! 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.

INCORRECT

CORRECT

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.

Factors that have a negative effect on curtain operation

Factors that have a positive effect on curtain operation

doors or windows that are constantly open in the room, thus creating a draft

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.

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).
