The above sizes of curtains are available with three options of voltage supply: 1x240VAC, 3x240VAC, 3x480VAC
! Voltage supply 1x240VAC is available only for the curtains WING E100 240/1/60, all WING W and all WING C
! Caution
The following models of WING air curtains must be supplied using High-Leg Delta supplying
circuit:
• WING E100 480/3/60 Air Curtain
• WING E150 480/3/60 Air Curtain
• WING E200 480/3/60 Air Curtain
For these models, the L1-N voltage will must be 240 VAC.
The use of the WING air curtain enables the leaving of the room door open, regardless of weather conditions, thus providing a protective barrier. The curtain also enables a simultaneous keeping of
the required heating comfort inside the room/facility. T he modern design of the WING air curtain is a result of its wide range of application. The places in which it is possible to install the device include:
malls, office buildings, supermarkets, cinema complexes, as well as shops, store-rooms, manufacturing facilities or warehouse rooms. Please notice that the use of an air curtain not only provides a
protective barrier, but also it is an additional heat source in the room. APPLICATION: warehouse rooms, warehouses, sports facilities, supermarkets, religious buildings, hotels, clinics, pharmacies,
hospitals, office buildings, manufacturing facilities. PRIMARY ADVANTAGES: protection of climatic conditions in the room, reduction of heating/cooling costs, universal size, ability to work both in
vertical and horizontal position; simple, quick and intuitive assembly.
2.2. PRINCIPLE OF OPERATION
WING W100-200 - heating medium, for example hot heating water, returns
heat through a heat exchanger with a wide heat-exchange surface, thus
providing high heating output (13.6-160 MBH). A transverse fan (518-2590
CFM) sucks in the air in the room, and pumps it through the heat exchanger,
back into the room. The jet of warm air is directed downstream at high
velocity, thus providing an air barrier.
WING E100-200 - electric heaters (6.8-51.2 MBH) heat up, as a result of the
flowing of electric current, and return the heat to the air; the air is blown off
through the fan, which sucks in the air in the room. A jet of warm air is directed
downstream at high velocity, thus providing an air barrier.

1. HEAT EXCHANGER – WATER HEATER: Maximum parameters of the heating agent for the heat exchanger are: 200°F, 232 psi. The aluminum and copper construction consists of copper
pipes of the coil and aluminum lamellae. The connection manifold (¾” male thread) is situated in the upper part of the housing. An optimally selected water exchanger was adapted to work in
three positions: horizontally and vertically, with stub pipes facing upwards and downwards. Appropriate lead of hydraulic connections makes it possible for the curtain to be assembled directly by
the wall as close to the door frame as possible. The air curtain with a water heater generates power from 13.6 to 160 MBH.
ELECTRIC HEATER: each electrical curtain consists of 6 electrical heaters of 670W to 2,950W, depending on the size of the curtain. The heaters are connected into two sections of 2 and 4 kW for
a 42in curtain, 4 and 8 kW for a 62in curtain, and 6 and 9kW for an 82in curtain. The heating section is connected to form a 1x230V or 3x230V, 3x480V power supply star depend on the chosen
device. Thanks to such technical solutions and the application of a wall-mounted controller, the heater of each curtain can work in two heating programs, e.g. for a WING E100 curtain - option
1): heating program 1 - 2kW, heating program 2 - 4kW, option 2): program 1 - 4kW, program 2 - 6kW, and analogously for the remaining curtain sizes. Change of program is displayed on the
diagram and consists in a cable switch in controller HMI. The heating program is independent from the fan speed setting.
Electric heater are protected with 4 thermostats, 2 for each section: one with automatic reset and second with manual reset. The thermostat button for manual reset is available to push from
the top of the curtain via the top cover grid on the motor side.
2. CONTROL SYSTEM: it is equipped with an outlet on the connection clamp block X1 for WING W100-200 and on the X2 block for WING E100-200 for connecting an on-wall controller as well as
a valve actuator for WING W100-200. WING air curtains can be additionally equipped with a wall-mounted DX controller. The DX controller has a three-position heating switch. In the case of a
water curtain, to guarantee the proper functioning of the water valve, the heating switch must be set to position II (central) - otherwise the valve will not open.
The system of WING E100-200 is equipped with a safety device in the form of a fuse in the 115 V AC circuit.
3. HORIZONTAL FAN: the maximum temperature of operation is 200°F; the rated voltage is 240 V/60Hz. The motor protection level is IP44. The horizontal fan applied in the device with an advanced
profile of blades and impeller geometry made of plastic makes it possible to obtain air capacities up to 2648 CFM. The control of the electric motor as well as thermal protections of the winding has
been coupled with the control system which resulted in increasing safety of operation. Due to optimum power of the motor the WING curtain is energy saving and durable.
5. INSTALLATION BRACKETS: WING is characterized by simple, quick and aesthetic assembly that can be performed on a wall in both horizontal and vertical position. There are from 2
to 3 installation handles attached (as an option) to the curtain (depending on the option (length). Connections of electric wires and water channels have been especially designed not to
interfere with the general aesthetic values of the device. The name WING includes devices that are 42, 62 and 82in long that, if necessary, can be additionally joined both horizontally
and vertically to achieve different air supply options: from the left to the right and the opposite. The reach of the air stream is up to 13 ft.

