Quick guide from the manual
This solar shower is designed for outdoor use. It heats water using solar energy. The tank must be anchored to a stable, level surface before use.

Safety instructions
- Scalding risk: Water in the tank can become very hot in direct sunlight. Always test temperature before showering.
- Infection risk: Bacteria can multiply if the shower is unused for long periods. Drain the tank regularly.
- Frost protection: The product is not frost-proof. Dismantle and store in a dry, frost-free place if temperatures drop below 10°C.
Installation
The shower must be anchored to the ground. Use a second person to hold the shower while drilling and securing it to the floor. Tighten all connections by hand; using tools may damage the threads. If connections leak, use Teflon tape.
Operation
- Connect a garden hose to the adapter.
- Turn on the water supply. Set the faucet to "hot" to fill the tank (takes approx. 3 minutes).
- Once water flows steadily from the shower head, close the faucet.
- Adjust the temperature using the mixer faucet.
Maintenance and Troubleshooting
If water drips from the shower head after closing the faucet, this is normal due to thermal expansion in the unpressurized tank. If connections leak, apply Teflon tape to the threads. Drain the tank completely before winter storage.
