Assembly and operating instructions

General Instructions

Read these instructions carefully before installation and use. Keep this manual for future reference.

The product may only be used as set out in the assembly and operating instructions. The guarantee is only valid if the product is used in the manner intended and in accordance with the instructions.

Application area and function

UF600 creates a very effective air barrier when air at high speed is pushed out through a narrow channel situated in the ﬂoor inside the door opening. An air barrier directed upwards from the ﬂoor gives the best possible protection against cold air ﬂowing into the premises. UF600 consists of a pillar with inlet hood, silencers and fans, as well as a ﬂoor channel with its slot at ﬂoor level. The pillar is placed outside (or inside) the door on either side of the opening. The ﬂoor channel is cast in ﬂoor. Its width is adapted to the speciﬁc door. Ambient Temperature limits: -20 °C –55 °C. Protection class: IP54.

Operation

The air is drawn in through the air inlet at the top of the unit and blown out through a narrow air outlet slot in the ﬂoor. The air is distributed at high velocity across the whole doorway, providing a protective air shield. The air shield minimises cold draughts and reduces heat loss through open doorways. The air outlet slot is angled outwards 15° to achieve the best protection. För bästa skydd är det lämpligt att ställa in olika öppningslägen för dörren för att inte behöva öppna den mer än nödvändigt. The efﬁciency of the air curtain depends on the air temperature, pressure differences across the doorway and any wind pressure.

NOTE! Negative pressure in the building considerably reduces the efﬁciency of the air curtain. The ventilation should therefore be balanced.

Mounting - see Appendix A

The UF600 unit is assembled according to this manual and bolted together with supplied bolt kit. The ﬂoor channel design choosen is cast into the ﬂoor complete with air outlet slot, inspection hatch and connection box. The air outlet slot should extend approximately 150 mm outside the door edges. The UF600 unit is connected to the connection box with the ﬂange shown in this manual, see ﬁg. 3. Pillar extension can be ordered as accessory. The UF600 unit should be fastened in ceiling or wall to avoid the risk of tipping if the unit is hit by a vehicle. UF600 should also be protected with collision protection.

If the air outlet slot is more than 300 mm away from the door opening the ﬂoor channel should be prolonged or side protection should be mounted on both sides of the door to increase air curtain effect. Standard max load on ﬂoor channel is 7 ton, up to 20 ton for special orders.

Electrical installation

The air curtain should only be wired by a competent electrician, and in accordance with the latest edition of IEE wiring regulations. The connection is via the terminal box ﬁtted on the outside of the fan housing. See wiring diagrams.

Service, repairs and maintenance

For all service, repair and maintenance ﬁrst disconnect the power supply.

The level of cleaning can vary depending on local conditions. Undertake cleaning at least twice a year. Periodically check the following according to ofﬁcial requirements, however at least once a year:

• Screw connections, speciﬁcally the rotor

ﬁtting.

• Is there dirt in the fan wheel? If so, remove

it.

• Have accumulations formed the rotor? If so,

remove them.

• Functions and settings of the control box

UFC600.

Page 14

• Operating current.

• The ﬂoor channel should regularly be cleaned through the inspection hatch.

NOTE! The power supply must always be disconnected before disassembling any part of the unit.

Overheating

All motors are equipped with an integral thermal safety cut-out. This will operate, stopping the air curtain should the motor temperature rise too high. The cut-out will automatically reset when the motor temperature has returned to within the motor’s operating limits.

Control box UFC600 is equipped with motor protection for each one of the fan motors. If there is an overload the motor protection will deploy, stopping the air curtain. The motor protection must be reset manually. If the motor protection is deployed, please check the fuses and if the air inlet is blocked.

Trouble shooting

If the fans are not working or do not blow properly, check the following:

• Operating power supply to the unit;

check fuses, circuit-breaker, time switch/ thermostat (if any) that starts and stops the unit.

• Functions and settings of the control box

UFC600.

• That the position limit switch is working.

• That the overheat protection for the motors

has not been deployed.

• That the intake grille/ﬁlter is not dirty.

• That the air outlet slot is not blocked.

If the fault cannot be rectiﬁed, please contact a qualiﬁed service technician.

Start-up current

The external fusing must be adapted to the motor start-up current.

Safety

- Do not cover surfaces of the air curtain or obstruct air inlet, as this can cause excessive temperatures that can be hazardous and may cause fan motor malfunction.

- Do not block the air outlet slot.

- The air velocity will be too high for people to go through the air ﬂow. People should not enter the opening without protection from a vehicle etc.

Control options

Control box UFC is available as accessory.

Accessories

UFC, control box

Y/D-start with time delay between the motors. Possibility to use with door switch or position limit switch or external on/off. Integrated motor protection for each fan. Alarm and running indication.

AGB304, position limit switch

Starts the air curtain when the door is opened and stops it when the door is closed. Alternating contact 4 A, 230 V~. IP44.

UFEH, pillar extension

For indoor mounting the air intake should be above the door opening, therefore an extension of the pillar is sometimes necessary. This is placed between the inlet hood and the upper silencer.

UFMS, motor silencer

Additional motor silencer which gives a lower sound level and a uniform tower.

Drainage

If there is a risk of large amounts of water running into the ﬂoor channel, a drainage pipe should be connected to the existing 1” connection (internal thread). Do not connect the drainage to the sewage (risk of blowing out water lock).

UFS, securing strip

The securing strip is mounted round the upper silencer and ﬁxed to the outside wall to avoid the risk of tipping.

Installation alternatives

Fig. 2 The positioning of the columns

The fan pillar can be positioned on either side of the door. For large doors, two fan pillars are often required. They should be positioned one on each side. When two units are placed on each side of the doorway, the ﬂoor channel has to be divided by a steel wall in the middle to prevent the fans from working against each other.

Mounting

Fig. 3 Flange sizes

The pillar is connected to the connection box with ﬂange according to the picture. The UF600 ﬂange comes with Ø12 mm holes.

Fig. 4 Connection box

The connection box is where the pillar is connected to the ﬂoor channel. Please contact Frico for more information.

Fig. 5, 5.1 Floor channel, - cross sections

The ﬂoor channel box is a steel construction that is cast into the concrete ﬂoor. The outlet opening is at ﬂoor level, as close to the ﬂoor opening as possible. The length of the box and the angle and column width is determined at the project planning stage. The channel can be made in one piece or delivered in sections which are then welded together on location and include air outlet slot, connection box and inspection hatch. Measurements are suggestions. The air outlet slot should extend minimum 150 mm outside the door edges on each side. Please contact Frico for more information.

Fig. 6 Air curtain slot

To compensate for the inward-directed pressure force, the air curtain slot is directed at an outward angle of about 15°. The air curtain slot should be at least 300 mm wider than the door opening. If the air outlet slot is more than 300 mm away from the door opening the ﬂoor channel should be prolonged or side protection should be mounted on both sides of the door to increase air curtain effect.
