Caution!
REFRIGERANT PIPING CONNECTIONS
Refrigerant joints are to be brazed with 15% silver content brazing
alloy, utilizing the NITROGEN BRAZING PROCESS.
NITROGEN BRAZING PROCESS
PURPOSE:
Utilize the NITROGEN BRAZING PROCESS on all brazed refrigerant
piping connections. This process eliminates oxidation products from
inside joint surfaces.
TECHNIQUE:
“Trickle” nitrogen gas at 1-2 psi pressure through the joint area being
brazed, to displace the oxygen. When oxygen has been displaced,
turn off the nitrogen, and relieve the pressure at the joint to
atmospheric prior to brazing.
CONSEQUENCES:
Failure to displace oxygen with nitrogen at the brazed joint will result
in particulate matter being released into the system. The result is
discoloration of refrigerant oil, contamination of the system and
possible system failure.
Compressor units are shipped from the factory with a low pressure nitrogen holding charge. Carefully
relieve the holding charge when the compressor unit is being prepared to connect refrigerant system
piping.
Caution!
This compressor unit is equipped with Copeland Ultra 32-3MAF Polyol
Ester Oil (POE). This is the only brand and type of oil that is
recommended for use with ETI compressor units.
POE oil absorbs significant amounts of moisture from the air very
rapidly. Exposure of the POE oil to air must be minimized. Even a few
minutes of exposure to air can be harmful to the system.
After the initial nitrogen holding charge has been released from the
compressor unit, it is critical that air not be allowed to enter the
compressor unit during the process of preparing compressor unit
refrigerant connections (tube cutting, deburring, cleaning, brazing, etc).
To ensure air does not enter the compressor unit while preparing
refrigerant connections, “trickle” dry nitrogen through the compressor
unit, entering at the access port nearest the Active Charge Control
(ACC), to keep airborne moisture out of the compressor unit and the
POE oil.
Complete preparing and brazing all compressor unit refrigerant
connections at one setting to minimize exposure of open connections
to air. Failure to implement the above precautions will result in an
extended period of time to effectively evacuate the system, and may
adversely affect system performance and cause system failure.

PSC-QS (10/16) Page 12
The compressor unit has factory installed service valves on the earth loop vapor and liquid stubouts
outside the compressor cabinet.

After installing and nitrogen brazing the HVAC system components, turn the Service Valves to Full
Open and pressurize the refrigeration system to 150 psig with dry nitrogen and a trace of refrigerant.
Valve off the nitrogen Tank from the HVAC system components and check joints with a sensitive
Electronic Leak Detector and bubble solution to ensure they are sealed. Repair any leaks and re-test
as appropriate.

PSC-QS (10/16) Page 13
4) System Applications and Electrical
The PSC compressor unit electrical box major components and electric data for all compressor sizes
are shown in Figure 7.
The PSC series compressor units are equipped with a Nano-PLC (Programmable Logic Controller) to
provide a range of functions that enhance the comfort and efficiency of system operation. See the
Appendix detailing the PLC Functions for Air Only Systems.
The SureStart Module is a factory installed component that (1) reduces compressor starting current;
(2) reduces compressor starting torque, thus reducing stress on the compressor at start-up; and (3)
monitors the run capacitor.
The Earth Loop Protection Control System, comprised of the EPS Power Supply, EPS Module and
EPS Fuse is contained within the electric box. This system is factory wired and ready to be connected
to the anode wire through an external electrical connection on the backside of the compressor cabinet.
The anode wire connection is detailed in a later section of this manual.

5) EarthLinked® Diagnostic and Monitoring system (EDM)
The EarthLinked® Diagnostic and Monitoring system (EDM), as shown in Figure 7, provides real-time
remote monitoring and tracks pressures, temperatures, power consumption and thermostat signals. It
connects via Internet, Bluetooth, USB and SD card. The EDM system is factory-installed in all PRIME
series units. Sensors are already connected to respective components and the system will begin
collecting data at unit startup. The EDM system has the ability to send data remotely to the Earthlinked
online Dealer Dashboard when connected to the homeowner’s internet router with an Ethernet cable.
Technicians can also wireless access the EDM data onsite with a Bluetooth connection to a phone or
tablet. For homeowners without Internet access, or as a secondary data backup, the EDM system has
an onboard SD Memory Card Writer that records the time, date, and sensor/signal values that can be
personally graphed or uploaded to the Dealer Dashboard for review.
For more information on the EDM system, refer to the EDM-IOM manual.
6) Air Zoning
Prime series compressor units are compatible with Air Zoning thanks to the Nano-PLC (see Appendix
for more information).
When zoning a forced air system, it is recommended to design the smallest zone of the system so that
it has the air flow capacity to support the minimum airflow requirement of the system (400 CFM /
nominal) while the system is in a second stage without exceeding 1” WC total static pressure across
the Air Handler unit when only that zone calls.
AVV Series Variable Speed Air Handlers should be used in any zoning application.
Bypass dampers between the supply and return plenums should not be used.
In the event that a zone is too small to meet the requirements above, the Air Zoning Option kit (AZO-
KIT) must be purchased and installed. Such a designed zone may in fact never see a second stage
call, which will force the system into a 5 minute second stage maintenance cycle from time to time to
ensure oil return from the field back to the compressor unit.
IMPORTANT!
Failure to meet this requirement can result in shortened blower motor
life, noise issues and can cause performance, efficiency and reliability
issues with the compressor unit itself.

PSC-QS (10/16) Page 20
The Air Zoning Option kit is designed to use the Damper Override “D” terminal signal of the
compressor unit to force open the largest zone while the EarthLinked system is in maintenance mode.
The kit isolates the zone control and air handler power supplies and ensures system performance and
reliability by providing a means of making “R” and “Y” thermostat input of the zone board’s largest
zone. Forcing that zone open relieves excessive static pressure at the air handler.
See Figure 11 for the Field Wiring Diagram of the Air Zoning Option Kit.
Figure 11. Air Zoning Option Kit, Field Wiring Diagram
