1 - INTRODUCTION

1.1 General safety instructions

This appliance must only be used for the function for which it was designed "Adiabatic cooler /

humidifier". Any other use is to be considered improper and dangerous. Franco s. r. l. cannot be held

responsible for any damage resulting from improper, incorrect and unreasonable use, such as, for

example:

- installation errors

- incorrect power or water supply

- unauthorised mechanical or electrical modifications

- removal of guards or safety devices

- lack of maintenance

- use of non-original spare parts

- non-compliance with the operating and maintenance instructions

- When opening the packaging, check that the appliance is intact and does not show any damage or

deformation of the plastic parts. If this is the case, do not install the appliance and contact the service

department.

- Before connecting the appliance, make sure that the data on the rating plate (voltage, frequency, etc.)

correspond to those on the mains. The technical data label is located on the bottom side of the appliance

(see par. 1.9).

- Comply with the safety rules indicated for electrical equipment, and in particular:

•Follow the operating and maintenance instructions for the appliance.

•Do not place objects on the cooler.

•Prevent children and/or physically or mentally unfit persons from using the device without proper

supervision;

•Do not touch the cooler during operation.

•Never immerse the appliance in water or any other liquid, or hit it with pressurised water.

•Do not place any objects inside the appliance.

•Do not use accessories, spare parts and components not intended for or supplied by the

manufacturer.

•Avoid touching the device with wet or damp hands.

•Do not pull power cables or expose them to risk of shearing.

•In the event of a fault or malfunction, switch off the appliance immediately and disconnect the

power supply. Do not attempt to open or tamper with the appliance: contact the technical service.

•Do not attempt to fill or empty the drip tank manually when the appliance is in operation.

•Do not remove the guards during use.

•Do not install the device in explosion hazard areas.

1.2 Warnings for the correct disposal of the product (EU)

Pursuant to European Directive 2012/19/EU:

At the end of its useful life, the appliance must be delivered to the appropriate separate

waste collection points set up by the local authorities, or to retailers who provide this

service. Disposing of the product separately avoids possible negative consequences for

the environment and health, and allows the materials from which it is made to be

recovered, thus saving energy and resources. To emphasise the obligation to dispose of

electrical and electronic equipment separately, the product is marked with a crossed-out

wheeled bin.

The manual is divided into chapters. Where necessary, pictograms are used to indicate the specific type

of operator for whom the chapter is intended (e.g. mechanical maintenance, service, etc.).

The sequence of chapters follows the phases of the machine's life.

To facilitate understanding of the text, terms, abbreviations and pictograms are used, the meaning of

which is indicated below.

ABBREVIATIONS

Cap. = Chapter

Par. = Paragraph

1.4 Keeping and updating the instruction manual

The manual is an integral part of the machine: it must therefore be stored with care and must accompany

the machine in all changes of ownership. Handle the manual with care, with clean hands and do not

place it on dirty surfaces. Do not remove, tear or arbitrarily modify any part. Keep the manual away from

moisture and heat and in the vicinity of the machine to which it refers.

Further copies of the instruction manual can be obtained from support@francosrl.com.

The manual contains the instructions for the machine model and version to which it is attached. In the

case of authorised modifications to installed machines, which involve the modification of parts of the

instruction manual, it is the manufacturer's responsibility to send the customer the parts affected by the

modification. The user must replace the old parts with the new parts in the manual he has.

The manufacturer is responsible for the original version in Italian; in case of doubts about the

translations, please refer to the Italian language and contact the manufacturer (support@francosrl.com)

for the necessary checks.

1.7 Applications

The ROOF COOLER is an evaporative cooler for large rooms, such as workshops, industrial

departments, commercial and civil buildings, agricultural and livestock premises, etc., which works

based on the principle of adiabatic cooling. Warm air is drawn in from outside, flows across the high-

efficiency evaporative panels and comes into contact with the water flowing through the panels from top

to bottom. The evaporation removes heat from the air and naturally lowers its temperature. The fresh

air is then conveyed and distributed to the space to be cooled through a duct. The cooling capacity

depends on the temperature, room humidity and air distribution.

As well as a cooler, the unit can also be used as a humidifier for large room volumes, in industrial, civil,

agricultural and livestock applications, or as a simple ventilator, when cooling or humidification is not

necessary.

The materials used guarantee reliability and durability, even in the most critical environments.

This machine must only be used for the purpose

for which it was designed: "Adiabatic cooling/humidification". All

other uses are considered improper and therefore potentially

dangerous.
