6. Preventing the equipment from freezing
The heater is equipped with a freeze protection thermostat to prevent the equipment from
freezing.
When the discharge air temperature goes below +4 °C the thermostat stops the fan
(thermostat value should not be changed). The low temp sensor is situated inside the heater
on suction side.
NOTE!
At times the low twmp thermostat may prevent the fan from working normally. This may
happen for instance when the heater is taken into use straight from a cold warehouse etc.
when the sensor is not warm enough. To warm up the sensor you may use just fingers and
the fan will start after a while.
Warning!
−
The heater does not empty water throughout by itself. To empty the heat
exchanger totally from water it is necessary to use compressed air.
−
In freezing conditions make sure that the water cell is empty. If it is not
possible to empty the cell mix antifreeze with the water.
−
Warranty is void in cases where the cell is frozen!
7. Electric connection
Neglecting proper user manuals and electrical diagrams or changing them may cause
malfunctions and other consequences. In these cases the warranty is void.
Connecting the equipment
The heater is connected to electric power supply (400/230 V / 3N~ / 50Hz / 16 A) using a 16
A electric plug. Plug is equipped with a phase turning switch (to enable turning the rotation
direction of the fan).
The equipment is equipped with a control box containing all necessary electric couplings
(see 12. Electrical diagram). The fan shuts off only when the switch is turned to the “stop”
position.
The heater also contains an hour counter that measures the operating time of the fan.
8. Implementation
Before first use:
•
make sure that all couplings are appropriate
•
check the safety distances around the equipment
•
cabling should be made according to existing regulations
•
make sure the air intake filter is clean
•
make sure that the discharge opening and sound absorber are free from any objects
•
make sure that the fan is rotating in the right direction
During first use:
•
check the balance of the fan blade
