electrical or communication cabling for
wall-mounted mini-split and VRF evaporator
installation. If you want to do Marketair

PartsXP RoughinBox which is introduced by
MarketAir is an innovative, less installation
cost method for roughing in VRF evaporator coil
units and wall-mounted mini-split. All these
models including Lineset rough in box RBX2-SD-NC
and RBX3-MD-NC will reduce rough-in time by
creating a central point with dedicated ports at
which condensate hoses, line sets, and electrical
cabling can terminate safely. Once the Marketair
Roughinbox installation, piping, and wiring are
done, the surrounding area is ready for further
sheetrock installation, painting as well as
mini-split evaporator connection.

Marketair RoughinBox Installation Preparing the
RoughinBox Select 1/2 inch or 1/4 inch port as
needed when you are using a cable port. Now, you
have to cut as X marked on the top of the port
with a utility knife and push the cable through
the opening. This will create an integral strain
relief bushing for preventing cable from pulling
out by itself. If your box includes five lineset
ports one on each end, one on the bottom, and two
on top. For the bottom or top line ports, line
sets from the evaporator should run from right to
left so facing front of RoughinBox. You have to
try always to bring linesets into the box from
left to avoid difficult connection to the
evaporator. Make sure that you keep lineset entry
orifice as small as possible by using the cut
lines available on top of the line port cap. Do
not cut below the marked line as it damages the
slot which retains the mounting adaptor. Do not
remove the closure cap at end of the drain outlet
when you are using a condensate pump. For gravity
drain, the box has a bi-directional drain outlet
with 1/6" MIPT threads which offers two choices,
i.e., for side discharge and bottom discharge.
You can check the owner's manual to get complete
details on this. Remove all four mounting
adaptors from slots at both ends of the box and
invert them. So, you have to fix holes on the top
face up and fixing holes on the bottom face down
and replace them into the same slot. Check
brands installation instructions to find the
minimum distance between evaporator and ceiling
and you can note these dimensions on studs.
Generally, the recommended minimum dimension
between baseline and ceiling is 20 inches. Later,
position the mini split rough in new construction
box correctly with evaporator and mark studs
accordingly.

If studs are metal, you need to determine which
end of the box will face the open side of the
stud. Also, extend mounting adaptors on that end
to their full length of 1 1/8 inches so that they
reach the stud to touch flat surface and lock
them into the position. If studs are wood, you no
need to extend the mounting adaptors and can use
them for fixing.
Install Lineset and Cable First, line up the
RoughinBox base with the mark on the studs.
Insert the box in between the studs and attach it
in place by using the four integral mounting
brackets. Moreover, rear face of the mini split
rough in a box should be flush with the rear stud
surface to ensure that the front face of the box
protrudes 1/2 inch from front stud surface. Make
sure to check that the box baseline never be the
bottom of the evaporator.

low Price Cut around faceplate only along top
and bottom side edges. You have to cut the bottom
edge partially so it will form a hinge for the
faceplate to fold down and access to the
interior. Cut inwards from corners only. Insert
minimum 12" of lineset through a selected port.
Insert cable also but leave 48" slack to reach
the terminal block in the evaporator.

Install Evaporator Now, you can know how to
install an evaporator. By using two plastic
clips provided in the kit, you have to close off
the aperture by refitting the faceplate which
remains in place until the sheetrock and painting
are completed. You can attach 4 optional making
pins onto each corner of the front surface of the
box to facilitate marking the position of the
RoughinBox before the installation of
sheetrock. Next, attach vertical or horizontal
drain line as required to drain outlet and
connect the balance of drainage system to ensure
the drain is completely clear, all joints are
watertight, and drain slope is sufficient. Now,
cut along the bottom hinge and remove the
faceplate completely to expose the cable and
lineset. You need to discard the faceplate when
using gravity drain. Find the correct position
of the evaporator and install it. If the
evaporator bracket requires further fixing to
wall, you can insert plastic bracket support into
the interior slot at bottom and top of the
box. We recommend you that prefer the direct
connection between the evaporator drain hose and
drain outlet in box. Otherwise, remove plastic
drain hose nipple and cut evaporator drain hose
down to the required length. Next, insert it
loosely into a sloped drainage pump.

If you used a pump for the faceplate, condensate
removal, and detachment, you have to provide a
mounting bracket for the pump. Now, you need to
mount the pump onto faceplate with screws and
slide it into the internal slots provided along
the bottom of the box back and front faces to
lock into place. Next, connect and wire pump as
per the manufacturer instructions. PartsXP is
