Desert cooler (DCP), the Evaporative Cooler uses the principle of adiabatic cooling (water evaporation) to
cool the air.
The heart of DCP is cassettes made from evaporative media. Water is supplied to the top of the evaporative
media via distribution headers. The water flows down the corrugated surface of the media. As the warm and
dry air passes through the media it evaporates a proportion of the water and thus produces cold air. The energy
that is needed for the evaporation is taken from the air itself. The air that leaves the DCP is therefore cooled
simultaneously without any external energy supply for the evaporation.
Axial fan ensures even distribution of the cold air into the ventilation duct or directly into the building.
The cooling function can be easily switched of and the DCP can be used only to move the air within a building.
Desert cooler is suitable for installations in industrial plants and animal housing.
We recommend to have the equipment installed by competent personnel with knowledge about the climate
conditions of the given area.

OPERATION IN SAFE CONDITIONS
Warning
Follow the described transport instructions.
Do not remove the protective nets and guards.
In case the machine is equipped with protective nets for the panel (optional) we advise not to remove them.
Inform the maintenance personnel on the procedures and on the operative methods.
If the desert cooler operates in an environment where dust is present, this latter may obstruct the air
passages and find place on the fan blades, thus reducing the machine’s efficiency.
Part of the dust normally present in the air may be caught in the damp panel and deposit itself on the
bottom of the water tank. If the desert cooler is used in a dusty environment, a periodical cleansing of the
water tank should be effected.
The machine’s average life is ten years. Following this period a complete revision by specialized personnel is
mandatory.
Precautions
To avoid damages during transportation, the hydraulic system of the DCP is disassembled and the electric
panel is not hooked up.
- Do not start up the machine before having it properly fixed and having made the proper electric
connection in accordance to the current norms.
The DCP30 (Fig. 1) is not equipped with a fixed fan protection, since the desert cooler should be part of a
ventilation system. The machine should not be started unless it is hooked up to a proper system that
prevents access to the fan.
- Do not install the machine in places with risk of explosion as described by the CEI EN 60079 norm, and
do not treat materials that generate explosive dusts, as described by the same norm.
- The manufacturer is not responsible of damages to persons or objects caused by not having followed the
instructions contained in the present manual.
Residual risks
No residual risks are present.

CLIMATIC CONDITIONS TMIN / TMAX -25 / 55 °C
URMAX 95 % RH
(*) IN CASE OF SUSPECTED CONDENSATION FOLLOWING UNPACKING, KEEP THE MACHINE AT ROOM CONDITIONS FOR 24 HRS WITHOUT MAKING ANY
ELECTRICAL CONNECTIONS.
Installation DCP30 in raised position
The DCP30 comes with a base for ground positioning.
In the case that it is necessary to raise the vent position, to distribute the flow at a higher elevation, the
machinery may be placed on a stand or on a base.
In every case it is necessary to assure the solidity of the base to avoid its fall.
Installation DCP30 Top4
The desert cooler is positioned in the ideal place for its use, the shop’s floor. Important: the floor should be
strong enough to hold the weight of the DCP30. In the other case it is necessary to make a fixed support (e.g.
a cement floor) or a movable support (e.g. a sheet metal or board floor) able to meet the conditions of stability
required for the use of the machine, which are fundamental for safety.

Sheath assembly
The perforated sheath for the distribution of fresh air is made with special additives to resist ultraviolet rays
and has a very high mechanical resistance; nonetheless, if it is not mounted properly, it can deteriorate in just
a short time. The sheath must follow a perfect
straight line; any curve, even small, creates a
fold which, with time and stress, may give
origin to a tear.
ELECTRICAL SYSTEM
Electrical system layout
The electrical system layout is found in Attachment 1
Panel composition
The electrical panel is made up of:
1) 1 magnetothermal switch (motor saving) to protect the fan’s electric motor.
2) 1 magnetothermal switch (motor saving) to protect the water pump.
3) 1 contactor for activating the fan’s electric motor.
4) 1 contactor for activating the water pump.
All the components have been hooked up by the manufacturer. The installer must connect the electric motor,
the water pump and eventual environment thermostats (not supplied with the standard equipment) terminals
to the electrical panel.

