Only certain products are compatible with a separate faucet installation option.

• Installation of a separate faucet requires a down payment of $100 and an additional $3 dollars added to your monthly rental fee.
• If your water purifier is already installed, you will be charged $30 for the installation service for the faucet.

• If the water from a direct-flow purifier appears white, it is caused by air dissolved in the water.
• This happens when tap water passes through the filters and small air bubbles form due to pressure differences. These bubbles naturally disappear after a short time.
• Upon analysis, the cloudy appearance was confirmed to be caused by tiny air bubbles and contains no harmful substances to the human body.

• When you boil tap water in a kettle, you may notice white particles collecting at the bottom of the kettle.
• These particles are formed when naturally occurring minerals in the water bind together after being exposed to heat.
• The white substances that appear when boiling purified water are the same minerals that appear when boiling tap water. This is because the purifier removes impurities but allows beneficial minerals to pass through.
• The amount and type of minerals can vary depending on the local water source.
• Most of the sediment found in water purifiers is composed of natural minerals, such as calcium and magnesium. According to FDA standards, these inorganic minerals are considered safe and are recognized as normal components of drinking water when present at appropriate levels. Therefore, the presence of sediment does not necessarily indicate a “water quality issue.” In fact, it may simply be a sign that natural minerals are present.

Your water may taste off right after a filter replacement. This is because new filters are vacuum sealed and stored. In order to prevent this, we recommend that you flush the new filters out with room temperature water for at least ten minutes, and wait a few hours before dispensing water to drink.

Take the following steps to correctly store your water purifier for prolonged periods of time:

• Close the valve on the water purifier.
• Close the inlet valve.
• If your product has a tank, completely drain the water.
• Unplug the power cord and store in a dark, dry place.
• When using the product after it has been stored for a prolonged period of time, flush the product for at least ten minutes before use.

You can have a CUCKOO water purifier installed as long as you are requesting installation in a CUCKOO service area. However, you can only have RO water purifiers installed.

Visit the CUCKOO Rental America Official Website and click “Manual → Water Purifier Support" to watch how to replace a filter.

The filter replacement cycle can be found on the “Filter Replacement Self-Check Sticker” on the product. Additionally, you can find a replacement cycle guide in your replacement filter shipments.