3. MOUNTING
IMPORTANT!
● The place of assembly should be carefully selected, taking into account the occurring of potential loads or vibrations.
● Prior to all installation or maintenance work, disconnect power supply and secure it against unintentional reactivation.
● It is recommended to use filters in the hydraulic system. It is recommended to clean/rinse the system, draining a few liters of water, prior to the connecting of hydraulic conduits (the supply
conduits, in particular).
IMPORTANT!
The air is blown out of the curtain at high velocity, along the surface of the opening, thus creating a protective barrier. Air curtains should cover the entire width of the door opening, in order to
obtain the maximum performance of the curtain.
IT IS RECOMMENDED TO TAKE INTO ACCOUNT THE FOLLOWING PARAMETERS, WHEN ASSEMBLING THE CURTAIN:
The width of the door frame should be less or equal to the width of the supplied air stream.

The range of the air jet - installation height
- Horizontal installation - Vertical installation
CAUTION! Air curtains with electric heat (models E100, E150 and E200) are not intended for vertical installation.
IMPORTANT! The heating output should be adjusted to the temperature inside the room, as well as the strength and direction of the wind outside. The primary criterion for the regulation of the
heating power is the temperature inside the room, near the door. Should a room thermostat be used, WING activates the heating mode, depending on the temperature settings.
IMPORTANT! Please consider additional factors that affect device operation.

3.2.1. HORIZONTAL INSTALLATION BY MEANS OF BRACKETS.
It is possible to install the WING do the wall horizontally in two options:
OPTION I: installation brackets with their arms faced upwards. In this option you should first screw the installation brackets to the wall (1) with intervals W1 for a 42in curtain (there are 2 installation
handles) and W1, W2 for 62in and 82in curtain (there are 3 installation handles) so that the handles' arms are levelled. Then lift the curtain and assembly with using screws (2) 1/4-UNC x 3/4 and plain
washers (3). Tighten the screws (2) and close the handle's covers (4).
OPTION II: Installation brackets with their arms faced downwards.
Installation consists in screwing brackets to the curtain (1). To mount the brackets to the curtain, with the housing upside down, punch holes (5) from the outside in the shields (4) using a hammer and a
screw. Click the shields on the brackets (1). Mount the brackets on the curtain using 1/4-UNC x 3/4 screws (2) and washers (3). This installation option allows for mounting brackets to the curtain first,
and then screwing the entire housing to the wall.
Caution!
For any of above listed installation
method, the minimum distance between
the unit and the ceiling/side walls -
minimum 4 inches.

3.2.2. VERTICAL INSTALLATION USING INSTALLATION BRACKETS.
It is possible to install WING to a wall vertically on both sides of the gate (with the motor on the bottom or on the top).
For this option it is not important if you screw the handles down to the unit first and then screw the whole down to the wall or first attach the handles to the wall and then screw the curtain down to the
handles.
To install the curtain vertically, use 1/4-UNC x 2 3/4 (outside the scope of VTS delivery) screws. Screw 2 or 3 brackets using the screws, passing through flat washers (3), to the threaded sleeves mounted
in the upper part of the housing.
IMPORTANT: For vertical installation, keep minimum distance of 4 inches between the floor and the lower end of the curtain. This is to secure free access to the water coil air vent.
E
IMPORTANT! The device is intended for the operation in dry rooms, exclusively. Thus, pay particular attention to the condensation of wat er vapor on engine elements, since it is not fitted
for operating in humid environment.
IMPORTANT! The WING air curtains are not intended for the installation:
● Outdoor.
● In humid rooms;
● In rooms categorized as explosive environments.
● In rooms with very high levels of dustiness;
● In rooms with aggressive atmosphere (due to the presence of copper and aluminum structural elements in the heat exchanger and electric heaters).
IMPORTANT! The WING EH air curtains are not intended for the installation on suspended ceilings.
3.3. INSTALLATION GUIDELINES
CONNECTION OF THE HEATING MEDIUM
When connecting the air curtain to the heating water pipeline, secure the coil headers from excessive torque using set of two keys. The weight of installed pipelines should not impose a load on
the heater’s headers.
IMPORTANT! Pay particular attention to the leak-tightness of connections, when filing the hydraulic system. Make sure that the water flowing from a leaky connection does not leak to the
electric engine (at the vertical installation)
IMPORTANT! It is recommended to use filters in the hydraulic system. It is recommended to clean/rinse the system, draining a few liters of water, prior to the connecting of hydraulic conduits
(the supply conduits, in particular).

