1. Introduction
Thank you for choosing the NEWBOLER Water Reservoir Hydration Pack. This manual provides essential information for the safe and effective use, care, and maintenance of your hydration bladder. Designed for outdoor enthusiasts, this BPA-free hydration pack is ideal for running, hiking, cycling, mountaineering, and camping.
The NEWBOLER hydration bladder is available in 1.5L, 2L, and 3L capacities, featuring a plug-and-play system, a specially designed automatic on/off valve, and a 105 cm long hose compatible with various cycling packs and hydration vests.

2. Setup and Filling
Before first use, and after each use, ensure the reservoir is thoroughly cleaned (refer to Section 4: Care and Cleaning Instructions).
- Open the Reservoir: Locate the Secure SlideLock mechanism at the top of the bladder. Slide it open to reveal the wide opening.
- Fill with Water: Pour your desired liquid into the reservoir. The wide opening makes filling convenient. Ensure the liquid temperature is within the recommended range of -20°C to 50°C (-4°F to 122°F). Do not use carbonated drinks or extremely hot/cold liquids.
- Seal the Reservoir: Once filled, slide the Secure SlideLock back into place, ensuring a leak-proof seal.
- Connect the Hose: Ensure the 100cm water pipe is securely connected to the bladder's outlet.
