RO Filtration & UV Treatment

02

Multiple Layers of Treatment in One Portable System

The K8680 combines a reusable intake pre-filter, PP cotton, activated carbon, an RO membrane, and UV treatment. Each component performs a different role before purified water reaches the blue PURE outlet.

Complete System 10-Stage Water Treatment

Multi-stage treatment helps manage visible debris, sediment, taste, odor, dissolved solids, and microorganisms in outdoor freshwater sources.

Pre-Filter PP Cotton Activated Carbon RO Membrane UV Treatment Pre-Filter Stainless Steel Mesh

Helps block larger debris such as twigs, leaves, weeds, and other visible materials before water enters the system.

Reusable Large Debris Outdoor Intake Clean and maintain regularly Pre-Filter Layer Medical-Grade PP Cotton

Helps capture particles larger than 5 μm, including micro-sediment, rust, insect eggs, and mineral debris.

>5 μm Particles Rust Sediment Rated capacity: up to 500 gallons RO Cartridge Layer Activated Carbon

Helps reduce color, chlorine, unpleasant taste, odor, synthetic detergents, and selected organic substances.

Chlorine Reduction Taste Improvement Odor Reduction RO Cartridge Layer Reverse Osmosis Membrane

Supports high-precision purification and helps reduce dissolved solids, selected heavy metals, PFOA, PFOS, and other listed contaminants.

TDS Reduction RO Purification High Precision Rated capacity: up to 3,000 gallons Final Treatment UV Germicidal Lamp

Provides an additional treatment stage targeting bacteria and viruses while the system is operating.

UV Treatment Automatic Operation Service life listed as lifetime in the manual Filter life note: Actual cartridge life varies according to source-water quality, TDS level, sediment load, filtered volume, and maintenance. Monitor the purified-water TDS reading and replace the cartridge earlier when filtration performance decreases.

F Flush Automatic Cleaning

Automatic flushing starts when the purifier is powered on and finishes when the indicator turns off.

R Raw Water TDS Monitor Source Water

Displays the TDS level of the incoming raw water source.

P Pure Water TDS Monitor Filtered Water

Displays the TDS level of the purified water after filtration.

UV Sterilize UV Operating Status

The UV indicator remains on while the UV treatment system is operating normally.

W Produce Water Filtration Status

The water-production indicator remains on during normal filtration operation.

B Battery Remaining Power

Displays the remaining battery level for better outdoor-use planning.

A Full Water Pressure Valve Response

The built-in pressure valve responds when the purified-water outlet is opened or closed.

E1 Recondition Service Reminder

A flashing service light may indicate an internal component fault requiring inspection.

Hold 3 Seconds Power On or Off

Press and hold the main button for three seconds.

Press Once Start or Stop Filtration

Use one short press while the system is powered on.

Press Twice Turn the Light On or Off

Two short presses control the built-in work light.

Press 3 Times Turn SOS Mode On or Off

Three short presses activate or deactivate the SOS light.

Water Connections

05 White Pipe · RAW Draw Water from the Source

Connect the white pipe to the reusable pre-filter, place the intake in the raw-water source, and connect the opposite end to the RAW inlet.

Blue Pipe · PURE Collect Purified Water

Connect the blue pipe to the PURE outlet and direct it to the included faucet or a clean water container.

Red Pipe · DIRTY Drain Concentrated Water

Connect the red pipe to the DIRTY outlet and direct the opposite end to an appropriate drainage location.

Initial-use procedure: Check that all pipes and seals are securely installed. After inserting the RO cartridge, power on the system and allow it to operate for approximately 30–60 seconds to rinse the RO membrane before collecting drinking water.

Care, Replacement & Use Notes

06 01 Use Water Within the Recommended Range

Raw-water temperature should remain between 41°F and 100°F / 5°C and 38°C.

02 Operate in a Suitable Environment

Recommended environmental temperature is 40°F–104°F / 4°C–40°C.

03 Backflush the Pre-Filter Monthly

Regular pre-filter cleaning helps reduce blockage and supports more stable water intake.

04 Replace PP Cotton as Needed

The manual recommends replacement approximately every 3–6 months, depending on source water and usage.

05 Replace the RO Cartridge on Time

The manual recommends approximately every 6–12 months, or earlier when TDS rises or filtration performance declines.

06 Do Not Open or Wash the RO Cartridge

The RO cartridge is replaceable and should not be internally cleaned or disassembled.

07 Keep the Charging Port Dry

Do not pour water or other liquids into the Type-C charging connection.

08 Do Not Submerge the Machine

Clean the exterior carefully without immersing the electric purification system in water.

09 Avoid Abrasive Cleaning Materials

Do not use steel wool, abrasive cleaners, gasoline, acetone, or other corrosive liquids.

10 Prepare Properly for Long-Term Storage

Drain the system, remove the filters, allow all parts to air-dry, and store in a cool, dry place.

11 Residual Water Can Be Normal

A small amount of water may remain after factory pressure, water-flow, and UV testing.

12 Check Connections Before Every Trip

Inspect the cartridge, seals, quick-connect fittings, pipes, and outlets before operation.

Replacement guidance: Rated gallon capacity and recommended replacement months are reference values. Source-water quality, sediment, daily consumption, TDS level, temperature, and maintenance can shorten or extend the actual service period.
