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.
5.1 Environment Parameters to be met and Mounting
Recommendations
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 venti-
lation and allow for unobstructed access in case of maintenance
• Protection class IP20
• By design, CAREL reverse osmosis units are not qualified for outdoor installation (electronical 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 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 environmental
conditions.
• Make use of existing water connections for supply and draining.
• Mount the unit on a stable, preferably solid wall with the required load-bearing capacity required (s. unit technical specifica-
tions). If such a wall is not at hand, the unit may be attached to a stand bracket firmly anchored to the floor.
• For correct operation it is necessary that the unit is mounted vertically and horizontally perpendicular.
• The optimal feed water pressure of the reverse osmosis (RO) units is in the range of 2 bar to 5 bar. If these values are not rea-
ched, the installation of a pressure reducer or a booster pump is necessary.
• The on-site waste water connection must be a free outflow according to DIN EN 1717.
• The installation room must be well ventilated and equipped with a floor drain. Alternatively, a water stop device (e.g. leakage
detector) can be used.
5.2 Installation steps
5.2.1 Feed water connection
» Connect the feed water inlet to the system. The diameter of the raw water pipe must be at least equal to the
diameter of the connection piece.

» Observe the information in the technical data.
» Connect a shut-off valve upstream of the system.
