Current certified ratings are available at www.ahridirectory.org.
Power wiring is field provided, solid or stranded, and must comply with the applicable local and national
2
codes.
Sound pressure levels are tested in an anechoic chamber under ISO 3745 standard.

verify the shop drawing design against the as built design using LATS. Contractor must also use LG
manufactured Y-Branch and Header Kits only.

MCA = Minimum Circuit Ampacity.
MOP = Maximum Overcurrent Protection is calculated as follows: (Largest motor FLA x 2.25) + (Sum of other motor FLA) rounded down to the nearest standard fuse size.
Allowable voltage range is between 208–230 volts only (tolerance is 10%).
Maximum allowable voltage imbalance is 2%.

Variable water flow control kit (PRVC1) is required for all entering water temperatures (one kit per
5
frame). If entering water temperatures fall below 42°F, glycol must be added to the system.
Value is calculated as follows: Δt = Total Heat of Rejection/(Nominal Flow Rate x 500).

Ensure the communication cable shield is properly grounded to the WSU chassis only.
ground the WSU to IDUs communication cable at any other point. Wiring must comply with all ap-
plicable local and national codes.
