3. Produktet er slutview
The Carvin Laser Sand Filter system consists of a durable filter tank and a versatile 7-way dial valve. Understanding its components and functions is key to effective pool maintenance.
Figure 3.1: Complete Filter Assembly. This image displays the full Carvin Laser 25-inch sand filter unit, including the main filter tank and the top-mounted 7-way dial valve with its pressure gauge. The robust, blow-molded tank is designed for durability and resistance to UV and corrosion.
3.1. 7-Way Dial Valve Functions
The filter's 7-way dial valve allows you to select various operational modes for your pool system. The functions are clearly marked on the valve's top.
Figure 3.2: Valve Function Diagram. This image shows the circular dial of the 7-way valve, illustrating the different operational settings: Filtration, Backwash, Rinse, Whirlpool, Drain, Winterize, and Test. Each setting is clearly labeled for easy selection.
- Filtrering: Normal filtering mode. Water passes through the sand bed, removing debris.
- Tilbageskylning: Cleans the filter by reversing water flow, flushing trapped debris out of the waste port.
- Skylle: Used after backwashing to settle the sand bed and flush any remaining dirty water to waste before returning to filtration.
- Whirlpool (Recirculate): Omgår filteret og cirkulerer vandet direkte tilbage til poolen. Nyttig til at blande kemikalier uden filtrering.
- Drain (Waste): Drains water directly from the pool or spa to waste, bypassing the filter. Useful for lowering water level or vacuuming heavy debris directly to waste.
- Vinterklar: Position for preparing the filter for winter storage, typically used to drain the filter tank.
- Prøve: A specific setting for pressure testing or other diagnostic purposes.

4. Opsætning og installation
Proper installation is crucial for the performance and safety of your Carvin Laser Sand Filter. Follow these general guidelines. Refer to a professional if unsure.
4.1. Valg af sted
- Choose a level, solid surface, preferably concrete, capable of supporting the weight of the filter filled with sand and water.
- Locate the filter as close to the pool as possible to minimize pipe friction loss.
- Ensure adequate clearance around the filter for maintenance and servicing.
- Protect the filter from direct sunlight and harsh weather conditions if possible.
4.2. Filling with Filter Media (Sand)
- Remove the 7-way valve and place a sand guard (if provided) or a plastic bag over the standpipe to prevent sand from entering it.
- Fill the tank approximately halfway with water to cushion the sand as it is added.
- Carefully add the correct grade and amount of filter sand (typically #20 silica sand) into the tank. Refer to your filter's specifications for exact sand requirements.
- Remove the sand guard/plastic bag and ensure no sand is in the standpipe opening.
4.3. Valve and Plumbing Connections
- Carefully place the 7-way valve onto the filter tank, ensuring the standpipe aligns correctly with the valve's opening.
- Secure the valve to the tank using the noncorrosive resin clamp. Sørg for at clamp is tightened evenly and securely.
- Connect the plumbing from your pool pump to the "PUMP" port on the valve.
- Connect the plumbing leading back to your pool returns to the "RETURN" port on the valve.
- Connect a waste line to the "WASTE" port on the valve. This line should lead to an appropriate drainage area, observing local codes.
- Install the pressure gauge into the designated port on the valve.

5. Betjeningsvejledning
Before operating, ensure the pool is filled to the proper level and all plumbing connections are secure. Always turn off the pump before changing the valve position.
5.1. Indledende opstart
- Ensure the filter tank is filled with sand and water.
- Set the 7-way valve handle to the BAGSKYLNING position.
- Turn on the pool pump. Backwash for 2-3 minutes or until the water in the sight glass (if present) runs clear.
- Sluk for pumpen.
- Set the valve handle to the SKYLLE position.
- Turn on the pump. Rinse for 30-60 seconds.
- Sluk for pumpen.
- Set the valve handle to the FILTRATION position.
- Turn on the pump. Note the initial pressure gauge reading. This is your clean filter operating pressure.
Figure 5.1: Pressure Gauge Detail. This close-up image shows the pressure gauge mounted on the 7-way valve. Monitoring this gauge is essential for determining when backwashing is required, typically when the pressure rises 8-10 PSI above the clean operating pressure.
5.2. Normal Operation (Filtration)
Keep the valve in the FILTRATION position for daily pool operation. Monitor the pressure gauge. When the pressure rises 8-10 PSI above your clean operating pressure, it's time to backwash.
5.3. Changing Valve Positions
Always turn off the pool pump before moving the 7-way valve handle to a different position. This prevents damage to the valve's internal components and ensures safe operation.
6. Vedligeholdelse
Regular maintenance ensures optimal performance and extends the life of your Carvin Laser Sand Filter.
6.1. Backwashing
Backwash your filter when the pressure gauge reads 8-10 PSI above the clean operating pressure, or when the pool water appears cloudy despite adequate filtration time. Follow the steps outlined in Section 5.1 (Initial Startup) for backwashing and rinsing.
6.2. Vinterklargøring
For colder climates, proper winterization is essential to prevent freeze damage.
- Sluk pumpen og afbryd strømmen.
- Set the 7-way valve to the VINTERISER position.
- Open the bottom drain plug on the filter tank to completely drain all water.
- Remove the pressure gauge and store it in a warm, dry place.
- Drain all water from the pump, heater, and all plumbing lines.
- Cover the filter to protect it from the elements.
6.3. Sandudskiftning
Filter sand typically lasts 3-5 years, depending on usage and water chemistry. Over time, sand particles can become smooth or clumped, reducing filtration efficiency. Replace the sand when you notice persistent cloudy water or significantly reduced flow despite regular backwashing.
7. Fejlfinding
This section addresses common issues you might encounter with your sand filter.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Low Water Flow / High Pressure | Clogged filter sand; clogged skimmer/pump basket; closed valve. | Backwash and rinse filter; clean skimmer and pump baskets; ensure all valves are open. |
| Grumset poolvand | Insufficient filtration time; dirty filter sand; improper water chemistry; damaged laterals. | Increase filtration time; backwash/rinse filter; check and adjust water chemistry; inspect laterals for damage (requires sand removal). |
| Water Leaking from Valve | Worn O-rings/gaskets; loose clamp; cracked valve body. | Inspect and replace O-rings/gaskets; tighten clamp; replace valve if cracked. |
| Sand Returning to Pool | Damaged laterals; too much sand; incorrect sand type. | Inspect and replace damaged laterals; ensure correct sand volume and type. |
