GENERAL

This manual describes the installation of a YORK YK
Mod "H" Centrifugal Chiller. This unit can be shipped
as a single factory assembled, piped, wired package,
requiring a minimum of field labor to make chilled
water connections, condenser water connections, re-
frigerant atmospheric relief connections, and electri-
cal power connections. Refrigerant and oil charges are
shipped separately unless optional condenser isolation
valves are ordered.
Chillers can also be shipped dismantled when required
by rigging conditions, but generally it is more econom-
ical to enlarge access openings to accommodate the
factory assembled unit. Chillers shipped dismantled
MUST be field assembled under the supervision of a
Johnson Controls representative, but otherwise instal-
lation is as described in this instruction.

FIELD ASSEMBLED UNITS ONLY

Use Unit - Installation Instructions (Form 160.76-N3)
in conjunction with this installation instruction. This in-
struction is furnished with all units that are assembled
in the field.
