NOTE: CKF**-*P* units are shipped without refrigerant and

are pressurized with a nitrogen holding charge. This

charge must be removed and unit evacuated and charged as

per the installation instructions.

The United States Environmental Protection Agency (“EPA”) has issued various regulations re-

garding the introduction and disposal of refrigerants introduced into this unit. Failure to follow

these regulations may harm the environment and can lead to the imposition of substantial fines.

These regulations may vary by jurisdiction. Should questions arise, contact your local EPA office.

PRODUCT DESIGN

CKF 50 Hz models are available in 2 through 6 ton sizes.

They are designed for 220/240 to 380 volt single phase appli-

cations.

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.

NOT

RECOMMENDED

OK!

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. Back 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. CKF units

are charged for the matching evaporator coil and a 15 foot [5 m]

refrigerant line set.

OK!

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.

CKF condensing units use a mix of Copeland Reciprocating^®

and Copeland Compliant^®Scroll compressors. There are a

number of design characteristics which are different from the

scroll compared to the traditional reciprocating compressor.

Measurements in inches. [ ] Designates metric equivalents.

NOTE: Even though the compressor section of a Scroll com-

pressor is more tolerant of liquid refrigerant, continued flood-

back or flooded start conditions may wash oil from the bear-

ing surfaces causing premature bearing failure.

Copeland Compliant^®Scroll compressors use white oil which

is compatible with 3GS. 3GS oil may be used if additional oil

is required.

Special consideration must be given to location of the con-

densing unit(s) in regard to structures, obstructions, other

units, and any/all other factors that may interfere with air

circulation. Where possible, the top of the unit should be

completely unobstructed; however, if vertical conditions re-

quire placement beneath an obstruction there should be a

minimum of 60 in. [152 cm] between the top of the unit

The CKF condensers use new generation scroll compres- and the obstruction(s). The specified dimensions meet re-

quirements for air circulation only. Consult all appropriate regu-

latory codes prior to determining final clearances.

sors. These compressors have an internal equalization mecha-

nism and an anti-counter rotation device which allow the scrolls

to equalize in approximately ½ second at shut down.

Another important consideration in selecting a location for

the unit(s) is the angle to obstructions. Either side adjacent

the valves can be placed toward the structure provided the

side away from the structure maintains minimum service clear-

ance. Corner installations are strongly discouraged.

Operating pressures, amp draws and minimum circuit am-

pacity may differ from standard reciprocating compressors.

This information may be found in the "Cooling Performance

Data" section and should be reviewed prior to installation of

the condenser.

DO NOT locate the unit:

–

Directly under a vent termination for a gas appliance.

Within 3 feet [1 m] of a clothes dryer vent.

Where the refreezing of defrost water would create a

hazard.

–

Where water may rise into the unit.

CKF**-*P* models are shipped with a nitrogen holding charge only.

Wire size should be determined in accordance with National Electrical Codes. Extensive wire runs will require larger wire sizes.

May use fuses or HACR-type circuit breakers of the same size as noted.

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.

PERFORMANCE DATA

PERFORMANCE TEST

All data based upon listed indoor dry bulb temperature. .00 inches external static pressure on coil of outdoor section. Indoor

air cubic feet per minute (CFM) as listed in the Performance Data Sheets:

If conditions vary from this, results will change as follows:

1. As indoor dry bulb temperatures increase, a slight increase will occur in indoor air temperature drop (Delta T). Low and

high side pressures and power will not change.

2. As indoor CFM decreases, a slight increase will occur in indoor temperature drop (Delta T). A slight decrease will

occur in low and high side pressures and power.

A properly operating unit should be within plus or minus 2 degrees of the subcooling value shown in the installation

instructions.

A properly operating unit should be within plus or minus 3 degrees of the typical (Delta T) value shown.

A properly operating unit should be within plus or minus 10 PSIG of the HI PR shown.

A properly operating unit should be within plus or minus 5 PSIG of the LO PR shown.

A properly operating unit should be within plus or minus 3 Amps of the typical value shown.
