8. Installation, System Processing and Commissioning
Utmost care must be taken while handling the Water-Cooled Scroll
condensing unit. Please go through the contents below to ensure proper
handling.
a. Inspection
Inspect the condensing unit and any accessories shipped with them for
damages or shortages before and during unloading. All items on bill of lading
should be accounted for prior to signing the shipping receipt. Note any
shortages or damage on delivery receipt (specify the extent and type of
damage found). Unit should be inspected carefully for concealed damage.
Notify Emerson sales/application personnel of the damage immediately. Do
not repair the unit until instructed by Emerson’s representative.
The system is shipped with a holding charge of dry nitrogen. Check to see
that pressure is still in the unit upon receipt. Report lack of pressure
immediately to the Emerson’s application/sales representative.
b. Location and Fixing
Generally installed on the top of the cold room to reduce the connection
length between the condensing unit and the evaporator. Enough space to be
provided around the unit for easy service. Also ensure easy access to the unit.
c. Refrigeration Piping Installation
All interconnecting pipes should be of refrigeration grade, clean, dehydrated
and must remain capped at both ends until installation. Even during installa-
tion, if the system is left for any reasonable period (say two hours), pipes
should be re- capped to prevent moisture and contaminants from entering
the system.
Do not assume that the service connection sizes on the unit (at the service
valves) are the correct size to run your interconnecting refrigeration pipes.
The service valve sizes have been selected for convenience of installation and
in some cases (larger units) these may be considered too small. However, for
the very short pipe run within our units, these service connection sizes are
adequate.
The pipe should be sized to ensure optimum performance and proper oil
return. The sizing must also consider the full capacity range through which
this particular unit will need to operate.
16

Pipe runs should be kept as short as possible, using the minimum number of
directional changes. Use large radius bends and avoid trapping of oil and
refrigerant. This is particularly important for the suction line. The suction line
should ideally slope gently towards the unit. Recommendation slope is
1/200~1/250. P traps, double risers and reduced pipe diameters may be
required for suction lines where long vertical risers cannot be avoided. All
pipes should be adequately supported to prevent sagging which can create
oil traps.
The recommended pipe clamp support distance is shown in the table.
d. Refrigerant line insulation
- Insulate suction lines from the evaporators to the condensing unit with
minimum of 1” thickness closed-cell type insulation.
- Long liquid lines run in areas exposed to high temperatures should be fully
insulated with minimum 1/2” insulation.
- Suction and liquid lines should never be taped or soldered together.
e. Electrical
- All electrical work must be done in accordance with the National Electrical
Code and existing local codes.
- Power supply must be the same as specified on the unit’s name plate.
- Voltage fluctuations in excess of 10 percent must be corrected.
- Before starting the unit, ensure that all protective devices are in place
and that all wiring is secure.
f. Brazing Recommendation
Maintain a flow of oxygen-free nitrogen through the system at a very low
pressure during brazing. Nitrogen displaces the air and prevents the forma-
tion of copper oxides in the system. If copper oxidization is allowed to form,
the copper oxide material can later be swept through the system and block
screens such as those protecting capillary tubes, thermal expansion valves,
and accumulator oil return holes. This minimizes any entry of contaminants
and moisture.

- Remove the liquid line connection cap.
- Then remove the suction connection cap.
- Open both valves midway.
- Care should be taken to avoid the holding charge from releasing too
quickly.
- Be sure tube fitting inner diameter and tube outer diameter are clean prior
to assembly.
- Recommended brazing materials: a copper / phosphorous or copper /
phosphorous / silver alloy rod should be used for joining copper to copper
whereas to join dissimilar or ferric metals, use a silver alloy rod, either flux
coated or with a separate.
- Use a double tip torch.
g. Start-up & Operation
Initial pressure test (by vacuum and nitrogen)
Step-by-step
• Use a 4-port gauge manifold with 3/8” hose and connections to the
vacuum pump. The vacuum gauge does not have to be connected for this
part of the process.
• Connect the gauges to service ports provided on receiver valve and suction
tube. In order to remove any non-condensable that may have entered the
system during installation, follow these steps:
• Start the vacuum pump. The evaporator fan should be running and the
compressor crankcase heater is energized at this point. This will involve
powering up the unit so it is important to disconnect the live feed wire to
the compressor contactor (so the compressor cannot run and the crank
case heater can be energized).
• Open both valves on the manifold and then open the main vacuum valve
on the pump. Run the system until the vacuum level of -0.85 bar (as read
on manifold gauge) is achieved.
• Shut off the main vacuum pump valve. Check for vacuum rise using the
manifold compound gauge. A rise would indicate a large leak.
• If vacuum holds for 10 minutes, break vacuum with Nitrogen. Check the
name plate of the unit / compressor for allowable leak test pressure.
Ensure that pressure regulators are installed on the Nitrogen cylinders.
Check for leaks and repair leakage.

