I ordered the penguin from Camping world, 1-877-872-6068,
I got the # 300 DOME413 auxillary drain kit, it had be shipped direct from
Dometic.
I got the #10906 ceiling assembly, this is the inside unit with the overhead
control, i did away witht he four wire wall thermostat. This is your option,
if you still want the wall thermostat, know how many wires / conductors are
inside the jacket when you order it.
I got the #10903 penguin 13500 AC, this is the outside unit. (compressor and
coils).
And i also got the #7971 optional heat strip.
It all together ran aroun $917.
The Dometic is not availble at Inland RV. They sale Carrier units only. They
told me they did have an auxillary drain kit available also, but it was one
they had made to fit. (?) I wasn't to sure about it. And I had already ordered
the Dometic by the time they had returned my call.
You will need to remove the old unit. I used the "saws-all" and quickly got
it out of the way.
My old inside unit had a large yellow frame with a fan. When this was
removed, it left a large gap in the ceiling inside lining. This gap is larger than
the penguin inside ceiling assembly. My ceiling lining is not oval, it has two
channels that run down each side of the previouse a/c, and the vents. There are
wires running inside these channels. I covered my gaps using two old strips
of aluminum from my local "airstream dumpster"
You will then need to cut out a 14 1/4" x 14 1/4" hole. I used a
"saws-all"with the fine metal blade. Be sure to include the existing openings from the
previous unit inside your hole, or you must patch them. The penguin uses an exact
14 1/4 x 14 1/4 hole. Then I made a wood frame from 1 3/4" birch strips from
Lowes. This fit between the outer shell and the inner lining. I screwed this
between the two linings using small stainless steel screws.
Remeber to drill a hole in the galley side to insert the power (and
thermostat) cables.
I installed my auxlliary drain kit and heat unit before installation.
When installing the outer and inner units, the screw together and clamp
themselves in place. During this clamping the inner unit will bend at the controls
slightly, conforming to the shape of the airstream. This bending, kept the
final inside cover and filter s from fitting exactly. I had to over cut the
control knob holes to get it to go on. I also had to use the optional screw stands
(already inside the cover) to secure it in place.
My inside cover hides the channel gaps at the front, but the channel gaps in
the rear still remain exposed. It is about an inch by two inch gap. I plan to
fill it with painted wood.
In hindsite, I may have been better off to build an additional inside,
dropped down frame, to allow the unit to seat squarely. But this may have cut into
my head room....?
I hope this helps!!
