It is recommended that the height of the heating unit and mat are leveled for smooth water circulation in the early stages of use and installation. In case of using it afterwards, if the height of the bed is less than 1m(3ft), you can place the heating unit lower than the mat. 

The slim type mats are very thin, less than 2mm in size, so you can feel the cushioning feeling of the mattress when you use it on the bed. When using the product on the floor, it is recommended to use a thick mat or blanket to prevent heat loss.

Navien Mate is a bed warming mattress topper that provides warmth for comfort. Dual temperature control is possible by individually adjusting the left and right temperature in 1°F increments.

The separate heating function is optimized for use at temperatures (shown below) recommended. The recommended water temperature for each mat type is 95°F (35°C) above the cushion mat and 91°F (33°C) above the slim mat.

If you set the temperature to be lower than the recommended water temperature, when using separate heating, the mat temperature may be affected by your body temperature (98°F/37°C).

Navien Mate recommends placing the heating unit at your feet. The head of the mat is the side without a hose and the foot is the side connected to the hose and heating unit. When you look at the mattress topper from the foot of the mat, you can see the left and right label.

By heating the heating unit and the water inside the mat at high temperature, it can sterilize bacteria and microorganisms, so you can rest assured without worrying about harmful bacteria. It is recommended to use sterilization mode once a month. Do not lie on the bed warmer pad during sterilization mode.

  1. Touch and hold for 2 seconds the sterilization button on the control panel of the heating unit. The sterilization lamp will light, and sterilization mode will be activated.
  2. The sterilization mode is 30 minutes long, and the power is automatically turned off after the sterilization mode is completed.

The first time you install the unit, it will take 15-20 minutes. After that, it usually takes 5-10 minutes for the temperature to reach 37°C.

You can use drinking water or tap water instead of distilled water. We recommend using purified water as much as possible.

Remove the water according to the instructions in the user manual, and store it according to the following method.

  1. Heating Unit
    Keep the heating unit dry in the shade, ventilated and out of direct sunlight. (It is recommended that you save the residual water removal kit and instructions together to prevent loss.)
  2. Mat
    If you do not use the Navien Mate, please spread the mat and keep it in a room as it is, or fold and keep it in a comfortable place according to your preference. If any stains are found, rub lightly, then wipe with a soft cloth. Use of washing machine is prohibited.
    If you use the storage bag provided at the time of purchase, you can keep it clean and convenient.
  3. Cover
    The cover can be used as a bed pad throughout the year after being separated from the mat. The cover is 100% cotton. Please place the cover in a laundry net bag before machine washing cold on a delicate cycle. Please use a neutral detergent. Hang dry. Do not tumble dry.

The sterilization mode will briefly boil the water in the heating unit and in the hose to quickly kill germs. We recommend doing this once a month. Do not lie on the bed warmer pad during sterilization mode.

Navien Mate conducts pre-inspections of all products before leaving the factory, but if there is a leakage problem on your product, discontinue use and contact Navien Mate Customer Service Center.

The connector guard prevents contact with hot components. When the heating unit is tipped, the balancing sensor automatically turns the system off and the overflow prevention filter prevents water spilling. The heating unit will automatically shut down after 15 hours of continuous use. When room temperature drops below 41°F (5°C), the system will automatically activate to prevent water from freezing in the system.    

Refill time varies depending on the indoor environment (temperature and humidity) and customer use (temperature setting and hours of use). In general, if the system is set at 99°F (37°C) and used for 8-10 hours per day. Water should be filled higher than medium level bars for continuous and safe heating. Do not overfill.

  1. Touch the hose connector bracket (white plastic case) of the mat to check warmth. If the connector is not warm, reconnect the mat and hose connections until you hear “click” sound.
  2. If the cushion type mat is folded in the same shape for a long time, the hose may partially stick to each other, and then the water circulation may not be smooth. However, it can be restored naturally after 1 to 2 days of use. Please refer to Tip below to help restore hose faster.
    Tip for faster hose restoration
  • Set the heating unit and mat to the same position horizontally and set to the maximum temperature.
  • Use the residual water removal kit provided to inject air.

    2. Insert the pump into the non-heating side and inject air about 10 times.

If you use other equipments, such as a bicycle pump, not supplied, and inject air, the mat can be damaged.
