5.2. OPERATION AND MAINTENANCE

● It is advised to carefully analyse all the operational and assembly guidelines listed in chapter 3 and 4.
● The casing of the device does not require maintenance.
● The heat exchanger should be cleaned on a regular basis from dust and fat deposit. It is especially recommended to clean the exchanger before the heating season with the use of compressed air
from the air intake side (after removing the inlet grid). You should pay special attention to the exchanger's lamellae which are very delicate.
● Should the lamellas be deformed (bent), straighten them with a special tool.
● The fan's motor does not require any exploitation service, the only service activities that may be necessary concern cleaning the air intakes from dust and fat deposit.
● Disconnect phase voltage, if the device is shut down for longer periods of time.
● The heat exchanger does not have any anti-freezing protections.
● It is recommended to provide a periodical purging of the heat exchanger, preferably using compressed air.
● Should the temperature in the room drop below 0°C, with a simultaneous drop of the heating medium temperature, there is a risk that the heat exchanger might freeze (crack).
● The level of air pollutants should meet the criteria allowable concentrations of pollutants in indoor air, for non-industrial areas, the level of dust concentration up to 0.3 g / m³.
● It is forbidden to use device for the duration of the construction works except for the start-up of the system.
● The equipment must be operated in rooms used throughout the year, and in which there is no condensation (large fluctuations in temperature, especially below the dew point of the moisture content).
The device should not be exposed to direct UV rays.
● The device should be operated at the supply water temperature up to 90 °C with working fan.

What to check
● Fitting of the heat exchanger terminals, using two keys acting in two opposite
directions (apply the keys on each terminal), which protects against the possibility
of internal breaking of the collecting pipes.
● Relation between the leaking and a potential mechanical damage to the
exchanger.
● Leaking of vent valve elements or drain plug.
● Parameters of the heating medium (pressure and temperature) should not
exceed the permissible values.
● Correctness of the draining of the exchanger.
● type of agent (it cannot be any aggressive substance Al or Cu active),
● Circumstances in which leaking occurred (e.g. during the trial/initial start-up of
the system; after having drained the heating medium, followed by the filling of
the system) and the external ambient temperature at the moment of the defect
taking place (freezing hazard to the exchanger).
● Potentially aggressive atmosphere (air) in the place of work (e.g. high
concentration of ammonia in the sewage-treatment plant).
● Installation of the device, according to the guidelines in the Operation and
Maintenance Documentation (among others, the distance from the ceiling).
● Correctness of the horizontal alignment of the device.
● Correctness of electrical connections and qualifications of
● Parameters of the supply current (among others: voltage, frequency).
● Incorrect covering of the curtain in the suspended ceiling.
● Noise in lower speeds (damaged winding).
● Noise present only in the higher speeds – blocking of the air outlet.
● Type of other equipment working in the facility (e.g. exhaust fans) – increasing
noise may be a result of several pieces of equipment working simultaneously.
● Correctness and quality of electrical connections and qualifications of the fitter.
● Parameters of the supply current (among others: voltage, frequency) on the
terminal block of the fan's engine.
● Operational correctness of other pieces of equipment present in the facility.
● Correct fitting of the conduits on the engine side – information available from VTS
Service Department.
● Voltage on the PE conductor (if present, it may indicate a breakdown).
● Damage, incorrect connecting or fitting of a wall-mounted controller, other than the
WING/VOLCANO or HMI-WING EC controllers
● Circumstances in which the defect occurred: remarks on the bill of lading,
inventory issue, condition of cardboard).
● Correctness and quality of electrical connections (tight clamping of conductorsin
electric terminals, cross-section and material of electric conductors) and the
qualifications of the fitter.
● Parameters of the supply current (among others: voltage, frequency).
● Operational correctness of the WING device, when connected directly to the
power supply (ignoring the controller).
● Whether the user has not damaged the "hand-wheel", e.g. by rotating it by 360˚,or
the switch, e.g. by keeping it in the intermediate position.
● Correctness of electrical connections and qualifications of the fitter.
● Operational correctness of the thermostat (the characteristic "ticking" when
switching the device).
● Parameters of the supply current (among others: voltage).
● Correctness of electrical connections and qualifications of the fitter.
● Operational correctness of the thermostat (the characteristic "ticking" when
switching the device).
● Operational correctness of the actuator.
● Parameters of the supply current (among others: voltage).
● Place of thermostat/actuator installation in the room.
WING 100-200
● Pay particular attention to the possibility of the freezing of the heat
exchanger in the winter. 99% of leaks occur during start-up/pressure
checks. The rectifying of the defect consists in the pulling back of the
vent/drain valve.
● Minimum distance: 10 cm from the ceiling
● Louder operation of WING devices may be a result of inappropriate place
of assembly: e.g. choking the fan or the acoustic specifics of a room.
● The electrical connection of the device must be carried out, according to
the diagrams found in the Operation and Maintenance Documentation.
● It is recommended to check the device by means of connecting the curtain
directly to the power supply and forcing the electric motor's operation
by shorting appropriate clips of the device's terminal strip and then the
terminal strip in the controller.
● Should the casing be defective, it is required to present photos of the
cardboard and device, as well as photos that confirm the compliance
between the serial number on the device and cardboard. If the damage
was done in transport, it is necessary to prepare a proper statement by the
driver/forwarder that delivered the goods.
● It is recommended to check the device by means of connecting the curtain
directly to the power supply and forcing the electric motor's operation
by shorting appropriate clips of the device's terminal strip and then the
terminal strip in the controller.
● The most important step is to check whether the actuator has reacted to
the electrical impulse within 11 s. When actuator damage is claimed, a
complaint must be submitted for the damaged element, and the actuator
must be deinstalled from the valve to open the valve mechanically
(permanently).
● If the "ticking" sound is not heard, the thermostat has been mechanically
damaged and should be subject to the complaint procedure. The
thermostat can also be installed in an improper space, which is subject to
temperature monitoring.
