WARNING - 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.
SAFETY
The safety information contained in this manual is provided as a guide for the safe handling of this installation. LENNOX does not vouch for the completeness of this information and can therefore not accept liability for any possible omissions.
In the roof tops, heat is being transported by a pressurised refrigerant, with changes in pressure and temperature. For air cooled roof tops, fans have been provided to discharge heat into the environment. The protection of operating and maintenance personnel was central in the design of the roof top. Safety features have been included to prevent excessive pressure in the system. Sheet metal parts have been fitted to prevent inadvertent contact with (hot) pipes. For air cooled roof tops, the fans are equipped with protective grids and the electrical control panel is completely touch-proof. This excludes some parts operating at a safe voltage (< 24 Volt). The service panels can only be opened using tools.
The electrical control panel is completely touch-proof. This excludes some parts operating at a safe voltage (< 50 Volt). The service panels can only be opened using tools.
Notwithstanding that the roof tops are equipped with extensive safety and protection features, the utmost care and attention is needed when carrying out operations on the machine. Furthermore, ear protection should be worn when working on or in the vicinity of the roof tops. Operations on the cooling circuit or electrical equipment should be carried out by authorised personnel.
It is essential to follow non exhaustive recommendations hereunder:
• Never work on a unit that is still energized.
• Any manipulation (opening or closing) of a shut-off valve must be carried out by a qualified and authorised engineer. These procedures must be carried out with the unit shut-down.
• Never work on any of the electrical components, until the general power supply to the unit has been cut. During any maintenance operations on the unit, lock the power supply circuit in the open position ahead of the machine. If the work is interrupted, check the lock before resuming the work.
WARNING: Even if the unit has been switched off, the power circuit remains energized, unless the unit or circuit disconnect switch is open. Refer to the wiring diagram for further details.
• For some units, a separate 220V power supply may exist, check the electrical wiring for more informations
• In case of maintenance operations on fans (grills replacement …) ensure that the power is shut off to avoid automatic restart.
• Before the opening of the refrigerant circuit, check the pressure with manometers or pressure sensors, and purge the circuits.
• Never leave a unit stopped with valves closed on the liquid line, refrigerant could be trapped and the pressure would rise.
• All installation parts must be maintained by the personnel in charge, in order to avoid material deterioration and injuries to people.
Faults and leaks must be repaired immediately. The authorized technician must have the responsibility to repair the fault immediately.
Each time repairs have been carried out to the unit, the operation of the safety devices must be re-checked.
• Follow guidance and recommendations given in safety and machine standards such as EN378, ISO5149, etc
• Do not use oxygen to purge lines or to pressurize a machine for any purpose. Oxygen gas reacts violently with oil, grease, and other common substances.
• Never exceed the specified maximum operating pressures. Verify the allowable maximum high- and low-side test pressures by checking the instructions in this manual and the pressures given on the unit name plate.
• Do not use air for leak testing. Use only refrigerant or dry nitrogen.
• Do not unweld or flame cut the refrigerant lines or any refrigerant circuit component until all refrigerant (liquid and vapour) has been removed from roof top. Traces of vapour should be displaced with dry air nitrogen. Refrigerant in contact with an open flame produces toxic gases.
• Do not siphon refrigerant
• Avoid spilling liquid refrigerant on skin or splashing it into the eyes. Use safety goggles. Wash any spills from the skin with soap and water. If liquid refrigerant enters the eyes, immediately and abundantly flush the eyes with water and consult a doctor.

