General design considerations are:
1. The total distance between the chiller and the
air-cooled condenser must not exceed 200
actual feet or 300 equivalent feet. Keep the
distance as short as possible.
2. Liquid line risers must not exceed 15 feet in
height from the condenser liquid line
connection.
3. Discharge line risers cannot exceed an elevation
difference greater than 100 actual feet without a
minimum of 2% efficiency decrease.
4. To form a proper liquid seal at the condenser,
immediately drop at least 15 inches down from
the liquid outlet before routing the piping to the
chiller. Make the drop leg before any bends or
angles connecting to the remainder of the liquid
connection piping.

Caution: Liquid line sizing for each chiller
capacity are in Table 6. These line sizes are listed
per circuit and apply where leaving water
temperature (LWT) is 40°F or higher. For
applications where the LWT is below 40°F, size
lines using the ASHRAE Refrigeration Handbook
or other suitable design guide.
