INDOOR UNIT
Use the specified refrigerant only
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the spec labels provided with our products.
We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.

1. Fresh Air Intake
Air recycled indefinitely can become stale and stagnant with air quality suffering significantly. Fresh air is the
answer and it is for this reason that the PMFY- series takes in air directly from outdoors. This fresh air intake
allows you to enjoy the comfort of crisp, refreshing air in the confines of your living or working space.
2. Light and Compact
The main unit weighs only 31 lb. and the panel merely 7 lb. This makes the PMFY- series one of the lightest in the industry. The unit size is also quite small, having been standardized to a strikingly compact 33-5/8
inch. All of this make the chore of installation and maintenance that much simpler and easier.

Operation in conjunction with duct fan (Booster fan)
Whenever the indoor unit is operating, the duct fan
operates.
(1) Connect the optional multiple remote controller
adaptor (PAC-SA88HA-E) to the connector CN51
on the indoor controller board.
(2) Drive the relay after connecting the 12V DC relay
between the Yellow and Orange connector lines.
(w)Use a relay of 1W or smaller.

1 Operation summary of the linear expansion valve
• Linear expansion valves open/close through the use of a stepping motor after receiving the pulse signal from the indoor
controller board.
• Valve position can be changed in proportion to the number of pulse signals.

Closing a valve : 1 → 2 → 3 → 4 → 1

The output pulse shifts in above order.
• When linear expansion valve operation stops, all output phase
become OFF.
• At phase interruption or when phase does not shift in order, motor
does not rotate smoothly and motor will lock and vibrate.
• When the switch is turned on, 2200 pulse closing valve signal will be
sent till it goes to point A in order to define the valve position.
Valve position (capacity)
• When the valve moves smoothly, there is no sound or vibration
occurring from the linear expansion valves : however, when the
pulse number moves from E to A or when the valve is locked, more
sound can be heard than in a normal situation.

Removing the air intake grille
(1) Press the PUSH of the air intake grille, and pull down the
both ends of nut with your fingers after the grille clicked.
(See Figure 1)
(2) Pull out the handle of air intake grille strongly toward you.
(See Figure 2)

Checks before setting the grille in place
(1) Before installing the grille, make sure the indoor unit is
square with the ceiling opening (or parallel to the angle
between the wall and the ceiling).
(2) Check that the 4 points where the grille will be secured are
in contact with the ceiling surface.
(3) Check that the insulation for the refrigerant pipes, drainage pipes, etc. is in place and that wiring connections and
arrangements are complete.

(1) Open the intake grille by pressing PUSH of the air intake
grille and remove the air filter (× 2). (See Figure 1)
(2) Remove the screw cover in the middle of the air outlet. (See
Figure 7)
(3) Open the upper and lower flaps on the indoor unit completely. (See Figure 7)
(4) Remove the securing screws (× 7).

Attaching the grille
(1) Open the upper and lower flaps on the indoor unit completely.
(2) Hook the temporary holding tabs on the front panel to the
hooks on the indoor unit.
(3) Adjust the grille so that it fits properly in the angle between
the ceiling and the wall, and install the securing screws A
(supplied with this grille) in their 4 places at left and right,
leaving them slightly loose.
(4) Tighten the securing bolts A and securing screws B in the
centre 3 places. (See Figure 6)
(5) Tighten the securing bolts A in the 4 places at left and right.
* Make sure there are no gaps between the indoor unit and
the grille, and between the grille and the ceiling surface.
If there are gaps, the wind may come in and it may cause
water to drip. (See Figure 8)
* Tighten the securing bolts A and securing screws B completely.
(6) Replace the air filter and screw cover, and press PUSH of
the intake grille until you hear it snap into place.
