CEILING CASSETTE PM SERIES
A.6.1 FEATURES
● Indoor (Main) Unit In case of PMH-P2BA
CEILING
CASSETTE PM
1. QUIET AS A MOUSE AND AS INCONSPICUOUS AS ONE TOO, THE PMH-P SERIES IS AN ATTRACTIVE, LIGHT­WEIGHT MODEL THAT MOUNTS DIRECTLY INTO THE CEILING, BLENDING ALMOST SEAMLESSLY WITH NEARLY
FEATURES
ANY INTERIOR.
2. FRESH AIR INTAKE
Auto Air Swing Vane Disperses air flow up and down and adjusts the angle of air flow direction.
Horizontal Air Outlet
Filters Remove dust and pollutants from inhaled air.
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 PMH-P 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.
Air intake Inhales air from room.
Guide vane Air flow can be changed to horizontally by moving the Guide vane to the left or right.
3. LIGHT AND COMPACT
The main unit weighs a measly 14kg and the panel a mere 3kg. This makes the PMH-P series one of the lightest in the industry. The unit size is also quite small, having been standardized to a strikingly compact 854mm. All of this helps make the chore of installation and maintenance that much simpler and easier.
4. AESTHETICALLY PLEASING
Nothing ruins the look of a carefully decorated room more than a poorly designed, bulky air conditioner. With the PMH­P series, there is no need to worry. The unit mounts directly into the ceiling barely protruding into the living space for a pleasant, stylish aesthetic.

A.6.11 TROUBLESHOOTING
Problem
Unit does not cool or heat very well.
The unit stops operating before arriving at the set temperature in the heating mode.
The air flow direction suddenly changes.
A white mist is expelled from the indoor unit.
The indicators of the remote con­troller do not light up when oper­ated.
NOTE: After a power cut, the unit will not restart automatically. You will have to restart it by pressing the POWER - ON/OFF button on the remote
controller.
If none of the above apply, turn the main switch off and contact the dealer from whom you bought the air-conditioner, telling him the model name and the nature of the problem. Do not try to fix the unit yourself.
Wired remote controllers
In any of the following cases, turn off the main power switch and contact your local dealer for service:
• The operation lamp (on the main unit) flashes.
CEILING
CASSETTE PM
TROUBLESHOOTING
• The switches do not work properly.
• The circuit breaker trips frequently (or the fuse blows frequently).
• Water has accidentally been splashed into the unit.
• Water leaks from the unit.
• Something is accidentally dropped into the air-conditioner.
• An unusual noise is heard during operation.
Wireless remote controllers: The Operating LED blinks.
Solution
Clean the filter.
Frost forms when the outdoor tempera­ture is low and humidity is high. Wait for about 10 minutes for the frost to melt.
After one hour of cooling-mode opera­tion with the air flow in a downward di­rection, the unit will automatically change to the “Horizontal air flow” mode.
When the unit is in the heating or de­frosting mode, it will automatically change to the “Horizontal air flow mode”.
This may occur just after the unit is turned on when a high level of humid­ity is present in the room.
Turn on the power switch. “ · ” will be displayed.
Problem
CENTRALLY CONTROLLED is dis­played in the remote controller.
The start and stop functions are not avail­able just after restarting the unit.
“H0” is displayed in the remote control­ler.
An error code is displayed in the remote controller. The operating display of the wireless re­mote controller’s receiver is flashing.
Solution
The start and stop functions of the re­mote controller are not available when the CENTRALLY CONTROLLED mes­sage is lit.
Wait about three minutes (operation has stopped to prevent damage to the air conditioner).
An automatic startup test is being per­formed (will last for about two minutes).
A self-diagnostic function is being per­formed to preserve the air conditioner. ∗ Do not attempt to make repairs your-
self. Turn the main switch off and con­tact the dealer from whom you bought the air conditioner. Provide him or her with the name of the unit and the in­formation displayed in the remote controller.
The following do not indicate any malfunction:
Odours: smells such as tobacco or cosmetic odours may persist after they have been sucked into the unit. Sound of liquid flowing inside indoor unit: this can occur during or after operation and is simply the sound of refrigerant being circulated inside the unit. Ticking sound coming from indoor unit: this can occur when cooling or heating has just begun or has just stopped. It is caused by the indoor unit shrinking or expanding slightly due to the change in temperature. The message “CENTRALLY CONTROLLED” appearing on the LCD panel: from time to time, this message may come up on the LCD panel. This does not indicate any malfunction.

• The compressor will not operate unless the power supply phase connection is correct.
• Grounding protection with a no-fuse breaker (earth leakage breaker [ELB]) is usually installed for D.
• The connection wiring between the outdoor and indoor units can be extended up to a maximum of 50 meters, and the total exten­sion including the crossover wiring between rooms is a maximum of 80 m.
Use flat cable (three core wires) for indoor and outdoor connection wiring, and connect the core wires in their line-up order to S1, S2 and S3 of the outdoor unit’s terminal board.

• This unit has the flared connections on both indoor and outdoor sides.
1) When using commercially available copper pipes:
• When commercially available copper pipes are used, wrap liquid and gas pipes with commercially available insulation materials (heat­resistant to 100: or more, thickness of 12 mm or more).
• The indoor parts of the drain pipe should be wrapped with polyethylene foam insulation materials (specific gravity of 0.03, thick­ness of 9 mm or more).

A Points for securing the grille B Points for securing the grille C Indoor unit D Ceiling surface E Drainage pan F Places for securing front grille G Make sure these surfaces are flush with each other (0-3 mm).
2) Checks before setting in place
• Before installing the front panel, make sure the indoor unit is square with the ceiling opening (or parallel to the angle between the wall and the ceiling).
• Check that the four points where the front panel will be secured are in contact with the ceiling surface (see figs. 1, 2).
• Check that the insulation for the refrigerant pipes, drainage pipes, etc. is in place and that wiring connections and arrangements are complete.
3) Installing the grille
• Open the intake grille by pressing on the place marked Push, and remove the air filter.
• Remove the screw cover in the middle of the blower.
• Open the upper and lower flaps on the indoor unit completely.
• Hook the temporary holding tabs on the front panel to the hooks on
the indoor unit (see figs. 3, 4).
A Hooks B Open the upper and lower flaps completely C Temporary holding tab D Temporary holding tab E Screw cover
• Adjust the front panel so that it fits properly in the angle between the ceiling and the wall, and install the securing bolts 2 (supplied with this grille) in their four places at left and right, leaving them slightly loose.
• Next tighten the securing bolts 2 and securing screws 3 in the center three places.
• Finally tighten the securing bolts 2 in the four places at left and right.
• At this point, make sure there are no gaps between the indoor unit
and the front panel, and between the front panel and the ceiling surface. If there are gaps, the wind may come in and it may cause water to drip (see fig. 5).
* Tighten the securing bolts 2 and securing screws 3 completely.
• Replace the air filter and screw cover, and press the intake grille on the place marked Push until you hear it snap into place.
A Hook D Temporary securing tabs
4) Checks after installing
• Check that there are no gaps between the indoor unit and the front panel, and between the front panel and the ceiling surface. If there are gaps, the wind may come in and condensation may result.
• Check that the air filter is in place.
