General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The guarantee is only valid if the
Thermozone units are used in the manner
intended by the manufacturer and in
accordance with the Frico installation and
maintenance instructions.
Application area
The AGV4000 air curtain unit is intended for
installation beside entrances and doors of 1.5
- 2.5 metres (one unit) and 2-5 metres (two
units) in width.
AGV4000 is installed to the side of or on
both sides of the entrance. Two units can be
installed above each other to cover a number
of different entrance heights.
Protection class IP23.
Operation
Air is drawn in at the side of the unit and
blown out towards the entrance so that it
shields the door opening and minimizes heat
loss. To achieve the optimum curtain effect
the unit must extend the full height of the
door opening.
The grille for directing exhaust air is
adjustable and is normally angled outwards to
achieve the best protection against incoming
cold air.
The airflow can be adjusted by use of the fan
speed selector.
The efficiency of the air curtain(s) 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!
Installation
The unit is installed as floor standing using
the floor bracket supplied, which is bolted
into the floor, but must also be secured to
the wall or ceiling, see diagram page 4. AGV
is installed as close to the door as possible,
AGV 4000 A/E
Assembly and operating instructions
preferably against the wall and immediately
beside the doorway. For high entrances two
units can be installed on top of each other
using bolts (in 6 retained nuts).
It must be specified when ordering whether
the air curtain is to be installed on the left or
right hand sides of the entrance (seen from
inside the premises).
Ensure that the service hatch is accessible
and can be fully opened.
See dimension diagrams pages 2-4.
Electrical installation
Electrical connection may only be carried
out by an authorized electrician, and in
accordance with these instructions and the
applicable regulations.
1. The service hatch is opened by slackening
off the screws in the side of the unit as
illustrated on page 3.
2. The unit is connected via one of the cable
glands in the rear side of the unit.
Different combinations for controlling fan
speed and heat output are available. See
wiring diagrams (pages 6 - 10). Connections
are made using EKK, EKLK or corresponding
type cables. The cable glands used must meet
the protection class requirements. For units
with electrical heating, the power and control
voltage can be supplied separately. It must be
indicated in the distribution board that "The
air curtains are supplied from more than one
connection".

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
