Technical description

The cassette toilet consists of a toilet permanently installed in the vehicle and a removable, mobile cassette as a holding tank. The cassette is externally accessible through a door. Depending on the model, the cassette toilet is supplied with rinse water from the vehicle-side freshwater tank or a tank integrated in the housing. The following model versions of the cassette toilet are available:

• CT4050, CT(E)4110: detached, without water tank, without console
• CTLP4050, CTLP4110: detached, without water tank, low console
• CTS 4050, CT(E)S4110: detached, without water tank, with console
• CTW4050, CTW4110: detached, with water tank in the console
  The 4050 models can be installed in a wet room.

5.1 Description of the components

Installing the cassette toilet

6.1 Installing the service door (accessories)
Model-dependent installation instructions are included with the service door (Dometic SK4, SK5).
NOTE
Prepare the feed-through for the vent hose at the desired location (chapter “Venting the cartridge tank (if a service door is installed only)” on page 28).
6.2 Making wall cutouts

1. If a service door is installed: Follow the instructions of the installation manual that comes with the service door.

2. Select the model-dependent template and place it on the outside of the vehicle.
   The sample template (fig. 2, page 3) greatly reduced in size shows the tank flap (1), the service door (2) and the filling for the service door (3).

3. Make a rectangular opening in the outer wall with the following dimensions (fig. 3, page 4):

If a service door is installed only: Wall cut out for the service door
Service door wall cutout SK4:
–y = 25mm
– b = 305 mm ± 1 mm
–h = 375mm ± 1mm
The dimension x results from the placement of the cassette toilet.
Service door wall cutout SK5:
–ymin = 12.5 mm, ymax = 28 mm
– b = 310 mm ± 1 mm
– h = 360 mm ± 1 mm
The dimension x results from the placement of the cassette toilet.
Model CTW4xxx only: Wall cutout for the tank flap
For the CTW4xxx model, mount a tank flap for the integrated water tank.
➤ Note the instructions in chapter “Installing the tank flap” on page 28.
6.3 Setting up the cassette toilet
NOTICE!
All components of the system must be installed in frost-free areas. In freezing temperatures, there is a risk of damage caused by frost.
NOTE

• When installing the cassette toilet in a wet room, the manufacturer recommends that you connect the cassette toilet to the shower tray.
• The cassette toilet base is equipped with a protruding collar for receiving the upper edge of the shower tray (fig. 4, page 4).

1. Install the cassette toilet according to the description for the respective model version.
2. Set up the cassette toilet so that it is flush to a vertical wall only.
3. Leave enough space so that actuation of the draining slider is not restricted.
4. For the installation, use the dimensional drawings:
   – CT4050, CT(E)4110: fig. 5, page 5
   – CTLP4050, CTLP4110: fig. 6, page 6
   – CTS 4050, CT(E)S4110: fig. 7, page 7
   – CTW4050, CTW4110: fig. 8, page 8

6.4 Installing CT(E)4xxx models
The detached model CT(E)4xxx has no integrated water tank and no console. Set up this model so that the wall behind it can accommodate the control unit of the toilet,
the electrical connections and possibly a water tank. It is best if you put a box in front of the room wall (fig. 9, page 9).
Note here that the cassette protrudes 110 mm out of the cassette housing (fig. 0 a, page 9). The base height is between 50 and 110 mm, depending on model (fig. 0 b, page 9).

1. If a service door is installed: Align the cassette toilet according to the service door.
2. Place the housing base flush with the installation box so that there is a clean transition and no gap

Attaching cassette toilet CT(E)4xxx

1. Place the cassette toilet in the desired position.
2. CT4xxx only: Tightly fasten the base plate with six bolts (4.5 x 45 mm, not included) (fig. a, page 10).
3. Bolt the cassette toilet housing to the wall (using a maximum of 7 bolts, not included) (fig. b, page 10).
4. CT4110 only: Place the two covers over the fastening screws in the base plate (fig. c, page 11).

Installing the control and operating panel of the CT(E)4xxx cassette toilet
Install the control and operating panel in the wall in the immediate vicinity of the cassette toilet at an easily accessible location.
NOTE
Use the scale template to make the wall cutout (fig. d, page 11).

1. Prepare an opening in the installation box for the control and operating panel (fig. e 1, page 12).

2. Connect the electrical cables to the connections of the control and operating panel (chapter “Electrical connection” on page 29).
   CAUTION! There is a risk of injury due to the springs springing back.

3. CT 4xxx only: Press in the retaining springs of the control and operating panel (fig. e 2, page 12).

4. Push the control and operating panel into the wall cutout (fig. e 3, page 12).

5. Follow the instructions in chapter “Connecting the water supply” on page 27.

6. Slide in the mobile tank cassette (fig. f, page 12).

6.5 Installing models CTLP4xxx, CT(E)S4xxx, CTW4xxx
These models have a wall connection console. The control and operating panel is integrated in the wall connection console.
Models CTLP4xxx and CT(E)S4xxx have no water tank, while model CTW4xxx has an integrated water tank.
Setting up cassette toilets CTLP4xxx, CT(E)S4xxx, CTW4xxx
Set up all models with wall connection console directly against the room wall (fig. g, page 13). A previously attached wall bracket is used to secure the cassette toilet and the wall bracket.

1. Screw on the wall bracket, level, at the following height (fig. h, page 13):
   – CTLP4050, CTLP4110: h = 479.5 mm
   – CTS 4050, CT(E)S 4110: h = 651.5 mm
   – CTW4050, CTW4110: h = 651.5 mm

2. Put the entire toilet module into the desired position in front of the wall bracket.

3. Lift the cassette toilet and hook the housing into the wall bracket (fig. g, page 13).

4. Tightly fasten the base plate with six bolts (fig. a, page 10).

5. Slide in the mobile tank cassette (fig. f, page 12).

6.6 Connecting the water supply
NOTICE!

• CT4xxx, CTLP4xxx, CTS4xxx, CTW4xxx only: The water supply is connected using a solenoid valve mounted in the toilet housing (fig.19 1, page 14).
• The operating pressure (water pressure) of the solenoid valve should not exceed 6 bar.
• The solenoid valve is damaged by excessive pressure.

NOTE
For the CTW4xxx models with an integrated water tank, the water connection is installed at the factory.

1. Use a spring band hose clamp to attach the freshwater supply hose to the connection socket (fig.19 2, page 14).
2. Perform a leak test.

6.7 Venting the cartridge tank (if a service door is installed only)

Service door SK4 and SK5

1. In the niche floor, create an opening with a diameter of approx. 12 mm (fig.20, page 14).
2. Run the vent hose into this opening for discharge to the outside.

Service door SK5 (optional)

1. Press the spray paint out of the inner frame of the door (fig. k, page 15).
2. Install the door.
3. Insert the hose of the vent into the integrated vent opening of the service door and the cassette tank (fig. 22, page 15).

6.8 Instaling the tank flap
For the CTW4xxx model, mount a tank flap for the integrated water tank.
Proceed as follows (fig. 23, page 16):

1. Using the template, create an opening in the outer wall.
2. Slide the O-ring onto the inner tube of the tank flap.
3. Grease the O-ring. This makes it easier for the filler neck to be connected with the upper part of the tank.
4. Seal the tank flap watertight (with butyl rubber, for example).
5. Tightly fasten the tank flap with four C4x25 countersunk screws (not included).
6. Perform a leak test.
