Operation (continued) Alarm When the water tank is full, the unit will display the message "E4" on its screen. To resume normal function, turn the unit off, remove the drainage plug and drain the excess water from the unit. Replace the plug and turn the unit on to begin cooling. Maintenance Periodic maintenance extends the unit's lifespan and permits maximum operating efficiency. Replacing the Air Filters The SRCOOL18K and SRCOOL24K use replaceable air filters available for purchase at your local hardware or home improvement store (two per front and rear panel, see below for filter dimensions). It is important to keep the air filters clean and free of dust. When the filters are dirty or clogged with dust, it decreases cooling efficiency and can threaten air quality. Tripp Lite recommends cleaning the filters at least once every two weeks. Filter Replacement (Front and Rear Panels) 1 Remove the panel by lifting it up by its sides to disengage from the unit, then pulling away to detach. 2 On the inside of the front panel, replace both of the used filters with two new filters A (see table below for filter dimensions). 3 To reattach the panel, align the panel hooks B with the unit's slots C , push in to engage, then push down to secure the panel to the unit.

There is a risk of electric shock while the unit is plugged in. 1. Turn the unit off and unplug it. 2. Wipe the unit with a dry, non-abrasive cloth. Do not use gasoline, benzene, thinners or other harsh chemicals that may damage the surface. Do not pour water directly over the unit or into the working parts. This causes a risk of electrical shock and deterioration of electrical components and wiring insulation. 3. In extreme cases, wipe the unit with a damp cloth to remove residue. 11
