Connection, Installation of UV Water Filter at Home. UV Lamp Mounting and Usage Instructions - Nordic Tec

Selection of UV Water Filter for Home - Nordic Tec UV Water Sterilizers

First and foremost, if you have purchased a UV water filter with the intention of filtering or sterilizing water in your home (understood as the entire household), lamps in the range of 25W, 30W, or 55W are used for this purpose. These UV water filters are installed at the water inlet to the house, as close to the water source as possible, even within the building. Smaller UV lamps such as 16W, 11W, etc., will not suffice for sterilizing the entirety of water in a household.

UV lamps of 25W can be used in apartments or small cottages, conditionally - remembering that they must be properties with low water flows. It is also important to consider the fittings, which are typically 1/2" in size, often too small to sterilize water in a household where more than 1-2 people live.

Checking the Contents of the UV Lamp Packaging

After opening the box containing the UV water sterilizer, you should ensure that all components are included in the kit. This should definitely include the stainless steel sterilizer tube, two protective tubes made of thick cardboard (which should contain the UV-C bulb and the quartz sleeve), a power supply with a black electrical plug, an additional cable for the UV bulb (usually blue, occasionally another color), wall mounting brackets, and O-rings (silicone seals - at least 2 pieces).

Contents of the Nordic Tec UV Water Lamp Kit

1. Stainless steel tube (reaction chamber) - the main component of the UV water sterilizer, where the UV-C bulb, typically Philips, will be inserted. Water to be sterilized will flow through this tube.
2. Quartz sleeve (also called a quartz tube) - it will protect the UV bulb from water. Care should be taken to avoid breaking the sleeve, and it should be cleaned before installation, preferably free from dust, dirt, and fingerprints. Before installation, ensure that the sleeve is not cracked.
3. O-rings - silicone seals that will be placed on the quartz sleeve of our UV lamp. Without them, proper installation is not possible. Most of our lamp models require 2 seals (except for the smallest lamp models).
4. Second O-ring fitted on the opposite end of the quartz sleeve.
5. Open-ended cap/nut - for the stainless steel UV sterilizer tube. It will be attached from the side where the UV bulb will connect to the power supply. It has a hole inside for this purpose.
6. Closed-ended cap/nut for the stainless steel tube of our UV lamp kit - it will be mounted on the opposite end. It should be installed tightly - according to the art of sealing threads.
7. UV bulb, also referred to as UV-C bulb - we currently use Philips bulbs, produced in Europe, most often in Philips factory in Poland. In our current models, we offer UV bulbs with 2 pins on each side.
8. Socket for connecting the UV bulb. In the UV lamp models currently offered by Nordic Tec, an additional blue cable (sometimes of a different color) is included, which should be connected to this socket (there is a suitable slot). The connected cable will then allow for the connection of the second end of the bulb, as it has connecting pins on each end.
9. Socket cover. This is not a seal for the UV lamp, as many people initially assume. Sealing is provided by the O-rings and correctly installed nuts according to the art of thread sealing. The socket cover is intended to protect the bulb connection from dust and moisture in the air.
10. UV lamp power supply - also known as a ballast - with an electrical plug for connection to the 230V network. We remind you of the basic safety principle of UV radiation use - the UV lamp should only be switched on when the bulb is in the sterilizer (in the stainless steel tube) to avoid exposure of the eyes and skin to UV radiation.
11. Wall mounting brackets. The kit includes 2 pieces for hanging the UV lamp on the wall.
    ✅ IMPORTANT - THE BRACKETS SERVE ONLY AN AUXILIARY ROLE - the lamp must rest on rigid pipes. If you decide to mount it on hoses, which will additionally weigh it down, you must purchase additional mounting elements to secure the UV lamp tube to the wall.

1️⃣ Preparing the UV bulb and quartz sleeve - Beginning of UV Water Filter assembly

Handle the quartz sleeve and UV bulb with extreme caution.
✅ It is recommended to wear gloves to avoid leaving fingerprints on the glass. Clean the UV bulb and quartz sleeve with a lint-free cloth using clear alcohol. Fingerprints left behind can weaken the effectiveness of UV rays - and in the case of the bulb, may even lead to its rapid burning out. (A similar phenomenon occurs with car bulbs).

Once the UV bulb and quartz sleeve are clean, proceed with the assembly.

2️⃣ We prepare the reaction chamber - the stainless steel tube of the UV sterilizer

We start by unscrewing the nuts, which are usually supplied on the threads of the UV sterilizer. We unscrew both nuts - the open-ended and the closed-ended one.

Once we complete the task and the quartz sleeve is concealed inside the reaction chamber - our UV sterilizer - we will see a view similar to the one in the above picture. The quartz sleeve will not be fully concealed but will rest on the silicone seal. It is crucial that the seal is positioned at the correct distance from the edge of the glass tube. This ensures that the next step of UV lamp installation proceeds smoothly.

6️⃣We screw the closed nut onto the UV sterilizer

✅ We remind you to carefully seal the thread and to tighten it gently to avoid damaging the O-ring or the tube.

8️⃣Connecting the bulb to the UV water lamp | nordictec-store.com

Please remember that the UV lamp bulb should be thoroughly cleaned with a lint-free cloth and clear alcohol, and should not have fingerprints on the glass (as this can lead to rapid burning of the bulb - even shortly after it has been burned out). For this reason, it is recommended to use gloves - as shown in the attached photos in the instruction manual.

First, you should connect the blue cable to the bulb socket (there is a suitable plug there). Make sure it is securely connected to ensure a closed circuit. Then, insert the bulb into the socket from one side. Connect the 2 pins on the other side to the remaining end of the blue cable. In some kits, the cable may be a different color than blue - this has no technical significance, as the connection principle is the same. The bulb must be connected from both sides, otherwise it will not emit UV rays, and thus will not work.

At this point, we dispel doubts - many people ask whether the blue cable can be so close to the UV bulb, whether it will melt or be damaged by the temperature emitted by the UV rays. We assure you that this is a proven solution, used by our company since 2012. It is safe and does not pose a risk of damaging the cable, which is resistant to temperatures.

After correctly connecting the bulb from both sides, it will look like the one in the photograph below:
