5. MECHANICAL INSTALLATION
Caution: Risk of foot injuries!
Prevent unit from dropping during installation! Helping hand of a second person is advisable.
Caution: Risk of electrical shock!
Hazardous electrical voltage. During installation, the unit must be disconnected from power supply and secured against being switched on
again. The absence of voltage must be ensured by a measurement.

Recommendations
When selecting the installation site for the reverse osmosis unit, take the following into account:
• The minimum clearances indicated in the tting measures section must be observed in order to ensure adequate unit venti-
lation and allow for unob- structed access in case of maintenance
• Protection class IP20
• By design, HygroMatik reverse osmosis units are not qualied 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 eects 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 outow according to DIN EN 1717.
• The installation room must be well ven- tilated and equipped with a oor drain. Alternatively, a water stop device (e.g. leakage
detector) can be used.
• Ensure that the system stands rmly.
