3. Make the following inspections:
a. Inspect for shipping and handling damages such
as broken lines, loose parts, or disconnected
wires, etc.
b. Inspect for oil at all refrigerant tubing connec-
tions and on unit base. Detecting oil generally
indicates a refrigerant leak. Leak−test all refrig-
erant tubing connections using electronic leak
detector, halide torch, or liquid−soap solution.
c. Inspect all field−wiring and factory−wiring con-
nections. 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 shipping 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.

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.
