Specifications

Air Systems
Side duct anges
Fitted as standard on units 90, 120 and 150, this accessory
is composed of easy to install sheet metal panels to allow
ductwork connections on the side of the AHU for horizontal
return air and/or supply air.
Kit conversion propane
This kit comprises replacement burner, pilot injectors
and all necessary instructions for converting the natural
gas burner to propane gas. The nominal pressure of the
propane gas should be 37 mbar.
High heat gas
This kit comprises replacement burner injectors and all
necessary instructions to provide high heat capacity for
gas rooftop.
Hot water coil with control
The hot water coil and his control are always tted, wired
and factory tested. Located in the supply air section,
side or bottom duct connection is possible without any
modication. Complete with an anti-frost thermostat, the
PCB will activate the modulated valve (24V supply, 0 – 10V
modulating signal) in order to get the best comfort. A
jumper will allow using hot water coil as 1st heating stage.
Electric heaters
Available on cooling only and Heat pump units, the electric
heater is protected with two overheats per element.
When the overheat operates, there is a lock out of the
faulty electric heater stage and the PCB starts automatically
another heat stage.
Air lters
G4, F6 and F7 lters are available to purify the air in the
room. M1 re class and manufactured in sheet metal frame,
they are easy to install and clean.
Indoor fan soft start
Compact control unit with a motor with AC semiconductors,
designed for soft starting and stopping of three-phase
motors for centrifugal fans. The starting time, the stopping
time and the initial torque are adjusted by mean of
independent potentiometers.
Return fan
Used to overcome high return path pressure drops, works
in series with the indoor fan to maintain the air pressure of
the conditioned space within acceptable levels.
Grill condenser protection
Metallic frame painted with oven-baked polymerized paint
(800h salt spray resistance) to protect the ns of the coils
from external damages.
Fixed and adjustable roof curbs
Ideal for down-ow applications, it is a great help for
installation allowing duct connections, electrical connection
and weatherproong between the roofcurb and the roof
of the building. Shipped in kit form, it also gives sufcient
height for condensate trap operation.
The adjustable roof curbs have the same benets as the
xed roof curb, it allows the rooftop to be levelled on a roof
with up to 7° slope (4%).
Antivibration mounting kit
It is composed by a set of stainless steel springs, to be
assembled underneath the rooftop in a specic position.
Their installation avoids the potential vibration transmission
of the equipment to the building and reduces therefore the
noise level (compressors have their own shock absorbers
delivered as standard).
Energy recovery
Attached to the return air box of the rooftop, a rotary
enthalpy wheel retrieves the energy of the exhausted air
and transmits it to the fresh air intake. A special material
used in the wheel allows that latent heat as well as sensible
heat are transmitted.
