9 Table 2 — Water Quality Guideline s LEGEND *Heat exchanger materials considered are copper, cupronick e l, 304 SS (stainless steel), 316 SS, titanium. †Closed recirculating system is identified by a closed pressurized piping system. **Recirculating open wells should observe the open recirculating design considerations.
10 Example: Supply voltage is 460-3-60. AB = 452 volts BC = 464 volts AC = 455 volts Determine maximum deviation from average voltage: (AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v Maximum deviation is 7 v . Determine percent voltage imbalance.

40 Table 17 — Antifr eeze Percentages by Volume Cooling T ower/Boiler Systems — These syste ms typically use a common loop maintained at 60 to 90 F . The use of a closed circuit evaporative cooling tower with a secondary heat exchanger between the tower and the water loop is recom- mended.
41 when the heat pump software is downloaded to the board. Oc- cupancy types are described in the scheduling section below . The following sections describe the functionality of the WSHP Open multi-protocol controller .
42 After a compressor is staged off, it may be restarted again after a normal time-guard period of 5 minutes and if the supply-air temperature has increased above the minimum supply-air temperature limit. The WSHP Open controller provides a status input to moni- tor the compressor operation.
43 The control has four user adjustable set points: DCV start control set point, DCV maximum control set point, minimum damper position, and DCV maxim um damper position.

45 Aquazone™ Deluxe D Contr ol LED Indica- tors — There are 3 LED indicators on the Deluxe D control. See T able 20. ST A TU S L ED — S tatus LED indicates the current status or mode of the Deluxe D control. The Status LED light is green. TE S T L ED — T est LED will be activated any time the De- luxe D control is in test mode.
46 Clean condensers with an inhibited hydrochloric acid solu- tion. The acid can stain hands and clothing, damage concrete, and, without inhibitor , damage steel. Cover surroundings to guard against splashing. V apors from vent pipe are not harmful, but take care to prevent liquid from being carried over by the gases.
47 TROUBLESHOO TING When troubleshooting problems with a WSHP , consider the cuases and solutions in T able 21. Thermistor — A thermistor may be required for single- phase units where starting the unit is a problem due to low voltage.
