Installation and operating instructions

General Instructions

Read these instructions carefully prior to 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 should the product be used in the manner intended and in accordance with the instructions.

Application

Pamir 2500 has a recommended installation height of 2,5 m. The air curtain is available without heat, with electrical heating and with water heating. Protection class for units with electrical heating: IP20.
Protection class for units without heating and units with water heating: IP21.

Operation

Air is drawn in at the top of the unit and blown downwards shielding the door opening and minimizing heat loss. To achieve the optimum curtain effect the unit must extend the full width of the door opening.
The grille for directing the outlet air is adjustable and is normally angled outwards to achieve the best protection against incoming air.
The efficiency of the air curtain depends on the air temperature, the pressure differencial across the doorway and any wind load.
NOTE! Negative pressure in the building considerably reduces the efficiency of the air curtain. The ventilation should therefore be balanced.

Mounting

The air curtain is installed horizontally with the outlet air grille facing downwards as close to the door as possible. The product must be mounted in such a way to allow future service and maintenance. Minimum distance from outlet to floor for electrically heated units is 1800 mm. For other minimum distances, see Fig. 4.

Mounting with wall brackets (fig. 6)

1. Mount the brackets on the wall, see Fig. 6A and dimension drawing Fig. 1. If the wall is uneven the brackets must be compensated for this.
2. Hook on the unit at the lower edge of the brackets. (Fig.6B)
3. Bend the top of the console over the unit and slide the unit’s screws along the rail into the slots on the consoles. (Fig.6C) When the bracket is bent once, it must be replaced if bent back more than 45 °.
4. Lock the nuts against the brackets. (Fig.6D)

Horizontal mounting on the ceiling

Threaded rods, hanging brackets, and ceiling mounting brackets for ceiling mounting are available as accessories, see accessories pages and separate manuals.

Electrical installation

The installation, which should be preceded by an isolator switch with a contact separation of at least 3 mm, should only be wired by a competent electrician and in accordance with the latest edition of IEE wiring regulations.
The air curtain has an integrated PC board which is connected to the selected external control system FC. FC must be ordered separately. The PC board is accessed via cable glands on the top of the unit. See Fig. 2. FC is supplied pre-programmed. Communication- and sensor cables are connected to the PC board.

Should more than one air curtain be controlled by a single FC, an additional communication cable FCBC per unit will be required. See manual for FC.
Unit without heating or with water heating Connected via the built-in control board with 1,5 m cord and plug.

Unit with electrical heating

The electrical connection is made on the top of the unit. Pierce the gland with a screwdriver before entering the cable. See Fig. 2. Control (230V~) and power supply for heat (400V3~) should be connected to a terminal block in the terminal box. 2-metre and longer units require dual power supplies. See dimension drawings.
The largest cable diameter for the terminal block is 16 mm². The cable glands used must meet the protection class requirements. In the distribution board, it is to be indicated that ”the air curtains can be supplied from more than one connection”.

1. 2 m units are connected with two power supplies.
2. Dimensioning of external wiring shall comply with applicable regulations and local deviations may occur.

Start-up (E)

When the unit is used for the first time or after a long period of non-use, smoke or an odour may result from dust or dirt which has collected on the element. This is completely normal and disappears after a short time.

Connecting the water coil (W)

The installation must be carried out by an authorised installer.
The water coil has copper tubes with aluminium fins and is suitable for connection to a closed water heating system. The heating coil must not be connected to a mains pressure water system or an open water system.
Note that the unit shall be preceded by a regulating valve, see Frico valve kit.
The water coil is connected on the upper side of the unit with ø15 mm smooth copper pipe with a suitable coupling and internal liner. Soldering is not recommended. The connections to the heating coil must be equipped with shut off valves to allow trouble-free removal. The water coil is equipped with a drain valve. A vent valve should be connected at a high point in the pipe system. Air valves are not included.
NOTE: Care must be taken when connecting the pipes. Always use an internal liner in the pipe connections to prevent straining of the pipes and subsequent water leakage.
Adjustment of the air curtain and airflow The direction and speed of the airflow should be adjusted considering the load on the opening. Pressure forces affect the airstream and force it inwards towards the premises
(when the premises are heated and the outdoor air is cold). The airstream should, therefore, be directed outwards to withstand the load. Generally speaking, the higher the load, the greater the angle required.

