is evide t, it should be oted o the carrier’s freight bill
a d a claim e tered i accorda ce with the i structio s
give o the advice ote.
Major damage must be reported immediately to your
local Joh so Co trols represe tative.
MOVING THE UNIT
Prior to movi g the u it, e sure that the i stallatio site
is suitable for i stalli g the u it a d is easily capable of
supporti g the weight of the u it a d all associated
services.
The u it should be lifted usi g lifti g lugs a d a
spreader bar or frame of sufficie t width to preve t
damage to the u it from the lifti g chai s.
The u its shall be suitable for elevator or forklift truck
or cra e for co ve ie ce of lifti g. Whe tra sporti g
with a cra e, a ca vas hammock shall be used to come
rou d the u it base a d be faste ed. If the packagi g
box has bee removed, i order to move the machi e,
please apply suitable partitio to protect the surface a d
the side pa el, as show i the picture below. Duri g
the tra sit, the machi e shall be kept i level co ditio
to avoid damagi g the u it due to crude operatio .
Be particularly careful to ensure unit
steady. Pay special attention to the
weight distribution of the unit to avoid
maldistribution and the center of
gravity leans to the side of compressor.
Please try once before hoisting and
observe whether it is tightened and
whether there is any risk of tip-over of
the unit. The hoisting shall be slowly
lifted with constant speed to avoid the
tip-over of the unit and attention shall
be paid to the security of personnel
nearby.

To ensure warranty coverage, this e uipment must be commissioned and serviced by an
authorized YORK service mechanic or a ualified 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 HP cutout settings, design working pressures, and ventilation
re uirements consistent with the amount and type of refrigerant charge.
Lethal voltages exist within the control panels. Before servicing, open and tag all disconnect
switches.
INSPECTION CHECKLIST
The followi g items, 1 through 4, must be checked
before placi g the u its i operatio .
1. The ameplate co te t of the u it is ide tical with
