so we had some issues with the previous landlords not taking care of the hot tub we own... i don't know it's brand, i know the Digital Control was Mad by CTI, the Spa Pack is a minmax CTI made pack as well... apparently the previous owners bought and installed the pack themselves... and in my opinion did a bad job, but that's beyond the point...

anyhow... i had to replace the pressure switch on it as something had happened *either they did not add the scale stuff or it got froze to death with the rest of the stuff* so i got the beast apart and replaced the pressue switch with ease... and then i realized i had labeled and drawn where everything went, except the pressure switches two connectors... i know where they connect to, i just don't want to hook it up and short out the new switch, or the board... or break anything else...

the switch is a basic one that looks exactly like this except not broken, and attached...

there are two prongs on the switch, ones labeled C *the top one* and the bottom on is labelled N0... on my board i have two corresponding attachments, one is labeled j18 and the other j19... it does not tell me on the schematics what one is what....


i know i have a airlock in the system as well... it was bound to happen with all the repairs i have done... and i would like some tips on how to beat that as well... but mainly i don't want to blow things up... here's what i've repaired and replaced so far...

3 feet of hose cracked and broken from freezing
Coupling on heater tube broken from frezzing
entire filter system broken from freezing
had to take out half the side covering due to mold
and then the pressure switch

i still havn't gotten to replacing the side wood paneling as that is mostly cosmetic and i need to put some insulation in there or it will freeze again...

here are some pics... thanks for the help...
