INSTALLATION
Setup
Only set up the unit in
frost-free premises.
The premises should fulfil the following prerequisites:
• Room temperature of between 8 and 35 °C for operation
using room air
• Good insulation to adjoining premises
• Condensate drainage
• No abnormal dust load in the air
• Solid foundation (approx. 500 kg/m
2
)
To ensure problem-free operation of the unit and provide
access for repairs and maintenance, it is recommended to
keep 0.6 m clear in front of the unit.
On setup:
Remove the packaging material from the pallet
1. Remove the corner protectors
2. Remove the transport mounts on the pallet
3. Lift the unit off the pallet and position it
4. Align the unit by turning the adjustable support legs
KVM-Genvex A/S always recommends that you carefully
plan where to set up your Genvex product in relation to the
position of any living room. Since this is an engineering
product fitted with fans and/or a heat pump, this may
result, on rare occasions, in combination with unsuitable
installation conditions, in unsatisfactory noise or vibration.
As a rule, we always recommend that the system be
installed so that it is not immediately adjacent to a bed-
room. As regards the fastening of the Genvex system to the
building structure, we simultaneously recommend that it be
fastened to a heavy structure like, e.g. concrete.
Also make sure that sound or vibrations cannot be trans-
mitted through materials that are in contact with the tech-
nical system. If there is a risk of transmission of sound and
vibrations, we recommend the additional installation
of anti-vibration materials and the soundproofing of the
setup room.
Connecting to a Water Main
During installation, to ensure that there is sufficient
pressure and water where the water is drawn, take into
consideration the pipe dimensions in relation to the existing
water pressure and pressure loss.
The aspects of the installation that have to do with water
must comply with the local HWS regulations. The water
pipes can either be made hard or flexible. However, they
must be approved for drinking water. Take into considera-
tion the corrosive properties of the pipes to avoid damage.
As with all pressurised containers, the tank of the unit must
be fitted with an approved safety valve and an approved
check valve on the supply side (always check the
local requirements).
The inflow of fresh cold water and the outflow of hot water
take place underneath the tank (3/4” RG connection). The
maximum operating pressure is 10 bar, and the maximum
operating temperature is 65 °C.
If necessary, the supply pipe must be fitted with a pressure
reduction valve and possibly with a filter.
When fitting the piping in the dwelling,
avoid contaminating the pipes. If required, flush
the pipes with clean water before connecting the
unit.
When fitting pipes, take care not to
twist the pipe connections. Use a pipe wrench to
apply counter pressure.
If recirculation is not used, make sure that the
recirculation pipe connection is fastened securely.
Connecting to Condensate Drain
Quite a bit of condensate will form due to the cooling of the
air that passes through the heat exchanger. The condensate
drain is fitted with a hose which guides the water to a
proper hose.
Depending on air humidity, the flow can reach 0.5 l/h.
It is a requirement to fit the drain with a sealed water trap
with a minimum water head of 100 mm in order to allow the
water to drain from the unit unhindered.
If the unit is not fitted with such a water trap, the water will
not be able to drain from the tray due to negative pressure,
which can result in water damage.
It is also possible for the unit to suck in air via the drain and
since the drain contains ammonia vapours, this will damage
the cooling system before long.
Failure to fit the water trap properly will void the warranty.
