PRODUCT DESIGN

GSZ/VSZ13 models are available in 1 1/2 through 5 ton sizes and use R-410A refrigerant. They are designed for 208/230 volt single phase applications.

Select GSZ13 models are available in 208/230 and 460 volt 3-phase applications. These models use R-410A refrigerant.

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. GSZ 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.

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.

RECOMMENDED

GSZ/VSZ models use high-efficiency Copeland® scroll "Ultratech" compressors which are specifically desgined for R-410A refrigerant. There are a number of design character- istics which are different from the scroll compared to the tra- ditional reciprocating compressor.

"Ultratech" Series scroll compressors with Copeland® ComfortAlert diagnositics will not have a discharge thermo-

stat. Some of the early model scroll compressors required discharge 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.
