Condensate Drainage; User Guide - York YM 09 V6 G Technical Manual

The fan propeller on the outdoor side of the unit has a lip at its
outer edge that projects condensates onto the condenser coil.
Heat produced by the coil evaporates the water. This increases
cooling and heating performances and eliminates the need to
install a condensate evacuation line (operating limit : 85 to 90%
humidity level).
Install the overflow on YO 12-19-24 units.
CAUTION : Each time the unit is stopped manually, wait at least three minutes before starting it again.
1 - Fan speed selection
The unit can be operated in ventilation only mode (i.e. without
heating or cooling). Use the fan selector
For air circulation in the Heating or Cooling modes, set the fan
speed selector to I (low speed), II (medium speed), III (high
speed).
Blue lines correspond to operation in cooling mode, red lines
correspond to operation in heating mode.

You may select either Heating or Cooling mode or the Ventilation
only mode.
3 - Thermostat
Adjust the thermostat to the setting that provides the highest
level of comfort heating or cooling. Higher numbers provide
lower room temperatures, lower numbers provide higher room
temperatures.
To reduce the temperature in the conditioned space (cooling
mode), turn the thermostat button clockwise.
To increase the temperature in the conditioned space (heating
mode), turn the thermostat button counter-clockwise.
4 - Air-Sweep Mode
When the Air Sweep mode is activated, the air flow is automati-
cally swept from left to right. If you want the air to be blown in a

particular direction, simply switch off air sweep just before it
reaches that position.
For vertical adjustment, move the horizontal deflectors manually.
5 - Ventilation
The unit either recycles indoor air (closed position) or exhausts
air outdoors (open position). Use the closed position when a
substantial amount of cooling is required. The closed position
can also be used to recirculate indoor air when using the
Ventilation Only mode. The closed position should be used to
obtain maximum heating on the heating/cooling model.
The open position enables removal of stale air from the room by
exhausting it outdoors. Fresh outdoor air is drawn into the room
through the normal air passages found in most buildings.