Basic setting fan speed

The fan speed when the door is open is set using the control. Note that the airflow direction and the fan speed may need fine adjustment depending on the loading of the door.

Filter (W)

The water coil is protected against dirt and blockage by an internal air filter which covers the coil face. In environments where the filter requires frequent cleaning, it is advisable to use an external intake filter (see accessories pages), which provides easier maintenance, since the unit does not need to be opened. When an external filter is used, the internal filter is removed.

Service, repairs and maintenance

For all service, repair and maintenance first carry out the following:

1. Disconnect the power supply.
2. The front hatch is removed by removing the screws on the top of the unit and then detach the bent edge at the bottom. (Fig.3)
3. After the service, repair and maintenance reattach the front hatch. Place the hatch at the lower edge with the bent edge and fasten on top with screws.

Maintenance

Unit with water heating

The appliance filter should be cleaned regularly to ensure the air curtain effect and heat emission from the device. How often depends on local circumstances. A clogged filter is not a risk, but the appliance function can fail.

1. Disconnect the power supply.
2. The front hatch is removed by removing the screws on the top of the unit and then detach the bent edge at the bottom. (Fig.3)
3. Remove the filter and vacuum clean or wash it. If the filter is clogged or damaged, it may need to be changed.

All units

Since fan motors and other components are maintenance-free, no maintenance other than cleaning is necessary. The level of cleaning can vary depending on local conditions. Undertake cleaning at least twice a year. Inlet and exhaust grilles, impeller and elements can be vacuum cleaned or wiped using a damp cloth. Use a brush when vacuuming to prevent damaging sensitive parts. Avoid the use of strong alkaline or acidic cleaning agents.

Temperature control

Temperature control of FC maintains the exhaust temperature. Should the temperature exceed the preset value, the overheating alarm will activate. For more information see the FC manual.

Overheating

Unit with electrical heating
The air curtain unit with electrical heating is equipped with an overheat protection. If it is deployed due to overheating, reset as follows:

1. Disconnect the power supply with the isolator switch.
2. Determine the cause of overheating and rectify the fault.
3. Remove the front hatch.
4. Press the red button located inside the air curtain unit, at the inner gable of the terminal box.
5. Reattach the front hatch and connect the unit again.

• All units
  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.

Replacing heating elements/heating package (E)

1. Mark and disconnect the cables to the heating elements/package
2. Remove the mounting screws securing the heating elements/package in the unit and lift the heaging elements/package out.
3. Install the new heating elements/package in reverse order to the above.

Troubleshooting

If the fans are not running or do not perform properly, check the following:

• The power supply.
• That the intake grille/filter is not dirty.
• That the motor’s safety cut-out has not been deployed.
• Functions and settings of the FC control system, see the FC manual.

If there is no heat, check the following:

• Functions and settings of the FC control system, see the FC manual.

For units with electrical heating, also check the following:

• Power supply to electric heater coil; check fuses and circuit-breaker (if any).
• That the overheat protection has not been deployed.

For units with a water coil, also check the following:

• That the water coil is air free.
• That there is sufficient water flow and pressure.
• That incoming water is heated adequately.

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

Residual current circuit breaker (E)

When the installation is protected by means of a residual current circuit breaker, which trips when the appliance is connected, this may be due to moisture in the heating element. When an appliance containing a heater element has not been used for a long period or stored in a damp environment, moisture can enter the element.
This should not be seen as a fault, but is simply rectified by connecting the appliance to the main supply via a socket without a safety cut-out so that the moisture can be eliminated from the element. The drying time can vary from a few hours to a few days. As a preventive measure, the unit should occasionally be run for a short time when it is not being used for extended periods of time.
