Application
The P266 Series Single-Phase Condenser Fan Speed
Control is a cost-effective, compact, weather-resistant,
and durable speed control for single-phase PSC
motors used in a wide variety of low-ambient
refrigeration and air conditioning condenser
applications.
The P266 Series Fan Speed Controls are designed to
replace the Johnson Controls® P66 Series and P215
Series Fan Speed Controls and provide additional
features and application flexibility.
Mounting
Location Considerations
Observe these guidelines when locating and mounting
a P266 Series Fan Speed Control:
•
Ensure that the mounting surface and mounting
hardware can support the control and wiring.
•
Mount the P266 Series control upright on a vertical
surface with the heat sink fins oriented vertically
and the conduit/electrical holes facing down.
•
Ensure that air can flow through the heat sink fins
and provide 10 cm (4 in.) minimum clearance
around the heat sink.
•
Mount the P266 Series control in a location away
from sources of excessive heat and within the
specified ambient operating conditions. See
conditions.
IMPORTANT:
Use this P266 Series Single-Phase
Condenser Fan Speed Control only as an operating
control. Where failure or malfunction of the P266
Series Fan Speed Control could lead to personal
injury or property damage to the controlled
equipment or other property, additional precautions
must be designed into the control system.
Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit
controls, intended to warn of or protect against
failure or malfunction of the P266 Series Fan Speed
Control.
!
CAUTION: Risk of Property Damage
Use only single-phase Permanent Split
Capacitor (PSC) motors approved by the
manufacturer for speed control
application with the P266 Series control.
Failure to use a single-phase PSC motor
may damage the motor and other
property.