High temperatures Electrical Voltage Rotating parts Sharp parts
Regularly check that the warning labels are still in the correct positions on the machine and replace them if necessary.
!
Warning
:
1.
Attention: The high-pressure safety switches are essential elements which guarantee the system remains within the admissible operating limits. Before switching on the installation, always ensure all electrical connections are correct on these elements which are used to isolate the electrical power supply to the compressor(s) they protect. Carry out a test to ensure the electrical power supply is effectively isolated when the pressure switch attains its set value.
2.
In case of installation in a seismic zone or in a zone which may be effected by violent natural occurrences such as storms, tornados, floods, tidal waves, etc…, the installer and/or operator will refer to valid standards and regulations in order to ensure the devices required are available as our units are not designed to operate under such conditions without prior precautions.
3.
The equipment is not designed to resist fire. The installation site will therefore have to respect valid standards with regard to protection against fire (emergency instructions, map…).
4.
In case of exposure to corrosive external atmospheres or products, the installer and/or operator shall take the necessary precautions to avoid damage to the equipment and will make sure the equipment provided has the necessary and sufficient anticorrosion protection.
5.
To respect a sufficient number of supports for the piping according to their size and weight under operating conditions and to design the piping to avoid a water hammer phenomenon
6.
For technical reasons, it is not possible to carry out hydrostatic tests on all our units so leak tests are carried out as a compensatory measure. (The entire circuit is checked using leak detectors). For machines charged with refrigerant, at the end of the test, an HP test is carried out in the factory to make sure the pressure switch is working properly.
7.
Before any work is carried out on the refrigeration circuit, the dry air or nitrogen pressure our units are supplied with must be released (For units not charged with refrigerant in the factory.)
8.
The emissions of refrigerant via the safety relief valves must be channeled to the exterior of the machine room. The outlet relief valve will have to be sized in compliance with EN13136.
9.
Installation and maintenance of these machines must be carried out by personnel qualified to work on refrigeration equipment.
10. All interventions must be carried out in conformity with valid safety regulations (e. g.: NF EN 378), as well as the recommendations indicated on the labels and handbooks provided with the machine. All actions shall be taken to avoid access of unauthorized persons.
11. It is essential that any pipework or other components of the refrigeration circuit hazardous to people because of their surface temperature are insulated or identified.
12. Ensure that the installation zone (room or area) of the machine has restricted access and ensure the good condition of the covering.

DELIVERY CHECKS
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. The drains must be installed in vertical position.
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. The surface on which the equipment is to be installed must be flat. (See next paragraph)
• 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 installing two units side by side or close to each other as this may restrict the airflow to the condensers, and could limit the access for maintenance purposes.
• Uneven surfaces are prohibited. The surface must be flat and respect a maximal flatness of 0.5mm per linear meter (in both directions length and width).
• The surface must support continuously the entire area of the unit/curb (no rubber pad, no spring, no block…).
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 insulated.
• To avoid condensation problems, make sure that all pipes are insulated according to the temperatures of fluids and type of rooms.

In case of full options control panel, the access to connect the power cable to the main switch can be limited. Therefore a removable hatch is available at the back of the control board (accessible from the ventilation panel). When the cable connection is finished, it’s important to put the hatch back in its initial position.

