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.

 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

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).

FORKLIFT PROTECTIONS REMOVE THE FORKLIFT PROTECTIONS BEFORE INSTALLATION

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.

Fig. 22

Page 23

INSTALLATION ON A ROOF MOUNTING FRAMES

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

Fig. 34

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)

VENTILATION BELT TENSION

BALTIC R410A-IOM-0708-E Page 58

BELT TENSION

On delivery, the drive belts are new and correctly tensioned. After the first 50 operating hours check and adjust the tension. 80% of the total elongation of belts is generally produced during the first 15 hours of operation.

Before adjusting the tension, make sure that the pulleys are correctly aligned. To tension the belt, set the height of motor support plate by moving the plate adjustment screws.

The recommended deflection is 20 mm per metre from centre to centre.

Check that according to the diagram below (figure 37), the following ratio rem ains the same.

A (mm)

= 20

P (mm)

The belts should always be replaced when:

- The disk is set to maximum,

- The belt rubber is worn or the wire is visible.

Replacement belts must have the same rated size as the ones they are replacing. If a transmission system has several belts, they must all be from the same manufacturing batch (compare serial numbers).

Fig.36

NOTE:

An under-tensioned belt will slip, heat and wear prematurely. On the other hand, if a belt is over-tensioned, the pressure on the bearings will cause them to over-heat and wear prematurely. Incorrect alignment will also cause the belts to wear prematurely.

MOUNTING AND ADJUSTING PULLEYS Fan pulley removal

Remove the 2 screws and put one of them in the extraction threaded screw.

Screw in fully. The hub and the pulley will separate from each other.

Remove the hub and the pulley by hand without damaging the machine.

Fig. 38

Fan pulley installation

Clean and de-grease the shaft, hub and conical bore of the pulley. Lubricate the screws and install the hub and pulley. Position the screws without turning them.

Place the assembly on the shaft and screw in the screws alternatively and evenly. Using a mallet or a hammer with a wooden wedge, tap on the face of the hub to keep the assembly in place. Torque the screws to 30 Nm.

Take the pulley in both hands and shake it vigorously to make sure everything is in place.

Fill the holes with grease for protection. NOTE : During installation, the key should never protrude

out of its groove. After 50 operating hours, check that the screws are still in place.

Fig.39

MOTOR PULLEY INSTALLATION AND REMOVAL

The pulley is held in position by the key and a screw located in the groove. After unlocking, removing this screw by pulling against the shaft spindle (if necessary, use a mallet and tap uniformly on the hub to remove it). To assemble, proceed in the reverse order after having cleaned and de-greased the motor shaft and the pulley bore.

PULLEYS ALIGNMENT

After adjusting one or both of the pulleys, check the transmission alignment using a ruler placed on the inner face of the two pulleys.

NOTE: The warranty may be affected if any major modification is made to the transmission without obtaining our agreement beforehand.

Fig. 40

Page 61

VENTILATION: AIRFLOW BALANCING

BALTIC R410A-IOM-0708-E Page 60

The actual resistance of ductwork systems is not always identical to the calculated theoretical values. To rectify this, it may be necessary to modify the pulley and be lt setting. To this effect, the motors are fitted with variable pulleys.

SITE TEST AND MAINTENANCE

Measure the motor absorbed power.

If the absorbed power is greater and the pressure lower than the rated values, the ventilation system has a lower pressure drop than anticipated. Reduce the flow by reducing the rpm. If the system resistance is significantly lower than design, there is a risk that the motor will overheat resulting in an emergency cut out.

If the absorbed power is lower and the pressure greater than the rated values, your system has a higher pressure drop than anticipated. Increase the flow by increasing the rpm. At the same time you will increase the absorbed power which may result in having to increase the motor size.

To carry out the adjustment and to avoid a time-consuming re-start, stop the machine and if necessary lock the main switch. First unscrew the 4 Allen screw(s) on the pulley (see figure11).

The easiest way to determine the fan rotation speed is to use a Tachometer. If not available the fan rpm can be estimated using the following two methods.

Method with the pulley secured in place:

Measure the distance between the two outside faces of the pulley. Using table (2) the motor pulley actual diameter can be estimated

method when adjusting the pulley :

-Close the pulley fully and count the number of turns from fully closed position. Using table_2 determine the motor pulley actual diameter.

-Record the fix fan pulley diameter.(DF)

-Determine the fan speed using the following formulae:

Where: rpm

:from the motor plate or table_3 DM : from table2 DF: from machine

Once the pulleys are adjusted and the belt checked and tensioned, start the fan motor and record the Amps and Voltage between the phases : Using the measured data and table_3

With the fan “rpm” and the mechanical power at the fan shaft an operating point and the supplied airflow can be estimated using the fan curves.

CHECKING AIRFLOW AND ESP

Using the fan curves on page 25, 26, 27, the airflow, the total pressure available (P

TOT

) and the corresponding dynamic pressure (Pd) can now be estimated, for a specific operating point;

The next step consists in estimating the pressure losses across the unit.

