TRANSPORT - HANDLING

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 to the model ordered. It states the electrical power consumption of the unit on startup, 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.

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 exchanger covers in position (AQUILUX cover).

- Keep protective plastic 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 1).

Fig. 1

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 2).

FORKLIFT PROTECTIONS

NEVER LIFT THE UNIT WITHOUT FORLIFT PROTECTIONS

REMOVE 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.

INSTALLATION 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.

INST ALLATION ON A ROOF MOUNTING FRAME

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 7), 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 corner of frame.

-Measure frame diagonally from corner to corner as shown in figure 7. 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 :

local codes and regulations.

It must be securely fastened to the roof as per

Fig. 7

Page 40 - IOM / ROOFTOP BALTIC Series - 0704 - E

;

y

INST ALLATION ON A ROOF MOUNTING FRAME

When the frame is correctly positioned. It is essential to secure the assembly with a disconnected stitched welded seam (20 to 30mm every 200mm

) along the outside or by using an alternative method.

Fig. 8

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.

2

Outside of frame must be insulated with rigid type insulation; We recommend a minimum of 20 mm thick insulation (2 figure 8).

Check that the insulation is continuous, counter flash and seal around the frame as shown in (1-figure 8).

CAUTION : To be effective, the upstream must end below the drop edge (3 - figure 8).

Where pipes and electrical conduits extend through the roof, flashing must conform to local codes of practice.

The installer must comply to local authority standards and specifications.

ECONOMISER AND EXTRACTION

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 rain hood . Hoods is folded during transportation to limit risks of damage and must be unfolded on site as shown below on figure 9 :

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 :

multidirectional roofcurb will be installed

When horizontal flow configuration is required, the

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° 13), 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 53).

- 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.

VENTILATION BELT TENSION

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 16 mm per metre from centre to centre.

Check that according to the diagram below (figure 14), the following ratio remains the same.

A(mm) P(mm)

= 20

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).

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.

VENTILaTION : PULLEYS

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.

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.

MOTOR PULLEY INST ALLA TION AND REMOV AL

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.

Page 52 - IOM / ROOFTOP BALTIC Series - 0704 - E

VENTILaTION : PULLEYS

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 belt setting. To this effect, the motors are fitted with variable pulleys.

AIRFLOW BALANCING

Measure the absorbed amps

If the absorbed amps are greater 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 amps are lower 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 figure 15).

AIR SOCK CONTROL

FANST ART Operation

The use of air socks for space conditioning allows high air volumes to be distributed at low velocity and is becoming a common feature in many applications. To accommodate this trend, Air-sock control is offered which allows the air socks to be progressively filled with air on start up. BALTIC has been enhanced with an electronic device to soft start the fan. It takes up to 1 minute to go from 0% of air to full air flow.

This time can be divided in several stages:

- The aim of this first voltage input is to overcome the resistance of the transmission (Pulleys and belts): 0.5s and up to 100 rpm

- The second stage is to inflate the air sock: 5 to 30s. and 600 to 900 rpm

Finally the air sock is gradually pressurised during the last 5 to 30 second. The motor reaches nominal speed and the controller is bypassed.

START-UP

Phase rotation check

If the phase rotation is incorrect the FANSTART Control will display a fault ( Red LED). Two of the phases must then be inverted and start again the start up cycle.

The FANSTART control can also display a fixed red LED in two cases:

- Motor absent (6s)

- A phase is missing (6s)

Any adjustment of the FANSTART has to be done power stopped.

The motor speed control is achieve through a variation of the supply voltage of each phase at constant frequency.

The thermal overload limit on the motor imposes a current limitation during the acceleration stage. Hence if the selected slope is to steep, the predefined current limit can be reached: flashing red LED, adjust the potentiometer P3 and the controller will automatically reduce the voltage setpoint accordingly. Then once the current is back under the high current limit it carries on with the start up cycle.

The green LED switches off itself at the end of the FANST ART operation.

This time is divided in several stages:

- The aim of this first voltage input is to "take

off belts from the pulleys": 0.5s ("BOOST")

- The second stage is to inflate the air sock:

during 30s with approximately half nominal speed

- Finally the air sock is gradually pressurised during the last 30s. The motor reaches nominal speed and the controller is shunted, the motor being fed on line by the tension of the electrical network.