WATER COOLED UNITS
WATER SOURCE HEAT PUMP ONLY
Water connections
The water circulating pump will be preferably installed upstream so that the evaporator/condenser will be subjected to positive pres- sure. Inlet and Outlet water connections are indicated on the certified drawing sent with the unit or shown in the sales brochure.
The water pipes connected to the unit must not transmit any radial or axial force or any vibration to the heat exchangers.
It is important to follow non exhaustive recommendations hereunder:
•Comply with the water inlet and outlet connections shown on the unit.
• Install manual or automatic air purge valves at all high points in the circuit.
• Install a safety valve as well as an expansion tank to maintain the circuit pressure.
• Install thermometers in both the inlet and outlet water connections.
• Install drain connections at all low points to allow the whole circuit to be drained.
• Install stop valves, close to the inlet and outlet water connections and easily accessible for maintenance.
• Use flexible connections to reduce vibrations transmission.
• After testing for leaks, insulate all pipe work, to reduce thermal leaks and to prevent condensation.
•If the external water pipes are in an area, where the ambient temperature is likely to fall below 0°C, insulate the piping and add an electric heater.
• Ensure full earthling continuity
A drainage plug is located at the base of the evaporator. A drainage pipe may be connected to this to enable drainage of evaporator water for service operations or for seasonal shut down.
Connections at the inlet and outlet are Victaulic type.
Water analysis
The water must be analysed; the water circuit installed must include all items necessary for treatment of the water: filters, additives, intermediate exchangers, bleed valves, vents, isolating valves etc... depending on the results of the water analysis.
We do not advise operation of the units with open loops which can cause problems with oxygenation, or operation with untreated ground water.
!
Use of untreated or improperly treated water can cause deposits of scale, algae and sludge or cause corrosion and erosion. It is advisable to call in a qualified water treatment specialist to determine what kind of treatment will be necessary. The manufacturer cannot accept liability for damage caused by the use of untreated or improperly treated water, salt water or brine.
Here are our non exhaustive recommendations given as an indication:
• No NH4+ ammonium ions in the water, they are very detrimental for copper. <10mg/l
• Cl- Chloride ions are detrimental for copper with a risk of perforations by corrosion by puncture. < 10 mg/l.
• SO42- sulphate ions can cause perforating corrosion.< 30 mg/l.
• No fluoride ions (<0.1 mg/l).
• No Fe2+ and Fe3+ ions with dissolved oxygen. Dissolved iron < 5 mg/l with dissolved oxygen < 5 mg/l. Over those values, it means a corrosion of steel which may generate a corrosion of copper parts under deposite of Fe – this is mainly the case with shell and tube heat exchangers.
• Dissolved silicon: silicon is an acid element of water and can also lead to corrosion risks. Content < 1mg/l.
• Water hardness: TH >2.8 K. Values between 10 and 25 can be recommended. This will facilitate scale deposit that can limit corrosion of copper. TH values that are too high can cause piping blockage over time.
• TAC< 100.
• Dissolved oxygen: Any sudden change in water oxygenation conditions must be avoided. It is as detrimental to deoxygenate the water by mixing it with inert gas as it is to over-oxygenate it by mixing it with pure oxygen. The disturbance of the oxygenation conditions encourages destabilisation of copper hydroxides and enlargement of particles.
• Specific resistance – electric conductivity: the higher the specific resistance, the slower the corrosion tendency. Values above 3000
Ohm/cm are desirable. A neutral environment favours maximum specific resistance values. For electric conductivity values in the order of 200-6000 S/cm can be recommended.
• pH: pH neutral at 20°C (7 < pH < 8)
If the water circuit must be emptied for longer than one month, the complete circuit must be placed under nitrogen charge to avoid any risk of corrosion by differential aeration.

Antifreeze protection
Use glycol/water solution
!
ADDITION OF GLYCOL IS THE ONLY EFFICIENT WAY TO PROTECT AGAINST FREEZING
The glycol/water solution must be sufficiently concentrated to ensure proper protection and prevent formation of ice at the lowest outdoor air temperatures expected on an installation. Take precautions when using non-passivated MEG antifreeze solutions (Mono Ethylene Glycol or MPG Mono Propylene Glycol). Corrosion can occur with these antifreeze solutions with oxygen.
Drain the installation
!
It is important to make sure that manual or automatic air bleeders are installed at all the high points of the water circuit.
To enable drainage of the circuit, make sure that drain cocks are installed at all the low points of the circuit. To drain the circuit, the drain cocks must be opened and an air inlet ensured.
Note: air bleeders are not designed to admit air.
FREEZING OF A HEAT EXCHANGER DUE TO COLD WEATHER CONDITIONS IS NOT COVERED BY LENNOX WARRANTY.
Electrolytic corrosion
!
We would like to draw your attention to the problems of corrosion due to electrolytic corrosion caused by an imbalance between earthing points.

HEAT RECOVERY - GENERAL DESCRIPTION
Heat recovery modules have following interests:
• in winter season and heating mode, the heat in the extract air is exchanged with the fresh air ;
• conversely, in summer season and cooling mode, the heat of the fresh air is transferred to the extract air.
HRMV and HRMH are two plates heat exchanger modules, that differ from each other by their horizontal or vertical configuration.
TRMO is a thermodynamic heat recovery module, included in the machine. Its main interests are:
• a variable fresh air rate from 25 to 100%,
• a high COP in winter when pre-heating the fresh air due to a favorable evaporating temperature, especially with high air flow rate;
• a high EER in summer when pre-cooling the fresh air due to a favorable condensing temperature, especially with high air flow rate.
For those reasons, TRMO will be more suitable than HRMV/HRMH in areas where the difference between indoor temperature and outdoor temperature is low. For example, in Mediterranean areas, where winter temperatures are not very cold or summer temperatures are not very high.

