JOHNSON CONTROLS
FORM 102.20-N1 (1109)
GENERAL
This manual has been prepared as a guide for
installing, operating and maintaining YORK Solution
Air Handling Units. Johnson Controls has produced a
quality product that is adaptable to almost any comfort
or industrial application. However, proper installation,
operation and maintenance must be followed to realize
the full capacity and life of the units.
This instruction contains general recommendations,
but specic requirements may apply to the individual
installation. Such requirements are outlined in federal,
state and local safety codes. Strict compliance with these
codes and strict adherence to these instructions are the
responsibility of the user. Particular attention should
be given to electrical wiring and other safety elements
such as design working pressures and requirements
of the Government Clean Air Act Amendments as it
applies to refrigerant types and charges. General safety
practices are covered in AMCA Publication 410-90.
Read the entire instruction before installing or operating
the air handler. Specic details and requirements apply
that require careful consideration to avoid damage to
the equipment and injury to the installer or operator.
The YORK Solution features segmented construction
and is factory assembled. Segment arrangements will
vary to suit job application (see Fig. 1). Heavy gauge
galvanized steel is used on the exterior and interior of
the unit. Access doors are provided for accessibility
to the various sections. Removable access panels are
standard in lieu of doors on Commercial Performance
units. Panels and doors are double wall construction.
Panels, doors and structural frame are insulated with
spray-injected foam.
TYPICAL YORK SOLUTION OPERATION IN
“HVAC” SYSTEM
The operation of these units can be divided into sys-
tems:
1. Ventilation system.
2. Economizer system (return air/mixing box sec-
tion).
3. Heating system.
4. Cooling system.
Ventilation System
A ventilation system simply replaces the air in a given
space. Usually the purpose is to remove air that is
substandard to creature comfort or a process and replace
it with suitable air. Depending on the application the
system will operate at various specied rates, volumes
and conditions. A ventilation system may employ an air
handler with a supply fan working in conjunction with
other remote exhaust fan(s). A more effective method
would employ both a supply fan and an exhaust fan in
the air handler.
