Installation and Operation
General Instructions
Read these instructions carefully before installation and use. Keep this manual for future reference. The product must only be used as described in the assembly and operating instructions. The guarantee is valid only if the product is used as intended and in accordance with the instructions.
Operation
The air curtain draws air from the top and blows it downwards, creating a protective barrier. For optimal effect, the unit should match the door opening width. The outlet grille is adjustable and typically angled outwards.
Air curtain efficiency is influenced by air temperature, pressure difference across the doorway, and wind load. Negative pressure within a building significantly reduces efficiency; ventilation should be balanced.
Start-up
Upon first use or after a long period of inactivity, dust or dirt on the heating element may cause smoke or odor, which is normal and temporary.
Connecting the Water Coil (W)
Installation must be performed by an authorized installer. The water coil is suitable for closed water heating systems and must not be connected to mains pressure or open water systems. A regulating valve (Frico valve kit) is recommended. Connections are via steel pipes with DN20 (3/4") terminals. Flexible hoses are available as accessories. Shut-off valves are required for the heating coil connections for easy removal. A drain valve is included; a vent valve should be connected at a high point. Use pipe wrenches carefully to avoid straining connections and causing leaks.
Filter (W)
An internal air filter protects the water coil. For environments requiring frequent cleaning, an external intake filter (see accessories) is recommended for easier maintenance, allowing the unit to remain closed.
Electrical Installation
Installation requires an isolator switch with at least 3 mm (0.12 in) contact separation and must be performed by a qualified electrician according to local wiring regulations. The control system is pre-installed.
- Unit without heating or with water heating: Connected via a built-in control board with a 1.5 m (4.9 ft) cord.
- Unit with electrical heating: Electrical connection is on the unit's top. Power supply for heat and control (208V3~/480V3~/600V3~) connects to a terminal block in the primary terminal box. 480V3~/600V3~ supply is transformed to 230V~ via an internal transformer and routed through 2x 10A fuses. 208V3~ supply is connected internally through 2x 10A fuses. The largest cable diameter for the terminal block is AWG6. Cable glands must meet protection class requirements. Indicate in the distribution board that "air curtains can be supplied from more than one connection".
Refer to wiring diagrams for detailed connections.
Control Options
Stepless Airflow Control with Door Contact/Position Limit Switch
When the door is closed, the fan runs at low speed. When the door opens, the fan runs at high speed, controlled remotely or via the gable end control panel. This provides low response time and optimal protection.
Control Panel and Remote Control
The air curtain has an integrated control system and can be remotely controlled. The control panel allows adjustment of fan speed (1/2/3), heat step (half/full power for electric, on/off for water), and on/off functions. The remote control offers similar functionality.
Dip-Switch Settings
Dip-switches are used for factory settings, controlling functions like 0-10V, HEAT, ALARM, and WATER. Dip-switch 3 is used for PA2DR.
Functional Test
A functional test can be initiated using the remote control by pushing specific buttons within 5 seconds. Fan and heating steps are tested in 10-second intervals. All LEDs flash upon completion.
Temperature Control
If the temperature exceeds 50 °C, the fan runs at full speed for 2 minutes to dissipate heat. If the temperature rises above 50 °C again within 5 minutes, an overheating alarm is triggered, indicated by flashing red LEDs and locked buttons. To resolve, disconnect power, identify and rectify the cause, then reconnect the unit.
Maintenance
Unit with Water Heating
The appliance filter should be cleaned regularly for optimal air curtain effect and heat emission. Frequency depends on local conditions. A clogged filter does not pose a risk but can impair function. Cleaning involves disconnecting power, removing the front hatch, and vacuum cleaning or washing the filter. Replace if clogged or damaged.
All Units
Fan motors and other components are maintenance-free. Regular cleaning is recommended (at least twice a year). Inlet/exhaust grilles, impellers, and elements can be vacuumed or wiped with a damp cloth. Use a brush for vacuuming to protect sensitive parts. Avoid strong alkaline or acidic cleaning agents.
Overheating
Units with electrical heating have overheat protection. If deployed, disconnect power, determine and rectify the cause, remove the front hatch, press the red reset button inside the terminal box, reattach the hatch, and reconnect power. Motors have an integral thermal safety cut-out that stops the unit if the motor temperature is too high, resetting automatically when the temperature returns to normal limits.
Service, Repairs, and Troubleshooting
Service, Repairs, and Maintenance
Before any service or repair, disconnect the power supply. Remove the front hatch by unscrewing the top and detaching the bottom bent edge (Fig. 3). After service, reattach the hatch securely. Note that removing the end may also detach the outlet grille.
Replacing Motor or Impeller
Steps include removing the front, gable end, disconnecting motor cables, removing screws, and lifting out the motor and impeller. Installation is the reverse.
Replacing Heating Elements/Heating Package (E)
Mark and disconnect cables, remove mounting screws, lift out the heating elements/package, and install the new ones in reverse order.
Replacing the Water Coil (W)
Shut off water supply, disconnect connections, detach plastic ends, detach intake grille (by drilling out rivets), remove mounting screws, and lift out the coil. Install the new coil in reverse order.
Draining the Water Coil (W)
The drain valve is located on the underside of the coil on the connector side and is accessible via the front hatch.
Troubleshooting
If fans are not running or performing properly: Check built-in control system functions/settings and ensure the intake grille/filter is not dirty.
If there is no heat: Check built-in control system functions, internal sensor, and settings. For units with electrical heating, also check power supply, fuses, circuit-breaker, and overheat protection. For units with a water coil, ensure the coil is air-free, has sufficient water flow/pressure, and incoming water is adequately heated.
If faults cannot be rectified, contact a qualified service technician.
Safety Instructions
Read safety instructions before installation and maintenance. Installation and maintenance should only be performed by qualified technical staff.
- Do not install or use outdoors or in aggressive/potentially explosive environments. Ensure the site's environment does not require a higher IP classification than stated on the unit's data label.
- Connect the unit in accordance with local requirements. Ensure the power supply voltage matches the local mains voltage. Voltage and maximum ratings are on the unit's data label.
- Fuse the unit according to the provided table.
- For electrically heated products, use a 300 mA residual current circuit breaker for fire protection.
- Keep areas around air intake and exhaust grilles clear of obstructions.
- Do not cover the unit fully or partially, as this can cause overheating and fire risk.
- Use lifting equipment to lift the unit.
- Child Safety: This appliance can be used by children aged 8+ and persons with reduced capabilities if supervised and instructed on safe use. Children shall not play with the appliance. Cleaning and maintenance by children require supervision. Children under 3 years must be kept away unless supervised. Children aged 3-8 years can only operate the unit if placed in its intended position and supervised, understanding the hazards. They must not plug in, regulate, clean, or perform user maintenance.
- Caution: Some parts can become very hot and cause burns. Special attention is needed where children and vulnerable people are present.
Residual Current Circuit Breaker (E)
If a residual current circuit breaker trips upon connection, it may be due to moisture in the heating element, especially after periods of non-use or storage in damp environments. This is not a fault. Rectify by connecting the appliance to the main supply via a socket without a safety cut-out to dry the element. This may take hours to days. Periodically run the unit briefly when not in use to prevent this.
