This document describes the VEVOR UV-C Pond Bio Pressure Filter, a water filter designed for biological and mechanical cleaning of pond water.
Function Description
The VEVOR UV-C Pond Bio Pressure Filter is a sealed pressure filter system with an integrated UV-C clarifier. It is designed for biological and mechanical filtering of normal pond water, suitable for garden ponds with or without pond fish. The filter operates continuously, 24 hours a day, to ensure clear and healthy water.
The filtration process involves several stages:
- Water Inlet (A): Water from a pump is connected to the water inlet via a pressure hose.
- Vortex System (B): Under the action of gravity, suspended solids and mud are separated from the water.
- Mechanical Filtration (C): Water passes through filter sponges, where dirt particles are stopped by the sponge surface.
- Biological Clarifying (D): The filter sponges have pores that form a large inner surface for microorganisms to colonize. Blue filter sponges, with a high flow speed, favor the colonization of microorganisms that convert ammonium to nitrate (nitrification). Yellow sponges, with a low flow speed, support anaerobic microorganisms that reduce nitrate to nitrogen (denitrification). Biological materials also help cultivate anaerobic bacteria that turn nitrate into ammonia gas. (Note: The CPF-2500 model does not contain biochemical materials).
- UV-C Filtration (E): As water flows out, it is briefly exposed to ultraviolet radiation from the UV lamp. This kills germs and bacteria and inhibits algae growth.
- Water Outlet (F): The clarified water is fed back into the garden pond via a pressure hose or watercourse.
- Cleaning Connection (G): A drainage hose can be connected to this outlet to divert dirty water to a sewerage system or flower bed during cleaning.
The device features a function switch (H) to toggle between normal water discharge ("filter" position) and the cleaning connection ("clean" position). A cleaning handle (I) allows for mechanical cleaning of the sponges when the function switch is in the "clean" position. The UV timing switch (J) allows setting the UV lamp operation to OFF, 12, or 24 hours.
Important Technical Specifications
The manual provides specifications for three models: CPF-2500, CPF-3500, and CPF-10000. All models operate on 110-120V/60Hz and use a 13W UV-C lamp.

The filter is designed for pond water temperatures between +39.2°F and +95°F. The internal pressure should not exceed 0.3 bar.
Usage Features
- Integral Filter System: Provides remarkable filtering effect.
- UV-C Clarifier with Timer: The UV lamp can be set to OFF, 12, or 24 hours, improving water quality and ensuring clarity. Recommended settings are 24 hours in summer and 12 hours in spring and autumn. The UV lamp can be turned off in winter or when the filter is first started.
- Patented Cleaning Technology: Facilitates easy maintenance.
- Installation: The filter should be installed safely from flooding, at least 6.56 ft from the pond edge. It can be placed in a strong, smooth location or in a dug hole below the clamp/clip level. Ensure the lid can open for maintenance. For pumping heights over 3.28 ft, a more powerful pump is recommended.
- Hose Connection: Hoses should be warmed with hot water, pushed onto the spiral stepped hose adapter, and secured with a hose clip for a watertight connection. Larger diameter hoses are recommended. For hoses longer than 13.12 ft, use hoses corresponding to the upper scale value. Cut the spiral stepped hose adapter at relevant points to avoid pressure loss.
- Starting the Filter: Before start-up, check hose connections and clamp. The function switch must be set to "filter." The UV lamp must not be operated without water flowing through it. All sealing connections should be checked for leaks. The filter system with integrated UV must run permanently, 24 hours a day.
Maintenance Features
- Regular Cleaning: The filter system must be cleaned regularly. Filter sponges should be cleaned weekly, or when cloudy water flows from the outlet. The red indicator in the function switch will float when cleaning is needed.
- Washing Filter Sponges: To wash, turn the function switch clockwise to the "clean" position. Turn the cleaning handle to squeeze the sponges for mechanical cleaning. Rinse until clean water is seen through the transparent hose adapter. Then, turn the switch anti-clockwise back to "filter."
- Replacement of Filter Sponges: If water flow remains too small after cleaning, filter sponges must be washed or replaced. Disconnect the filter's mains plug and turn off the pump. Remove hoses, protective buckle, and open the clamp. Lift the lid with the sponge assembly. Remove the diversion pipe, screws on the gear, and separate plate. Remove and clean sponges under flowing water, squeezing them well. Clean the container, O-ring, and container edge. Reassemble by placing the sponge part on a separate plate, fixing the lean gear set, and fastening the diversion pipe. Place the O-ring (wet for easy fit) on the container edge and press down the lid. Secure the clamp and safety latch. Fasten all hoses.
- Cleaning the Quartz Tube and Replacing the UV Lamp: Unscrew the lid screw and pull out the UV head. Clean the quartz glass tube with a wet cloth. Remove the fixing nut and pull out the quartz glass tube to replace the UV lamp. Check the quartz glass tube set for breakage and replace if necessary. Reassemble all parts and restart the filter.
- UV Lamp Replacement: The UV lamp must be replaced after 8,000 hours of operation to maintain optimum effectiveness.
- Storage: To prevent frost, drain the water, clean, and check the filter after use. Store in a dry place.
Safety Instructions
- The device is a stationary UV-C clarifier. Unintended use or damage to the housing can lead to dangerous UV-C radiation, which can harm eyes and skin. Do not operate damaged appliances.
- Not for use by children under 16 or individuals with impaired physical, sensory, or intellectual abilities, or those unfamiliar with the instructions, unless supervised or trained.
- Electrical installation must comply with domestic provisions.
- Extension cables and adapters must be suitable for outdoor use to prevent water splashing.
- The filter UV must be equipped with a fault current protection switch (FI or RCD) with a measured fault current not greater than 30mA.
- Power supply connection wire section must not be lower than SJTW rubber cable.
- Seek help from electrical professionals for problems.
- Supply electrical data must match the label.
- UV rays are harmful to eyes and skin; never operate the lamp outside the container.
- Do not operate if the connecting cable, UV lamp, or shell is broken.
