Frequently asked questions
Can I use it outdoors without an enclosure?
Yes. The PF03B has an IP44-rated housing that resists splashing water and humidity, so it's suited to covered patios, pump pits and garages without a separate enclosure.
What's the difference between PF03 and PF03B?
Same monitoring features — the PF03B adds a weather-resistant outdoor housing. The PF03 is the indoor model.
Do I need water level sensors?
No. It monitors the pump's power draw, so there are no float switches or in-pit sensors to install.
