J. STARTUP AND OPERATION
J.1. Final Inspection
J.1.1. Check for Refrigerant Leaks
Inspect the unit for any damage to the coils and
tubing that could cause a leak.
J.1.2. Check Level of Unit
Refer to
Section C.6.2.
for setting/checking the
level of the unit.
J.1.3. Check Electrical Connections
For Proper Torque
Use an Inch Pound rated torque wrench to
ensure proper torque. DO NOT CONFUSE
THIS WITH A FOOT POUND RATED WRENCH,
Damage will occur.
Recommended torques for securing wiring:
• To the contactor: 40 in-lb.
• From the T-stat to the control board: 8.0 in-lb.
Figure J.1.3. – A: Where to Wire for Thermostat
J.1.4. Check Control Cables For
Proper Connection
Verify all cables are seated and connected in the
unit as some might come loose during shipping
and transport.
J.1.5. Check For Gas Leaks
Double Check for any gas leaks on the installed
piping. Refer to
Section G.2.3.
for more
information.
J.1.6. Check Filter Installation
Verify that filters are seated and oriented
correctly in the unit as some might come
displaced during shipping and transport. Refer
to
Section D.3.
for more information on filters
and filter installation.
J.1.7. Check Condensate Drain
installation
Verify the Condesate Drain Trap is a minium
of 3 inches deep, plus the Blower Fan Static
Pressure. Verify the Outlet of the drain trap
is a minimum of 3 inches below the outlet of
the drain pan. Ensure the outlet of the trap is
routed to a suitable drain location as required
by local code. Refer to
Section C.5
and
Figure
C.5.1
– A for more information.
J.1.8. Check Blower Compartment
for Accessories
Open all compartments to ensure there are
no tools or other misc parts remaining in the
unit from setup. This is most important on the
blower section to avoid damage to the blower
assembly.
J.2. Turning on Power for the
First time
J.2.1. Checking for Proper 3-Phase
Voltage
Verify that proper power has been supplied to
the unit. This is critical for correct operation of
the compressor.
J.2.2. Check For Proper Phase
Verify that the compressor is running correctly.
J.2.2.1. Standard Blower Rotation
As a reminder, all units with a belt drive
motor may run backwards if the unit is wired
incorrectly. See
Section E.3.4. Checking
Phase and Motor Rotation
for more
information.
J.2.2.2. VFD Blower Rotation
As a reminder, all units with VFD driven blower
motor will have the correct rotation even if
the phase to the unit is wired incorrectly. See
Section E.3.4.1. Checking Phase with VFD
Drive
for more information.
J.2.3. Checking Low (Control) Voltage
Use a voltmeter to measure the low voltage
and low voltage amp draws during operation.
Accessories such as remote smoke detectors
and excessive wire length can increase the amp
draw on the low voltage wiring. Verify that the
total amp draw on the 24Vac side is less than
0.3A in full operation. Refer to
figure F. – A
for
proper low voltage wire lengths.
