Switching on:
Set power on / off switch
12
into the "ON" position
(see fig. 7.1).
Switching off:
Set power on / off switch
12
into the "OFF" position
(see fig. 7.2).
[CT36075, CT36076]
Before connecting the appliance to the mains,
make sure that on / off switch 12 is in the down
position "OFF" (see fig. 8.2).
Switching on:
Move on / off switch
12
upwards (see fig. 8.1).
Switching off:
Move on / off switch
12
downwards (see fig. 8.2).
Design features of the appliance
Oil-free air compressors
Oil-free air compressors do not require oil changes,
and piston sliding is achieved by using materials with
a low coefficient of friction. It makes easier their us
-
ing, and the received compressed air does not contain
oil impurities� Also these compressors has light weight
and lower price, which is an ideal choice for the home
workshop�
Automatic switching on / off
After switching on, the appliance operates in a cy-
clic mode: pressure relay
13
maintains the constant
pressure value in receiver
4
, switching on / off the
appliance depending on the consumption of com-
pressed air by connected pneumatic tools� When
the appliance is being switched on, the air is sucked
through air filter (filters)
10
and injected into receiv-
er
4
through piping
11
� When the maximum pressure
value (the value of this parameter is set at the fac-
tory) is reached, pressure relay
13
is activated and
the electric motor is switched off� Excess air from
piping
11
and cylinder is discharged through the
valve� Thus, there is no excess pressure in cylinder
(cylinders) and piping
11
- this reduces the load on
the electric motor the next time when the appliance
is started� If pressure inside receiver
4
drops to the
minimum value, the electric motor starts up and the
appliance starts pumping air into receiver
4
until it
reaches the maximum value� The appliance operates
in this mode as long as on / off switch
12
is in the
position "ON"�
If the appliance does not switch off automatically when
the maximum pressure is reached, then the excess
pressure is discharged through safety valve
16
� In this
case it is necessary to immediately contact a dedicat-
ed
CROWN
repair workshop�
Temperature protection
Temperature protection prevents from damage to the
appliance, switching it off during excessive loads and
overheating� For example, when using pneumatic
tools whose air consumption exceeds the appliance
capacity, or when filter element (elements)
36
is
clogged, etc� This protects the electric motor against
overload�
When temperature protection is activated button
6
snap
off and appliance switched off� In this case, unplug the
appliance from the mains, eliminate the cause that trig-
gered the protection, allow the appliance to cool down,
press and release button
6
, switch on the appliance (as
described above) and then continue working�
Pressure adjustment (see fig. 7-8)
Pressure regulator
14
allows you to adjust pressure of
compressed air in outlet fittings
17
, as may be required�
•
Manometer
18
shows the set pressure value�
The pressure value inside receiver
4
is shown by
manometer
19
�
•
To increase the pressure, rotate the handle of pressure
regulator
14
in the direction shown onto fig. 7.3, 8.3.
•
To reduce pressure, rotate the handle of pressure
regulator
14
in the direction shown onto fig. 7.3, 8.3.
Recommendations on the appliance op-
eration
Before starting work
•
It's recommended to install the appliance on a flat
horizontal surface, this reduces the risk of the appli-
ance turn-over during operation� However, it is allowed
to install the appliance on sloped surfaces, this does
not affect its performance in any way (but you must
first make sure that the appliance can not turn-over
during operation)�
•
Connect pneumatic tools to the appliance�
•
Connect the appliance to the mains�
•
Оpen the valve on outlet fitting
17
�
•
When carrying out works related to spraying
liquids, make sure that no drops of liquid get on the
appliance�
•
If you need to move the appliance during operation,
disconnect it from the mains and depressurize
receiver
4
, and then transport�
•
If case of any side sounds or strong vibrations on
the part of the appliance, immediately switch it off and
contact the
CROWN
service center�
General recommendations
•
Switch on the appliance�
•
Using pressure regulator
14
set the pressure
required for operation�
•
Do not overload the appliance� The operating mode
of the appliance is intermittent with the cyclic duration
factor of up to 55%, while the duration of a cycle
is 6-10 minutes� It is allowed to operate the device
continuously for 15 minutes, but not more often than
once within 1�5 hours�
After completing the operation
•
Switch off the appliance�
•
Disconnect the appliance from the mains�
•
Close the valve on outlet fitting
17
�
•
Disconnect pneumatic tools from the appliance�
•
To depressurize receiver
4
pull by the ring of safety
valve
16
or open the valve onto outlet fitting
17
(in case
when nothing is connected to the fitting
17
)�
•
Drain the condensate from receiver
4
, as described
below�
