P65Wamings.ca.gov <br />NOTES: For use with Trim Chart on page 27 b. <br />General Notes: <br />• Valve must be trimmed as shown. Any deviation from trim size <br />or arrangement may affect the proper operation of the valve. <br />• All pipe, 3/4" (20 mm) and smaller, shall be galvanized steel <br />except when other materials are specified in the technical data <br />for the system used. All trim components must be listed for up <br />to 300 PSI (20.7 bar) Water Working Pressure. <br />• Dimensions in parentheses are millimeter. <br />• Viking uses ASME fitting designations. Tee's shall be called <br />out in the following order: 1 - largest outlet on run; 2 - Smaller <br />outlet on run; 3 - Branch size. <br />NOTE, Viking uses ASME fitting designations. Tee's shall be called out in the following <br />manner, 1-Largest outlet on runj 2-Smaller outlet on runj 3-Branch size, <br />3/4' 1/2' <br />1/2' <br />3/4' <br />3/4' 3/4' <br />! 7k <br />!7 e <br />1/2' 3/4' 1/2' <br />Note 1: When using a water motor alarm, a strainer is required. Circuit closer vent trim may be required when an alarm pressure <br />switch is used. (See technical data for the retard chamber.) <br />Note 2: This location may be used for optional pressure relief valve (not available from Viking). Install 3/4" (20 mm) tee and listed <br />pressure relief valve. <br />Note 3: To supply an optional excess pressure pump (not available from Viking and not a listed assembly), replace'/2' ell marked "A" <br />with a tee. Replace 3/4" ell marked "B" with a tee to connect outlet from excess pressure pump. Do not exceed listed water working <br />pressure rating of system components. Perform hydrostatic tests in accordance with recognized Installation Standards. <br />Note 4: Location for non -interruptible pressure switch. When waterflow through the alarm valve occurs, supply to this location can- <br />not be shut off until water flow through the alarm valve stops. Caution - Non-interuptable alarm port may only be used on systems <br />with constant pressure. A retard chamber may not be installed on the non-interuptable alarm port. <br />Note 5: Component specified is included in Viking trim sets; do not substitute. Use of components other than specified will void any <br />listings and approvals and may affect operation of the valve. <br />Note 6: 300 PSI (20.7 bar) water pressure gauges are provided with trim. 600 PSI (41.4 bar) water pressure gauges are available. <br />Order separately when needed*. Refer to current Viking Price Book. <br />* NFPA 13 requires gauges to have a minimum limit not less than twice the normal water working pressure at the point where the gauges are installed. <br />When normal water working pressure exceeds 150 PSI (10.3 bar), order 600 PSI (41.4 bar) water pressure gauges separately. <br />Form No. F_102993 18.10.18 P65 Replaces Form F_102993 Rev. 14.1 <br />(Added P65 Warning.) <br />
