Checks before installation:
• Does the product correspond to order?
• Are all visible parts intact?
7.1 Location
7.1.1 RCME unit
The RCME unit should be sited in a dry, well-ventilated and frost-
free position where it will not be exposed to extremes of
temperature. In order to reduce bacteria growth, the ambient
temperature should ideally be less than 20 °C. The unit may be
located outdoors in a weather-, frost- and rodent-proof enclosure
with adequate ventilation, especially during hot weather.
The RCME unit must not be installed into roof spaces.
The vibration level associated with any rotating equipment will
cause disturbance, and if a leak occurs, considerable water
damage could result.
If the RCME unit is installed in a basement and the buffer tank is
installed below the collecting tank, siphoning may occur from the
collecting tank to the buffer tank. In order to prevent this, an anti-
siphoning valve should be installed or the pipework should be
designed in such a way that siphoning is prevented.
Provide drainage facilities for the unit for use in case of leakage,
overflow or loss of water during commissioning and service.
Position the RCME unit to allow access for maintenance and
service.
Provide adequate drainage facilities and protection from water
damage in the immediate vicinity of the RCME unit.
7.1.2 Control cabinet
The control cabinet is designed for wall mounting.
The CU 372 must not be exposed to direct sunlight.
7.1.3 SB 3-45 feed pump
Install the feed pump according to the installation and operating
instructions supplied with the pump.
7.1.4 Hydrostatic pressure sensor for collecting tank
Place the hydrostatic pressure sensor close to the bottom of the
collecting tank.
7.2 Foundation
Position the RCME unit on the supplied base plate. The base
plate must be placed on an even and solid surface capable of
supporting the weight of the unit with filled buffer tank, for
instance on a concrete floor or foundation.

Warning
Installation and operation must comply with local
regulations and accepted codes of good practice.
Caution
The sensor cable must not be kinked or pinched
as this can result in faulty measurements.
Max. bending radius: 120 mm.
Ensure that moisture does not enter the sensor
cable sheath.
