R6 Model :
1 - Remote control IR receiver (remote not included)
2 - Low water signal lamp / fill up (yellow)
3 - Water injection on signal lamp (green)
4 - Fan on signal lamp (Red)
5 - Fan On/Off
6 - Water injection On/Off
7 - Dome light On/Off
8 - Change fan speed (5 fan speeds)
• TURNING THE ROOF AIR COOLER ON/OFF: To turn the roof air
cooler on, press button 5 on the control panel. To turn the roof air
cooler off, press button 5.
• FAN SPEED: R6 control panel has 5 speeds controlled by button
8. Pressing multiple times cycles between low, medium and high
speeds. The fan is factory set to start at the minimum speed when
pressing the button 8.
• WATER FUNCTION: To turn on/o the water function (ventilation
with water cooling process) press button 6. The green led 3will light
showing the water function is on. If the green led 3 is continuously
on, it means that the water function is in operation, but the injection
pump is not working. Green led 3 blinking means that water function
is operating and the injection pump is working too.
Note: When the fan starts, water function starts working
automatically.

• FAN: Located in the center of the base, it is responsible for the
ventilation, getting the air from outside and carrying it to inside of the
cabin, already cooled. Its carbon brushes must be inspected every six
months and, if necessary, replaced. It is suggested to change the fan
every two years.
3. Maintenance Items
• STRAW FILTER SET: Located inside the water tank, it lters dirt, dust
and insects. It humidies the air coming from outside, through an
evaporation process where the air, passing through the straw lter, joins
the water and an exchange of heat occurs. The lter has a water tubing
(hose) that spreads the water sent by the pump. Take out the straw and
clean the water exit holes with a needle to remove obstructions. Pass an
air blast in the holes and put the lter back in the water tank.
Note: It is suggested the cleaning of the straw lter be done every
two months and the straw rell replaced every six months. This
cleaning or exchange may vary according to the severity of the roof
air cooler’s application.
• LACK OF WATER: The control panel has a sensor to detect lack of
water inside the tank. When the water level is lower than minimum,
the yellow led 2 starts blinking, informing the user needs to rell
the water tank. After lling it, the water function will automatically
be activated.
Note: When lack of water is detected, water function stops
automatically.

A periodical maintenance is essential for the best
performance of your Fresair roof air cooler.
• INTERNAL BASE FILTER: Located in the base, it is responsible for
ltering the water excess that decants from the straw lter. The
water is recycled and sent back to the water tank totally clean. That’s
why it is essential to keep it always clean.
Procedure: At least, every two months, apply an air blast through
the tissue or wash it, since if there is too much dirt in the lter, it will
stop the passage of the water, leading to a possible leakage.
Note: In case of most severe application of the roof air cooler, with
high accumulation of dirt, cleaning should be performed more often.
• WATER PUMP:
- INJECTION: Located in the water tank, it sends the water to the
straw lter set.
- RETURNING: Located in the base, it sends the excess of water back
to the water tank.
Note: Take out the pumps every two months and clean them with
air blast. It is recommended to replace them every six months.

8
• BASE PREFILTER: Located at the base, it is responsible for second
ltering process, avoiding the entrance of dirt into the pump. It
avoids clogging and the breakdown of the pump.
Procedure: At least every two months apply some air blast and/or
wash it. Accumulation of dirt interrupts the passage of water, what
can cause water spilling.
Note: In case of most severe application of the roof air cooler, with
high accumulation of dirt, cleaning should be performed more often.
A periodical maintenance is essential for the best
performance of your Fresair roof air cooler.
• WATER LEVEL SENSOR (BUOY): Responsible for controlling water
level inside the tank, indicating lack of water.
• CHECK VALVE: Anti-return or check valves are used to allow free
ow in one direction and block ow in the opposite direction.
Note 01: If the check valve is replaced, observe the mounting
direction. The arrows MUST be directed towards the return pump
to the tank.
Note 02: The removal of the check valve will cause accumulation
of water in the base and water may leak into the outside of the
vehicle.

Control Panel R6
• CONTROL PANEL R6: It controls all equipment functions. It doesn’t
have a xed useful life since this depends on the handling and
periodical revisions. This product is equipped with an internal safety
circuit against fan and pumps short-circuits. In case your roof air
cooler stops working, always check the fan and pumps rst, since
the defect could not be on the control panel. The control panel
may have turned o, protecting itself against some other electrical
defects. Check also the general fuse in the battery.

6. Remarks
Note 1: If the roof air cooler keeps o for a long period, you can feel
some slight unpleasant smell when you turn it on again, as a result of
features of its straw lter. After a few continuous cycles this smell stops
(it varies according to air humidity and environment temperature).
Note 2: This model has exclusive application for on road uses. We do
not recommend o road uses.
ATTENTION: Never add softener, essences, perfumes or similar to
water in the tank. These products make foam, what may cause leak
allowing water to enter into the cab. Keep the container always clean
and with pure water.
