MOUNTING

The fan is designed for horizontal installation on the feet, fig. 2. The fan may be equipped (modification

VKMI XXX K) with a fixing bracket with vibration dampers (or delivered separately) to facilitate the fan

mounting in horizontal or vertical position to the floor, to the wall or to the ceiling, fig. 3.

If the fan is mounted outdoors it should be protected against the elements and moisture ingress, e.g. by

means of a top hood above the fan in case of vertical mounting and by 1 diameter air duct in case of

horizontal mounting. The outlet spigot must always be connected to air duct. The fan mounting sequence is

shown in fig. 4-10 and 11-16. Wiring diagram for a fan model without power cable and a plug is shown

in fig. 11.

MAINTENANCE

The product surfaces must be regularly (once in 6 months) cleaned from dirt and dust (fig. 19-21).

Disconnect the fan from power mains prior to any maintenance operations.

For cleaning use a soft cloth or brush and mild detergent water solution.

Avoid water dripping on the electric components (fig. 22).

Wipe the surfaces dry after cleaning.

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.

mepokerkft.hu

The fan VKMI P (fig. 18) is equipped with a speed controller that enables fan switching on and off, smooth

speed (air flow) control from minimum to maximum value.
