5. Mechanical installation
Risk of foot injuries!
Prevent unit from dropping during installation!
Helping hand of a second person is advisa-
ble.
Risk of electrical shock!
Hazardous electrical voltage.
During installation, the unit must be discon-
nected from power supply and secured
against being switched on again. The
absence of voltage must be ensured by a
measurement.
5.1 Environment Parameters to
be met and mounting recom-
mendations
When selecting the installation site for the
reverse osmosis unit, take the following into
account:
• The minimum clearances indicated in
the fitting measures section must be
observed in order to ensure adequate
unit ventilation and allow for unob-
structed access in case of maintenance
• Protection class IP20
• By design, HygroMatik reverse osmosis
units are not qualified for outdoor installa-
tion (electronic components and water-
bearing parts may be damaged)
• Ambient temperature must lie between
+5 and +40 °C (+41 and +104 °F) in
order to protect the unit electronics
against damage; frost may damage the
steam cylinder, the solenoid valve and
pump, as well as make hoses burst
• Avoid environments with excessive
humidity, as it could have negative
effects on the electronics.
• Installation in closed rooms requires
aeration and, if necessary, temperature
conditioning in order to meet the envi-
ronmental conditions.
• Make use of existing water connections
for supply and draining.
• For proper functioning of the level con-
trol, plumb and level installation of the
unit is required.
• The optimal feed water pressure for the
reverse osmosis units is in the range of
2 bar to 5 bar. If these values are not
reached, the installation of a pressure
reducer or a booster pump is neces-
sary.
• The on-site waste water connection
must be a free outflow according to DIN
EN 1717.
• The installation room must be well ven-
tilated and equipped with a floor drain.
Alternatively, a water stop device (e.g.
leakage detector) can be used.
• Ensure that the system stands firmly.
