Insulation
Additional housing, refrigerant and condensate pipe insulation has been supplemented to prevent sweating
while operating if the Hydro Kit unit installed in abnormal environmental conditions. (Optional - job condition
specific.)
All refrigerant and chilled water pipes are independently insulated. All insulation seams and joints are airtight.
Insulation is not compressed. Double layer insulation is provided at pipe supports and wall penetrations.
Electrical
Power provided is single phase, ±10% of indoor unit nameplate specifications.
Power wires properly sized and protected per NEC and local codes. Indoor unit is properly grounded.
Power and communications conductors are separated by the recommended minimum distance.
Terminal block screws are tight. Power wires are not in contact with terminals (3(A) and / or 4(B). Line voltage
wires have spade connectors installed.
Power wires are properly secured to the control box case to prevent wire tension at the terminal block.
Wires are protected from chaffing at control box and conduit pipe penetrations.
Low voltage control cables are properly secured to the control panel case. Terminal block screws are tight and
the cable is protected from sharp edges at control box case and conduit openings.
Cables are installed at recommended distances from high voltage and EMF generating equipment.
Communications cable between the outdoor (water source) unit and the Hydro kit is terminated at terminals
tagged (terminals 3[A] and 4[B]).
Field provided communications cable is 18-2 stranded and shielded. All terminations are made at the terminal
block. No inline splices or wire caps are present. Spade or ring connectors containing copper are used on all
communications and low voltage cable terminations.
Communications cable insulation material is accepted by local code enforcement.
Communications cable shield is tied back, continuous between the Hydro Kits and the other indoor units and is
grounded at the outdoor (water source) unit only.
Hydro Kit Wall Mounted Controller Communications
LG factory provided Hydro Kit Wall Mounted Controller stranded, shielded (white jacket) cable was used
between the Hydro Kit Wall Mounted Controller(s) and indoor unit(s).
Hydro Kit Wall Mounted Controller cable has not been cut, spliced, or tied together with wire caps. Factory
plugs are present.
Cable is securely plugged into the socket on the Hydro Kit Wall Mounted Controller or the three screw terminals
on the Hydro Kit Unit Controller.; Yellow to "Y", Red to "R", and Black to "B".
Hydro Kit Control Panel
Hydro Kit Wall Mounted Controller cable is securely plugged into the CN-REMO socket on the
Hydro Kit main PCB.
If an optional remote temperature sensor was installed, the associated cable is plugged into socket CN-ROOM.
Hydro Kit unit DIP switches have been adjusted for application (group control-master/slave; water heating
only, etc.)
Wiring harness "Plug C" has been properly connected to either "Plug A" or "Plug B" based on the type of
thermostat and/or room sensor was installed.
All wiring harness connections have been checked and are securely connected to the plug sockets.
Power and communications cables are properly restrained and separated.
Due to our policy of continuous product innovation, some specifications may change without notification.
