NOTE: These units are not suitable for unprotected outdoor use. Carrier recommends that these units be located in the base- ment or on the ground floor. However, if it is necessary to lo- cate the unit on an upper floor, be sure the structure has been designed to support the unit weight. - Page 8 a30-4997...
- Page 9 Units should be installed using certified drawings. 3. All wiring must comply with applicable local and national codes. 4. All piping must follow standard piping techniques. Refer to Carrier System Design Manual part 3, Carrier E20-II software Refrigerant 09DP...
- Page 10 (not neces- sarily the connection size), especially on cooling tower applica- tions. See Carrier System Design Manual, Part 3, Piping Design. See Fig. 11 for condenser pressure drops. Set water regulating valve, if installed, to maintain design head pressure.

Freezing damage caused by an improperly cleaned system represents abuse and may impair or otherwise negatively affect the Carrier product warranty. 1. Install a temporary bypass around the chiller to avoid cir- culating dirty water and particulates into the pump pack- age and chiller during the flush. -
Page 14: Step 7 - Make Electrical Connections
Set Water Flow Rate — Once the system is cleaned, pressur- ized, and filled, the flow rate through the chiller needs to be established. NOTE: Carrier recommends a differential pressure gage when measuring pressures across the pumps or balancing valves. This provides for greater accuracy and reduces error build-up that often occurs when subtracting pressures made by different gages. - Page 15 EXAMPLE: Supply voltage is 240-3-60. AB = 243 v BC = 236 v AC = 238 v 243 + 236 + 238 Average Voltage = = 239 v Determine maximum deviation from average voltage: (AB) 243 – 239 = 4 v (BC) 239 –...
