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
PAEC2500 is an air curtain for cold storage and freezer rooms as well as entrances.
Installation height for cold storage is up to 4 metres. Recommended installation height for entrances is 2,5 metres. The air curtain has stepless control using an internal or external potentiometer (accessory).
Protection class: IP44.

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 unit is installed horizontally with the outlet air grille facing downwards as close to the door as possible. When the unit is used to protect cold storage or freezer rooms,
it must be mounted on the outside of the conditioned space.
Brackets and torx bit are enclosed in the gable end packaging upon delivery. Mounting with wall brackets (fig. 4)

1. Mount the brackets on the wall, see fig.4A 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.4B)
3. Bend the top of the console over the the unit and slide the units screws along the rail into the slots on the consoles. (Fig.4C) When the bracket is bent once, it must be replaced if bent back more than 45 °.
4. Lock the nuts against the brackets. (Fig.4D)

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.

Connection
The unit is connected with a 1.5m cord and plug.
Control options
Stepless airflow control
The airflow is set manually on the internal potentiometer 0-10V, which is located inside the outlet grille.

Stepless airflow control with external potentiometer
The airflow is set manually on an external potentiometer 0-10V.

Stepless airflow control with door contact/position limit switch
When the door is closed the fan runs at low speed, set on the internal potentiometer 0-10V, which is located inside the outlet grille. When the door opens, the fan runs at high speed, set on an external potentiometer. This control option gives low response time and the best protection.

BMS control
The air curtain can also be controlled via BMS (0-10V).

See Figure 2 and Accessories pages.

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.

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.

Note : that when carrying out work where the end is removed, the outlet grille also detaches.

Maintenance
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.

Overheating
The motors have built-in protection against overheating and will automatically regulate their speed at high temperatures.

Replacing motor or impeller

1. Remove the front.
2. Remove gable end.
3. Remove the screw between motor and fan.
4. Disconnect the cables to the motor.
5. Remove the screws securing the motor and lift it out together with the impeller.
6. Install the new motor and/or the new impeller as above in reverse order.

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

• The functions and settings of the built-in control system.
• That the intake grille/filter is not dirty. ‘
• If the fault cannot be rectified, please contact a qualified service technician.

Packaging
Packaging materials are chosen with consideration to the environment and are therefore recyclable.

Handling of product at end of working life
This product may contain substances necessary for the functionality of the product but potentially dangerous for the environment. The product should not be disposed of mixed with general household waste but delivered to a designated collection point for environmental recycling.
