Installation and Operating Instructions

Application area

Frico Thermozone WAC 200 is an air curtain unit
intended for permanent installation above

entrance doors and smaller doors up to 3 meters.
The efficiency of the curtains is dependent on the
size of the load on the door in question.
Thermozone WAC 200 is supplied with a hot water
heating coil and is mounted above the door.
Protections class IP44.

Operation

Air is drawn in from the front of the unit and is
blown out downwards so that is screens the door
opening and minimises any heat leakage through
it. The air speed is adjusted in two stages using the
speed selector.
Note that if there is negative pressure in the
building the efficiency if the air curtain is

significantly reduces. Ventilation should be
balanced.

GB

Electrical installation WAC

The electrical connection to the fan motors is
made using a lead with a plug, which is connected

to an appropriate 230 V~ socket. One of the
knockouts located on the top of the unit is used to
enter the control cable. Connection of the control
cable may only be carried out by a qualified
technician. There are several different options for
controlling the speed of the motors. See the wiring
diagram.

Connection of the water coil

Installation should be carried out by a qualified
technician and in accordance with applicable
directives. The connections DN 15 (1/2") with
internal threads can be found in top of the unit.
The plug for emptying the water is located in the
connection area on the lower part if the inlet pipe.

The connection area is accessible once the front
grille has been removed.

Assembly

The unit may only be installed horizontally with a
downward output air direction. Several units can
be fitted side-by-side across the wide door
openings. The unit may be installed as close to the

ceiling as possible. The only limitation is the pipe
connections. For other dimensions and minimum
assembly distances, see fog.

a) Fitted on the wall or beam

• The thermozone hangs from two keyhole slots,
three on WAC 202, located on the rear of the
unit. Suitable bolts could be M6S M6. NOTE!

The unit must be secured using the keyhole
slots. The strip can be fitted either facing
upward or downward, see the detail fig.

• Thermozone can be bolted directly to the wall/
beam. There are four M6 blind nuts, six on
WAC 202, located on the rear of the unit for this
purpose.

b) Suspended using drop rods

There are four, six on WAC 202, M10 blind nuts
on top of the unit for securing drop rods, with
paired centre-to-centre spacing of 100 mm, see
fig. Brackets for suspended mounting are
available as accessories.

Safety

Ensure the area around the unit’s intake and
exhaust grilles is kept from material that can
prevent the air flow through the unit.!
During operation the surfaces of the unit are hot!

Maintenance

As the fan motors and other components are
maintenance free no maintenance is necessary
other than cleaning when required, however, at
least once a year. WAC units are equipped with a
filter that protects against contamination and
blockage. The filter should be cleaned regularly to

ensure the curtain effect and heating output
produced from the unit.

Water control

VR 20 together with a thermostat, e.g. KRT 1900 is
a good solution for controlling the heat in WAC. A
VR consists of four components and should be
fitted as set out in the figure below, also see the

detail manuals found in respective VR sets.

1.Shutoff valve

2.Trimming valve with shutoff option

3.Three-way motor valve

4.Bypass valve

VR20 has DN 20 (3/4") connections, except the
bypass valve that has DN 10 (3/8").

Documenting the output, pressure, and flow
requirement

There are three different documenting methods.

1. Given water temperatures:

WAC is documented here with the desired water
temperatures on supply and return pipes. The air
flow through the WAC is given by the speed of the
fans. The highest and lowest speeds are
documented. Output data from this table are
output, required water flow and the pressure drop

on the water side. The air temperature from the air
curtain is also presented.

2 . Given water flow and input temperature of
the water:

WAC is documented here based on a pressure drop
of 10 kPa across the coil. At this pressure drop a
specific quantity of water can be pushed through

the coil. Output data is output, temperature of the
output air and the return water temperature.

3 . WAC + VR:

WAC with VR control is documented here. The
valve set can be connected to several WAC units

and are documented here with different
combinations based on the width if the door. There
are two different dimensions for VR. VR20 has
connection thread DN20 (3/4") and VR25 is
connected with DN25 (1"). VR25 has a lower
pressure drop than VR20 and can therefore be
used when a greater flow is required. In this
presentation the air temperature is locked in the

WAC at 15°C and the pressure drop across the
entire VR set +WAC is set to 15 kPa.
For surrounding temperatures, from which the
Thermozone draws air, other than 15°C it is
necessary to multiply the output (P
