
temperature falls below zero continuously.
Frozen drain may cause to stop the fan motor.
9.6 ELECTRICAL CONNECTIONS
All electrical connections made on site are solely the responsibility
of the installer.
DANGER
Electrical shock may cause serious
personal injury or death. Electrical connections must only be per-
formed by qualified personnel.
DANGER
• All cables and hydraulic components must be installed by a licensed
technician and comply with all relevant European and national
standards.
• Ensure the power supply system complies with the national safety
standards in force.
• The electrical wiring must be carried out according to the wiring diagram
supplied with the unit, and the instructions provided below.
• Turn off the power supply before making any connections.
• Ensure an effective grounding line is available.
• Be sure to use a dedicated electrical power supply system. Never use a
power supply shared by another appliance.
• Check that the voltage and frequency of the electric system are those
required.
Section II :: Installation and maintenance
Hose
Drain elbow
• Ensure the impedance of the power supply line conforms to the electrical
absorption of the unit specified on its data plate.
• It is necessary to incorporate a main switch in the fixed wiring or other
means for disconnection having a contact separation in all poles, in
accordance with relevant local and national legislation.
• Emergency disconnect devices from the mains must allow for
disconnection in accordance with the conditions of
overvoltage protection class III.
• Make sure to install a protective earth leakage device (30 mA). Failure to
observe this warning may cause electric shock.
• Make sure to establish a grounding line. Do not ground the unit by
connecting it to a service pipe, a voltage absorber or a phone line
grounding block. Incomplete grounding may cause electric shock.
• Do not change the unit by removing safety devices or by-passing safety
switches.
ATTENTION
• Properly connect the connecting cable to prevent damage to electrical
components.
• Connection to the mains is of Y type, thus replacing the cable should only
be done by the technical service in order to prevent risks.
• For wiring, use specific cables and firmly connect
them to terminals.
• The service current flow must be 10 A for each phase.
Basically, the service current flow is the main fuse rating, or the setting
of the overcurrent protection, of the circuit breaker, at the interface point
between the public supply network and the user installation.
