Start-up
To protect warranty, this equipment
must be installed and serviced by an
authorized YORK service mechanic or
a qualified service person experienced
in air handling and condenser unit
installation. Installation must comply
with all applicable codes, particularly
in regard to electrical wiring and other
safety elements such as relief valves,
HP cut-out settings, design working
pressures and ventilation require-
ments consistent with the amount and
type of refrigerant charge.
Lethal voltages exist within the Con-
trol Panel. Before servicing, open and
tag all disconnect switches.
CHECKING THE SYSTEM PRIOR TO INITIAL START
(NO POWER)
Unit Checks
1. Inspect the unit for shipping or installation dam-
age.
2. Visually check for refrigerant piping leaks.
3. The compressor oil level should be monitored and
maintained so that an oil level is visible in the sight
glass. When compressor is not running, he oil level
should be near the top the sight glass. When the
compressor is running, only a "froth" will be vis-
ible.
4. Check the control panel to assure it is free of foreign
material (wires, metal chips, etc.).
5. Visually inspect field wiring (power and control).
Wiring MUST meet N.E.C. and local codes.
6. Check tightness of terminal lugs inside the power
panel on both sides of the contactors, overloads,
fuses, and power connections.
7. Verify fuse sizing in main circuits.
8. Verify field wiring for thermostat (if applicable),
optional zone sensor, and optional CO

10. Verify all applicable pneumatic tubing has been field
installed for duct static pressure transducers (VAV
units) and optional building pressure transducer for
power exhaust option.
