Thermozone AD300A/E, AD400A/E
Adjusting the air curtain and air stream
The direction and the velocity of the air stream
should be adjusted in regard to the load on the
doorway. Pressure forces the air stream to bend
towards the interior of the room (when the room is
heated and the exterior is cold).
The air stream should be directed outwards to resist
the pressure. An angle up to 15° is recommended.
THe more load caused by negative pressure,
temperature differences and wind, the more should
the air beam be directed outwards.
Basic air flow settings
The air flow is set with the air flow selector so that
the speed of the air is 3-4 m/s 1m above the floor.
The direction of the air beam and the air speed
may need to be adjusted more exactly depending
on the load on the door.

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
protector. 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
inspection (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. Grille,
impeller and elements are vacuum cleaned or
dried clean with a damp cloth. Open the
inspection hatch to reach elements and impellers.
Safety cut-out
(applies to units with electric heat)
If the installation is protected by means of a safety
cut-out, 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 and is 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 driven out of the element.
The drying time can vary from a few hours to a
few days. As a preventive measure the
Thermozone should occasionally be run for a short
time when it is not being used for an extended
period 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.