Safety

Excessive "slow down" limit

In the engine's acceleration phase, the red led flashing; the motor slows down in an excessive way and stops after 80s at fault (led red fixed).

Current protection of the Thyristor

The FANSTART will display a fault (red LED) if the current exceeds the thyristor current limits:

125A during 0.4s

87.4A during 2s 75A during 6s.

62.5A during 20s.

Start up sequence too long

If at the end of 80s the fanstart did not commutate the motor on the electrical network, the motor stops: fixed red led.

HEATING / HEATING HOT WATER COIL

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.

FREEZE PROTECTION

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

against freezing.

GL YCOL IS THE ONL Y 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.

HEA TING HOT WA TER COILS FROZEN DUE TO LOW AMBIENT CONDITIONS ARE NOT COVERED BY THE WARRANTY.

ELECTROL YTIC CORROSION

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

- Fill the hydraulic system and bleed the coil using the air vents. Check incoming hot water.

- Check the various connection for possible leaks

CLIMA TIC 50 SOFTWARE FEA TURES AND LOGIC

As a standard feature, CLIMATIC™50 provides 4 scheduling time zones per day on 7 days. On each of the 4 time zones, heating set point, cooling set point, minimum fresh air, humidity set point high and up, and even the different authorisations for cooling and heating can be adjusted. CLIMATIC™ 50 provides a choice of different remote displays depending on customer requirement and application of the system. As a standard feature, it is possible to set alarms (adjustable value low and high) on room temperature and humidity.

CONTROL SOFTW ARE LOGIC

With the CLIMATIC™ 50 Lennox is going away from the traditional step control

Capacity factor

It is used to determine the exact capacity required at any time in order to react quicker and more accurately to any change in demand. The capacity factor is a percentage of the total cooling or heating capacity.

Example: On a three circuit rooftop unit with two compressors running out of three has a capacity factor of 66% In the same way, a three circuit rooftop with a modulating electric heater running at 20% of its full capacity has a CF: CF = 25%+25%+25%+5% = 80%

The Capacity factor will increase, decrease, or freeze depending on the temperature difference between the set point and the room temperature but also on the way this room temperature is changing:

-1 Decreasing 60% ON ON OFF 0 Increasing 6 0% ON ON OFF

Reactivity .

The reactivity determines how fast the capacity factor should vary. It is given in: Percentage of capacity / Degree °C ( Room Temp. VS Set Point) / minute

Example : If the reactivity is set to 3 % / °C / min Then: Capacity factor can go from 0 to 30% in 10 minutes if Delta Room Temp. VS Set Point is 1°C Or capacity factor will go from 0 to 60 % in 4 minutes if Delta Room Temp. VS Set Point is 5°C

The reactivity can be adjusted with the CLIMATIC™ 50 The larger the reactivity the faster the rooftop will react to a change.

The next table shows the effect of a change of the reactivity on the capacity factor: This shows that by increasing the reactivity, the unit reaches the set point quicker but the energy consumption (capacity factor) is larger.

control software features

Heating priorities

It is possible to set heating priorities depending on the outdoor temperature. For compressors: refer to the instructions 3611, 3612,

3613. For electrical heater: refer to the instruction 3721.

Example: It could be decided based on energy costs, that on a dual fuel unit, it should run in heat pump mode when the temperature is above 0°C and switch to gas burner below that point.

Staggered start

After a power cut, the units can be made to restart one after the other to prevent any current surge. There is no need for a link between the units, they just have to be given an address during commissioning and they will restart 10 seconds x their "address number" after the power is switched back on.

Example: If a unit is given the address N°3 it will be switched-on 30 seconds (3 x 10sec) after the power is switched back on.

Fresh air adjustment and calibration on Economiser

The actual fresh air volume brought into the system is not always proportional to the percentage of opening of the fresh air damper. That is particularly true when the return air duct system has been sized to produce excessive pressure drop. This often results in bringing into the system an excessive amount of fresh air, hence increasing the running cost of

the system. The control of fresh air is now achieved through the use of

three temperature sensors : One in the supply air flow, one in the return air and one for the outdoor temperature.

