NOTE: Units will have a liquid line and either a hot gas (condenser) or suction line (condensing unit).
Note: Field connections at the indoor evaporator and remote condenser or condensing
unit will not necessarily be the same as the eld pipe size required. In some cases
these will vary signicantly.
