I am going to install my new raypak 8350TIE and have a couple questions. first the way they plumbed my filter I need to have the heat pump about 8 ft away from the filter. It looks to me that I will need to put the 2 in underground for the inlet and outlet because it would be a tripping hazard to get to the Pentair panel that is mounted on the garage wall for the pool. do you see any problem with this thought on the install? second in the instruction manuel it says that over 2 hp there should be a bypass valve installed, should there also be a valve on the inlet and outlet pipe also?
