When using an external drain system, the
condensate is removed through either of two
drain holes on the back of the wall sleeve. Select
the drain hole which best meets your drainage
situation and install the drain kit. Seal off the
other with a cover plate.
Place the drain tube through the gasket and the
mounting plate with the flange toward the wall
sleeve.
Attach the drain tube assembly to one of the
two drain holes at the rear of the wall sleeve.
The large flange on the mounting plate is
positioned at the bottom of the sleeve facing

Architectural Louver Installation (PXAA)
CAUTION:
Bodily injury can be caused by louvers falling from a
building during installation. It is recommended that a
safety line be attached to the louver and an anchor
point inside the building during installation.

Installation
1. Screw a threaded metal stud into each of
the holes at the four corners of the louver.
2. From inside the building, grasp the louver at
the vertical supports and maneuver the
louver through the wall sleeve. Pull towards
you until the threaded studs are inserted into
the four holes of the wall sleeve.
3. While holding the louver with one hand, start
washers and nuts on each of the four studs.
Tighten the nuts securely.

WallMaster® PTAC/PTHP Engineering Specifications
All units shall be factory assembled, piped, wired and fully charged with R-22. All units shall be certified in accordance with
ARI Standard 310 for air conditioners and ARI Standard 380 for heat pumps. Units shall be UL listed and carry a UL label.
All units shall be factory run-tested to check operation and be Friedrich WallMaster® or equivalent.
The basic unit shall not exceed 16" high x 42" wide. Overall depth of the unit from the rear of the Friedrich wall sleeve to the
front of the decorative front cover shall not exceed 21¼". The unit shall be designed so that room intrusion may be as little
as 7¼". Installations in walls deeper than 13 ¼" may be accomplished with the use of a wall sleeve extension (PXWE). Unit
shall draw in ambient air through both sides of an outdoor architectural louver or grille measuring 42" wide x 16" high and
shall exhaust heated air out the middle portion of the louver. The architectural louver and wall sleeve shall be designed so
that the louver may be installed from the inside of the building.
REFRIGERATION SYSTEM - The refrigeration system shall consist of a hermetically sealed rotary compressor that is
externally mounted on vibration isolators no smaller than 1 ¾" dia. X 1 ½" high; condenser and evaporator coils constructed
of copper tubes and aluminum plate fins; and capillaries as expansion devices. Unit shall have a fan slinger ring to increase
efficiency and condensate disposal and have a drain pan capable of retaining 1½ gallons of condensate. A tertiary condensate
removal system shall also be incorporated for back up and shall overflow through the wall sleeve and to the outside of the
building as a safeguard against damage to the interior room.
AIR HANDLING SECTION - The evaporator and condenser fans shall be driven by a single, totally enclosed, ball bearing,
permanently lubricated split capacitor, "clam-shell" style fan motor. Airflow shall be directed into the room by a single,
injection molded, high-impact polystyrene discharge grille. The grill shall have openings no larger than 3/8" high x 3" wide
to prevent personal injury or damage to the PTAC unit, and will be reversible to allow air to be directed upward or outward as
determined by the installer.
The chassis shall have a built-in damper capable of providing at least 60 CFM of fresh air into the conditioned area. A fine
mesh screen shall filter the incoming fresh air. There must be a provision for locking the damper closed to ensure a proper
seal.
CONTROLS - Covered controls shall be accessible in a compartment at least 9" wide with the controls no deeper than 1¼" in
the opening to facilitate easy operation of the unit. Controls shall include dual rotary knobs for setting of the thermostat and
for mode control. The knobs will be tamper proof to prohibit the removal of knobs by the user and shall feature a temperaturelimiting device adjustable by the owner. The control panel shall be clearly marked and easy to read. Universal symbols shall
be used with markings no smaller than 12-point type. The chassis may be ordered with the option of remote thermostat
control.
Other controls accessible without removal of the chassis shall include fan cycle switch, fresh air vent control and emergency
heat override switch (heat pump only).
GENERAL CONSTRUCTION - The wall sleeve shall be constructed of 18 gauge G90 zinc-coated steel. It shall be prepared
by a process where it is zinc phosphate pretreated and sealed with a chromate rinse, then powder coated for maximum
coverage and protection. The sleeve shall be shipped with a protective weatherboard and a structural center support, and be
insulated for thermal efficiency. The grille or louver shall be shipped separately and made from stamped or extruded
anodized aluminum. All louvers shall be in the horizontal plane.
The front panel shall lock to the chassis by means of two factory-supplied thumbscrews to prevent tampering. The front
panel will feature a contoured discharge with no sharp corners. The air filters shall be reusable and be accessible without
removal of the front cover.
All 265V units shall possess an integral, over-current time-delay protective device.
The unit shall have a plastic fan, fan shroud and drain pan for corrosion protection and to help prevent rust on the side of the
building below the outdoor louver.
A complete line of accessories shall be available from Friedrich to equip the PTAC for a multitude of applications.
Friedrich Installation/Start-Up Specialists shall be available to answer questions regarding proper installation practices and
in some cases for on-site start-up inspections.