This can be achieved using the “dirty filter pressure sensor”

and the accessories pressure drop table: table_4 Also the pressure drop due to the duct inlet into the roof-top unit can be taken as 20 to 30 Pa.

EXAMPLE

The unit used for this example is a BAH035NSM1M with Economiser and Electric Heater type H It is fitted with a fan which curve is shown on page 26 and a 2.2kW motor.

- Motor rpm: 1430 rpm

- cos

 = 0.81

- Voltage = 400V

- Current = 3.77A

mech fan

= V x I x 3 x cos x 

mech motor

x 

Transmission

= 400 x 3.77 x 3 x 0.81 x 0.76 x 0.9 = 1.45kW The unit is also fitted with a transmission kit 7

- Fixed Fan pulley: 160mm

- Motor adjustable pulley type “8450” opened 4 turns from fully closed or measured distance between pulley end plates is

25.7mm: from table 2 it can be determined that the motor pulley has a diameter of 99.2mm

rpm

FAN

= rpm

MOTOR

x DM / DF = 1430 x 99.2 / 160 = 886.6 rpm

Using the fan curve below the operating point can be located. It can be determined that the fan is providing approximately 6300 m3/h with a total pressure P

TOT

= 530 Pa

The pressure losses in the unit are the sum of all pressure drops across the different parts of a unit:

- Coil and filter (measured) = 104 Pa

- Inlet into the unit = 30 Pa

- Options = 23 Pa for economiser and 91 Pa for

electric heater H

P = 104 + 30 + 23 + 91 = 248 Pa

The dynamic pressure at 7200m3/h is given at the bottom of the fan curve (page 26). Pd = 81Pa

The external static pressure available is therefore ESP = P

TOT

- Pd - P

INT

=580 - 110 - 248 = 201 Pa

FILTER REPLACEMENT

After opening the filter access panel, lift the filter retaining log. The filters can then be removed and replaced easily by sliding the dirty filters out and cle an ones in.

The CLIMATIC controller can monitor the pressure drop across the filter (If option fitted) The following set points can be adjusted depeding on the installation. “Airflow” in page 3411 = 25Pa by default

“No filter “ in page 3412 = 50Pa by default “Dirty Filter” in page 3413 = 250Pa by default

The actual pressure drop measured accross the coil can be re ad on the Climatic Display DS50 in menu 2131

The following faults may be identified

 -Fault code 0001 AIRFLOW FAILURE, if measured ΔP across the filter and coil is below the value set in page 3411  -Fault code 0004 DIRTY FILTERS, if measured ΔP across the filter and coil is above the value set in page 3413  -Fault code 0005 MISSING FILTERS, if measured ΔP across the filter and coil is below the value set in page 3412

HYDRAULIC CONNECTIONS

The hot water coil is fitted with a three way proportional valve and two isolating shut off valves. Two spanners must be used to tighten the connections. One spanner must maintain the valve body when connecting the pipe-work to the main. Failure to do so may damage the pipes joints and invalidates the warranty.

Filling up and starting the system

- Adjust the control for Heating by reducing the simulated ambient temperature down to 10°C

- Check that the red indicators located under the valve actuator are moving correctly with the signal.

- Fill the hydraulic system and bleed the coil using the

air vents. Check incoming hot water.

- Check the various connections for possible leaks

FREEZE PROTECTION

1) Glycol for freeze protection. Check the hydraulic system contains Glycol for protection

against freezing.

GLYCOL IS THE ONLY EFFECTIVE PROTECTION

AGAINST FREEZING

The antifreeze must protect the unit and avoid icing under winter conditions. WARNING: Mono-ethylene glycol based fluids may produce corrosive agents when mixed with air.

2) Drain the installation. You must ensure that the manual or automatic air bleeders

have been installed on all high points in the system. In order to drain the system, check that all the drain cocks have been installed on all low points of the system.

HEATING HOT WATER COILS FROZEN DUE TO LOW AMBIENT CONDITIONS ARE NOT COVERED BY THE

WARRANTY.

ELECTROLYTIC CORROSION

Attention is drawn to the corrosion problems resulting from electrolytic reaction created by unbalanced earth connections.

ANY COIL DAMMAGED BY ELECTROLYTIC CORROSION

IS NOT COVERED BY THE WARRANTY

GENERAL INFORMATION

The Baltic electric heaters are stand alone options which are fitted in the heating section of the unit. As for the hot water coil or the gas burner this option slides into the heating compartment located under the supply fan. In order to reduce the pressure drops the airflow is ducted around the shielded resistances. The resistances are made smooth stainless steel tubes with a capacity of 6W/cm2. It is protected as standard, against overheat via a high temperature overload protection set at 90°C and located less than 150mm after the heater itself. There are three sizes available for each size of unit:

S: Standard heat M: Medium heat

H: High heat The standard and Medium heat electric heaters are staged control with 50% or 100%. The high heat versions is controlled through a fully modulating triac.