Air curtains control
• The motor is controlled by applying voltages in the range 0-10VDC to terminals Ai and G
• The motor will not start when a voltage of 0-1VDC is applied to terminals Ai and G
• The motor speed is controlled by changing the voltage supply to the terminals Ai and G in the range 1-10VDC. The value of the given voltage in a linear manner influences the motor speed in the
range from 10-100% of its full efficiency.
• The electric heating coils should only be turned ON when the motor is running at least 45% of its full capacity. Starting electric heating coils when the motor is switched OFF can be dangerous and
can lead to damage to the device.
• Electric heating coils are divided into two independent sections controlled by applying 240VAC to terminals 2 and 3 on the terminals of electric curtains
EN
IMPORTANT!
• It is recommended to connect wires to the terminal strip with previously clamped appropriate clip ends.
• Make sure that the space around the place where the air is sucked in by the curtains, as well as around the exhaust grid, is free of any structural elements of the building, which might hamper the
flow of air (e.g. suspended ceilings, covering development, ventilating ducts etc.).

● All protective equipment is to be installed before the pressure increases, according to maximum the permissible pressure rating of 232 psi.
● Hydraulic connection should be free of any stresses and loads.
● Check the correctness of hydraulic connections (leak-tightness of the vent, collecting pipes, correctness of fittings installation), prior to the initial start-up of the device.
● It is recommended to check the correctness of electrical connections (of automatics, power supply), prior to the initial start-up of the device. It is advised to use an additional, external residual-
current protection.
IMPORTANT! All connections should be carried out, according to this technical documentation and the documentation delivered with automation equipment.
5.2. OPERATION AND MAINTENANCE
● It is advised to carefully analyze all the operational and installation 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 32°F, 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 1.87x10-5 lbs/ft3.
● 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 200 °F with working fan.

6.1. PROCEDURE IN CASE OF MALFUNCTION
EN
It is forbidden to place, dispose of and store worn-out electric and electronic equipment, together with other waste. Dangerous compound contained in electronic
and electric equipment have a very adverse impact on plants, micro-organisms, and, most importantly, on humans, as they damage our central and peripheral
nervous system, as well as circulatory and internal system. Additionally, they cause serious allergic reactions. Worn-out equipment is to be delivered to a local
collection point for used electric equipment, which carries out a selective collection of waste.
REMEMBER!
The user of equipment intended for households, and which has been worn out, is obliged to transfer such equipment to a collecting unit that collects worn-out
electric and electronic equipment. The selective collecting and further processing of waste from households contributes to the protection of environment,
reduces the penetration of hazardous substances into the atmosphere and surface waters.
6.2. COMPLAINT PROCEDURE

7. INDUSTRIAL SAFETY INSTRUCTION
Special instructions concerning safety
IMPORTANT!
● Prior to the commencing of any work related to the device, it is required to disconnect the system, secure it properly and wait, until the fan stops revolving.
● Use stable working platforms and hoists.
● Depending on the temperature of the heating medium, pipes, elements of casing and surfaces of the heat exchanger can be very hot, even after the fan has stopped revolving.
● Sharp edges may be present! Wear gloves, protective shoes and clothing, when transporting the device.
● Strictly observe safety guidelines and industrial safety regulations.
● Loads can be placed only in the previously selected areas on the transporting unit. Protect the edges of the device, when lifting it, using a set of machines. Remember to distribute weight evenly.
● The equipment must be protected against moisture and dirt, and kept in rooms protected against the impact of weather conditions.
● Utilization of waste: make sure that operating and auxiliary materials, including packaging material and spare parts, are disposed of in a safe, environment friendly manner, according to the binding,
local statutory regulations.
Leakage in the WING
W100-200 heat
exchanger
● 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).
● 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.
