evaporator. Condenser installations more than 10 feet below the evaporator are not recommended.
Insulation of liquid lines is not required but can be useful in preventing condensation from forming
and to avoid fl ashing on long pipe runs.
2.1.3 Suction Lines
Some applications call for the compressor to be mounted as part of the condenser, more commonly
referred to as a condensing unit. Such require fi eld piping of liquid and suction lines. Suction lines
are trapped similarly to discharge lines. Common practice for suction line selection and installation
should be followed. Suction lines should always be insulated.
2.1.4 Connection Sizes, Air Cooled Units
MODEL HOT GAS LINE LIQUID LINE SUCTION LINE
DAMA-01 1/2” 1/2” 3/4”
DAMA-1.5 1/2” 1/2” 3/4”
DAMA-02 1/2” 1/2” 3/4”
DAMA-2.5 1/2” 1/2” 3/4”
Note: Units will have a liquid line and either a hot gas or suction line
Field connections at the indoor evaporator and remote condenser or condensing unit will
not necessarily be the same as the fi eld pipe size required. In some cases these sizes will
vary signifi cantly.
