RT-SVX055D-EN 21
Note: The Copeland SSA scroll compressors for R-410A
units use Trane OIL00094. The correct Oil for Trane
CSHD is Trane OIL00079 or OIL00080. Compressor
types are listed in Table 3, p. 21. The appropriate oil
charge is list
ed in Table 4, p. 21.

2. After the compressor and condenser fan have started
and operated for approximately 30 minutes, observe
the operating pressures. Compare the operating
pressures to the operating pressure curve in the
Service Facts.
3. Check system subcoo
ling. Foll
ow the instruction listed
on the subcooling charging curve in the Service Facts.
4. Repeat Step 1 through Step 3 for each refrigerant
circuit.
5. To stop the SERVICE TEST, turn the
main power
disconnect switch to the “Off” position or proceed to
the next component start-up procedure. Remove
electro mechanical test mode connections (if
applicable).
Heating Start-Up
1. Clamp an amp meter around one of 1
st
stage heater
power wires at the heater contactor.
2. Verify that the heater stag
e is operat
ing properly.
3. Clamp an amp meter around one of 2
nd
stage heater
power wires at the heater contactor (if applicable).
4. Verify that the heater stage is operat
ing properly.
5. To stop the SERVICE TEST, turn
the main power
disconnect switch to the “Off” position or proceed to
the next component start-up procedure. Remove
electro mechanical test mode connections.
Final System Set Up
After completing all of the pre-start and start-up
procedures outlined in the previous sections (i.e.,
operating the unit in each of its modes through all
available stages of cooling and heating), perform these
final checks before leaving the unit:
• Program the Night Setback (NSB) panel (if applic
able)
for proper unoccupied operation. Refer to the
programming instructions for the specific panel.
• Verify that the Remote panel “System”
selection
switch, “Fan” selection switch, and “Zone
Temperature” settings for automatic operation are
correct.
• Inspect the unit for misplaced tools, hardware, and
debris
.
• Ve
rify that all exterior pan
els in
cluding the control
panel doors and condenser grilles are secured in place.
• Close the main disconnect switch or circuit protector
switch th
at provides the supply power to the unit’s
terminal block or the unit mounted disconnect switch.
