4 INSTALLATION
4.1 Location
YR units are furnished with vibration isolator mounts for
basement or ground level installations. Units may be
located on upper floor levels providing the floor is
capable of supporting the total unit operating weight and
optional spring isolators are used.
Sufficient clearance to facilitate normal service and
maintenance work must be provided all around and
above the unit and particularly space provided at either
end to permit cleaning or replacement of evaporator and
condenser tubes. (See CLEARANCES).
A doorway or other sufficiently large opening properly
located may be used. The chiller should be located in an
indoor location where temperatures range from 4°C to
43°C.
4.2 Foundation
A level floor, mounting pad or foundation must be
provided by others, capable of supporting the operating
weight of the unit.
4.3 Clearances
Clearances should be adhered to as follows:
Rear and above unit – 610 mm.
Front of unit – 915 mm.
Tube Removal – see table below
4.4 Rigging Unit to Final Location
Rig the unit to its final location on the floor or mounting
pad, lift the unit (or shell assembly) by means of an
overhead lift and lower the unit to its mounting position.
(If optional shipping skids are used, remove them before
lowering the chiller to its mounting position.)
At this point units shipped dismantled should
be assembled under the supervision of a York
representative.
If the evaporator is to be field insulated, the insulation
should be applied to the evaporator before the unit is
placed in position while the unit is in the lift position. Be
sure the unit is properly supported. (See INSULATION).
4.5 Locating and Installing Isolator Pads
The isolator pad mounts are to be located as shown in
Figure 4.1
After the isolator pads have been placed into position on
the floor, lower the chiller onto the pads. When the unit is
in place, remove the rigging equipment and check that
the unit is level both longitudinally and transversely. The
unit should be level within 6 mm from one end to the
other end and from front to the rear. If the chiller is not
level within the amount specified, lift it and place shims
between the isolation pad and the chiller tube sheets.
(Shims furnished by the installer.) Lower unit again and
recheck to see that it is level.
