SCWD-QS (12/16) Page 11
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!
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.
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.

SCWD-QS (12/16) Page 12
The compressor unit package contains a service valve kit and an adapter kit. The two service
valves are to be installed on the earth loop vapor and liquid connections of the compressor
unit, using the adapters to right-size to the proper earth loop line set.
Installation of the service valves will provide isolation of the earth loop system from the compressor
unit and provide easy access to the refrigerant system.
For the installation of system components requiring refrigeration connections, refer to Figure 5 for line
set sizes and the appropriate installation manual(s) following Figure 5.

After installing and nitrogen brazing the HVAC system components and compressor unit service
valves, 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.

SCWD-QS (12/16) Page 13
4) System Applications and Electrical
The SCWD compressor unit electrical box major components and electric data for all compressor
sizes are shown in Figure 6.
The SureStart Module is an optional 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 electrical diagrams that follow include the
SureStart.
For compressor unit electrical diagrams that do not include SureStart, see the Appendix A.
The SCWD 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
Appendix B detailing the Nano-PLC functions for the hydronic heating and cooling systems.
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.
SCWD Heating and Cooling System electrical and application illustrations are as follows.

5) SureStart
Features
SureStart is an optional factory installed soft starter that reduces light flicker caused at start-up by
scroll compressor motors. This control has the following features:
60 to 70% reduction in direct in-rush current
Under voltage protection
Motor reversal protection
Self-adjusts for optimal start performance
50/60 Hz compatible
ETL, CE, EMC and RoHs compliant
Tolerant to “dirty power” conditions
Fault LED
Internal current limiting
Run capacitor monitoring
SureStart is factory wired for the appropriate power supply.
Operation
When the system control calls for compression operation, the compressor contactor will energize. If
the supply voltage is less than “minimum start-up voltage”, a 50 second delay is initiated. At the end
of the delay, another attempt will be made to start the compressor unless the supply voltage remains
unchanged. See Figure 11 for the SureStart Mode of Operation.
SureStart uses an optimated starting process that learns the starting characteristics of the
compressor to further refine the starting cycle on each recurring start.
If the compressor fails to start, the module will terminate the start attempt after 1 second and initiate a
3 minute lockout before attempting a restart.
While the compressor is running, if supply voltage falls below the “shutdown on low voltage” limit for 2
seconds, SureStart will stop the compressor and initiate a 3 minute lockout. A restart will be initiated
after 3 minutes if the supply voltage is equal to or greater than the “minimum startup voltage”. This is
done to protect the compressor against a sudden drop in supply voltage.
SureStart is able to detect an interruption in power, when the interruption is 0.1 seconds or longer.
When a power interruption is detected, it will shut down the compressor for 3 minutes. A power
interruption that is shorter than 0.1 seconds may result in the compressor running backwards.
SureStart is able to determine if the compressor is running backwards. If this condition is detected,
the control will stop the compressor for 3 minutes before restart is initiated.
If the run capacitor is faulty or has failed, SureStart will shut down the compressor for 3 minutes
before initiating a restart.
