SWITCHING RELAYS
INSTALLATION INSTRUCTIONS
APPLICATION
The R4222 and R8222 are general purpose relays for use
in refrigeration and air conditioning equipment, vending
machines, and other applications requiring general
purpose switching. R4228 and R8228 are heavy-duty
relays with the same application.
A variety of switching configurations are available. Refer
to Tables 1 and 2. Contacts are available for Powerpile
(millivoltage), pilot duty, and power pole applications.
R4222 and R4228 models have line voltage; R8222 and
R8228 models have low voltage coils.
INSTALLATION
1 Installer must be a trained, experienced
service technician.
2 Disconnect power supply before beginning
installation.
3 Always conduct a thorough checkout when
installation is complete.
LOCATION
Mount the relay on a flat, solid surface as close as
possible to the equipment being controlled. The relay
may be mounted in any position except with the
terminals pointed down. Secure in place with two
screws through holes or slots in the mounting base. See
Fig. 1 for mounting dimensions.

WIRING
Disconnect power supply before making wiring
connections to prevent possible electric shock and
equipment damage.
All wiring must comply with local codes and ordinances.
Crimp female quick connects to the system wires and
attach to the male quick connect terminals of the relay.
The relay has molded terminal numbers and a circuit
diagram for easy identification when wiring. Fig. 2 shows
the terminal location and circuits of all models.
Do not exceed contact and coil ratings when wiring into
the system.
Contact ratings
R4222 and R8222 contacts are available for pilot duty,
power pole, or millivoltage applications. R4228 and
R8228 contacts have power pole ratings only. See
Tables 3 and 4.
