Product Usage Instructions
Electrical Connections for Permanently Connected Electric Compressors
WARNING: Electrical installation and service must be performed by a
qualified electrician who is familiar with all applicable electrical codes.
The motor rating, as shown on the motor nameplate, and power supply must have
compatible voltage, phase, and hertz characteristics. Ensure that the motor is
rated for the correct voltage (230VAC) and phase (single phase).
Minimum Wire Size
NOTE: Use 75-degree C copper wire for the following instructions.Make
sure the voltage is correct with the motor wiring. Refer to the motor label
for the running HP rating. This will determine the size of wire needed. See
the example below:

PRESSURE SWITCHIf using a 208-volt single phase, ensure that the motor nameplate states it is rated for a 208-volt single phase. 230-volt single-phase motors do not work on 208 volts unless they have the 208-volt rating.
Wire Size Chart
| Model | Single Phase HP | AMPS | 230V Wire Size |
|---|---|---|---|
| C602H | 3.7HP | 17.2 | 10-Gauge |
| C801H/C803H | 5HP | 22 | 8-Gauge |
Recommended wire sizes may be larger than the minimum set up by local ordinances. If so, the larger wire size should be used to prevent excessive line voltage drop. The additional wire cost is very small compared to the cost of repairing or replacing a motor electrically starved by the use of supply wires that are too small. Also, if a lead wire longer than 6ft. is needed, consult a local electrician for alternative wiring options.
Grounding Instructions
WARNING: Improper grounding can result in electrical shock and can
cause severe injury or death. This product must be connected to a grounded,
metallic, permanent wiring system or an equipment-grounding terminal or lead.
All grounding must be performed by a qualified electrician and comply with
applicable electric codes.
Pressure Switch Wiring Instructions
WARNING: The instructions provided below are intended to aid a
certified electrician who is familiar with all applicable electrical codes. Do
not attempt unless you are a qualified electrician. Before performing the
following steps, make certain electrical power has been shut off. Confirm with
a voltage meter that no power is being supplied from the circuit.
- Turn the switch to the off position.
- Loosen the Phillips head screw from the cover.
- Remove the cover.
- Loosen the cord clamp on the rear of the switch and route the correct gauge wire (refer to the Wire Size Chart above) through the clamp opening. Keep the wire length as short as possible to allow the wires to fit under the switch cover when reassembled.
- Install a ground wire to the pressure switch metal body using the supplied ground screw. Torque the ground screw between 25-30 in/lbs and confirm the connection is tight.
- Loosen both screws noted as “line” on the pressure switch.
- Install/crimp an insulated fork terminal to the black and white wire you have chosen to use for the electrical connection.
ELECTRICAL CONNECTIONS FOR PERMANENTLY CONNECTED ELECTRIC COMPRESSORS
NOTICE
Electrical connections should only be performed by a qualified electrician.
WARNING
Electrical installation and service must be performed by a qualified
electrician who is familiar with all applicable electrical codes.
GENERAL
The motor rating, as shown on the motor nameplate, and power supply must have compatible voltage, phase and hertz characteristics.
WIRE SIZE
The electrical wiring between the power supply and the electric motor varies
according to motor horsepower and other factors. Install adequately sized
power leads to protect against excessive voltage drop during start-up. Refer
to the applicable electric codes in your area for information on selecting the
proper wire size and securing electrical connections. If you connect
additional electrical equipment to the same circuit, consider the total
electrical load when selecting the
proper wire size. DO NOT USE UNDERSIZE WIRE.
MINIMUM WIRE SIZE.
(USE 75 DEGREE C COPPER WIRE) Make sure the voltage is correct with the motor
wiring. Refer to the motor label for the running HP rating. This will
determine the size wire needed. See the example below.
MOTOR LABEL
NOTE
If using 208 volts single phase, make sure the motor nameplate states it is
rated for 208 volts single phase. 230-volt single-phase motors do not work on
208 volts unless they have the 208-volt rating.
Recommended wire sizes may be larger than the minimum set up by the local ordinances. If so, the larger wire size should be used to prevent excessive line voltage drop. The additional wire cost is very small compared with the cost of repairing or replacing a motor electrically “starved” by the use of supply wires which are too small. Also, if a lead wire longer than 6 ft. is needed, consult a local electrician for alternative wiring options.
FUSES. Refer to
applicable local codes to determine the proper fuse or circuit breaker rating
required. When selecting fuses, remember the momentary starting current of an
electric motor is greater than its full load current. Time delay or “slow-
blow” fuses are recommended. GROUNDING. In the event of an electrical short
circuit, grounding reduces the risk of electric shock by providing an escape
wire for the electric current. Ground terminals are identified with a ground
symbol and/or the letters “G”, “GR” or “PE” (Potential Earth).
Compressors equipped with motor starters include a ground terminal inside the starter enclosure. For compressors with single-phase motors having thermal overload protection and no motor starter, the ground terminal is located inside the pressure switch. Ground must be established with a grounding wire size according to the voltage and minimum branch circuit requirements printed on the compressor specifications decal. Ensure good bare metal contact at all grounding connection points, and ensure all connections are clean and tight.
WARNING
Improper grounding can result in electrical shock and can cause severe
injury or death.This product must be connected to a grounded, metallic,
permanent wiring system or an equipment-grounding terminal or lead. All
grounding must be performed by a qualified electrician and comply with
applicable electric codes.
PRESSURE SWITCH WIRING INSTRUCTIONS
WARNING
The instructions provided below are intended to aid a certified electrician
who is familiar with all applicable electrical codes. Do not attempt unless
you are a qualified electrician. Before performing the following steps make
certain electrical power has been shut off. Confirm with a voltage meter that
no power is being supplied from the circuit.
- Turn the switch to the “off” position.
- Loosen the Phillips head screw from the cover.
- Remove cover.
- Loosen the cord clamp on the rear of the switch and route the correct gauge wire (see Wire Size Chart on previous page) through the clamp opening. Keep the wire length as short as possible to allow the wires to fit under the switch cover when re-assembled.
- Install ground wire to the pressure switch metal body using the supplied ground screw. Torque the ground screw between 25-30 in/lbs and confirm the connection is tight.
- Loosen both screws noted as “line” on the pressure switch.
- Install/crimp the insulated fork terminal to the black and white wire you have chosen to use for the electrical connection.
- Use a fork-style insulated terminal rated for the correct gauge wire you are using. (see Wire Size Chart on previous page)
- The wire will need to be stripped to the correct length prior to crimping terminal to the wire. Refer to terminal instructions provided by terminal manufacturer for correct strip length.
- Slide the fork terminal into the proper location in the pressure switch and tighten screws between 22-26 in/lbs.
- Pull on wires and confirm the connection is tight and terminals are crimped properly to the wires.
- Once all connections are confirmed, verify wire lengths in the switch are as short as possible. This will allow the switch cover to be re-installed properly. If the lengths are too long, it will not allow the cover to be installed completely onto the switch.
- Tighten cord clamp screw to 15-25 in/lbs.
- Install pressure switch cover. Tighten the cover screw snug.
- Rotate the switch knob on and off several times to ensure proper rotation before providing electrical power to the compressor.
- If the switch knob does not rotate freely verify the wire lengths again inside the switch. Refer to step 10
- Once all the above steps are complete and performed correctly, power can be provided to the compressor
