Caution
Note
Caution
Caution
Warning
Installation and operation must comply with local
regulations and accepted codes of good practice.
Checks before installation:
• Do the RCME unit, control cabinet and feed pump 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 frostfree 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 antisiphoning valve should be installed or the pipework should be
carried out 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 cabin et
The control cabinet is designed for wall mounting.
The CU 361 must not be exposed to direct sunlight.
7.1.3 SPO 5-55 feed pump
Install the feed pump according to the installation and operating
instructions supplied with the pump.
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.
See section 19.7 Weight of RCME unit.
7.3 Pipework
All external pipes must be properly supported
before they are connected to the RCME unit to
ensure that the internal pipework is not stressed.
We recommend to fit isolating valves on either
side of the unit. It is thus not necessary to drain
the system if the RCME unit requires service.
All pipework subject to freezing conditions must
be adequately insulated.
7.3.1 Rainwater inlet pipe from collecting tank
For thread size and location of the rainwater inlet pipe, see fig. 1,
page 102, and fig. 2, page 103.
7.3.2 Mains water supply pipe and flow sensor
Install the flow sensor in the mains water inlet pipe before the
RCME unit. Observe the flow indication on the flow sensor pipe/
housing.
For thread size and location of the mains water supply pipe,
see fig. 1, page 102, and fig. 2, page 103.
7.3.3 Discharge pip e
Connect the hose supplied with the system between the booster
pump and the base plate outlet.
Connect the piping from the building to the hose connection via
an isolating valve.
For thread size and location of the mains water supply pipe,
see fig. 1, page 102, and fig. 2, page 103.
7.3.4 Overflow
Lead the overflow to a drain via a funnel to en sure that there is a n
air gap between the buffer tank an d the pipe lea ding to the sew er.
See the installation example in fig. 1, page 102.
8. Electrical installation
Warnin g
The electrical connection must be carried out in
accordance with local regulations.
Before making any connections to the unit or the
feed pump, switch off the power supply, and
make sure that it cannot be accidentally switched
on.
We recommend to fit an earth leakage circuit
breaker (ELCB) to the incoming power supply.
Check that the RCME unit and feed pump are
suitable for the power supply at the installation
site.
All electrical connections must comply with
enclosure class IP54.
8.1 Electrical connection
The following connections must be made before the system can
be commissioned.
8.1.1 Connection of power supply

16. Data communication
The CU 361 incorporates hardware that enables communication with external units, such as a computer, via an external GENIbus or
Ethernet connection.
Fig. 34 Data communication via external GENIbus and Ethernet connections
16.1 Ethernet
Ethernet is the most widely used standard for local networks
(LAN). The standardisation of this technology has created some
of the easiest and cheapest ways of creating communication
between electrical units, for instance between computers or
between computers and control units.
The web server of the CU 361 makes it possible to connect a
computer to the CU 361 via an Ethernet connection. The user
interface can thus be exported from the CU 361 to a computer so
that the CU 361 and consequently the RCME system can be
remotely monitored and controlled.
In order to use the web server, you must know the IP address of
the CU 361. All network units must have a unique IP address to
communicate with each other.
It is possible to change the factory-set IP address by
configuration or by activating a DHCP (Dynamic Host
Configuration Protocol), either directly in the CU 361 or via the
web server. See the example in fig. 35.
We recommend that you protect the connection
to the CU 361 in consultation with the system
administrator according to your safety
requirements.
TM05 2141 4511
Dynamic assignment of an IP address for the CU 361 requires a
DHCP server in the network. The DHCP server assigns a number
of IP addresses to the electrical units and makes sure that two
units do not receive the same IP address.
Use a standard internet browser when connecting to the web
server of the CU 361.
If you want to use the factory-set IP address, no changes are
required in the display. Open the internet browser, and enter the
IP address of the CU 361.
In order to use dynamic assignment, the function must be
enabled. Click [ok] "Use DHCP". A tick shows that the function
has been enabled. Open the internet browser, and enter the
CU 361 "Host name" instead of the IP address (the host name is
stated at the top of display 4.5.5). The internet browser will now
try to establish connection to the CU 361.
DHCP requires a host name.
The host name can only be changed by means of
a GSC file (configuration file) or via a web server.
See section Change of network setting, page 21.
This is the first display that appears when connecting to the
CU 361.

Note
17. Maintenance
17.1 CU 361
The CU 361 is maintenance-free. It must be kept clean and dry.
Protect it from direct sunlight. The temperature of the CU 361
must not exceed the limits of ambient temperature.
See section 19. Technical data.
17.2 Regular inspections
The RCME system should be inspected at regular intervals.
This must be carried out when the system has been shut down.
Check the following:
• Check that there are no leaks on the internal pipework, the
pump and the buffer tank.
• Check the precharge pressure of the pressure vessel and
adjust, if necessary. See section 17.3 Integrated pressure
vessel.
• Check that the booster pump operates quietly and smoothly
without vibration or excessive noise.
Should any faults be found, see section 21. Fault findi ng.
After inspection ensure that the isolating valves are fully open,
and that the power supply to the RCME system is switched on
again.
17.3 Integrated pressure vessel
Check and adjust the precharge pressure of the vessel before the
booster pump is filled with water. If the system has already been
filled and the pump has been running, proceed as follows:
1. Switch off the power supply to the RCME system.
2. Release the water pressure by opening a tap in the discharge
pipe of the system. Leave the tap open while checking and
adjusting the precharge pressure.
3. The precharge pressure can now be checked using a car tyre
pressure gauge. The air valve is located in the top right-hand
corner of the pump mounting plate.
For small pressure adjustments a foot pump can be used. If
large amounts of gas are required, use dry nitrogen to prevent
corrosion within the vessel.
Setting example:
If the discharge pressure has been set to 4.5 bar, the
precharge pressure must be 4.5 x 0.7 = 3.15 bar.
Warning
Before starting any work on pumps, terminal
boxes or control cabinet, the power supply must
have been switched off for at least five minutes,
and it must be ensured ensure that it cannot be
accidentally switched on.
Set the precharge pressure of the vessel to 70 %
of the setpoint selected on the booster pump
control panel (booster pump discharge
pressure).
Measure the precharge pressure while the
system is pressureless.
If the precharge pressure is not set correctly, this
may result in incorrect operation of the RCME
unit.
18. Taking the RCME system out of operation
Take the RCME system out of operation by switching the main
switch off.
Warnin g
The conductors to the main switch are still live.

