Adjustable roof curbs:
With the same benets as the xed roof curb, it allows
the rooftop to be levelled on a roof with up to 7°
slope (4%).
Fire detection thermostat:
This re detection thermostat is protecting the AHU but
must not be used to ensure a full building protection
against re danger. The standard AHU is protected as
standard with a Supply Air probe that shuts the unit down
(lockout) when temperature exceeds 80°C.
The electro-mechanical re detection thermostat is used to full specic local
requirement. A manual reset is necessary.
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.
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
modication. 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.
High heat gas:
This kit comprises replacement burner injectors and all
necessary instructions to provide high heat capacity for
gas rooftop
Electrical heaters:
Available on cooling only and Reverse cycle 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.
Washable air lter:
The Galvanised sheet metal frame permits cleaning of the
synthetic bre lter but also allows easily replacement of
the media. Delivered with G4 class media in accordance
with European standard EN-779 and F1 re class in
accordance with DIN53438, this is a good solution for
a heavy maintenance site.
Rooftop
Fixed roof curbs:
Ideal for down-ow applications, it is a great help for
installation allowing duct connections, electrical connection
and weatherproong between the roofcurb and the roof
of the building. Shipped in kit form, it also gives sufcient
height for condensate trap operation.
Smoke detector:
The smoke detector is protecting the AHU but must not be
used to ensure a full building protection against smoke
danger. If smoke is detected the AHU is shutdown
(lockout). A manual reset is necessary.
