Thanks for everybody's help.
I think I've got it now.
Below are my step-by-step instructions on moving a rig that has to lay down
during the move.
Please let me know if I have something wrong.
TERMS (I hope I have defined them correctly):
Suction line = typically a fatter line, exits from the compressor and is on
the side of the compressor commonly referred to as the "low side." A tube is
attached to it which then runs up the backside of the frig, up to the freezer.
The side of the frig where the suction tube runs up is TYPICALLY the side
upon which you will want to attach your dolly (and the side you want to lay the
frig on... if you must lay it down).
Output line = (also called the compression line?) typically a smaller line
than the suction line, usually on the opposite side of the compressor than the
suction line and is referred to as being on the "high side" of the compressor
system. This line goes to the condenser which is the set of metal coils that
are usually visible all over the back of the frig.
Oil cooling loop = not of concern when trying to decide which side to lay a
frig on.
COMPRESSOR OPERATION:
When the frig is in normal operating mode, air and moisture (or whatever) is
being sucked into the compressor via the suction line and forced out of it via
the output/compression line. Thus, if oil gets into the larger suction line
during transport, it has an easier time returning to the compressor during its
24-hours sitting time (after relocation), because it was in that larger line
instead of a smaller one. Also, and maybe more importantly, any minimal
amount of oil that remains in the suction line will be sucked back into the
compressor once it is turned on. If there was oil remaining in the
output/compressor
line, when the compressor was turned back on it would push that oil away from
the compressor and into the condenser coils.
STEP-BY-STEP INSTRUCTIONS (for moving a frig which has to lay on its side
during transport):
- Borrow or rent a refrigerator dolly.
- If ice has condensed in the freezer, defrost it before you start the
moving process.
- At some point turn the setting on your frig down (i.e., from 3 to 4...
like you want it colder) until you hear the compressor come on (if you have to
defrost the freezer, the compressor will automatically come on when you finish
defrosting and you turn the frig back on). Listen to and remember how the
compressor sounds. You will be comparing that sound to the sound it makes once
it
is at its new location and has been turned back on.
- Turn off the frig, empty it out (including the shelves and drawers) and
unplug it. If you have to move it in order to unplug it, read the next step
before moving it.
- If you have a lower front panel, take if off of the frig (usually pulls
off but may have to be unscrewed). See if you have a drip pan at the base of
the frig and, if so, remove it slowly and dump the water out.
- Consider the pros and cons of removing the doors to the frig (remember
that, with the doors removed, it will be easier to get out and in (both lighter
and thinner) AND the frig's door hinges will not be stressed during the move).
- Move the frig away from the wall (if you haven't already) and see on which
side a large line (the suction line) runs up the back of the frig. Now look
through the back of the bottom of the frig at the compressor (that big thing,
usually black and spherical in shape) and see where the largest tube from the
compressor is located (i.e., the tube that the suction tube is attached to...
which then runs up the back of the frig). If they (the large tube out of the
compressor and the side of the frig that the attached suction tube runs up)
are both on the same side, strap the dolly to that side of the frig. If the
largest tube out of the compressor (the one the suction line is attached to) is
actually located on the other side of the compressor (i.e., the opposite side
from the side which the suction tube runs up the back of the frig... unusual to
find this configuration), attach the dolly to the side of the frig where the
large tube comes out of the compressor (i.e., disregard the side of the frig
the suction tube runs up). If you cannot see the compressor, get someone to
tilt the frig so you can look under it and determine these things. BE CAREFUL.
- Strap the dolly to the side of the frig as indicated above. Put a large
plywood board between the dolly and the frig and a blanket (SMOOTHED OUT)
between the board and the frig before strapping the dolly (with the board and
the
blanket) to the frig. The frig is going to rest on the dolly during transport
and the board and blanket, will be needed if you do not want the frig to end
up with two groves in it from where it was strapped to the dolly. The board
should be as similar in size to the frig as you can find but not larger than the
frig or it will catch onto things during the move. Also the board and
blanket cannot be too thick because the lip on the bottom of the dolly does not
extend out very far. So if you use a thick board and several folded blankets,
the
frig could stick out so far from the dolly that it slips off the bottom of
the dolly. DANGER! If you have taken the doors off, do not strap the dolly too
tightly otherwise you might bow in the sides (at the front) and crack the
interior walls.
- Move the frig to the transport vehicle. ALWAYS move (and transport) a
frig carefully. The compressor has springs in it which become brittle with age
and can be broken if the frig/compressor is jogged to violently.
- Once in the transport vehicle, keep the frig attached to the dolly and lay
it down on the dolly. Keep the top of the frig as high as possible by
placing something between the dolly and the floor. Any height increase in the
top
of the frig over its bottom helps in restricting the migration of the oil
during transport. Secure the rig so that it will not move or likely be damaged
during transport. Keep in mind that, if you have the rig in a diagonal position
(i.e., top higher that bottom) there will be an added amount of stress at the
bottom corner which comes in contact with the dolly (and, consecutively, with
the floor). If there is a way you can cushion that contact (without staining
backs) then do it. You might be able to roll the dolly up onto several folded
blankets (might need a piece of plywood over the blankets). Take the least
bumpy route to your destination. Once at your destination, get the rig upright
as
soon as you can. Once you have it in its new location, let it sit for at
least one day before plugging it in.
- Once your rig has been turned on, listen for any new noises from the
compressor. Clanking noises may be an indication that a compressor spring
(inside
the compressor) broke in transport. Also, if the rig does not get as cold as
it used to, you may have damaged the compressor in transport. If either has
happen, you may need to replace the compressor or buy a new rig. But first,
turn it off, let it sit for a week and then try again. This might not help any
but you never know.
