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
labels or in manuals, be alert to the potential for personal injury.
Understand and pay particular attention the signal words
DANGER, WARNING or CAUTION.
