4. Installation and Setup
The AP1-P system is designed for easy installation and can be wall-mounted. Professional installation is recommended to ensure proper function and compliance with local plumbing codes.
4.1 Pre-Installation Checklist
- Verify water supply pressure is within the recommended range for your ice machine.
- Ensure adequate space for installation and future filter replacement.
- Gather necessary tools (e.g., wrench, drill, mounting hardware).
4.2 Installation Steps
- Turn off the main water supply to the ice machine.
- Mount the filter head securely to a wall stud or suitable support structure using appropriate mounting hardware (not included).
- Connect the water inlet line to the "IN" port of the filter head and the outlet line to the "OUT" port, leading to the ice machine. Ensure all connections are tight.
- Insert the filter cartridge into the filter head by aligning the cartridge with the head and twisting until it locks into place.
- Slowly turn on the water supply and check for leaks. Flush the system by running water through it for several minutes to remove air and carbon fines.
- Verify the pressure gauge reading is stable and within the normal operating range.
5. Operation
Once installed, the Scotsman AP1-P system operates continuously to filter water supplied to your ice machine. The integrated pressure gauge allows for monitoring of water pressure, which can indicate filter life or system issues.
- Regularly check the pressure gauge. A significant drop in pressure may indicate a clogged filter requiring replacement.
- Ensure the shut-off valve on the filter head is in the open position during normal operation.
6. Maintenance
Regular maintenance of your filtration system is crucial for optimal performance and extending the life of your ice machine.
6.1 Filter Cartridge Replacement
The filter cartridge should be replaced every 6-12 months, or sooner if a significant drop in water pressure or a noticeable change in ice quality occurs.
- Turn off the water supply to the filtration system using the shut-off valve on the filter head.
- Relieve any residual pressure by briefly opening a downstream faucet or valve.
- Twist the old filter cartridge counter-clockwise to remove it from the filter head.
- Discard the old cartridge responsibly.
- Insert the new Scotsman replacement filter cartridge into the filter head, aligning it correctly, and twist clockwise until it locks securely.
- Slowly turn on the water supply and check for leaks. Flush the new filter by running water through it for several minutes.
6.2 System Cleaning
Periodically inspect the filter head and connections for any signs of wear or damage. For comprehensive system maintenance, consider using Scotsman Clear 1 Scale Remover and Scotsman ice machine cleaner products as part of your routine.
