BlockIng for Safety

Mounting the Anti Tipping Device – Figures 8 – 11

WARNING!

• The anti tipping bracket must be mounted to prevent the appliance from tipping when the fully stocked door is opened.
• Be sure that there is no plumbing or electrical wiring located in this area which screws or drills could damage.

The anti tipping bracket is provided with the appliance.

1. Mark the center line of the appliance on the back wall. Align the anti tipping bracket center to this line.
2.  Depending on the constitution of the floor and wall, use any possible mounting option as shown in Figures 8 – 11.

IMPORTANT
The anti tipping bracket must be fitted at the same height as the toe kick area. If you set the appliance to a higher level by laying spacers underneath, the anti tipping bracket must be fitted accordingly.

Mounting Options
Mounting the bracket with the wall stud.
Mounting with wall plugs to concrete walls (Figure 8).

Mounting with the wall plate turning in the screws at an angle (Figure 9).

Mounting with wooden floors (Figure 10).

Mounting with concrete floors using the anchors provided (Figure 11).

Mounting the Anti Tipping Device in Cabinets deeper than 24″ – Figures 12 – 13
A proper function of the anti tipping bracket is warrantedwithin a cabinet depth of between 24″ and 25″. If the cabinet is deeper than 25″, a wooden spacer must be mounted between appliance and wall.
WARNING!
Be sure the wooden spacer is fastened securely to the floor.
Measuring for mounting the wooden spacer on inset kitchen cabinets – Figure 12

Measuring for mounting the wooden spacer on frameless kitchen cabinets – Figure 13

IMPORTANT
If the floor slopes down sideways, the anti tipping bracket must be fitted horizontally. Lay down spacers in the appropriate positions.

Cover Strips – Figure 14
Apply cover strips above, between and below the securing plates on the side walls of the appliance.
Cut the cover strips to the length shown in Figure 14.

Fit the adhesive cover strips leaving a gap of 1/4″ to each securing plate.
This ensures problem-free fitting of the covers.

Icemaker

Safety Instructions and Warnings

• Do not install the water connection while the combined refrigerator-freezer is connected to an electrical outlet.
• The connection to the water supply may only be made by a trained and licensed plumber.
• All equipment and devices used to supply the water to the appliance must comply with the current regulations for your geographical area.

WARNING!
Connect to potable water supply only.

Water Connection Requirements

• The water supply pressure requirements are different based on whether or not the supplied Liebherr water filter is installed.
  With the filter installed, the pressure must be in the range of 40-90 psi (2.8-6.2 bar).
  Without the filter installed, the acceptable pressure range is 22-87 psi (1.5-6 bar).
  Failure to meet these requirements will likely result in ice maker malfunction and possibly cause a water leakage that can damage flooring and surrounding furniture.
• A shut-off valve, must be installed between the hose line and the main water supply so the water supply can be stopped if necessary.

IMPORTANT
Do not install the shut-off valve behind the appliance.

Water Connection Adapter – Figure 15
IMPORTANT
Only use the supplied adapter for connection to the solenoid valve. The solenoid valve has a metric R3/4 male connector. Any attempt to use other adapters for connection could damage the thread on the solenoid valve.
The supplied adapter enables different connection options for different kinds of water lines. A water line is not supplied with the appliance.

IMPORTANT
Do not use any old or already premounted water supply lines.

The connection to the valve connector can be done with or without the angle connector, as required.
Braided style ice maker hoses can be connected directly to the threaded ends.
For connection with 1/4″ OD copper lines, use the union nut with compression ring.

IMPORTANT
Make sure that the connection is fitted with a seal and is tight.

• Insert the water strainer supplied into the valve connector (Figure 16).

Connection to the Water Supply

1. Move the appliance towards the final position and leave enough space to work behind.
2. Insert the water supply line into its intended opening at the back of the appliance (F i gure 17).
   Back view of appliance bottom left
3. Move the power supply line to the area of the electrical outlet.
   WARNING!
   Do not connect to the electrical outlet before the installation is completed and the water line is connected to the solenoid valve.
4. Move the appliance slowly into the recess until the appliance back slides into the anti tipping bracket (Figure 18).
5. Remove the cover from the solenoid valve (Figure 19).
6. Connect the water line to the adapter in the respective configuration, depending on the type of water line used. Figure 19 shows the configuration with a copper line as an example.
7. Bleed the air from the water line by opening the water supply temporarily.
8. Screw the adapter onto the solenoid valve (Figure 20).
9. Open the shut-off valve for the water supply and check the entire water system for leaks.

CAUTION!
Power cord/Water line trapped between anti-tipping device andrear of the appliance. Power cord/Water line crushed. Install cable holders. Insert power cord/water line in cable holders.
IMPORTANT
These steps are only necessary if the electrical outlet or water line are on the opposite side.

Install the cable holders on the rear of the appliance. Insert power cord/water line in cable holders.
Slide the appliance into the recess. To avoid damage, pull the power cord and water line backwards at the same time with slight tension.

IMPORTANT
After sliding the appliance into the recess, plug in the appliance and check its function. Then unplug it again.