Leak Check
The success of all the subsequent commissioning depends on a leak free
system, free of contaminants, free of oxides, free of non-condensable’ s, that
has been evacuated to a low vacuum and charged with the prescribed refrig-
erant.
Leak test is particularly important for field-connected systems. Typically, field
systems lose as much as 20%–30% of their refrigeration charge annually. This
is not only an unnecessary expense but also damages the environment. Com-
pressor oil can be lost at the same time as refrigerant and eventually lead to
compressor failure. (Time spent on leak test will eventually reduce the time
spent on the evacuation process).
Ensure that all service valves are open during the leak test process. It is
important to recheck all joints within the unit as well as the external joints.

leak free.
b. Ensure that the test pressure do not exceed the system design pressures.
c. Do not expose system pressure control LP to test pressures above the
design pressure. This can damage the pressure controls.
d. Using an approved, calibrated electronic gas leak detector, leak test the
entire system paying attention to all joints (you might have to charge
small quantity of refrigerant before charging the Nitrogen to enable this
procedure).
e. Periodically check functionality of the electronic leak detector during this
process.
f. To further check system integrity, spray a soapy water solution over joins
then visually inspect for bubbles.
g. Leave the system under pressure for a designated period (24 Hours).
h. Check and record the ambient temperatures and the system pressure with
calibrated approved instruments. This process is to be carried out every
8-12 hours during the pressure testing process.
i. If the test pressures cannot be maintained, repeat the leak testing process
employing the isolation of sections of the system to determine the source
of leaks. Repair the leak and repeat the leak testing process until system
can be signed off as leak free and approved by authorized personnel.
j. Record findings and confirm pressure testing process completion.

Evacuation
a. After the system is leak checked, connect approved dual stage vacuum
pump sized to application with preferably fresh oil to evacuate the system.
b. Ensure all inline system shut-off valves and solenoid valves are fully open.
c. Evacuate the system to 300 microns.
d. A triple evacuation is recommended in case of using analog gauges as we
might not know the exact vacuum level being achieved
Charging and commissioning
Reminder
- The scroll compressor design requires system charging with liquid
refrigerant into the liquid line.
- Do not vapor charge the Water Cooled Scroll unit. After ensuring all valves
are opened and system is evacuated properly, only then start the
refrigerant charging process. Also ensure that LP cutout is not by-passed
during the charging process.
Step-by-step:
1. Ensure that there is no power supply to the Water Cooled Scroll unit.
The liquid line solenoid needs to be kept open for the charging process and
this may require a temporary power feed to it.
2. Connect the refrigerant cylinder to main service hose and purge line at
the manifold end.
3. Ensure correct orientation of the refrigerant cylinder. Follow cylinder
labeling/instructions so that liquid refrigerant can be charged into the
system. This will be charged through the high-pressure side of the manifold
and Water Cooled Scroll unit liquid service valve. Ensure that at least 70-80%
of the required refrigerant charging is done by this method.
4. The compressor can then be started, and the unit continued to be
charged (with the controlled liquid refrigerant through the suction service
valve). The quantity of charge should always be measured. See note.
5. The system needs to be operated down to its design evaporating tem-
perature before you can be sure the charge is correct. It is at this point that
the normal refrigeration operational checks can be carried out - such as
checking the liquid line sight glass for bubbles and the operating pressures.
Refrigerant charging is regarded full/complete when the operating tempera-
ture of the system has been stable for some time and the liquid line sight
glass is clear.
