PRE--START--UP
PERSONAL INJURY HAZARD
Failure to follow this warning could result in personal
injury or death.
!
WARNING
1. Follow recognized safety practices and wear
approved Personal Protective Equipment (PPE),
including safety glasses and gloves when
checking or servicing refrigerant system.
2. Do not use a torch to remove any component.
System contains oil and refrigerant under
pressure. To remove a component, wear PPE
and proceed as follows:
a. Shut off all electrical power to unit.
Apply applicable Lock--out/Tagout
procedures.
b. Recover refrigerant to relieve all
pressure from system using both
high--pressure and low pressure ports.
c. Do not use a torch. Cut component
connection tubing with tubing cutter
and remove component from unit.
d. Carefully un--sweat remaining tubing
stubs when necessary. Oil can ignite
when exposed to torch flame.
3. Do not operate compressor or provide any
electric power to unit unless compressor
terminal cover is in place and secured.
4. Do not remove compressor terminal cover until
all electrical power is disconnected and
approved Lock--out/Tagout procedures are in
place.
5. Relieve all pressure from system before
touching or disturbing anything inside terminal
box whenever refrigerant leak is suspected
around compressor terminals.
6. Never attempt to repair a soldered connection
while refrigerant system is under pressure.
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
The unit must be electrically grounded in accordance
with local codes and NEC ANSI/NFPA 70 (American
National Standards Institute/National fire Protection
Association.
!
WARNING
Proceed as follows to inspect and prepare the unit for
initial start--up:
1. Remove all access panels.
2. Read and follow instructions on all WARNING,
CAUTION, and INFORMATION labels attached to,
or shipped with, unit.
3. Make the following inspections:
a. Inspect for shipping and handling damages
such as broken lines, loose parts, or discon-
nected wires, etc.
b. Inspect for oil at all refrigerant tubing con-
nections and on unit base. Detecting oil
generally indicates a refrigerant leak. Leak--
test all refrigerant tubing connections using
electronic leak detector, halide torch, or li-
quid--soap solution.
c. Inspect all field--wiring and factory--wiring
connections. Be sure that connections are
completed and tight. Be sure that wires are
not in contact with refrigerant tubing or
sharp edges.
d. Inspect coil fins. If damaged during ship-
ping and handling, carefully straighten fins
with a fin comb.
4. Verify the following conditions:
a. Make sure that condenser--fan blade are
correctly positioned in fan orifice. See
Condenser--Fan Adjustment section for
more details.
b. Make sure that air filter(s) is in place.
c. Make sure that condensate drain trap is
filled with water to ensure proper drainage.
d. Make sure that all tools and miscellaneous
loose parts have been removed.
START--UP, GENERAL
Unit Preparation
Make sure that unit has been installed in accordance with
installation instructions and applicable codes.
IMPORTANT
: Follow the base unit’s start-up sequence
as described in the unit’s installation instructions:
In addition to the base unit start-up, there are a few steps
needed to properly start-up the controls. RTU-OPEN’s
Service Test function should be used to assist in the base
unit start-up and also allows verification of output
operation. Controller configuration is also part of start-up.
This is especially important when field accessories have
been added to the unit. The factory pre-configures options
installed at the factory. There may also be additional
installation steps or inspection required during the start-up
process.
Additional Installation/Inspection
Inspect the field installed accessories for proper
installation, making note of which ones do or do not
require configuration changes. Inspect the RTU-OPEN’s
Alarms for initial insight to any potential issues. Refer to
the following manual:
“Controls, Start--up, Operation and
Troubleshooting Instructions.”
Inspect the SAT sensor for
relocation as intended during installation. Inspect special
wiring as directed below.
