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
Variable water flow control kit PWFCKN000 is required for applications with entering
water temperatures below 590F (one kit per frame). Minimum flow rate must be 40% of
the nominal flow rate, 2-10V signal with a linear flow response valve.
3
Sound pressure levels are tested in an anechoic chamber under ISO 3745 standard
at rated AHRI operating conditions. Sound pressure level may increase during heating op-
eration at maximum compressor frequency. Value in parenthesis is the maximum sound
pressure at those conditions.
4
Value is calculated as follows: Δt = Total Heat of Rejection ÷ (Rated Flow Rate x 500).
Data is for pure water.
5
Communication cable between WSU, IDU(s) / HRU(s), and Central Controller must be a
minimum of 2-conductor, 18 AWG, twisted, stranded, and shielded. Ensure the
communication cable shield is properly grounded to the WSU chassis only. Do not
ground the communication cable at any other point. Wiring must comply with all applica-
ble local and national codes.
6
Power wiring is field provided, solid or stranded, and must comply with the applicable
local and national codes.
7
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.