Advarsel
Følg lokale forskrifter og gængs praksis ved
installation og drift.
Kontrol før installation:
• Svarer RCME-enheden, styreskabet og fødepumpen til
ordren?
• Er de synlige dele intakte?
7.1 Placering
7.1.1 RCME-enhed
RCME-enheden skal opstilles på et tørt og frostfrit sted med god
ventilation hvor den ikke bliver udsat for ekstreme temperaturer.
For at reducere bakterievækst bør omgivelsestemperaturen være
lavere end +20 °C. Enheden kan placeres udendørs med en
afskærmning som er bestandig over for vejrlig, frost og gnaverangreb, og som er godt ventileret, specielt i varme perioder.
RCME-enheden må ikke installeres unde r tag. V ibrationsniveauet
som er forbundet med roterende udstyr, vil give forstyrrelser, og
hvis der opstår en utæthed, kan det resultere i betydelige vandskader.
Hvis RCME’en er installeret i en kælder og bufferbeholderen er
installeret i et lavere niveau end opsamlingsbeholderen, kan der
opstå hævertvirkning fra opsamlingsbeholderen til bufferbeholderen. For at forhindre dette, bør der installeres en antihævertventil,
eller rørføringen skal udføres på en sådan måde at hævertvirkning forhindres.
Placér RCME-enheden så der er tilstrækkelig plads til at vedligeholde og servicere enheden.
Installér et egnet afløb og beskyttelse mod vandskade i umiddelbar nærhed af RCME-enheden.
7.1.2 Styreskab
Styreskabet er beregnet til montering på væg.
CU 361 må ikke udsættes for direkte sollys.
7.1.3 Fødepumpe SPO 5-55
Installér fødepumpen i henhold til monterings- og driftsinstruktionen der er leveret sammen med pumpen.
7.2 Fundament
Opstil RCME-enheden på den medleverede fodplade.
Fodpladen skal anbringes på en jævn og fast overflade som kan
holde til vægten af enheden med fyldt bufferbeholder, fx et betongulv eller -fundament. Se afsnit 19.8 Mål.
7.3 Rørinstallation
Alle eksterne rør skal være forsvarligt
understøttet inden de tilsluttes til RCME-enheden
så der ikke opstår spændinger i den interne
rørføring.
Vi anbefaler at montere afspærringsventiler på
hver side af enheden. Derved undgår man at
tømme anlægget hvis RCME-enheden skal serviceres.
Alle rør der er udsat for frost, skal være tilstrækkeligt isolerede.
7.3.1 Tilgangsledning til regnvand fra opsamlingsbeholderen
For gevindstørrelse og placering af tilgangsledning til regnvand,
se fig. 1, side 102, og fig. 2, side 103.
7.3.2 Forsyningsledning til vandværksvand og flowsensor
Montér flowsensoren i forsyningsledningen til vandværksvand før
RCME-enheden. Vær opmærksom på strømningsretningen der er
angivet på flowsensorrøret/-huset.
For gevindstørrelse og placering af forsyningsledning til vandværksvand, se fig. 1, side 102, og fig. 2, side 103.
7.3.3 Afgangsledning
Forbind slangen som leveres sammen med anlægget,
mellem trykforøgerpumpen og fodpladens afgang.
Forbind rørføringen fra bygningen til slangen via en afspærringsventil.
For gevindstørrelse og placering af forsyningsledning til vandværksvand, se fig. 1, side 102, og fig. 2, side 103.
7.3.4 Overløb
Overløbet skal føres hen til et afløb via en tragt for at sikre at der
er luft mellem bufferbeholderen og røret der fører hen til
kloakken. Se installationseksempel i fig. 1 på side 102.
8. Elektrisk installation
Advarsel
Eltilslutning skal foretages i henhold til lokale
forskrifter.
Afbryd strømforsyningen, og sørg for at den ikke
uforvarende kan genindkobles, inden der fore-
tages tilslutninger til enheden eller fødepumpen.
Vi anbefaler at der tilsluttes et fejlstrømsrelæ til
strømforsyningen.
Kontrollér at RCME-enheden og fødepumpen er
beregnet til strømforsyningen der findes på
installationsstedet.
Alle elektriske tilslutninger skal overholde
kapslingsklasse IP54.
8.1 Eltilslutning
Følgende tilslutninger skal udføres inden anlægget kan sættes
idrift.
8.1.1 Tilslutning af strømforsyning
