Frico AD200A Original Instructions Manual page 23

*Commutable units can be used for 3x230V or 3x400V.
To convert the elements see wiring diagram on page 7.
Start-up
When the unit is used for the first time or after a long
period of disuse, smoke or odour may result from
dust or dirt that has collected on the element. This is
completely normal and disappears after a short time.
Trouble shooting
If the fans stand still, check the following:
a) Power supply; check fuses, circuit-breaker,
time switch (if any) that starts and stops
the unit.
b) That the air flow selector is correctly set.
c) That the position limit switch is working
(if any).
If the error cannot be fixed, please contact qualified
service technician.
If there is no heat, check the following:
a) Power supply to electric heater; check fuses and
circuit-breaker (if any).
b) Thermostat settings and actual temperature.
c) That the output selector (if any) is set correctly.
d) That the overheat protection has not been released.
Overheating
(applies to units with electric heat)
The Thermozone is equipped with an overheat protec-
tor. If it is released due to overheating, reset as follows:
1) Disconnect the electricity with the fully
isolated switch.
2) Investigate the matter and repair the fault.
3) Reset is performed as follows:
• Locate the red button which is located inside
the unit at the inner gable to which the fan and
the motor are attached. You can see it if you remove
the front plate, see page 2.
• Press the button until a click is heard
4) Connect the Thermozone again.
If the error cannot be fixed, please contact qualified
service technician.
Maintenance
NOTE! Disconnect electricity prior to cleaning or inspec-
tion (units with electric heat can be supplied from more
than one connection).
The fan motors and the other components require
no maintenance other than cleaning when necessary,
however at least once year.
Note! Units provided with aluminium heating ele-
ments shall be inspected and if necessery cleaned on a
reguarly basis. Grille, impeller and elements are vacuum
cleaned or dried clean with a damp cloth. Open the
inspection hatch to reach elements and impellers.
AD200A/E
Residual current circuit breaker
(applies to units with electric heater)
When the installation is protected by means of a
residual current circuit breaker, which trips when the
appliance is connected, this may be due to moisture in
the heating element. When an appliance containing a
heater element has not been used for a long period or
stored in a damp environment, moisture can enter the
element.
This should not be seen as a fault, but is simply rectified
by connecting the appliance to the mains supply via a
socket without a safety cut-out, so that the moisture can
be eliminated from the element. The drying time can
vary from a few hours to a few days. As a preventive
measure, the unit should occasionally be run for a short
time when it is not being used for extended periods of
time.
The garantee is only valid if the Thermozone
units are used in the manner intended by the
manufacturer and in accordance with the
installation and maintenance instructions.
Safety
• For all installations of electrically heated products
should a residual current circuit breaker 300 mA for fire
protection be used.
• Keep the areas around the air intake and exhaust gril-
les free from possible obstructions!
• During operation the surfaces of the unit can be hot!
• The unit must not be fully or partially covered with clo-
thing, or similar materials, as overheating can result in a
fire risk! (E)
• This appliance is not intended for use by persons (in-
cluding children) with reduced physical, sensory or men-
tal capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction
concerning use of the appliance by a person responsible
for their safety. Children should be supervised to ensure
that they do not play with the appliance.
