If the VAV boxes in the conditioned space
have hydronic heating coils installed, it is
the responsibility of the installing contrac-
tor to take appropriate measures to protect
the hydronic coils against low unit supply
air temperatures that could result in the
freeze up and rupture of the coils.
UNIT INSPECTION

ment must be commissioned and serviced
by an authorized Johnson Controls service
mechanic or a qualified service person
experienced in packaged rooftop instal-
lation. 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
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.
LOCATIONS AND CLEARANCES
General
The YORK YPAL air conditioning units are designed
for outdoor installation. When selecting a site for in-
stallation, be guided by the following conditions:

2. For the outdoor location of the unit, select a place
having a minimum sun exposure and an adequate
supply of fresh air for the condenser.
3. Also avoid locations beneath windows or between
structures.
4. Optional condenser coil protection should be used
for seashore locations or other harsh environments.
