IOM SYSAER R32 (IOM SYSAER R32 01 N 2GB)

English
When several SYSAER R32 units are installed, ensure proper clearance is implemented around the
condensers specic to each machine.

22 SYSAER R32
Depending on temperature and outdoor air humidity conditions, water vapour contained in the air can
condense on the nned heat exchanger and even form ice under low outdoor temperature conditions (around
< 5°C). This condensate water and defrosted water runs off via outlets provided under the exchanger. To aid
water run-off and avoid frozen water remaining in the appliance in winter, we recommend that it is mounted
at a height of around 10cm off the ground. In this way, condensate and defrosted water can run off freely
and be absorbed into the ground or channelled to a basin built under the appliance in order to protect the
environment.
In areas where outdoor temperatures fall below 1°C, the system can be equipped with a condensate anti-
freeze protection system (e.g. a heated pipe sheath, Not supplied).
In order to contain noise levels, we equip our appliances with quiet fans and encase the technical compartment
in sound-proofed panels. However, noise levels can be reduced even further by following a few installation
precautions:
² Do not install the appliance near a window.
² Do not install the unit in enclosed or conned yards, narrow locations where noise may be reected
on walls
² Avoid locating the appliance in a corner (increased reverberated noise).
² Install the rubber pads supplied or anti-vibration pads (available as an option) under the appliance.
² Do not join the concrete slab supporting the appliance to the structure of the dwelling (structure-
borne noise transmission).
² Electrical and hydraulic connections to the unit must be exible to avoid transmitting vibrations.
Also Compressors are a typical source of annoying noise, so for the SYSAER R32 they are mounted with
acoustic jacket that can substantially reduce the resulting noise emissions. For an easy installation our
jackets are equipped with clips and adjustable straps that allows ideal adaptation to compressor dimensions.
Those jackets are composed of a PVC outer surface: robust, weather-resistant and easy to clean.
11.1.2. CONDENSATE WATER MANAGEMENT IN HEATING MODE
When choosing the location for the SYSAER
R32, take care to leave sufcient free
clearance on all sides to ensure easy access
for maintenance work.
Indeed, the unit is equipped with a R32
refrigerant leak detection card allowing
it to be shut down and the evacuation of
the hydrocarbon to the outside air (before
reaching the ammability limit of the uid).
For this purpose, two openings are present
on the chassis: the rst, tted with the
exhaust fan, sucks the outside air to the
interior of the frame and the second one
evacuates the stale air into the open air.
These minimum dimensions of the clearance zones must be respected, both to ensure the correct operation
of the unit and to allow access, maintenance, cleaning and, above all, to guarantee the safety of individuals.
