I've got a 1500 gallon gunnite in-ground spa with a Raypak 406A elec ignition heater.
Professionally winterized in Dec, trying my hand at summerizing before the weekend.
Drained the spa, cleaned all the debris, removed plugs, reinstalled 2 plugs in pump and pump filter, reinstalled big plug in filter, cleaned debris from heater, installed 1 drain plug in heater (on Right hand side near pvc pipes to/from the rest of the works.
Issue #1 - I have an extra drain plug -- cant figure out where it goes- any suggestions? it is gray and looks like the other Raypak plug.
Issue #2 - after opening gas valve, return valve and skimmer valve, what else do I need to do before priming pump, flipping circuit breakers and turning it on?
Issue #3 - do I need to do anything with the filter (bleed air?) before dumping DE into the spa? Anyone know how many pounds of DE I need to use? When do I pump it? Before or after turning on the pump?
Thanks to all
