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.

T erminals TB2-1 1 and TB2-12 are provided for field in- stallation of a chilled water (fluid) pump interlock (CWPI) and a chilled water (fluid) flow switch (CWFS). These de- vices are to be installed in series. Contacts must be rated for day circuit applications capable of handling a 24-vac to 50 mA load.
30HXC UNITS — The 30HXC units are shipped from the factory with a full charge of R-134a. Unit should not need to be charged at installation unless a leak was detected in Step 6 — Leak T est Unit section on page 26.
