Hello all, I Just got a new Hayward 140k btu heat pump today and brought it to my equipment pad only to find out the pad is pitched to the front putting the heater an inch out of level from back to front. The pad is 4'x8' and 6" thick with the pool plumbing coming up through it so leveling that is out of the question. Does anyone know if the unit can be shimmed in the front or does the entire bottom have to sit on a solid base? Worse case I can build a pressure treated platform. Was hoping someone my have encountered this. Thanks.
