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.

PART NAMES AND FUNCTIONS

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 light-
est 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.
