General
YORK
®
Affinity Models DEX and DEY units are factory
assembled cooling units designed for outdoor installation on a
roof top or a slab. Field-installed electric heater accessories are
available to provide supplemental electric heat combined with
electric cooling.
The units are completely assembled on rigid, removable base
rails. All piping, refrigerant charge, and electrical wiring is
factory installed and tested. The units require only electric
power and duct connections at the point of installation.
The electric heaters have nickel-chrome resistance wire
elements and utilize single point power connection.
Safety Considerations
This is a safety alert symbol . When you see this symbol on
labels or in manuals, be alert to the potential for personal injury.
Understand and pay particular attention the signal words
DANGER
,
WARNING
or
CAUTION
.
DANGER
indicates an
imminently
hazardous situation, which,
if not avoided,
will result in death or serious injury.
WARNING
indicates a
potentially
hazardous situation, which,
if not avoided,
could result in death or serious injury.
CAUTION
indicates a potentially hazardous situation, which, if
not avoided
may result in minor or moderate injury.
It is also
used to alert against unsafe practices and hazards involving
only property damage.
Improper installation may create a condition where the
operation of the product could cause personal injury or
property damage. Improper installation, adjustment,
alteration, service or maintenance can cause injury or
property damage. Refer to this manual for assistance or
for additional information, consult a qualified contractor,
installer or service agency.
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
