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 AGV4000W 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. AGV4000W is intended
for connection to a water heating system.
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
AGV 4000 W
Assembly and operating instructions
is installed as close to the door as possible,
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 2-3.
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 are available. See wiring diagrams
(pages 7-9).
Water coil connection
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.
The water pipes are connected to the
terminals with DN20 (3/4"), internal thread on
the rear of the unit. Use a wrench or similar
to hold the air curtain connections to prevent
straining the pipes and subsequent water
leakage during connection to water supply
pipe-work.
The connections to the heating coil must be
equipped with shut off valves to allow problem
free removal. The highest point of the pipes
supplying the unit with water must also be
fitted with a bleed valve. The installation must
be carried out by an authorised installer.
