TRANSPORTATION AND STORAGE RULES

Transport the product by any transportation vehicle in the manufacturer's original package.
Store the delivered product in the manufacturer's original packing box in a dry ventilated premise with
the temperature range from +5ºC up to + 40ºC and relative humidity less than 80%.
The storage environment must not contain dust, acid or alkali vapours that may cause corrosion of the
product parts.
ELETRONICS CONTROL LOGIC
VKMI U fan (fig. 17) is equipped with the electronic module TSC (speed controller with electronic
thermostat) for automatic fan speed (air capacity) control depending on air temperature.
The terminal block module has two control knobs:
- for setting the motor speed;
- for setting electronic thermostat threshold.
The light indicator on the front panel shows thermostat operation.
Set the desired thermostat temperature (operating threshold) by turning the thermostat control knob
clockwise to increase and counter clockwise to decrease the setpoint.
Set the desired impeller speed (air flow) by turning the impeller speed control knob in the same way.
The control logic has temperature and timer-dependent patterns.
Temperature pattern (VKMI U):
Is used to keep air temperature to within 2ºC. The speed switches are rare.
As air temperature rises beyond the set temperature controller threshold, the fan is switched to maximum
speed.
As air temperature falls 2ºC below the set temperature threshold or if the initial temperature is below the
set threshold, the fan runs with pre-set speed.
Timer pattern (VKMI U1):
Is used for exact maintaining of air temperature. The speed switches are more frequent as compared
to the temperature sensor mode but in any case the switching cycle does not exceed 5 minutes.
As air temperature rises beyond the set temperature controller threshold, the fan is switched to maximum
speed.
As air temperature falls below the set temperature threshold, the fan switches to the pre-set speed
5 minutes after timer countdown.
If the initial temperature was below the set threshold, the fan runs with pre-set speed.
