Intermatic Compressor Defender CD1-024R Instructions D'installation

Model CD1-024R Surge/Brownout/Short Cycle Protective Device
IMPORTANT SAFETY INSTRUCTIONS • SAVE THESE INSTRUCTIONS
WARNING
• Thoroughly read instructions before installing unit.
• Installation and Service to be performed by a qualified licensed HVAC technician or licensed electrician.
• Disconnect power at circuit breaker(s) before beginning installation or servicing.
• More than one circuit breaker or disconnect switch may be required to de-energize equipment before ser-
vicing.
• All wiring must comply with all state and local electrical codes including the National Electrical Code and/
or Canadian Electrical Code.
• This unit contains no serviceable parts.
• This device features an internal protection that will disconnect the surge protective component but will
maintain power to the load--now unprotected. If this is undesirable for the application, follow the manufac-
turer's instructions for replacing the device.
• Do not mount device nipple side up.
• This product is not designed for Rigid Conduit mounting.
The Compressor Defender™ protects HVAC Compressors (Scroll & Reciprocating), and the electron-
ics inside central air conditioners, heat pumps, light commercial packaged rooftop units, and mini-splits
from under/overvoltage conditions, surge events, and system short cycling caused from AC power
interruptions.
Specs
• Input voltage: 120 VAC to 240 VAC 60Hz
• MCOV (Max Continuous Overvoltage):
L-N/G: 150V L-L: 300V
• Type 3 Outdoor Enclosure
• In (Nominal Discharge Rating) : 10kA
• SCCR (Short Circuit Current Rating): 20kA
Installing the Compressor Defender™
A typical installation of the Compressor Defender™ connects to the load side of the electrical service
panel and is intended to be installed with over current protection up to 60 amps to the device. The wire
gauge size should be 10AWG with a minimum wire length of 6 inches to a maximum of 20 inches from
the nipple out.
NOTE: The Compressor Defender™ does not have to be reset after a surge or brownout event.
1. Disconnect condensing unit power at circuit breaker(s), the AC disconnect, and at the 24 VAC
thermostat circuit.
2. Mount the Compressor Defender™ making sure the 24 VAC wire is mounted below the nipple.
See Figure 1.
NOTE: Ensure conductor lengths are as short and straight as possible for best performance. Do
not coil excess wire. The SPD functions best if all bends in wires are rounded, ideally to
a 4 inch radius. Hard 90º bend will reduce efficiency. Cut all leads to the correct length.
NOTE: If you want to install the Compressor Defender™ inside a condensing unit, drill two holes
in the sheet metal and then insert the L clip on the Compressor Defender™ over the holes
and secure the connection with two customer supplied sheet metal screws. See Figure 2.
