Mavrik H981 Ice Machine Filter Cartridge Instruction Manual

1. Product Overview

The Mavrik H981 Ice Machine Filter Cartridge is a high-quality replacement part designed to provide clean, clear water for ice machines. This cartridge is an exact fit equivalent to the 3M Cuno H981 and replaces Everpure MH Coffee cartridges, including model QC7I-MH and part number 76-1173. It is engineered to reduce taste, odor, and scale, ensuring optimal ice quality and machine performance. The filter operates at a 1-micron filtration level.

2. Setup and Installation

Proper installation of the Mavrik H981 filter cartridge is crucial for effective filtration and to prevent leaks. Always refer to your ice machine's specific manual for detailed instructions on filter replacement, as procedures may vary.

1. Safety First: Before beginning, ensure the water supply to the ice machine is turned off. Relieve any pressure in the system by opening a nearby faucet or dispensing water from the machine.
2. Locate Filter Housing: Identify the existing filter housing. It is typically located near the water inlet of the ice machine.
3. Remove Old Cartridge: Depending on your system, twist the old cartridge counter-clockwise or follow the manufacturer's instructions to release it. Be prepared for some water spillage.
4. Prepare New Cartridge: Remove the new Mavrik H981 cartridge from its packaging. Ensure all protective caps or seals are removed.
5. Install New Cartridge: Insert the new cartridge into the filter head. Align the cartridge with the head and twist clockwise until it is securely seated. Do not overtighten.
6. Restore Water Supply: Slowly turn on the water supply to the ice machine. Check for any leaks around the filter housing.
7. Flush the System: Run water through the system for several minutes (e.g., 5-10 minutes) to flush out any air or carbon fines from the new filter. This may involve dispensing water or allowing the ice machine to cycle. Discard the first few batches of ice.
8. Check for Leaks: After flushing, re-check for any leaks. If leaks persist, ensure the cartridge is properly seated and tightened.

3. Operation

The Mavrik H981 filter cartridge operates passively within your ice machine's water supply system. Once installed, it continuously filters incoming water, removing impurities to improve the taste and quality of ice, and to protect the machine from scale buildup. No user interaction is required during normal operation.

4. Maintenance

Regular replacement of the filter cartridge is essential to maintain optimal water quality and system performance.

• Replacement Schedule: Filter cartridges should typically be replaced every 6 to 12 months, or sooner if you notice a decrease in water flow, a change in ice taste/odor, or if your ice machine's indicator light signals a filter change is needed. Actual replacement frequency depends on water quality and usage volume.
• Storage: Store new, unused cartridges in a cool, dry place away from direct sunlight and chemicals.

5. Troubleshooting

If you encounter issues after installing the Mavrik H981 filter, consider the following:

• Reduced Water Flow: This could indicate a clogged filter, especially if it's nearing the end of its service life. Ensure the filter is correctly installed and not overtightened. If the issue persists, the filter may need replacement.
• Unusual Taste or Odor in Ice: This suggests the filter is no longer effectively removing impurities. It's time to replace the cartridge. Ensure the system was properly flushed after the last installation.
• Leaks: Turn off the water supply immediately. Check that the filter cartridge is fully and correctly seated in the filter head. Ensure the O-rings are not damaged or missing. Re-install the cartridge carefully.
