All Baltic Units are compliant with the PED directive 97-23/CE The following note must be followed carefully
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 unbraz ing 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.
The brazing shall be carried out by a qualified brazier. The brazing shall comply with standard NF EN1044 (minimum 30%
silver).
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.

TRANSPORT - HANDLING
BALTIC R410A-IOM-0708-E Page 11
DELIVERY CHECKS
On receipt of a new equipment please check the following
points. It is the customer’s responsibility to ensure that the
products are in good working order:
- The exterior has not been damaged in any way.
- The lifting and handling equipment are suitable for the equipment and comply with the specifications of the handling instructions enclosed here-in.
- Accessories ordered for on site installation have been delivered and are in good working order.
- The equipment supplied corresponds to the order and matches the delivery note.
If the product is damaged, exact details must be confirmed in writing by registered post to the shipping company within 48 hours of delivery (working days). A copy of the letter must be addressed to Lennox and the supplier or distributor for information purposes. Failure to comply will invalidate any claim against the shipping company.
RATING PLATE
The rating plate provides a complete reference for the model and ensures that the unit corresponds t o the model ordered. It states the electrical power consumption of the unit on start-up, its rated power and its supply voltage. The supply voltage must not deviate beyond +10/-15 %. The start-up power is the maximum value likely to be achieved for the specified operational voltage. The customer must have a suitable electrical supply. It is therefore important to check whether the supply voltage stated on the unit's rating plate is compatible with that of the mains electrical supply. The rating plate also states the year of manufacture as well as the type of refrigerant used and the required charge for each compressor circuit.
Fig. 1
STORAGE When units are delivered on site they are not always
required immediately and are sometimes put into storage. In the event of medium to long-term storage, we recommend the following procedures:
- Ensure that there is no water in the hydraulic systems.
- Keep the heat ex changer covers in position (A QUILUX cove r).
- Keep protective pl astic film in position.
- Ensure the electrical panels are closed.
- Keep all items and options supplied in a dry and clean place for future assembly before using the equipment.
MAINTENANCE KEY
On delivery we recommend that you keep the key which is attached to an eyebolt in a safe and accessible place. This allows you to open the panels for maintenance and installation work. The locks are ¼ turn + then tighter (figure 2).
CONDENSATE DRAINS
The condensate drains are not assembled when delivered and are stored in the electrical panel with their clamping collars. To assemble them, insert them on the condensate tray outlets and use a screwdriver to tighten the collars (Figure 3).

PRELIMINARY CHECKS
Before installing the equipment, the following points MUST be checked:
- Have the forklift protections been removed?
- Is there sufficient space for the equipment?
- Is the surface on which the equipment is to be installed sufficiently solid to withstand its weight? A detailed study of the frame must be made beforehand.
- Do the supply and return ductwork openings excessively weaken the structure?
- Are there any obstructing items which could hinder the operation of the equipment?
- Does the electrical power available correspond to the equipment's electrical specifications?
- Is drainage provided for the condensate?
- Is there sufficient access for maintenance?
- Installation of the equipment could require different lifting methods which may vary with each installation (helicopter or crane). Have these been evaluated?
- Ensure that the unit is installed in accordance with the installation instructions and local applicable codes.
- Check to ensure that the refrigerant lines do not rub against the cabinet or against other refrigerant lines.
In general, make sure no obstacles (walls, trees or roof ledges) are obstructing the duct connections or hindering assembly and maintenance access.
INSTALLAT ION REQUIREMENTS
The surface on which the equipment is to be installed must be clean and free of any obstacles which could hinder the flow of air to the condensers:
-Avoid uneven surfaces
-Avoid installing two units side by side or close to each other as this may restrict the airflow to the condensers.
Before installing a packaged Rooftop unit it is important to understand:
- The direction of prevailing winds
-The direction and position of air flows.
-The external dimensions of the unit and the
dimensions
of the supply and return air connections.
-The arrangement of the doors and the space required to open them to access the various components.
CONNECTIONS
-Ensure that all the pipe-work crossing walls or roofs are secured, sealed and insulate d.
-To avoid condensation problems, make sure that all pipes are insulated according to the temperatures of fluids and type of rooms.
NOTE: The AQUILUX protection sheets fitted to the finned surfaces must be removed prior to start up.

POSITIONING ROOFCURBS
As levels are adjustable, observe the following recommendations when installing the equipment.
Above all, ensure that all the adjustable returns are facing outward (“1” figure 17). They are usually turned inside-out for transport.
Place the roof mounting frame on the trimmer beam by first lining up the inlet and the outlet opening. (“2”- figure 18)
After levelling the frame, secure the adjustable returns on the trimmer.
It is important to centre the unit on the roof frame.

FRAME PARTS IDENTIFICATION Figure 20 shows the different parts used in the assembly of this roof mounting frame.
INSTALLATION
The roof mounting frame provides support when the units are installed in down-flow configurations. The non adjustable, non assembled roof mounting frame can be installed directly on decks having adequate structural strength or on roof supports under deck. See page 24 for frame dimensions, location of supply and return air opening
NOTE: frame assembly must be installed flat, levelled within 5mm per linear meter in any direction.

ASSEMBLY
The frame is supplied as a single package and shipped folded down for ease of transport and handling. It is easy field assembled as all parts required are supplied with the frame.
SECURING THE FRAME
To ensure proper mating with units (figure 22), it is mandatory that the roof mounting frame be squared to roof structure as follows:
-With frame positioned levelled in the desired location on roof trusses, tack weld corne r of frame.
-Measure frame diagonally from corner to corner as shown in figure 16. These Dimensions must be equal in order for the fame to be square.
-It is extremely important to sight frame from all corner to ensure it is not twisted across. Shim frame under any low side. The maximum slope tolerance is 5mm per linear meter in any direction.
-After the frame has been squared, straightened and shimmed, weld or secure the frame to the roof deck.
NOTE: It must be securely fastened to the roof as per local codes and regulations.

