Features and components

Measuring in at an impressive 10,000 BTUs, this Kenmore portable AC cools spaces up to 450 square feet and features several additional modes of operation.  In fan only mode, the air conditioner portion turns off so you can use the machine’s fan to circulate the air in your home. Dehumidifier mode gives you the chance to dry a space only, with continuous draining.  During sleep mode, the device turns off after a predetermined increment of time, giving you a chance to keep the machine on just long enough until after you’ve fallen asleep.

The unit also features automatic defrosting and a water pan overflow alarm that shuts off the system when the tank fills to the top.  The handy remote included snaps to the back of the machine for easy storage. Castors attach to the bottom of the unit to give it mobility.

Installation

The two primary components that need to be installed are the air exhaust hose and the drainage tube for optional continuous water draining.  Right now, we will look at installing the air exhaust hose.

First, start by connecting the air exhaust hose to the back of the air conditioner with the attached couplers.  Once attached, the joint can be further secured with a screw. Go ahead and screw in the castors to the bottom of the device before proceeding to the next step.  

Next, depending on whether you have a vertical opening or horizontal opening window, find the window slider and fit it inside the window frame.  Before putting the slider in place, cut a length of foam seal to fit the width of the window and attach it to the window sash. Then attach the slider.

Now take the exhaust hose and snap it into the window slider.  Close the window down firmly on top of the slider component, using the foam to create a tightly insulated seal.  

Getting started

When you plug the unit into a power outlet, you will hear a beep indicating the connection has been made.  Next, the screen will illuminate and the reading will indicate the current temperature of the room. Then, after pressing the power key, the air louvers on the front of the unit will open, signalling the start of the cooling mode.  

Using the control panel

Pressing the up or down keys will raise or lower the temperature, respectively.  The mode key selects between cool, dry (dehumidifier), and fan (fan-only) operation mode.  A fan key is included to adjust between different fan speeds while the timer key activates the programmable built-in shut off timer.

The timer key can be set to limit the run time hours in one-hour increments.  After manually selecting the desired run time, the unit will run until the set time and will then shut off completely.  There is also a delay start time setting where you can delay when the air conditioner turns back on from being off.  

Sleep mode gives you the power to let the air conditioner increase in temperature by one degree increments after you fall asleep.  The idea is to match how the body naturally cools as you fall asleep. The AC is the coldest as you lay down and gets slowly warmer the longer you are asleep.  This helps save on energy waste, especially since the middle of the night has the coolest temperatures of the full 24 hour day cycle.

Fortunately, all of these controls and features can be set and programmed from across the room, or across the house, with the included remote control.

Drainage

The air conditioner comes with a drainage tube for optional continuous draining functionality.  Otherwise, water collects in the water pan inside, necessitating regular emptying during heavy use.  Whenever the machine is draining into the internal water pan, a sensor watches for the water to reach a fill level, at which point an alarm will sound and the machine will shut down.  Place a water collection container underneath the bottom drain port in the back. Unscrew the drain cap and remove the water plug. Water will flow out the back of the machine and into your collection container until the water pan is empty.  Hit the power button to get the machine running again.

To utilize continuous drainage, you will have to attach the drainage tube to the middle drainage port on the back of the unit.  Once the tube is firmly inserted into the middle drainage port, take the other end of the drainage tube and set it into a water container or a floor drain for continuous draining.

Maintenance

You machine will need periodical cleanings both inside and out.  First, power off your machine and unplug it from the wall. Clean all exterior surfaces with a wet soft cloth, and avoid using chemicals like alcohol, bleach, or gasoline.  The use of chemicals and permanently damage the air conditioner coil.

You will also need to clean the two filter screens once every two weeks.  Both filters should be submerged and soaked in warm water with mild detergent.  After removing all dust and microbial build up, rinse each filter clean with plain water and dry before reattaching to the machine.

Troubleshooting

If problems occur during usage, refer to the troubleshooting guide at the back of the manual.  For instance, if the air conditioner is making a loud noise, it could be a result of not installing the machine on a flat surface.  If you’re experiencing diminished cooling power from the machine, it could be anything from too much direct sunlight on the machine to a dirty air filter restricting air flow.  

There are two error codes that might occur during normal use of the air conditioner.  If your display reads E1, that means the coil temperature sensor is malfunctioning. If it reads E2, that means the room temperature sensor is malfunctioning.  In both cases, you need to call Kenmore for professional service and repairs.

Safety warnings

There are several safety notices that are important to stay aware of.  Never connect the power cord to an ungrounded electrical outlet, or a standard extension not made specifically for high amperage appliances like portable air conditioners and dehumidifiers.

Be sure to never block air flow to the air conditioner, while always keeping furniture and items clear of the intake.  Also make sure the machine is sitting on a flat and level surface to prevent rattling and loud oscillations that can damage the internal components.  

Be sure to never operate the machine without both air filters firmly in place.  Both of these filters need to be cleaned or swapped out every two weeks. New filters can be purchased directly from Kenmore.

Improper installation could result in system failure, or in severe cases, fatal injuries.  Even if you’re confident you understand all of the safety precautions and think installation will be a breeze, it’s important to consult with a professional heating and cooling technician to prevent any serious or catastrophic problems before they occur.
