Question: on  the ss2 safety switch does it have a normally open contact or is it normally closed?
Document: I bought this product along with AquaGuard AG-1200+ Horizontal Secondary Drain Pan 24v Safety/Float Switch and the rectorseal SS1 horizontal drain (no such thing as too many safeties) all from Amazon. The SS2 was installed on the AC evaporator coil secondary drain pan. Piped it in myself which was very easy along with the other drain pan and float switches. I have a second floor home with furnace in the attic.
this was easy to install and was well described came right on time I would recommend this for anyone looking for a float switch
Had new A/C system installed best of every thing $12,400.00 job , metal duck and a safe-t-switch installed. What could go wrong? The SS1 switch failed and caused over $10,000.00 water in water damage to my new solid wood 5/8&#34; Brazilian Cherry floors ruined.
The ss2 I put in line downstream in my main line going outside. So if any of these were to overflow they will shut my AC/furnace down to prevent property damage. I would highly recommend any of these products to protect your property as they all work very nicely for my application. Worth every penny for that moment you hope never comes.
works great. replaced the old busted one with this one. no problems yet but i tested it by flipping it over seemed to work.
This part is exactly what I was looking for. It fit perfectly and was very easy for the tech to install.
This has turned out great and looked great. This has arrived in time. I'm very proud and very impressed. This product will prevent the central air conditioner from flooding a home if the the drain line is stopped up.
Simple solution for peace of mind that your AC won't overflow.Have tested it after installation, works as described :-)
Our builder didn't add an overflow line and I had a water mess. This is a quick, simple, and inexpensive way to protect against water damage from the AC.
I installed this on my rental unit because the HVAC company that installed the unit actually left the secondary drain unplugged (installed before we purchased the home). I found this out when the tenant notified me of a leak. This unit is easy to install and connect to the system. I tested the unit and it works. I think this should be mandated by law because the unknowing can incur some really big expense for such a low cost item.
Answer: yes
