My (very old) Pentair UltraFlow pump died a few days ago. My automation system is a Compool 3400. I'm taking the opportunity to upgrade the pump to an Intelliflo VS-3050, and also bought the Compool to Easytouch upgrade system with 1 new hard-wired panel. A have a few assumptions I was hoping you brainiacs could verify, and also a few questions. Thanks in advance for your advice!
1. The VS-3050 manual recommends direct-wire to circuit breaker. The Compool setup has the pump wired to a high-voltage relay (breaker to relay; relay to pump). I'm assuming I can bypass the relay with the EasyTouch and go right to the pump, then connect the pump controller cable to the EasyTouch panel for control of on/off & speeds. Yes?
2. The existing setup has a water-temp sensor, and I now have a new sensor with the new equipment. Can I just use the old/installed one (Compool standard issue), or must I use the new one with the EasyTouch? (I don't want to assume the hole in the return-line is the same size for both, and want to minimize the PVC cutting and replacing.)
3. I have a spa-side wired-remote (4 push-switches) with the Compool, 1 switch each for pump, heat boost, lights & air-blower. It's 6-wire, which is what the EasyTouch calls for as well - anyone know if I can re-use the existing remote, or is it not compatible with ET?
4. Everything with the existing install is glued PVC - no unions at all. I can cut-out and do all new with glue, or take the opportunity to put in a couple of unions - but I also don't want anything to leak. Any opinions on unions in general? Do I need to use a lubricant on the union gaskets (as with the pump-strainer and DE filter O-rings?
5. Seems the old Compool remote (wired) panel and new EasyTouch panel should be plug & play with the existing modular (6-conductor) cable and connector. True?
And finally, any other experience-based advice? You guys always have tons of relevant info, and I'm anxious to learn BEFORE I make a series of mistakes!
