FibroPool Heat Pump Installation Guide (Covers ALL Models)

In this video, we'll walk you through the entire installation of one of our heat pumps (in this case the FH055/255). If you purchased a different model, don't worry-all models have a very similar process. The 3 way bypass valve is required only:
1. If pool pump is 1.5 hp or more
2. If plumbing is 2"
3. If you have multiple return jets on your pool (at least 3 returns).

What if my pressure gauge is at 3.7 mpa, is that a problem?

[@Fibropool]

Yes that's a problem. My first guess is that your heater isn't getting enough water flow to collect heat from your unit, so it's building pressure inside. Could be either an underpowered pump or a bypass that's not open enough (if you have one). You may be sending just enough water to not trip the flow switch.

This is soo wrong. Where is the one way value for the heater return. In this config you are still going to feed the heater when you bypass the heater only in reverse way. Come on guys. People are going to follow your video and should not be this bad. Also, there should be a one way valve just before the salt generator.

When you have a situation like this with gravity drawing water away from the heat pump and salt generator, those are good points but not strictly required. Still, there is nothing wrong with adding those valves in this situation, and we do generally recommend including them, if possible. Thanks for the comment!

Thanks for this comment! Unfortunately, I didn't read it before I set everything up. So now I'm going to have to adjust and add a one-way valve to the heater line that feeds to the Tee. Would a one-way check valve for sump pump work? Or is there something else I need to get?
