OK, this is becoming a problem quickly, so I need some advice.......
We just built a new building last winter and moved in about June. Our
computer/telecom room was spec'd out with its own AC unit as I
Our plans originally called fro a sanyo split ductless unit. Kit #
24KHS32, consisting of units KHS2432 & CH2432. Apparently before the
building was finished, that unit was no longer available and the
"factory replacement" was kit # 24KHS72 which is comprised of units
KHS2472 & CH2472.
I knew something was wrong from the day it showed up (the indoor unit
was about half the size of what I was expecting). I brought it up to
everyone, and was continually told. "Thats the right unit"! I pulled
out the plans and said.... "no, it's not". I only later really found
out why the units were changed. The unit was installed and after a
few problems were fixed (broken fan cage inside) the unit ran great.
Here's the problem: we later found out, the "new" kit doesn't have a
low ambient kit. It only works down to 41 degrees. This is a problem
in Colorado. As it turns out the old kit did have low-ambient
control, but only down to 23 degrees. So really, had we even gotten
the original unit, we likely still would have had problems in the
My server room was 90 degrees when I came in this morning. I've been
trying to get these guys to get me a solution for months now, and
everyone is dragging their feet. I need resolution ASAP!
The engineer has now spec'd out a new unit. It is 26KHH72R (KHH2672R
& CH2672R). This unit has a low ambient control down to 0. Sounds
My question is, can anyone else come up with a cheaper/easier
solution? I guess basically I was wondering if the current outdoor
unit can simply be replaced with a low ambient unit while leaving the
indoor unit alone? I hate to tear out the whole thing, but will if
