l'unite hermetique
Hello guys, need help, brain frozen!
Installing a replacement l'unite FH4518 HR condensing unit to an old Hubbard condensing unit for a cellar cooler. Unfortunately the modern day version of the FH4518 is not the same as the one I have removed from the Hubbard housing. The new condensing unit has come with a lp/hp combo fitted with 3 wires, the old one had separate controls. The problem is although the unit has pre-fitted controls, it is not pre-wired, the only thing that is wired is the compressor. All the other wiring - fan,lp/hp,crankcase heater is just randomly attached to the terminal block,needing additional wiring, is this normal for these? The wiring diagram that came with it only covers the compressor.
It got to about half past seven this evening and my brain just gave up, had to walk away. Could any of you guys help me out with how to wire it?
The hubbard unit is a hcu 160, the l'unite is a FH4518 HR. I'll look at it tomorrow and probably suss it straight away, but there's too much going on in me head at the mo.
Any help greatly appreciated
Andy
