Installing the Solar Heating System Interface Kit
(Optional, Sold Separately by LG; Model No. PHLLA; For Those Applications With A Third-Party Solar Heating System)
• Always shut the power off before installing the accessories There is a risk of electric shock, physical injury and / or death.
• Never operate the Hydro Kit outside of the operational parameters as outlined in this manual and the product specifications. There is a
risk of electric shock, fire, physical injury and / or death.
• Never touch wiring or install the sensor with wet hands. There is a risk of electric shock, physical injury and / or death.
• Never operate the Hydro Kit outside of the operational parameters as outlined in this manual and the product specifications. There is a
risk of product malfunction and / or damage.
• Ensure the sensor cable has a proper routing path; the sensor cable path must be at least two (2) inches away from any power wiring.
Depending on the current draw of nearby wiring, the minimum clearance distance will have to be increased. For more information regarding
power wiring / communications cable clearances, see the Wiring section.
Refer to the figure below when installing the Solar Heating System Interface Kit. For more detailed information, see the Solar Heating System
Interface Kit Installation Manual for specific installation procedures.
1. Check the diameter of the pre-installed pipes (A and B).
2. If the diameter of the pre-installed pipes is different from diameter of solar heating kit, it is necessary to reduce or increase the diameter of
the pipe.
3. Connect the pipe and solar heating system interface kit.
4. If a water tank sensor is already connected to CN-TH4 on the Hydro Kit PCB, disconnect it first, and then connect the solar heating sensor
to CN-TH4.
CN-TH4 connection can be used with either the Indirect Water Storage Tank Sensor OR the Solar Heating System Interface Kit with its sensor. Both
accessories CANNOT be connected to CH-TH4 at the same time.
Solar Heating System Sensor and Well (Included with Solar Heating System Interface Kit Model No. PHLLA [but sold
separately from the Hydro Kit])
Install the solar heating system well, sensor, and sensor cable similar to the procedure for the indirect water storage tank sensor (see the
previous pages and the Wiring section.
