I would suggest Mondays. Every Monday the black refrigerator with 3 glass doors in the Pantry should be drained. In the picture below you see that I already have the louvered vent off of the front. It is held on by two plastic hooks that go over screws and two actual screws you have to take out. Very easy.
Here is what the screws look like that are taken out of the bottom left and bottom right side of the black louvered vent. The screws are found in the side right over the last vent in the cover.
Underneath we have a catch pan which is basically a plastic Cambro chafing dish. You can see in the picture below how the drain tube/hose comes down from the refrigerator unit. Most models have heat coils that evaporate the water so its usually not an issue in other refrigerators. This one does not have one. It was bought used, runs great, and otherwise has no problems. During the warmer and hot months this unit HAS TO BE DRAINED EVERY WEEK, NO EXCEPTION.
Here is a link to a printable form you can use to track and also to be a reminder.
Use a 5 gallon bucket to pour water into and then drain water in the mop sink in the kitchen.
Make sure you slide the plastic chafing dish back in and position the tube/hose inside so it will drain properly. This holds about 5 gallons of water before it start to overflow.
