4~'5 <br /> <br />1505 In systems exceeding 20 pounds c~.pacity, the compressor, if not located under <br />stairways or near dumb Uraiter or elevator shafts; sha.11 be looted as nearly beneath <br />the riser e.s practicable; shall preferably not be in a room containing storage of <br />combustible ma.teria.l; shall in any case be located a.t least 10 feet from such storage; <br />shall be loca.tked in an accessible part of the building witY~ adequate light ing facility <br />provided; and shall be protected. against mecranical injury by anon-combustible <br />partition, or by heavy metal netting secured ~o metal posts. <br />1507 Shut-off valves shall be installed at each service outlet in pressure a.nd <br />rsturn lines, a.nd in each riser or maniford connection at or near the compressor. <br />These valves shall be fitted ~~rith a hand wheel or other means of ready operation as <br />a.n in+.egral part thereof. <br />Valves in sP,rV1CP, connections shall be located outside of refrigerating <br />units and at such distance above the floor as Twill provide ready acr,essibil.ity. <br />Evaporators Trrhich may be removed as a unit sra,ll have valves permitting the <br />removal of the evaporator ~,rith valves attached: <br />108 SERVICE CG?1TI~IECTIONS. <br />(a) Not more than a single tenant shall be supplied from an outlet box on <br />amain riser, Such outlet box shall be locs.ted +,~ithin the premises of the tenant <br />served and so arranged as to be accessible at a]_1 times. <br />(b) No outlet or junction box eha11 be permitted in any hall+aay, sta.irwa.y <br />or vertical shaft not cut off at each story. <br />(c) Every refrigerator sha1.1 be rigidly secured in place. <br />1509 Every system containing over 2(:~ pounds of refrigerant ~~Thich operates above <br />tmospheric pressure, and every Tfra,ter cooled system containing over 12 pounds of re- <br />frigerant and capable of producing a pressure in excess of the test pressure shall be <br />provided ~,~ith a oressure limiting device. <br />1510 Eacr. system containing; over l00 pounds of refrigerant, shall hs;ve compressor <br />protected by apressure-relief valve connected into the high pressure aide betareen the <br />main stop-valve a,nd the cor.~pressor or generator to relieve excessive ~oressure into the <br />1o+,.r pressure side of the system or to the atmosphere. Tr7here discharge is to the lour <br />pressure side, a relief valve shall be provided on the ]_ow pressure side of the system. <br />1 1.1 P1o stop-valve shall be located bet+r~een a pressure relief device, or pressure <br />limiting device and the part of the system protected thereby, unless t,,uo pressure relief <br />devices of required size are used, and so arranged. th~?.t only one pressure relief device <br />can be cut off for repair. purposes at any one time. <br />1 12 Systems exceeding 20 ,pounds capacity shall have a. pressure relief device on <br />she]_]_ type a.ppara.tus, such as liquid separators, liquid receivers, condensers, eva- <br />porators and absorbers ~~rhich can be shut off by stop-valves. <br />1 1 Every system containing more than 100 pounds of refrigerant shall be provided <br />with ahand-operated relief for disch?rging the refrigerant in case of fire, either to <br />the atmosphere or to a suitable body of ura,ter. For syster:s containing irritant or <br />f la.mma.ble refrigerants, the discharge to the ?tmosphere shall be through a proper <br />d. if fuser above the roof of buildings within.°50 feet. The hand-operated relief valve <br />shall be located outside the machinery room, or shall be capable of operation from the <br />outside. <br />1511+ A rupture member may be substituted for the relief, valve in carbon diozide <br />systems or systems operating below atr.:ospheric pressure. <br />. ,Part .16: , <br />P~IATCHE S <br />1001 N o person shall manufacture. trans~ocrt, store or sell matches exceed..ing <br />in aggregate 50 m-.tchmans gross (11s,~+00 matches e;.ch gross) +,~ithout securing a permit <br />from the Chief of the Bureau of Fire Brevention. <br />1102 Application for permit shall be made in trriting and shall set forth in detail <br />location of proposed store or place of sale, or method of transportation; character <br />of building construction, lec~,tion of storage or place of sale orithin the building, kind <br />of matches involved and type of containers. If, after an ins~oection of premises, the <br />provisions of this ordinance are found to have been complied ~~ith, permit shall be <br />issued. <br />1603- '~rtholesale storage.- At <<rholesa.7.e establishments and T~rherever matches exceeding <br />
