1. Important Carefully read all the information in this manual before removing the packaging, before handling, assembling, positioning, commissioning of the machine and before performing any work on the model. If in doubt contact Modine. This manual is an integral part of the product and must be kept for the entire life of the unit. Modine declines all responsibility for damage to persons and property caused by failure to follow all instructions contained in this manual.
• EU-OEL: 9000 mg/m , 5000 ppm as TWA. A concentration above 100000 ppm may cause pulmonary oedema and be fatal. Continuous monitoring of CO concentration is recommended when installing models in confined spaces. 1.24 If you have any doubts or queries, please contact Modine or the dealer. 2.
3. Identification For any communication, request for assistance or spare parts, please provide the model name and serial number shown on the data plate: Figure 1 4. Inspection - Storage Upon receipt of the model immediately check its state of integrity; immediately dispute with the transport company any damage.
The model must be stored in its original packaging in a place that is protected and away from weathering. Do not place any other material on top of the packaging. If the model is allowed to be stacked, follow the instructions on the packaging. If a motor fan is switched OFF for a long period of time, it must be switched ON for at least 2 hours every month to remove any traces of condensation that may have formed inside the motor.
6. Installation conditions The model described in this manual is a component of a system and must be installed by authorised personnel only. Access to the unit for any type of intervention must be reserved to personnel qualified to operate the system, in accordance with the regulations in force.

8. Recommendations for a proper access to the model Access Remove R1 drain connection. Verify that drain pan L1 is free from ice build-up before removing it by unfastening the screws “A”. Loosen self-threading screws “B”, without removing them completely, then slip off the side panel L5. Reassembling Reposition the side panel L5 and fasten with screws “B”.
9. Wiring diagrams Motor-fan connection diagram Important. The motors are equipped with inner thermal protection with automatic reconnection. Before using motor speed control systems verify the compatibility with the motors. Non compatible systems may damage motors or incre- ase noise level; Modine will not be responsible for model performance with speed control systems. For fans equipped with thermal contacts (TK), these must be connected to the control circuit.

10. Checks to be performed before start-up With main switch open and padlocked (“0-OFF” position): 10.1 Tightening of all the electrical connections. 10.2 Levelling and checking the solidity of the supporting structure. 10.3 Correct fastening of panels and components, paying particular attention to the correct fastening of the fan guard grille. 10.4 Verification of spaces for maintenance.
12. Maintenance 12.1 Checks, inspections and maintenance must be carried out by specialised and authorised personnel. 12.2 During the operations of maintenance, repair and cleaning, always use personal protective equipment (e.g. gloves sufficiently resistant to mechanical hazards) to reduce the risk of injury in the event of contact with the sharp edges of the metal sheets or with the finned pack.
Page 21
correctly reset wiring and existing fastening systems to avoid possible movement during operation. 12.14 After every maintenance work, carry out the checks before commissioning according to Chapter 10 and after commissioning according to Chapter 11. 12.15 When repairing the system, be aware that even with non-flammable refrigerants (e.g. CO is used as an extinguishing medium), some traces of lubricating oil may be entrained and thus flammable mixtures may be created.

13. Residual risks 13.1 The equipment presents a number of risks that have not been fully eliminated from the design point of view or through the installation of adequate protections. Based on such risks, it is reported which PPE should be used by the operators or which behaviours and procedures should be adopted.

Headers can reach low temperatures, avoid contact. Airflow from fans can cause discomfort to personnel and damage to property. Any use other than that specified in this manual is considered incorrect. During operation of the equipment, no other types of work or activities are permitted that are to be considered as incorrect and that in general may entail risks for the safety of persons and damage to property.
The PPE used must comply with the directives of the product and bear the CE marking (for the European market). The definitions of the phases of life of the equipment are described in the following table. Phase Description Transportation It consists of transferring the equipment from one location to another through the use of suitable means. It consists of transferring the equipment from and on the means used for transportation and movements Handling within the plant.
