Drain Pump (Optional)
A drain pump allows continuous operation and eliminates the need for drain tanks.
•When the water collects to level (A) in the pump reservoir, the drain pump begins to operate and
discharges the water. | B | A |
• When the water level drops below level (B), the |
| |
drain pump will stop. |

•If for any reason the water level exceeds that of level (A) in the pump reservoir, an overflow
Drain Switch will stop the compressor operation.
•If the Fan Mode Control DIP Switch (see pg.5) has been set operate from the STOP position,
the Fan will also turn off while the drain pump is discharging water.
DAILY INSPECTION & MAINTENANCE
Emptying the Drain Tank
To empty the drain tank, refer to instructions, page 14.
Cleaning the Air Filters
Clean the air fi lters once a week. If the unit is used in a dusty environment, more frequent cleaning may be required.
A dirty air fi lter reduces air output resulting in a decrease of the cooling capacity.
Filter Removal Method
➀Turn the unit off, by pressing the COOL ON/OFF button. If a program is running, you must fi rst press the Program RUN button.
➁Remove the 2 air fi lters.
NOTE: To remove the filters from the Office Pro 36, open the front panel and side
panel filter doors. Unclip the wire frame and remove filter.
