There's no guard rail to that drop behind the far unit, [yet?]. I take it power and control circuit cables enter within the insulated refrigerant lines? Is it usual to put them both in the same insulating sleeve in the US? Freezing condense? Clearance side and rear looks ok, but I would have mounted the units higher for possible snow entry problems - I see some frost now. Bit exposed there to wind too.
And, is that a gremlin peering out from just below the 'liquidtight' in the foreground?
