property damage.
• Consider ambient conditions (temperature, direct sunlight, inclem-
ent weather, etc.) when selecting, installing, and connecting the

will lead to product malfunction.
Hydro Kits include many factory-provided accessories, as well
as can be used with optional LG-manufactured accessories (sold
separately), and field-supplied third-party accessories. Systems that
include Hydro Kits can vary greatly, so follow the design engineer's
requirements, manufacturers' specifications, as well as local, state,
and federal codes when installing any accessory.
• Check each accessory carefully before installing.
• Verify the labels on the Hydro Kit PCB and terminal block before
connecting all accessory wiring / cables.
• Field-supplied third-party thermostats, valves, and pumps must
follow LG Hydro Kit system requirements. Follow manufacturers'
installation instructions.
• See the guidelines for installing an LG supplied dry contact in the
manual that shipped with the dry contact.
• When connecting a pump to the Hydro Kit system, select a suitable
relay for pump capacity. Use a 208-230V pump with a maximum operation current of 4A or less.
