10 — Field Power Wiring Connections FIELD CONTROL WIRING - Install a Carrier-approved accessory thermostat assembly according to the installation instructions included with the accessory. Locate thermostat assembly on a solid wall in the conditioned space to sense average temperature. Route thermostat cable or equivalent single leads of no. 18 AWG (American Wire Gage) colored wire from subbase terminals through conduit in unit to low-voltage connections as shown on unit label wiring diagram an

Remember to reconfigure the chiller for each feature selected (see Table 13). For temperature reset, demand limit, and dual set point, desired set points must be entered through keypad and display module (see Set Point Function section on page 39). See Table 17 for overall troubleshooting information.

1 - 09BB012 Air-Cooled Condenser . Receiving the Unit - Inspect unit for shipping damage. Enter any claims directly with the transportation company. Carrier Air Conditioning Company will not be responsible for damage incurred in transit. Uncrating - Remove unit and hardware from shipping skid. Check to see that unit and component parts conform to the bill of lading. Contents of fastener package are listed in Table 1. Before Installation - Check space requirements, service clearances, floor st

They may be located in any area having unobstructed air circulation; the low silhouette permits installation in varied ground or roof locations. Each unit consists of a direct drive motor (or motors), fan (or fans), fan guards, motor mounts, condenser coil with integral subcooling circuit, wind deflector, and electrical junction box. Weather Armor* enclosures (which are also provided for 09DC016) have a baked enamel finish which provides maximum weather protection. Capacities 15 Tons and Over

For example, in Table 2, add .67 x 10 lbs (4.5 kg) (approximately 6.7 lbs [3.0 kg]) for the 67% circuit. Refer to Table 6 for condenser coil refrigerant circuit data. Check Operation of Condenser Fan Motor Controls and Rotation of Fans — Rotation should be clockwise as viewed from top of unit. A CAUTION To prevent personal injury, be sure wire fan guards are secured in place over each fan before starting the unit. IMPORTANT. Check for proper fan rotation (clockwise viewed from above). If rot

This instruction book will fulfill normal requirements. Additional information may be obtained by application to Carrier Machinery and Systems Division Service Supervisor in the nearest district office. Special attention should be given to precautionary instructions emphasized in this book to avoid start-up difficulties. These precautions are, in general, applicable to all sizes of 17DA centrifugal refrigeration machines. Instructions for the prime mover if not in-cludeçl with Carrier Air Cond

Loosen the compressor holddown bolts to allow free spring travel. Open the compressor suction and discharge service valves. Check that oil is visible in the compressor sight glass.

Willis Carrier invented centrifugal refrigeration in 1922 and today, more than half a century and 25,000 machines later, Carrier hermetic centrifugal liquid chillers still lead the way in comfort air conditioning and process cooling. What’s more, the modern day 19 Series centrifugals are specifically designed to afford significant dollar savings on utility bills, in every way possible. The Carrier 19 Series centrifugal design philosophy has always been to offer a variable line which meets each
