AR3500

GB  

  AR3500W: The unit is fitted with cable and 

plug.

  AR3500E: The unit is supplied through 

cable glands on the side of the unit. For 
units with electrical heating, power and 
control should be supplied separately. 
Control (230V~) and power supply for heat 
(400V3~) should be connected to a terminal 
block in the terminal box. 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”.

3. Close the service hatch and make sure that 

the snap fixings lock properly.

See wiring diagrams.

Start-up

Note! When using for the first time or when 
starting up after a long period of disuse, a 
small amount of smoke and a slight odour 
may occur temporarily, which is completely 
normal.

Connecting the water coil (AR3500W)

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. 

To access the connections (DN20, 3/4”, 

inside thread) the service hatch and intake 
grille must be opened. The water coil is 
connected inside the unit through holes which 
are made (during installation) on the upper 
side or through the side of the unit, possible 

places are marked with punch marks.

The connections to the heating coil must be 

equipped with shut off valves to allow problem 
free removal.

Adjustment of the air curtain and air flow

The direction and speed of the air flow should 
be adjusted considering the load on the 
opening. Pressure forces affect the air stream 
and make it bend inwards into the premises 
(when the premises are heated and the 
outdoor air is cold).

The air stream should therefore be directed 

outwards to withstand the load. Generally 
speaking, the higher the load, the greater the 
angle that is needed.

Basic setting fan speed

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

Filter (AR3500W)

The heat coil fin distance, in combination 
with the hole diameter of the intake grille, 
protects against dirt and blockage and makes 
a separate filter unnecessary.

Service, repairs and maintenance

For all service, repair and maintenance first 
carry out the following:
1. Disconnect the power supply. 
2. The service hatch is opened by loosening 

the snap fixings located on the down side 
(turn 90°). See fig. 3.

3. After service, repairs and maintenance 

close the service hatch and make sure that 
the snap fixings lock properly.

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.