THERMODYNAMIC HEAT RECOVERY - INSTALLATION
1. REFRIGERATION CIRCUIT
Frigorific components access:
Compressor is located in the fix condenser part. Its access for electrical checking and pressure taps (HP and LP) is made through the screwed access door behind the hinged coil.
4-way valve, thermostatic expansion valve, dryer, and sensors are located on the e-
Drive™ supply compartment.
Electrical components:
• For D and E-box, specific TRMO components are located in the electrical box.
• For C-box, specific TRMO components are located on the back of the electrical box, and can be accessible from the supply e-Drive™ compartment.
2. COMMISSIONING
Electrical connections:
• All wire connections are factory made.
Starting up:
• CLIMATIC™ configuration:
- Power the unit
- Check the configuration of the CLIMATIC™ with the DS in expert mode.
• Flow rate settings:
Make sure that both supply and exhaust air flow are balanced. See section EBHO or ERVF. Balancing is correctly set if:
- with Test = 'B.Nom 100%': at 100% fresh air, set the exhaust Flow 3864 = supply flow 3333;
- then switch Test = 'B.Nom 0%':
1. reduce coefficient 3866 until the louvers are closed;
2. then if the flow (supply and exhaust) is far from the previous flow settings, set coefficient 3335;
3. finally, repeat step 1 and 2 to obtain a constant flow whatever the fresh air mode.
- same settings have to be realized for reduced flow - 3334 and 3865.
WARNING! During the settings, wait until the economizer is fully closed or opened, since it takes 1-2 minutes to switch.
• Start the TRMO circuit (circuit 3): switch Test='C3--Cool'
- check the sense of rotation of the circuit 3 compressor;
- check frigorific values (HP, LP, overheating and subcooling).
• Repeat the last operations with Test='C3--Heat'

COMMISSIONING
!
WARNING: commissioning must only be carried out by trained refrigeration engineers whom qualification certificates are compliant with the local regulation
Before turning on the power
WARNING: ensure that the power supply includes 3 phases with no neutral
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 displayed on the name plate.
Wire connection tightness checks
WARNING: check the wire connection tightness
Check the following wire connections for tightness:
• Main switch connections,
• Mains wires linked to the contactors and circuit breakers
• Cables in the 24V control supply circuit.
WATER LOOP CHECK LIST BEFORE START-UP
Check that all drain and purge plugs are in place and well tightened prior to fill the installation with water or brine. Before proceeding with start-up, even for a test of short duration, check the following points, after having made sure that all the valves on the refrigeration circuit are fully open (discharge valves and liquid valves).
• The liquid pump(s) and other apparatus interlocked with the unit (coils, air handling units, dry coolers, cooling towers, terminals such as fan coil units, etc.) are in working order as required by the installation and according to their own specific requirements. Place all water valves and refrigerant valves in their operating positions and start the water circulating pumps.
• the condenser water circuit must be ready to operate, filled with water, pressure tested, bled, filter cleaned after 2 hours of operation of the water pump.
• start the pump(s) check the flow of liquid to be cooled through the heat exchangers: note the inlet and outlet water pressures, and, using the pressure drop curves, calculate liquid flow by applying the following formula:
Actual flow
Q = Q1 x
√(P2/P1)
Where
P2 = pressure drop measured on site
P1 = pressure drop published by LENNOX for a liquid fl ow of Q1
Q1 = nominal flow
Q = real flow
Adjust the condenser circuit water flows (via regulating valves, pump speed position..) to come close to the designed conditions
(LENNOX software).
OIL CHARGE
All units are delivered with a complete oil charge, and there is no need to add any oil before start up or afterwards. Overcharging with oil can cause serious problems on an installation, particularly for the compressors.

