The Pocket Wall Unit (PWU) has been designed for a recessed wall application. The unit should be installed
directly to the studwork by the chassis edge and /or adjustable side mounting brackets set to suit the associated
sheetrock thickness and distance between the studs or the unit can be mounted centrally between the studs or
directly to one stud and side mounted bracket used to fix to the opposite stud. The area in front of this unit must
not be obscured or restricted. Vertical surfaces in front of this unit will impede the air flow and reduce it’s capacity.
INSTALLATION PROCEEDURES
Preparation.
Carefully unpack the unit and the top adjustable mounting brackets (x2) from the carton. The front cover grille has
been packed separately and should be stored safely until required.
Fitting centrally between studwork
Mark a distance up from the floor to the desired mounting height. Select the desired thickness of sheet rock to be
used and loosen the screws of the lower adustable mounting bracket and loosely fit the top adjustable mounting
brackets. Measure between the studwork and adjust the brackets to this dimension (D), set the distance between
the top of the studwork and the outer flange of the chassis to that of the sheetrock (E), Place the unit chassis with
the top facing up, level with the mark centrally between the studs when in the correct postion screw the adjustable
brackets to the studwork with suitable wood screws (field supplied) through the six screw holes in the mounting
brackets (two in each flange).
Fitting to left stud.
Mark a distance up from the floor to the desired mounting height. Select the desired thickness of sheet rock to be
used and loosen the screws of the lower adustable mounting bracket and loosely fit a top adjustable mounting
bracket to the top right hand side of the chassis. Measure between the studwork and adjust the brackets to this
dimension (D), set the distance between the top of the studwork and the outer flange of the chassis to that of the
sheetrock (E). Place the unit chassis with the top facing up, level with the mark between the studs when in the
correct postion screw the adjustable brackets to the studwork with suitable wood screws (field supplied) through
the four screw holes in the mounting brackets (two in each flange) and the two screw holes in the chassis
mounting flange.
Fitting to right stud.
Mark a distance up from the floor to the desired mounting height. Select the desired thickness of sheet rock to be
used. Remove the lower adustable mounting bracket and loosely fit a top adjustable mounting bracket to the left
hand side of the chassis. Measure between the studwork and adjust the bracket to this dimension (D), set the
distance between the top of the studwork and the outer flange of the chassis to that of the sheetrock (E). Place
the unit chassis with the top facing up, level with the mark between the studs when in the correct postion screw
the adjustable bracket to the studwork with suitable wood screws (field supplied) through the two holes in the
mounting bracket and the two holes in the chassis mounting flange.
The appropriate size sheet rock can now be fitted around the unit, care must be taken to ensure there is a
½” gap between the top of the unit and the sheetrock. The grille cover will be installed on the chassis
(using the four screws provided) after piping, wiring and air bleeding has been completed.

directly to studwork on one side and adjustable brackets used to fix other side).

Piping Location
Solder the heating system Supply tube to the “back” chassis tube first. Then solder the return line to the “front”
chassis tube. After soldering the Return connection (front tube), check that both connections are leak free.
Note: isolation valves are recommended on both supply and return piping to allow for service and
balancing if necessary.