Usage
1. CONDITION OF USE: All desert coolers may be installed in operating environments where there
are no people under 14 years of age.
2. RISKS DUE TO MOVING PARTS: the desert-cooler DCP30 comes without the fixed protection
in front of the fan, since it should be hooked up to a ventilation system in such a way to render
access to the fan impossible. The DCP30 Top4 instead comes with an adequate protection to avoid
access to the fan blades.
3. START UP AND SHUT OFF:
4. START UP: the condition of start up corresponds to the start up condition of the machine
(command ON or I).
5. SHUT OFF: the condition of shut off corresponds to shutting off the machine (command OFF or
0).
6. SHUT OFF / EMERGENCY SHUT OFF: is obtained by shutting off the machine (command OFF
or 0).
7. MACHINE START UP: occurs with a command from the thermostat / humidity control, only in
START UP condition.
8. CLEANING: The cleaning of the machinery must be carried out with the general switch on the off
position (position OFF or 0). Eliminate eventual foreign parts from the fan blades and clean the
water tank. Do not use water jets to clean the fan, in order not to damage the electrical motor.
Maintenance
General considerations:
Qualified personnel:
Maintenance operations must be carried out exclusively by personnel with the qualification of:
- Mechanical operator or assembler, for the mechanical parts.
- Electrician, for the electrical system.
General considerations:
All maintenance operations must be carried out with the machine shut off:
- General switch on the off position.
- Fan completely stopped.
If to reach the hanging models ladders are used, they should be in norm with the current regulations.
The personnel must wear safety clothing in accordance to the local conditions:

Desert-cooler: DCP30; DCP30 Top4
17(96)
2006
HC/MIT/UgGB-0599-02/06
- anti crushing gloves.
- safety shoes.
Fixed protection check:
The fixed protections in front of the fan on model DCP30 Top4 are designed in such a way that they cannot be
removed without using a special tool and they are fixed with screw that have a device that prevents their
removal.
The following are foreseen as causes of deterioration:
loss of screws and of fixing devices, impacts with forklifts, etc. In these cases the substitutions and the repairs
should be made in such a way as to ensure the original safety conditions.
The DCP30 must be installed in such a way that access to the fan blades is impossible without disassembling
part of the ventilation system with the proper tools.
Fan motor substitution
For the DCP30 model follow these steps:
•Verify that the machine is not hooked up to the power line.
•Disconnect the motor cable from the electric panel and keep the machinery without power for the
whole length of the operations.
•Remove the air vents in order to access to the fan.
•Remove the fastening nut from the hub on the axle of the motor and proceed to remove the whole hub-
fan block from the motor.
•Remove the fastening screw from the top, and then remove the top.
•Locate the motor supports and unfasten the four fastening bolts of the motor from their attachments.
•Remove the motor.
•During this phase be careful when moving the motor since it weighs 13 kg and should it fall it may cause
injury to the operator or anyone in the vicinity. Wear anti-crushing safety shoes.
•Invert this procedure to install the new motor.
For the DCP30 Top4 model follow these steps:
•Verify that the machine is not hooked up to the power line.
•Disconnect the motor cable from the electric panel and keep the machinery without power for the
whole length of the operations.

RESTARTING IN CASE OF SHUTOFF
Shutoff due to power failure on the line:
low danger
Cause: power failure.
Status following shut off: the DCP resets itself automatically.
Magnetothermal switch status check
NOTE: THIS OPERATION SHOULD BE EFFECTED BY PERSONNEL WITH THE QUALIFICATION OF ELECTRICIAN.
1) Open the electrical panel by untighening the 4 screws.
2) Verify that there is no electrical continuity between the corresponding terminals, up circuit or down
circuit from the magnetothermal switch. In that case that there is continuity, substitute the switch.
3) Close the panel.
MAINTENANCE AND CLEANING
A periodic maintenance of the water tank is necessary, especially if the DCP operates in very dusty environments.
As a good norm it is recommended to verify the machine’s conditions and to clean it once a year, during
the machine’s shut off period.
Tank and filter cleaning:
Follow this procedure:
1) Shut off the water intake faucet.
2) Point a jet of water (NON HYDRO CLEANING) towards the humidifying panels to remove the salt
and water deposits. If necessary use a medium bristle brush and a jet of compressed air.
3) Unscrew the plug from the “T” joint on the plastic tank.
4) Drain the water that is present. To facilitate the operation tilt slightly the machine in the direction of the
water flow.
5) Fill the tank with clean water and repeat the operation until the drained water is clean.
6) Remove the filter cartridge and clean it.
