Hypertherm 128882 Flow Switch

Part Description

The Hypertherm 128882 flow switch is a replacement part for the HT4400 Chiller. The flow switch is responsible for monitoring the flow of coolant through the chiller and shutting off the chiller if the flow rate drops below a safe level. This helps to protect the chiller from damage.

Specifications

The Hypertherm 128882 flow switch has the following specifications:

• Maximum Flow Rate: 5 GPM
• Minimum Flow Rate: 0.5 GPM
• Operating Temperature: 32°F to 120°F (0°C to 49°C)
• Storage Temperature: -40°F to 150°F (-40°C to 65°C)
• Electrical Rating: 120 VAC, 1 A

Installation

The Hypertherm 128882 flow switch can be installed in the following steps:

1. Turn off the power to the chiller.
2. Disconnect the water supply and drain lines from the chiller.
3. Remove the old flow switch from the chiller.
4. Install the new flow switch in the reverse order of removal.
5. Reconnect the water supply and drain lines to the chiller.
6. Turn on the power to the chiller.

Troubleshooting

If the Hypertherm 128882 flow switch is not working properly, the following troubleshooting steps can be performed:

1. Check the flow rate of the coolant. The flow rate should be between 0.5 GPM and 5 GPM.
2. Check the temperature of the coolant. The coolant temperature should be between 32°F and 120°F (0°C to 49°C).
3. Check the electrical connections to the flow switch. The connections should be tight and secure.
4. If the flow switch is still not working properly, it may need to be replaced.

Conclusion

The Hypertherm 128882 flow switch is an important part of the HT4400 Chiller. The flow switch helps to protect the chiller from damage by shutting off the chiller if the flow rate of coolant drops below a safe level. If the flow switch is not working properly, it should be repaired or replaced as soon as possible.
