PRODUCT DESIGN
DSX16 models are available in 2, 3 4 and 5 ton sizes and
use R-410A refrigerant. They are designed for 208/230 volt
single phase applications.
The condenser air is pulled through the condenser coil by a
direct drive propeller fan. This condenser air is then dis-
charged out of the top of the cabinet.
These units are designed for free air discharge, so no addi-
tional resistance like duct work shall be attached.
The suction and liquid line connections on present models
are of the sweat type for field piping with refrigerant type cop-
per. Front seating valves are factory installed to accept the
field run copper. The total refrigerant charge for a normal in-
stallation is factory installed in the condensing unit.DSX units
are charged for the matching evaporator coil and a 15 foot
refrigerant line set.
Systems should be properly sized by heat gain and loss
calculations made according to methods of the Air Condi-
tioning Contractors Association (ACCA) or equivalent. It is
the contractors responsibility to ensure the system has ad-
equate capacity to heat or cool the conditioned space.
DSX16 models use the Copeland Scroll "Ultratech" Series
compressors which are specifically designed for R-410A re-
frigerant. There are a number of design characteristics which
are different from the traditional reciprocating and/or scroll
compressors.
"Ultratech" Series scroll compressors with Copeland
ComfortAlert diagnostics will not have a discharge thermo-
stat, some of the early model scroll compressors required
discharge thermostats.
"Ultratech" Series scroll compressors will not have a dis-
charge thermo-stat. Some of the early model scroll compres-
sors requireddischarge thermostats. Due to their design Scroll
compressors are inherently more tolerant of small quantities
of liquid refrigerant.
NOTE: Even though the compressor section of a Scroll com-
pressor is more tolerant of liquid refrigerant, continued
floodback or flooded start conditions may wash oil from the
bearing surfaces causing premature bearing failure.
"Ultratech" Series scroll compressors use "POE" or
polyolester oil which is NOT compatible with mineral oil based
lubricants like 3GS. "POE" oil must be used if additional oil
is required.
WARNING
To avoid possible injury, explosion or death, practice
safe handling of refrigerants.
Operating pressures and amp draws may differ from stan-
dard reciprocating and/or scroll compressors. This informa-
tion may be found in the "Cooling Performance Data" sec-
tion.

This unit is for outdoor installation only. Refer to minimum
figure for clearances from the sides of the unit to full walls
and other objects.
NOTE: This unit cannot be completely enclosed. At least
one side must be unrestricted.
These clearances will help avoid air recirculation. If installing
two or more units at the same location, allow at least 24
inches between units. If only one side is restricted (for ex-
ample, against the outside wall of a house), the unit may be
placed as close as 8" to that one wall.
DO NOT locate the unit:
* Directly under a vent termination for a gas appliance.
* Within 3 feet of a clothes drier vent
* Where the refreezing of defrost water would create
a hazard
* Where water may rise into the unit.
