Wiring the LCR
General
Once the LCR, and optional equipment such as control valve and ETVC kit have been installed in accordance with
instructions supplied with the units, wiring connections need to be made from those components to the LCR. The user
supplied wiring for all connected equipment must be routed through suitable conduit to the LCR. Threaded pipe
conduit, Liquid Tight, and Synflex are among some choices. If plastic Synflex fittings are used, make sure that they are
rated for outdoor use, temperature and gas/oil service. The conduit hubs on the LCR are all 1/2” - 14 NPT. Recommended
conduit routings are shown to the right. For your convenience in wiring, all terminal blocks on the LCR are removable
by pulling straight up. CAUTION: The conduit/cable entrances must be sealed inside and out using appropriate cable
glands to prevent moisture from entering in the LCR.
