Plumbing Requirements

The PRO 48 has an automatic ice maker with an integrated water filtration system. The water supply line should be located within the shaded area shown in the illustrations.

The water line must not interfere with installation of the anti-tip bracket.

The water supply line should be connected to the house supply with an easily accessible shut-off valve between the supply and the unit. Do not use self-piercing valves.

A saddle valve kit is available through your authorized

Sub-Zero dealer.

A reverse osmosis system can be used, provided there is constant water pressure of 20 psi (1.4 bar) to 120 psi

(8.3 bar) supplied to the unit at all times. In this application, the water filtration system must be bypassed. Refer to water filter bypass mode on page 16.

IMPORTANT NOTE: All installations must meet local plumbing code requirements.

It is not recommended that the ice maker be connected to a softened water supply. Water softener chemicals, such as salt from a malfunctioning softener, can damage the ice maker and lead to poor ice quality. If a softened water supply cannot be avoided, make sure that the water softener is well maintained and operating properly.

IMPORTANT NOTE: Do not use with water that is microbiologically unsafe or of unknown water quality without adequate disinfection before or after the system. Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts.

Anti-Tip Bracket Installation

To prevent the PRO 48 from tipping forward and provide a stable installation, the unit must be secured in place with the anti-tip bracket provided with the unit.

IMPORTANT NOTE: Placement of the anti-tip bracket is critical to a stable installation. Failure to properly position the anti-tip bracket will prevent it from engaging the unit.

The anti-tip bracket must be installed exactly 26" (660) from the front of the face frame of the unit to the back of the anti-tip bracket. Also, the centering line on the lower flange of the anti-tip bracket must be centered in the rough opening. Make sure the anti-tip bracket is installed on a solid base. Refer to the illustration below.

To properly secure the anti-tip bracket for a stable installation, use all anti-tip bracket hardware as instructed for wood or concrete floors.

IMPORTANT NOTE: For either wood or concrete floor applications, if the wood screws do not hit a wall stud in any of the upper holes on the anti-tip bracket, use the provided #8–18 x 1 1 /

4

" wood screw, #12 flat washer and nylon zip-it wall anchor in its place.

IMPORTANT NOTE: In some installations the subflooring or finished floor may necessitate angling the screws used to fasten the anti-tip bracket to the back wall.

Make sure there are no electrical wires or plumbing in the area which the screws could penetrate.
