Sub-Zero PRO 48 PRO 48 Installation Guide - Page 7

PRO 48 Site Preparation 7 subzero.com/specs 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 illustration. 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 35 psi (2.4 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. A copper line is not recommended for this application. 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.
