Notes on supply connections:

Cold, hot and demineralised water, high-pressure steam, condensate and compressed air

supplies can be routed through the ceiling or, alternatively, through the floor. A combination of
the two is not possible.
When installing a run of several washer-disinfectors, drain hoses can be passed through a
made-to-measure floor tray to a central drain.

Notes on supply connections:

Cold, hot and demineralised water can be routed through the ceiling or, alternatively, through the floor.
A combination of the two is not possible. Cooling circuit feed and return pipes for steam condenser
(optional) through ceiling only. Easily accessible central stopcock and main switch recommended.

Waste water connection:

The on-site drain pipe serving the machine drain hose should be located at the side of the machine.
Service ports in the machine casing can be made on site for connection to on-site utilities. Drain hoses
are of a sufficient length to extend to the ports and should be extended outside the machine casing.
Ports should be 36 mm in diameter. Two grommets, Mat. no. 2723340, required to provide anti­scuffing hose protection.
Two blind stoppers, Mat. no. 27119630, are required to provide anti-scuffing protection for condensate
and steam condenser hoses. Blind stoppers should be cut open on site.
When installing a run of several washer-disinfectors, drain hoses can be passed through a made-to­measure floor tray to a central drain. Connection to a common drain pipe above the machines is also
possible. This option requires the use of a strain-relief bush for the drain hoses. If a steam condenser
is supplied from a potable water supply, the machine should be connected to the drainage system
using the non-return device provided. The max. head height of the pumps should should be taken into
consideration!
All drain hoses from washer-disinfectors should be connected to the on-site drain pipe using pressure­tight connections.

Electrical connection:

Electrical supply lines can be routed through floor or ceiling. Min. cable length of 1500 mm above
finished floor surface required with access through floor. Min. cable length of 4000 mm from top edge
of top-box panelling required with access through ceiling.

Standard installation, chemical supply connections:

Install supply lines vertically from ceiling, adjust and locate. All pipework, including insulation, fittings
and valves with taps should be located within the designated area (520 mm × 130 mm). No part of the
installation should extend beyond this area.
Hot, cold and demineralised water lines end with a ¾" threaded union 2,160 mm above finished floor.

If the machine is fitted with a steam condenser, install the cooling circuit feed and return pipes vertically
from the ceiling, and adjust and secure them as necessary. The cooling circuit feed and return pipes
end in the machine installation area with hose sleeves at a height of 2,160 mm above finished floor
(OKFF). Both are connected to the steam condenser with a flexible hose (int. diameter 14 mm) which
is to be provided on site. In the absence of cooling circuit, connect steam condenser to cold water.

Easily accessible central stopcock and main switch recommended.

Stand: 01.07.2010

Alternative installation, chemical supply connections:

Route supply lines through floor to approx. 200 mm above finished floor and secure. Supply lines are
shortened after installation of plinth/floor tray. If plinth/floor tray is planned later, use pipe caps to close
pipes.
Install floor tray horizontally using spirit level. Stopcocks in the chemical supply lines are installed after
the floor tray has been fitted. Pipework and stopcocks should rise by no more than 90 mm above
finished floor and should on no account rise above plinth/floor tray.

If the machine is fitted with a steam condenser, install the cooling circuit feed and return pipes vertically
from the ceiling, and adjust and secure them as necessary. The cooling circuit feed and return pipes
end in the machine installation area with hose sleeves at a height of 2,160 mm above finished floor
(OKFF). Both are connected to the steam condenser with a flexible hose (int. diameter 14 mm) which
is to be provided on site. In the absence of cooling circuit, connect steam condenser to cold water.
Easily accessible central stopcock and main switch recommended.

On-site front panelling:

In the case of two-door (barrier) machines (G7824), a removable and lockable panel must be provided
on site for installation above the door at the same height as the MAV panelling (512 mm). The lid, Mat.
no. 5968080, is fitted above this panel.

Standard installation:
A cover with water-tight pass-through cut-outs for supplies must be provided above the machine to
prevent water ingress into the washer-disinfector in the event of leakage from stopcocks or hose
connectors.

Waste air installation:

In order to expel vapours, air throughput of 150 m³/h for each machine is required on the unclean side
of the operation.

Connection to external vent system with or without steam condenser:

Connection of the washer-disinfector to an external vent system is via an extractor canopy. An air gap
of at least 80 mm should be provided. A suitable vent canopy is provided with the washer-disinfector.
The use of a two-stage fan is recommended (cf. Technical Data Sheet 'Electrical connection' on fan
control). Laying a flexible duct to directly above the machine facilitates installation.

Venting to atmosphere:

The canopy provided should not be fitted if the washer-disinfector is vented directly to atmosphere.
Never merge vent ducts from multiple washer-disinfectors! Vent each machine separately!
