There are a number of inspection and maintenance tasks you should complete quarterly on your chamber's electrical system.
Start by inspecting the condition of the chambers and their electrical components:
- Phasing (for bigger equipment with 3-phrase power)
- Check the solenoid covers and coils
- Chamber has at least 3 feet of clearance from the wall
- Check the heater and wiring and ground wiring as well as the wiring harness
- Check the sensor clips and compressor connections
If there is an issue with any of the above, take photos of the affected part(s) and send them to firstname.lastname@example.org.
Quarterly work must also be performed on the electrical system of an environmental test chamber:
- Tighten all connections
- High voltage reading/outside unit
- High voltage reading on the conditioning system
- Control voltage reading
- Compressor amperage reading
- Heat amperage reading
- Control switch test (power, heat, cool, and light)
- Test interior lights
- Control panel cleaning (vacuum or blow out)
- Condenser/Evaporator fan amperage
Preventative maintenance is key to keeping an environmental test chamber operational for a decade or more. A properly maintained test chamber can even last 20-plus years.
We understand this is a long list and isn't always manageable to check quarterly, let alone annually. That's why AES offers chamber check-ups. If you're interested in having a chamber professional take a closer look, contact email@example.com.
