INSTALLATION MANUAL

Safety codes & regulations

THE UNIT MUST BE INSTALLED IN ACCORDANCE WITH LOCAL SAFETY CODES AND REGULATIONS AND CAN ONLY BE

USED IN WELL VENTILLATED AREA.

PLEASE READ CAREFULLY THE MANUFACTURER’S INSTRUCTIONS BEFORE STARTING THIS UNIT.

INSPECTIONS AND REQUALIFICATION ACCORDING PRESSURE EQUIPMENT DIRECTIVE MUST FOLLOW THE LOCAL

REGULATIONS WHERE THE UNIT IS INSTALLED.

Important note for unit ﬁtted with gas burner:

The following note must be followed carefully

THIS MANUAL IS ONLY VALID FOR UNITS DISPLAYING THE FOLLOWING CODES:

GB IR GR DA NO FI IS

In case these symbols are not displayed on the unit, please refer to the technical documentation which will eventually detail any

modiﬁcations required to the installation of the unit in a particular country.

• If machine is including gas burner, minimum clearance around the unit must be at least 8 m to allow a proper gas ﬂue dilution. If

not possible, the fresh air intake must be ducted at least 8 m away from the gas burner exhaust.

• The gas burner air intake and exhaust chimney must not be modiﬁed or ducted.

• Before commissioning this type of unit, it’s mandatory to ensure that the gas distribution system is compatible with the adjustments

and settings of the unit.

• Gas module can only be used for outdoor installations.

• Any work on gas module must be carried out by qualiﬁed engineer.

All units are compliant with the PED directive 97-23/CE

All the technical and technological information contained in this manual, including any drawing and technical descriptions provided

by us, remain the property of LENNOX and must not be utilised (except in operation of this product),reproduced, issued to or made

available to third parties without the prior written agreement of LENNOX. The technical information and speciﬁcations contained in

this manual are for reference only. The manufacturer reserves the right to modify these without warning and without obligation to

modify equipment already sold.

All work on the unit must be carried out by a qualiﬁed and authorised employee.

Non-compliance with the following instructions may result in injury or serious accidents.

Work on the unit:

• The unit shall be isolated from the electrical supply by disconnection and locking using the main isolating switch.

• Workers shall wear the appropriate personal protective equipment (helmet, gloves, glasses, etc.).

Work on the electrical system:

• Work on electric components shall be performed with the power off (see below) by employees having valid electrical qualiﬁcation

and authorisation.

Work on the refrigerating circuit(s):

• Monitoring of the pressures, draining and ﬁlling of the system under pressure shall be carried out using connections provided for

this purpose and suitable equipment.

• To prevent the risk of explosion due to spraying of coolant and oil, the relevant circuit shall be drained and at zero pressure before

any disassembly or unbrazing of the refrigerating parts takes place.

• There is a residual risk of pressure build-up by degassing the oil or by heating the exchangers after the circuit has been drained.

Zero pressure shall be maintained by venting the drain connection to the atmosphere on the low pressure side.

• 4 • BALTIC-IOM-0412-E / Installation manual

INSTALLATION MANUAL

• The brazing shall be carried out by a qualiﬁed 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 deﬁned 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 deﬁned by EN 61000-3-11 standard relative to

the voltage variation, ﬂuctuation and ﬂicker 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 ﬁre, 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 conﬁguration is, respect a minimal duct’s length of 2 m before any elbow or any duct’s section change.

• Directional vanes must be ﬁtted inside any elbow ﬁtted in return or supply ductwork closer than 5 meter to the machine connection

ﬂanges.

Filters:

• Do the ﬁlters ﬁre classiﬁcation’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 qualiﬁed 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.

The technical information and speciﬁcations contained in this manual are for reference only. The manufacturer reserves the right to

modify these without warning and without obligation to modify equipment already sold.
