13 Step 6 — Fill the Chilled W ater Loop W A TER SYSTEM CLEANING — P r o pe r wa t e r sy s t em cleaning is of vital importance. Excessive particulates in the water system can cause excessive pump seal wear , reduce or stop flow , and cause damage of other com ponents.
14 Ensure the following when filling the system: 1. Remove temporary bypass piping and cleaning/flushing equipment. 2. Check to make sure all drain plugs are installed. 3. Open the blow-down valve to flush the strainer . Normally , a closed system needs to be filled only once.
15 EXAMPLE: Supply voltage is 240-3-60. AB = 243 v BC = 236 v AC = 238 v A verage V oltage = 243 + 236 + 238 3 = 239 v Determine maximum deviation from average voltage: (AB) 243 – 239 = 4 v (BC) 239 – 236 = 3 v (AC) 239 – 238 = 1 v Maximum deviation is 4 v .
