WARNING

SYSTEM CONTAMINANT S, IMPROPER SERVICE PROCEDU RE AND/OR PHYSICAL

ABUSE AFFECTING HE RMETIC COMPRESSOR ELECTRI CAL TERMINALS MAY CAUSE DANGEROUS SYSTEM VENTING.

The successful development of hermetically sealed refrigeration compressors has completely sealed the compressor's moving parts and electric motor inside a common housing, minimizing refrigerant leaks and the hazards sometimes associated with moving belts, pulleys or couplings.

Fundamental to the design of hermetic compressors is a method whereby electrical current is transmitted to the compressor motor through terminal conductors which pass through the compressor housing wall. These terminals are sealed in a dielectric material which insulates them from the housing and maintains the pressure tight integrity of the hermetic compressor. The terminals and their dielectric embedment are strongly constructed, but are vulnerable to careless compressor installation or maintenance procedures and equally vulnerable to internal electrical short circuits caused by excessive system contaminants.

O AVOID POSSIBLE INJURY, EXPLOSION OR DEATH, PRACTICE SAFE

HANDLING OF REFRIGERANTS.

In either of these instances, an electrical short between the terminal and the compressor housing may result in the loss of integrity between the terminal and its dielectric embedment. This loss may cause the terminals to be expelled, thereby venting the vaporous and liquid contents of the compressor housing and system.

A venting compressor terminal normally presents no danger to anyone, providing the terminal protective cover is properly in place.

If, however, the terminal protective cover is not properly in place, a venting terminal may discharge a combination of

(a ) hot lubricating oil and refrigerant (b ) flammable mixture (if system is contaminated

with air)

in a stream of spray which may be dangerous to anyone in the vicinity. Death or serious bodily injury could occur.

Under no circumstances is a hermetic compressor to be electrically energized and/or operated without having the terminal protective cover properly in place.

See Service Section S-17 for proper servicing.

LOCATION & CLEARANCES

NOTE: To ensure proper condensate drainage, unit must be installed in a level position.

In installations where the unit is installed above ground level and not serviceable from the ground (Example: Roof Top installations) the installer must provide a service platform for the service person with rails or guards in accordance with local codes or ordinances.

WALL

UNIT

36"

NOTE: Roof overhang should be no more than 36" and provisions made to deflect the warm discharge air out from the overhang.

Minimum clearances are required to avoid air recirculation and keep the unit operating at peak efficiency.

WARNING

TO PREVENT PO SSIBLE DAMAG E, THE UNIT SHOUL D REMAIN IN AN UPRIGHT POSITION DURING ALL RIGGING AND MOVING OPERA TIONS. TO FACILIT A TE LIFTING AND M OVING IF A CRANE IS USED, PLACE THE UNIT IN AN ADEQUATE CABLE SLIDE.

Refer to Roof Curb Installation Instructions for proper curb installation. Curbing must be installed in compliance with the National Roofing Contractors Association Manual.

Lower unit carefully onto roof mounting curb. While rigging unit, center of gravity will cause condenser end to be lower than supply air end.

Roof Curb and Platform

DP[13-14]CH/DP[13-14]HH**41*

DPCH/DPHH Package Units are designed for outdoor installations only in either residential or light commercial applications.

NOTE: To ensure proper condensate drainage, unit must be installed in a level position.

The connecting ductwork (Supply and Return) can be connected for horizontal discharge airflow. In the down discharge applications, a matching Platform/Roof Curb (PCCP) and Downflow Plenum (PCP101-103) is recommended for horizontal models only.

A return air filter must be installed behind the return air grille(s) or provision must be made for a filter in an accessible location within the return air duct. The minimum filter area should not be less than those sizes listed in the Specification Section. Under no circumstances should the unit be operated without return air filters.

A 3/4" - 14 NPT drain connector is provided for removal of condensate water from the indoor coil. In order to provide proper condensate flow, do not reduce the drain line size.

Refrigerant flow control is achieved by use of restrictor orifices. These models use the FasTest Access Fitting System, with a saddle that is either soldered to the suction and liquid lines or is fastened with a locking nut to the access fitting box (core) and then screwed into the saddle. Do not remove the core

from the saddle until the refrigerant charge has been removed. Failure to do so could result in property damage or personal injury.

The single phase units use permanent split capacitors (PSC) design compressors. Starting components are therefore not required. A low MFD run capacitor assists the compressor to start and remains in the circuit during operation.

The outdoor fan motors are single phase capacitor type motors.

PRODUCT DESIGN

Air for condensing (cooling) is drawn through the outdoor coil by a propeller fan, and is discharged vertically out the top of the unit. The outdoor coil is designed for .0 static. No additional restriction (ductwork) shall be applied.

Conditioned air is drawn through the filter(s), field installed, across the evaporator coil and back into the conditioned space by the indoor blower.

COMPRESSORS

Some DPCH/DPHH series package units use the Compliant Scroll compressor, instead of traditional reciprocating compressors. Still other models use reciprocating compressors.

A scroll is an involute spiral which, when matched with a mating scroll form as shown, generates a series of crescent shaped gas pockets between the two members.

During compression, one scroll remains stationary (fixed scroll) while the other form (orbiting scroll) is allowed to orbit (but not rotate) around the first form.

NOTE: Operating pressures and amp draws may differ from standard reciprocating compressors. This information can be found in the unit's Technical Information Manual.

INDOOR BLOWER MOTOR

Some DPCH/DPHH model package units use a EEM blower motor while others use the standard PSC type blower motor. The EEM motor is a 3 Phase brushless DC (single phase AC input), ball bearing construction motor with an integral control module with an internal FCC B EMI filter.

The EEM motor is continuously powered with line voltage. The switched 24 volt control signal is controlled by the thermostat in the cooling and heat pump mode and the blower relay in the electric heat mode.

ELECTRICAL WIRING

The units are designed for operation at the voltages and hertz as shown on the rating plate. All internal wiring is complete. Ensure the power supply to the compressor contactor is brought to the unit as shown on the supplied unit wiring diagram. The 24V wiring must be connected between the unit control panel and the room thermostat.

As this motion occurs, the pockets between the two forms are slowly pushed to the center of the two scrolls while simultaneously being reduced in volume. When the pocket reaches the center of the scroll form, the gas, which is now at a high pressure, is discharged out of a port located at the center.

During compression, several pockets are being compressed simultaneously, resulting in a very smooth process. Both the suction process (outer portion of the scroll members) and the discharge process (inner portion) are continuous.

Some design characteristics of the Compliant Scroll compressor are:

• Compliant Scroll compressors are more tolerant of liquid refrigerant.

NOTE: Even though the compressor section of a Scroll compressor is more tolerant of liquid refrigerant, continued floodback or flooded start conditions may wash oil from the bearing surfaces causing premature bearing failure.

• Compliant Scroll compressors use "POE" or polyolester oil, which is NOT compatible with mineral oil based lubricant like 3GS. "POE" oil must be used if additional oil is required.

• Compliant scroll compressors perform "quiet" shutdowns that allow the compressor to restart immediately without the need for a time delay. This compressor will restart even if the system has not equalized.
