INSTALLATION MANUAL
• The brazing shall be carried out by a qualifi ed brazier. The brazing shall comply with standard NF EN1044 (minimum 30% silver).
EMC DIRECTIVE COMPLIANCE
WARNING:
This equipment is an "A class" according CEM Directive. In an industrial environment, this device can create radio electrical noise. In
this case, the owner can be asked to take appropriated actions.
This applies to all machine installed with nominal amps below <75A:
• The short-circuit rate Rsce=33 is defi ned in the EN61000-3-12 standard relative to the harmonics readings on the supply network.
The appliances compliant with the harmonic current limits equivalent to Rsce=33 can be connected in whatever connection point
of the main supply system.
• The maximal allowable impedance of the main supply system Zmax=0.051W is defi ned by EN 61000-3-11 standard relative to
the voltage variation, fl uctuation and fl icker readings. The connection to the supply is a conditional connection submitted to the
preliminary agreement of the power supply local provider.
Replacing components:
• In order to maintain CE marking compliance, replacement of components shall be carried out using spare parts, or using parts
approved by LENNOX.
• Only the coolant shown on the manufacturer's nameplate shall be used, to the exclusion of all other products (mix of coolants,
hydrocarbons, etc.).
CAUTION:
In the event of fi re, refrigerating circuits can cause an explosion and spray coolant gas and oil.
Transport – Handling- Access:
• Never lift the unit without forklift protections
• An approach ramp must be installed if the unit's installation requirements tell that it's necessary to reach the main switch, the electrical
cabinet, the compressor and the ventilation compartment. This recommendation is valid for all type of installations.
• It is strictly forbidden to walk or store equipment or material on top of the rooftop unit
Rooftop installation in heavy wind locations
• The roofcurbs (vertical & horizontal) and rooftops installations are designed to withstand winds up to 80 km/h. Above this limit, it's
recommended to take appropriate actions to secure the installation.
• Ensure the fresh air inlet does not face prevailing wind direction.
Elbow or section changes in ductworks next to the rooftop
• Whatever the supply confi guration is, respect a minimal duct's length of 2 m before any elbow or any duct's section change.
• Directional vanes must be fi tted inside any elbow fi tted in return or supply ductwork closer than 5 meter to the machine connection
fl anges.
Filters:
• Do the fi lters fi re classifi cation's choice according to local regulations.
Fan compartment:
• Stop the power before accessing the fan compartment.
Gas:
• Any work on gas module must be carried out by qualifi ed personnel
• A unit with gas module must be installed in accordance with local safety codes and regulations and can only be used for outdoor
installation.