COMMISSIONING
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. 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.
WARNING: a compressor rotating in the wrong direction will fail shortly.
If the fan turns in the wrong direction (the right direction is shown below), 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.
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.
If the readings on the fan are outside the specified limits, this usually indicates excessive air flow which will affect the life expectancy. In this case reduce rpm using eDrive™.
While starting the unit, fill in the check list sheet of this manual to be sure that the unit correctly installed and ready to operate.
• Check the current values per phase on each fan motor.
• Check the current values per phase on each compressor motor.
• Check suction and discharge pressures and compressor suction temperature.
• Check chilled liquid entering and leaving temperatures if water cooled unit
• Check outdoor air temperature and indoor temperature
• Check liquid refrigerant temperature at the condenser outlet.
• Check if DAD is ON.
These verifications should be made as quickly as possible with a stable cooling load, i.e. the cooling load of the installation should be the same as the capacity developed by the unit. Measurements taken without heeding this condition will result in unusable and probably wrong values.
These verifications can only be made once the proper operation of all safety devices and unit controls has been established.
Check if the customer's air ducts are open to be sure the unit is not running with ducts closed. In addition it is needed to check if the airflow and available static pressure are in accordance with the unit.

eDrive™ VENTILATION
eDrive™ fan inverter configuration (AC version)
eDrive™ Inverter configuration is prepared in the factory to communicate with CLIMATIC™ & to be configured specifically for the customer machine.
eDrive™ Fan inverter parameters are configured via the CLIMATIC™ unit configuration.
This configuration is selecting the proper parameters to run eDrive™ in its operating range depending on fan type & motor size.
If ever, the Inverter loose fan control (No Fan or Wrong fan speed & Compressor or Heating stay on), one may check the Inverter configuration as below:
“0.0” will be displayed in this case on the Inverter instead of the regular “0” or “xxx” rpm
Switch to unlock mode:
F700 = 0
F732 = 0
On Inverter, set the TYP parameter to 3 value. (reinitialize the Inverter to the default values) then configure the following setpoints:
F800=1
F801=0
F802=11
F803=0
Then switch OFF the whole machine & then switch ON.
Then the CLIMATIC™ is going to send all the proper machine configuration to Inverter (motor size, fan type, Imax, safety parameters) .

FRESH AIR HOOD
Installing
The fresh air hood has to be opened and secured during commissioning.
The 3 parts of the fresh air hood have to be assembled thanks to self taping screws delivered in the spare part box
Check the proper position of the black seal on the top of the hood cover.
Wind direction
The prevailing wind has to be taken into account while choosing the machine position on the building roof.
It’s highly recommended to avoid putting the fresh air hood in the prevailing wind direction to avoid water ingress risks.
If this is not possible please contact us to require specific water droplet strainer in the hood section.
WARNING: the fresh air hood cover can hurt your head if you don’t pay attention while turning around the unit.
BALTIC-IOM-1711-E -48-
FILTERS
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 clean ones in.
The CLIMATIC™ controller can monitor the pressure drop across the filter
The following set points can be adjusted depeding on the installation.
• “Airflow” in page 3343 = 25Pa by default
• “No filter “ in page 3344 = 50Pa by default
• “Dirty Filter” in page 3345 = 250Pa by default
The actual pressure drop measured accross the coil can be read on the CLIMATIC™ Display in menu 3342.
The following faults may be identified
• Fault code 001 AIRFLOW FAILURE, if measured ΔP across the filter and coil is below the value set in page 3343
• Fault code 004 DIRTY FILTERS, if measured ΔP across the filter and coil is above the value set in page 3344
• Fault code 005 MISSING FILTERS, if measured ΔP across the filter and coil is below the value set in page 3345.

HEATING OPTIONS
Hot water coils
The hot water coil is fitted with a three way proportional valve . 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.(Arrow on the picture)
• Fill the hydraulic system and bleed the coil using the air vents. Check incoming hot water flow rate.
• Check the various connections for possible leaks
Maximum working pressure:
Maximum working temperature:
8 Bars
110 °C
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 against freezing under winter conditions.
Warning: glycol based fluids may produce corrosive agents when mixed with air.
Drain the installation
You must ensure that the manual or automatic air vents have been installed on all high points in the system. In order to drain the system, check that all the drain valves 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 damaged by electrolytic corrosion is not covered by the warranty.

