of this manual.
Note: On units with 3-phase power supplies, ensure the 3 phases are connected in the
correct rotation ie L1, L2, L3. If the phase rotation is incorrect, the compressor will fail
to pump and will likely be noisy. If this is the case, two phases will need to be
swapped over to achieve correct rotation.
