Installation Guide for the HUUM Drop 6 Sauna Heater

Installing the HUUM Drop 6 Sauna Heater can be a straightforward process if you follow these steps carefully. Always remember to hire a licensed electrician for any electrical work and adhere to local building codes.

Step-by-Step Installation

  1. Unpack the Heater: Start by carefully opening the box. You’ll find the flue cap, stone basket cover, cables, salt spheres, stone baskets, and heat deflector.
  2. Prepare the Heater: Remove the lower stone basket and air tunnels surrounding the heating elements. Take off the front panel of the heater and unpack the telescoping flue. Detach the temperature sensor cable connected to the flue.
  3. Position the Heater: Place the heater on its back and remove the bottom panel. Feed the cables through the designated hole and connect them to the terminals according to the electrical diagram. Reattach the bottom panel once done.
  4. Install the Flue Cap: Mount the flue cap where the wall meets the ceiling. Assemble the telescoping flue and insert it into the heater’s flue socket, ensuring a snug fit.
  5. Secure the Heater: Hang the telescoping flue onto the mounted flue cap. Install the reflective plate on the flue behind the elements to help radiate heat into your room. Reattach the lower stone basket by hooking it behind the flue.
  6. Add the Stones: Carefully fill the lower basket with stones, ensuring they are not placed inside the air tunnels. Add the upper stone basket and continue filling it with stones.
  7. Final Assembly: Fasten the flue to the wall with screws, and place the cover plate into the slot at the top of the radiation plate. Install the protective grill over the stones. Set the salt sphere tray in place and add the salt spheres if included. Replace the front panel to complete the assembly.
  8. Electrical Connection: Ensure all electrical connections are secure and follow the manual for any additional wiring instructions. Remember to use the appropriate wire sizes and connectors as specified.
  9. Testing: Once installed, test the heater to ensure it operates correctly. Use the air blending valve to tailor the blend of air and oxygen inside your sauna room.