BALTIC R410A-IOM-0708-E Page 22
SECURING THE CURB
When the frame is correctly positioned, it is essential to secure the assembly with a disconnected stitched welded seam (20 to 30 mm every 200 mm
- - - -) along the outside or by using an alternative method.
CURBING AND FLASHING
Outside of frame must be insulated with rigid type insulation; We recommend a minimum of 20 mm thick insulation (2 figure 24).
Check that the insulation is continuous, counter flash and seal around the frame as shown in (1-figure 24).
CAUTION: To be effective, the upstream must end below the drop edge (3 - figure
24). Where pipes and electrical conduits extend through the roof, flashing must
conform to local codes of practice
Before installing the equipment, make sure that seals are not damaged and check that the unit is secured to the mounting frame. Once in position, the bottom of the equipment must be horizontal. The installer must comply with local authority standards and specifications.

ECONOMISER AND EXTRACTION
BALTIC R410A-IOM-0708-E Page 24
Economiser
Free cooling can be provided through the use of fresh air where appropriate rather than cooling excessive amounts of return air. The economiser is factory fitted and tested prior to shipment. It includes two dampers operating from a 24V actuator
Rain hood
It also includes a factory fitted rai n hood. Hoods is folded during transportation to limit risks of damage and must be unfolded on site as shown on fig. 26
Extraction
Installed with economiser assembly, the gravity exhaust dampers relieve the pressure when outside air is introduced into the system. When large amount of fresh air is introduced into the system power exhaust fans can be used to equalise the pressures. The extraction fan runs when return air dampers are being closed and supply air blower is in operation. The extraction fan runs when outdoor air dampers are at least 50% open (adjustable value). It is overload protected. NOTE: When horizontal flow configuration is required, the multidirectional roof curb will be installed.

ELECTRICAL CONNECTIONS
Ensure that the power supply between the building and the
unit meets local authority standards and that the cable specification satisfies the start-up and operating conditions.
ENSURE THAT THE POWER SUPPLY
INCLUDES 3 PHASES
(+ NEUTRAL if the unit is equipped with the
power exhaust fan)
Check the following wire connections for tightness:
Main switch connections, mains wires linked to the contactors and circuit breakers and the cables in the 24V control supply circuit.
How to connect roof curbs and energy recovery module
Cables and their connectors corresponding to the roof curb motor and actuator and extraction box ones are already rolled up in these elements; it is enough to bring them through the openings envisaged and to connect them on the sites indicated on the figure 28.
It’s the same procedure when you have an energy recovery module.
PRELIMINARY CHECKS
Ensure that all drive motors are secure. Ensure that the adjustable pulley blocks are secure and
that the belt is tensioned with the transmission correctly aligned. Refer to the next section foe details.
Using the electrical wiring diagram, check the
conformity of the electrical safety devices (circuit breaker settings, presence and rating of fuses).
Check the temperature probe connections.

POWERING THE UNIT
- Power up the unit by closing the isolator switch (if fitted).
- At this point the blower should start unless the climatic does not energise the contactor. In this particular case the blower can be forced by bridging the port NO7 and C7 on connector J14 on the Climatic. Once the fan is running, check the rotation direction. Refer to the rotation arrow located on the fan.
- The fans and compressors direction of rotation is checked during the end of line test. They should therefore all turn in either the right or wrong direction.
NOTE: A compressor rotating in the wrong direction will fail.
- If the fan turns in the wrong direction (the right direction is shown on figure n° 27), disconnect the main power supply to the machine at the building's mains switch, reverse two phases and repeat the above procedure.
- Close all circuit breakers and power up the unit, remove the bridge on connector J14 if fitted.
- If now only one of the components rotates in the wrong direction, disconnect the power supply at the machine's isolator switch (if fitted) and reverse two of the
component’s phases on the terminal within the electrical
panel.
- Check the current drawn against the rated values, in particular on the supply fan (ref. page 34).
- If the readings on the fan are outside the specified limits, this usually indicates excessive air flow which will affect the life expectancy and the thermodynamic performances of the unit. This will also increase the risks of water ingress into the unit. Refer to the "Air Flow Balancing" section to correct the problem.
At this point attach the manometers to the refrigerant circuit

RUN TEST
Start unit in cooling mode
Thermodynamic readings using manometers and prevailing environmental conditions No rated values are given here. These depend on the climatic conditions both outside and inside the building during operation. However, an experienced refrigeration engineer will be able to detect any abnormal machine operation.
Safety test
- Check Air pressure switch (if fitted) "Dirty filter" detection test: vary the set-point value (menu page 3413 on DS50) in respect to the air pressure value. Observe the response of the CLIMATIC™.
- Same procedure for detecting "Missing Filter" (page menu 3412) or "Air Flow Detection" (page menu 3411).
- Check the smoke detection function (if fitted).
- Check the Firestart by press ing the test button (if fitted).
- Disconnect the circuit breakers of the capacitor fans and check the high pressure cut-out points on different refrigerant circuits.
Reverse cycle test
This test is designed to check the good operation of the 4­way reversing valves on heat pump reversible systems. Start the reverse cycle by adjusting the cold or hot temperature threshold data according to the i ndoor and outdoor conditions at the time of te st (menu 3320)
