23 Installation I. DELIVER Y INS PECTION Vilter screw c ompressor compone nts are thor - oughly inspected at the factor y , as suring the shipmen t of a mechanically pe r fect piece of equip- men t. Damage can occur in shipme nt, howev er . For this re ason, the units should be thoroughly inspected upon arrival.
24 Installation Care must be take n to avoid trapping the line s e x - ce pt for s peci fi c purposes. Whe n traps are used, the horiz ontal dimensions should be as short as possible to a void exce ssive oil trapping. Lines f or ammonia systems mu st be of steel pipe with speci ally designed ammonia service fi ttings.
25 These precautions will av oid costly dam age to the equipmen t due to freezing. This inf ormation is take n from A SHRAE 15-89 and ANS I B31.5. The inst alling c ontrac tor should be thoroughly familiar with the se codes, as w ell as any local c odes.
26 valves on the lo west par t of the syst em so the ga s will fl o at away from the c ompressor . This pre- ve nts any dir t or f oreign par ticles from e ntering the compres sor and contamina ting the working par ts. The oil should the n be charged int o the compres sor .
27 T o begin the second evacu ation, allow the pump to oper ate and reduce the pressure ag ain to within 50 to 1000 microns. After this reading is reac hed, allow the pump to operat e 2 or 3 hour s. St op the pump and let the system stand with this vacuum.
28 Af te r the system is leak -free and evacuation h as been c ompleted, it is ready f or charging. Be fore actual charging, ho wever , the entire ope ration of the refrige ration syste m should be inspec ted as outlined be low: A. Low Side E quipment 1.
29 should show no bubbles, and there will be a liquid seal in the rec eive r . If these t wo c ondi - tions are not satis fi ed, additional re frigerant must be added. 5 . Whe n sufficient re frigerant ha s been char ged into the syste m, close the ch arging and drum valves.
