Hi, was hoping someone could give me a few pointers. Im having a Hayward h250fdn heater put in. I have the gas guy doing the hook up and an electrician do the electrical (obviously!). so that leaves the plumbing, and i wonder about the hookup to the control panel. As you can see its a pretty simple setup, but i have a few questions about doing the plumbing was hoping someone could help me out with. Of course if anyone has any other tips for me id love to hear it.
1. The Hayward heater can be switched to have the water intake / output on the left side as opposed to the right side (comes on right side out of the box), that means if i leave the intake and output on the right side ill have to run the plumbing around the front of the heater i guess? Is it hard to switch the intake sides on this heater?
2. Does the electrician normally hook up the heater to the control panel or is that something i would do?
3. Should i put in some shut off valves in the plumbing, and add one before the skimmer as well?
4. Should i put in a check valve between the SWG and the heater? Is it ok if the SWG stays oriented horizontally or does it need to go vertically as i've seen in some photos?