HEATING OPTIONS
Electric heater
WARNING: electric heater is connected heater to mains power – risk of electrical shock – switch off the unit prior to open this section
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/cm 2 .
It is protected as standard, against overheat via a high temperature overload protection set at 98°C and located less than 150mm after the heater itself.
There are two sizes available for each size of unit:
S: Standard heat
H: High heat
The standard heat electric heaters are staged control with 50% or 100%. The high heat version is controlled through a fully modulating triac.

WARRANTY
Terms and conditions
In the absence of any other written agreement, the guarantee shall only apply to design faults which occur within a 12 month period
(warranty period).
The warranty period starts on the date of commissioning and at the latest six months after the delivery of the Rooftop.
Anti-corrosion warranty
10 year warranty terms and conditions for corrosion to the Rooftop casing:
LENNOX shall guarantee the casing of its Rooftop units manufactured against corrosion for 10 years commencing from the date of delivery of the material.
The warranty shall not apply in the following cases:
1. If the corrosion of the casing is caused by external damage to the protective layer such as scratches, projections, abrasion, impacts etc...
2. If the casing is not kept continually clean in the course of maintenance work or by a specialist company,
3. If the casing is not cleaned and maintained in accordance with regulations,
4. If the Rooftop units are installed on a site or in an environment which is known to be corrosive, unless a special protective coating has been applied by the owner for these applications, which has been recommended by a competent body not linked to the owner and after carrying out a study of the site.
5. Nevertheless the LENNOX coating is highly resistant to corrosion, the warranty will not be applied for rooftop installed at less than
1000 m away from the sea
Note: With the exception of the casing, the rest of the machine is covered by the warranty of our general terms of sale.
Do not confuse the warranty with maintenance
The warranty will only apply if a maintenance contract has been signed, starting from the date of commissioning, and if the maintenance contract has actually been performed
The maintenance contract must be made with a specialist, competent company.
The sole effect of any repair, modification or replacement of an item during the warranty period must be to extend the material's warranty period.
Maintenance must be carried out in accordance with regulations.
If a spare part is supplied after the expiry of the warranty period, it shall be guaranteed for a period equal to the initial warranty period and will be subject to the same conditions.
We recommend for a contract four inspections per year (every three months), before the start of each season, in order to check the operation of the equipment in the various operating modes.
Lifetime of the equipment
The refrigerating system is designed for a lifetime of at least 10 years if the safety and maintenance instructions are strictly respected.
The lifetime of the equipment may be renewed if the periodic requalification certificate is validated by the expert (authorized body or DREAL)
Disposal of the equipment
Equipment shut-down and recuperation of oil and coolant must be carried out by qualified personnel conform to the recommendations of standard NF EN 378.
All elements in the refrigeration system such as refrigerant, oil, coolant, filters, dryers and insulating materials must be recuperated, re-used and/or disposed of in a correct manner (see NF EN 378 part 4). No materials may be discarded into the environment.
BALTIC-IOM-1711-E -75-
MAINTENANCE PLAN
Rooftops are generally placed on the roof but can also be installed in technical rooms. These units are very robust but a minimum regular maintenance is required. Some moving parts in the units can suffer from wear and tear and must be checked regularly (belts).
Other parts can get clogged by dirt carried in the air (filters) and must be cleaned or replaced.
These units are designed to produce cooled or heated air through the use of a refrigeration vapour compression system, it is therefore imperative to monitor the refrigeration circuit operating pressures and check the pipe-work for leaks.
The table below, details a possible maintenance plan, including the operations to be carried out and the periodicity at which they must be accomplished. It is recommended to follow such a plan to keep a rooftop unit in good working order. Regular maintenance of your rooftop will extend its operating life and reduce operating faults
Symbols and Legend :
X Operation which can be carried out by on-site maintenance technicians.
◆
Operation which must be carried out by qualified refrigeration personnel, trained to operate on this type of equipment.
Note:
• Times are given for information purpose only and may vary depending on the unit size and type of installation.
• Coil cleaning must be carried out by qualified personnel using appropriate methods that won’t damage the fins or the tubes.
• It is recommended to keep a minimum stock of common replacement parts in order to be able to carry out regular maintenance operations (i.e. filters). You can contact your local LENNOX representative which can assist you in establishing a parts list for each type of equipment.
• The access ports to the refrigeration circuits MUST be leak checked every time gauges are connected to the service ports.
