JOHNSON CONTROLS
FORM NO.: 6U6K-B01E-NB-EN
SECTION 4 – INSTALLATION
To ensure warranty coverage, this equipment
must be commissioned and serviced by an
authorized YORK service mechanic or a qualified
service person experienced in unit installation.
Installation must comply with all applicable codes,
particularly in regard to electrical wiring and other
safety elements such as relief valves, HP cutout
settings, design working pressures, and ventilation
requirements consistent with the amount and type of
refrigerant charge.
Lethal voltages exist within the control panels.
Before servicing, open and tag all disconnect
switches.
INSTALLATION CHECKLIST
The following items, 1 through 5, must be checked before
placing the units in operation.
1.Inspect the unit for shipping damage.
2.Rig unit using spreader bars.
3.Open the unit only to install water piping system. Do not
remove protective covers from water connections until piping is
ready for attachment. Check water piping to ensure cleanliness.
4.Pipe unit using good piping practice.
5.Check to see that the unit is installed and operated within
limitations (
Refer to Operational Limitations
).
The following pages outline detailed procedures to be followed
to install and start-up the unit.
HANDLING
These units are shipped as completely assembled units
containing full operating charge, and care should be taken to
avoid damage due to rough handling.
INSPECTION
Immediately upon receiving the unit, it should be inspected for
possible damage which may have occurred during transit. If
damage is evident, it should be noted in the carrier’s freight bill.
A written request for inspection by the carrier’s agent should be
made at once.
LOCATION AND CLEARANCES
These units are designed for outdoor installations on ground
level, rooftop, or besides a building. Location should be
selected for minimum sun exposure and away from boiler
flues and other sources of airborne chemicals that could attack
the ambient coils and steel parts of the unit. The units must
be installed with sufficient clearances for air entrance to the
condenser coil to ensure adequate supply of fresh air, for air
discharge away from the condenser, and for servicing access.
In installations where winter operation is intended and snow
accumulations are expected, additional height must be provided
to prevent ice accretion in base frame of the unit.
Clearances are listed under “Notes” in the Dimensions section.
The clearances recommended are nominal for the safe and
efficient operation and maintenance of the unit and power and
control panels. Local Health and safety regulations, or practical
considerations for service replacement of large components,
may require larger clearances than those given in this manual.
Foundation
The unit should be mounted on a flat and level foundation, floor,
or rooftop capable of supporting the entire operating weight of
the equipment. See PHYSICAL DATA for operating weight.
If the unit is elevated beyond the normal reach of service
personnel, a suitable catwalk must be capable of supporting
service personnel, their equipment, and the compressors.
Ground Level Locations
It is important that the units be installed on a substantial
base that will not settle. A one piece concrete slab with
footers extended below the frost line is highly recommended.
Additionally, the slab should not be tied to the main building
foundations as noise and vibration may be transmitted.
Mounting holes are provided in the steel channel for bolting the
unit to its foundation (see
Dimensions
section).
