Setup and Installation
Pre-Installation Checklist
- Ensure adequate space for installation and future maintenance.
- Verify that the incoming water supply pressure is within acceptable limits for the system.
- Confirm that a grounded 115V AC electrical outlet is available.
- Gather necessary tools: wrench, pipe sealant/Teflon tape, screwdriver.
Mounting the System
The system should be mounted vertically on a sturdy surface using appropriate fasteners. Ensure the unit is level and securely attached to prevent vibration and noise.
Plumbing Connections
- Identify the water inlet and outlet ports on the system.
- Apply pipe sealant or Teflon tape to all threaded connections.
- Connect the incoming water supply line to the system's inlet port.
- Connect the system's outlet port to the equipment requiring boosted water pressure.
- Ensure all connections are tight to prevent leaks.
Electrical Connections
- Ensure the system is properly plumbed and free of leaks before connecting power.
- Plug the system's power cord into a grounded 115V AC electrical outlet.
- The system will automatically begin to pressurize once power is supplied.
Initial Startup
- Slowly open the water supply valve to the system.
- Open a downstream faucet or valve to allow air to purge from the system.
- Once a steady stream of water flows, close the downstream faucet.
- Check all connections for leaks.
Operation
The SHURflo Mini Water Boost System operates automatically. When water is drawn from the system, the pressure switch detects a drop in pressure and activates the pump to maintain the desired output pressure. When water flow stops, the pump will shut off once the system reaches its set pressure.
- The system is designed for intermittent duty. Avoid continuous operation for extended periods without flow.
- The integrated tank helps to reduce pump cycling and maintain stable pressure.
Maintenance
Routine Checks
- Monthly: Inspect all plumbing connections for leaks.
- Quarterly: Check the system's mounting for security and ensure no excessive vibration.
- Annually: Verify the system's performance by checking output pressure.
Cleaning
Clean the exterior of the unit with a damp cloth. Do not use abrasive cleaners or solvents. Ensure no water enters the electrical components.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System does not turn on | No power supply Faulty electrical connection | Check power outlet and circuit breaker Ensure power cord is securely plugged in |
| Low or inconsistent water pressure | Insufficient incoming water supply Air in the system Clogged lines/filters (if applicable) | Verify adequate incoming water flow Purge air from the system (see Initial Startup) Inspect and clean/replace any pre-filters |
| System runs continuously | Leak in plumbing Constant water demand | Inspect all connections and plumbing for leaks Ensure all downstream faucets/valves are closed when not in use |
| Excessive noise/vibration | Loose mounting Air in the system | Tighten mounting fasteners Purge air from the system |
