Trying to hook up the defrost so it will energize some heat during the
defrost cycle. It says run a lead from D on the heat pump to P on the
air handler. Only problem is, I seen no P terminal on the air handler's
Apparently you can't read a schematic?? or the installation instructions??
This is basic controls, with basic wiring.
You do know that Rheem equipment RVs are energized in heat, I would hope
What model heat pump??
What model of air handler are you using with it??
What control are you using with it??
The only thing the schematic shows is the heat pump end, not the air
handler end. It shows a picture of the terminals, but there is no P
Rheem RPPB-036JAZ heat pump.
Rheem RBHK-24J14SHD air handler.
Why are you putting in an R22 heat pump when in a year, R22 is going to
become *VERY* scarce and *VERY* expensive??
You have already proven that you not a tech, but a home owner trying to DIY.
Take a crowbar to your wallet and call a local tech that knows what he is
doing.... who knows what else you might have screwed up in the process.
BTW... you do realize that the warranty on *ANY* Rheem equipment bought over
the internet is null and void.
1. This is an EXISTING heat pump that was installed in 2005.
2. I already called the tech and he says he doesn't know anything about
that and furthermore, he is too busy to fool with it. He says he has
100 calls to make on units that are out of service and. Says if my
system breaks down, call him.
3. I did not buy this system on the internet, It was installed by
the above mentioned tech.
4. It's just a simple connection. All I want is for the heat strips
to kick in when the thing goes into defrost. I waited till warmer
weather to do it so I wouldn't freeze my butt off trying to hook it
up in the winter. I looked in the unit outside and the D terminal
is already connected to the purple wire. But it ends inside the
air handler without being connected to anything. I don't think it
takes a highly educated tech guy to connect 1 wire.
5. So, if R22 is going to be obsolete, what are we gonna do? Does
this mean we have to buy another new unit or will there be a drop-in
replacement for R22 like there was for R12 a few years ago? I used
to convert R12 cars to R134A but not much need for that any more.
There's several years of R-22 out there, in HVAC shops and
on the trucks. Enough for a while. The new R-410a, which is
marketed as Puron, and some other names. Supposed to do the
job nicely. It won't work in the old systems. As the price
of R-22 goes up, someone is sure to develop a drop in
Ah, well. All the numbers. 12 went to 134a (with oil change,
and new metering device). The newer equipment is designed
22 is going to, something else. Either a drop in blend, or
maybe the equipment will die by the time it's needed.
502, couple replacements. 408a comes to mind, and the new
404a with new oil and new equipment.
It's all big blur of numbers.
Can't you install an R22 metering device on a new coil?
If it won't take an orifice/piston for R22, braze an
expansion valve on it. Have you never converted a system
over to another refrigerant? I've done a number them.
Thats great if you can find a coil that will fit in a Rheem/RUUD air handler
for a heat pump.
I have done several conversions also, but that is a gross injustice to the
customer....unless you one of the local low ballers who doesn't give a crap
about anything but grab the money and run.
I assumed he was talking about a cased coil, not putting a coil
into an existing case. Good grief, I can't count the times we've
had to cut out an old coil, case and all, and install a new one.
The question still remains.... with the HCFC phase-out, does the customer
want to pay the almost $2,000 to replace a leaky coil, or put that money
towards a new system that has a 10 year unit replacement warranty, will cut
their power bills in half, and not have to worry about if the refrigerant
will even be available in the next couple of years.
The whole thing is to present the customer with facts, information, and
hand-outs to back up what you tell them, and let them make the decission of
what they want to do, and if they opt for a new system, let them tell you
what system they want you to install so its win-win. Either way, you want
the customer to be happy to write that big check, and you'll be doing the
happy dance all the way to the bank.
Its all about *service*, not serve-us.
