Hayward Goldline AQ-TROL-RJ AquaTrol installation question

[snoopytjp]

I just helped my Uncle buy this SWG:

http://www.amazon.com/gp/product/B002EL40NG/ref=oh_details_o01_s02_i00?ie=UTF8&psc=1

He has to mount it horizontal and when we ordered it I did not know there were two versions. Can we use this one horizontally or should we return it and get the -HP version? Should be ok returning it since we bought it from Amazon.

Thanks!

You can either exchange it, or add the parts that the other version includes, which are available separately. The HP version includes a flow sensor, which is required for horizontal installs, and a second hose adapter, which you may or may not need depending on how things are plumbed.
