IMPOR T ANT : Some of the unit skids are larger than standard door openings. Be sure that the path to the unit’ s final destination is wide enough to accommo- date unit shipping skid. Remove the skid if necessary . If skid is removed and rollers are used, attach rollers to unit tube sheets while moving unit.
F i g .6—T ypical Cooler (30HXA, HXC) and Condenser (30HXC Only) Piping and Wiring NOTES: 1. Wiring and piping shown are for general point-of-connection only and are not intended to show details for specific installation. Certified field wiring and dimensional diagrams are available upon request.
30HXA REFRIGERANT PIPING (See Fig. 7) — T ake care when running the refrigerant piping from the 30HXA unit to the remote condenser(s) to avoid excessive pres- sure drops. The pressure drop using R-134a refrigerant is dif ferent than when using R-22 refrigerant.

NOTES: 1. V alues are for a 2° F pressure drop at 125 F (51.7 C) saturated discharge tem- perature, 120 F (48.9 C) saturated condensing temperature, and 105 F (40.6 C) liquid refrigerant temperature. 2. Size each circuit separately . Fig. 10 — R-134a Discharge Line Sizing, 30HXA Units Fig.
T o install condenser piping: 1. Remove bolts on weld flanges, and remove flanges from condenser water heads. Remove the weld flanges before welding piping to the flanges. Refer to Fig. 1 and 2 for weld flange locations. Failure to remove the flanges may dam- age the sensors and insulation.
