Rated capacity is certified under AHRI Standard 1230. Ratings are subject to change without notice.
Current certified ratings are available at www.ahridirectory.org.
2
Power wiring is field provided, solid or stranded, and must comply with the applicable local and national
codes.
3
Sound pressure levels are tested in an anechoic chamber under ISO 3745 standard.
4
LG requires that LATS software be used on all projects to ensure correct line sizing. Designer must
verify the shop drawing design against the as built design using LATS. Contractor must also use LG
manufactured Y-Branch and Header Kits only.
5
Variable water flow control kit (PRVC1) is required for all entering water temperatures (one kit per
frame). If entering water temperatures fall below 42°F, glycol must be added to the system.
6
Value is calculated as follows: Δt = Total Heat of Rejection/(Nominal Flow Rate x 500).
7
Communication cable between WSU to IDUs to be 18 AWG, 2-conductor, twisted, stranded, shielded.
Ensure the communication cable shield is properly grounded to the WSU chassis only.
Do not
ground the WSU to IDUs communication cable at any other point. Wiring must comply with all ap-
plicable local and national codes.

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%.
