PRODUCT DESIGN
4
DSZ18 models are available in 3, 4 and 5 ton sizes and
use R-410A refrigerant. They are designed for 208/230 volt
singlephaseapplications.
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
areofthe sweat type for field piping withrefrigeranttypecop-
per. Front seating valves are factory installed to accept the
fieldruncopper. The total refrigerantcharge for a normal in-
stallationis factory installedinthecondensingunit. DSZ units
are charged for the matching evaporator coil and a 15 foot
refrigerantlineset.
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.
DSZmodels use high-efficiencyCopeland®scroll "Ultratech"
compressorswhichare specifically desgined for R-410Are-
frigerant.Thereare a number ofdesigncharacteristicswhich
aredifferentfromthescrollcomparedtothetraditionalrecip-
rocatingcompressor.
"Ultratech" Series scroll compressors with Copeland®
ComfortAlert diagnostics will not have a discharge thermo-
stat. Some of the early model scroll compressors required
dischargethermostats.
Due to their design Scroll compressors are inherently more
tolerantofsmall quantities of liquid refrigerant.
NOTE: Eventhough the compressorsectionofaScroll com-
pressor is more tolerant of liquid refrigerant, continued
floodback or flooded start conditions may wash oil from the
bearingsurfacescausing premature bearing failure.
"Ultratech" Series scroll compressors use "POE" or
polyolesteroil whichisNOT compatiblewithmineraloilbased
lubricants like 3GS. "POE" oil must be used if additional oil
isrequired.
WARNING
To avoid possible injury, explosion or death, practice
safe handling of refrigerants.
Operating pressures and amp draws may differ from stan-
dardreciprocatingand/orscroll 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
andother objects.
NOTE: This unit cannot be completely enclosed. At least
one side must be unrestricted.
Theseclearanceswillhelpavoidairrecirculation.Ifinstalling
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:
* Directlyundera vent termination fora gas appliance.
* Within 3 feet of a clothes drier vent
* Wheretherefreezingofdefrostwaterwould create
ahazard
* Where water may rise into the unit.

NOTE: This data is provided as a guide, it is important to electrically connect the unit and properly size fuses/circuit breakers and
wires in accordance with all national and/or local electrical codes. Use copper wire only.
Unit specifications are subject to change without notice. ALWAYS refer to the unit's serial plate for the most up-to-date general
and electrical information.
DSZ180361A* -DSZ180601A*
* Up to 24' in equivalent line length
(1) Wire size should be determined in accordance with National Electrical Codes; extensive wire runs will require larger wire sizes.
(2) Maximum Overcurrent Protection Device: MUST use Time Delay Fuse or HACR type Circuit Breaker of the same size as noted.
NOTES:
• Always check the S & R plate for electrical data on the unit being installed.
• Installer will need to supply 7/8" to 1-1/8" adapters for suction line connections (4 & 5 ton units).
• Installer will need to supply 3/4" to 7/8" adapters for suction line connections (3 ton unit).
• Unit is charged with refrigerant for 15' of 3/8" liquid line. System charge must be adjusted per Installation Instructions Final Charge
Procedure.
• Installation of these units requires the specified TXV Kit to be installed on the indoor coil. THE SPECIFIED TXV IS DETERMINED BY THE
OUTDOORUNIT,NOTTHEINDOORCOIL.

SPLIT SYSTEM HEATING PERFORMANCE
High pressure is measured at the suction service valve ( the larger valve). AMPS = Outdoor unit amps (comp.+fan)
Low pressure is measured at the gauge port connection. KW = Total system power
Calculations are based on nominal CFM and 70 °F indoor dry bulb.