This new feature patented under INPI 91.033.063 allows the unit to start the defrost cycle only when required. This is achieved through the measurement of the temperature difference between the coil and the outdoor.

The defrost will be initiated shortly after the Climatic50 has located the largest gradient in the curve.

The defrost cycle ends when one of these two condition is completed whichever comes first :

+ Three defrost cycles. + 6 minutes.

Alternate defrost

All dual circuits Baltic units have "Alternate Defrost" as a standard feature. When one circuit is going through a defrost cycle the second circuit is running in heat pump mode. This reduces the need for costly electric heater to maintain the supply air temperature to an acceptable level of comfort during the defrost cycles.

CO² Sensor

Where a CO² sensor is connected to the unit, the value of the fresh air minimum is calculated according to the CO² ratio. The value measured by the sensor can be read in variable 2132. Setpoint 3514 defines the number of ppm up to which the fresh air minimum is still achieved. Setpoint 3515 defines the number of ppm from which 100% fresh air is used.

20% 40% 60% 80% 100%

Damper position

Using these three sensors, the Climatic50 will calculate and memorise the exact percentage of fresh air for each position of the damper.

The calibration sequence will take place periodically when all cooling or heating inputs are off. The instruction 3516 permits us to avoid the calibration.

This is a remote controller for non-technical customer. This display gives information such as running mode status of the fan, set point, % of fresh air and outside air temperature. It can be used to set or change the scheduling of the different time zones, the temperature set point, and the % of fresh air for each zone. It also has the capacity to set a 3 hours override and to force the unoccupied mode for up to 7 days. It displays the real time clock and different faults signals.

Type FSTN graphic Back light: Green LEDs

Resolution 120x32 pixels Power Supply

Voltage from main Climatic board. Max power: 0.8W

Installation

The DC50 is designed to be mounted on the wall. * Fit the cable from the DT50 board through the back piece * Fasten the back piece to the wall using the rounded head screws supplied in the packaging * Connect the cable from the main board on the RJ12 plug on the back of the DC50 display * Fasten the front panel on the back piece using the flush head screws supplied Finally fit the click-on frame

Jumpers:

"Displays" are supplied directly by the Climatic board with 30Vdc. Take particular care at the path this 30V is taking when several boards are being used.

J14 and J15 can switch on or off the direct current from the power supply:

J14 and J15 set between1-2

Connectors A, B, C and screw connector SC are in parallel. Power supply available to all connectors.

J14 and J15 set between2-3

Connectors B and C are in parallel but line 1 and 6 don't reach connector A and screw connector SC.

"Displays" connected to these ports will not be powered. If J14 and J15 are set in different positions the "terminal

connection board" DT50 DOES NOT WORK.

NOTE:

When a shielded wire is used the metallic case of the "Terminal connection box" DT50 must be earthed.

_ 1 : DC50 : Master slave mode "total" The master gives the ventilation order, and its set point to

all other rooftops. _ 2 : DC50 Temperature : Master slave mode

"temperature" The master gives the ventilation order and its room

temperature/humidity to all other rooftops, but they have their own set point.

_ 3 : DC50 Average : Master slave mode "average" The master gives the ventilation order and the room

temperature/humidity used by all rooftop is the average of all rooftop. Each rooftop has its own set point.

_ 4 : Master/Slave Temperature : Master slave mode "temperature"

The master gives its room temperature/humidity to all other rooftops, but they have their own ventilation order & set point.

_ 5 : Master / Slave Average : Master slave mode "ave- rage"

The room temperature/humidity used by all rooftop is the average of all rooftop. Each rooftop has its own ventilation order & set point.

_ 6 : Master / Slave Cooling / Heating : Master slave mode "cooling/heating"

All rooftop are stand-alone but the slaves have to have the same running mode as the master (Cooling or heating).

_ 7 : Back-up mode One rooftop is the back-up unit and will operate if any of the

other rooftop has a failure. _ 8 : Rolling Back-up mode Same as above, except the "back-up" unit will be different

each Tuesday. On top of that, the outside temperature/ humidity given to all rooftop can either be the average of rooftop or be the external humidity/temperature of the master, making possible the use of a single "weather station" for the whole site.DS50 Comfort Display / DC50 Service Display
