4. Installation
Follow these steps for proper installation of your AQUA CREST RV Water Filter:
- Identify Water Flow Direction: Locate the arrow on the filter body, which indicates the direction of water flow. Ensure the filter is installed so that water flows from the dirty water source (inlet) through the filter to the clean water outlet.
- Attach Hose Protector: Connect the flexible hose protector to the incoming water source (faucet or spigot). This protector helps prevent kinking and strain on the hose connection.
- Connect Filter: Attach the filter to the hose protector. Then, connect your garden hose or RV water inlet hose to the other end of the filter. Ensure all connections are hand-tightened to prevent leaks.
- Flush the Filter: Before first use, turn on the water slowly and allow it to run through the filter for a few minutes (approximately 5 minutes) until the water runs clear. This flushes out any carbon fines and prepares the filter for use.
- Begin Use: After flushing, the filter is ready for use.
