•
The device is protected to IP 65.
•
The UVC device is rated for a nominal pressure of 6 bar. The unit may not be operated under pressure
exceeding 6 bar.
•
If parts of the device are damaged (particularly the quartz glass tube) the UVC device may not be
operated.

Installation
•
Remove the device from the box. Assemble the device and ballast using the brackets included.
Do not
open the ballast box! This will lead to an instant loss of warranty (security label).
•
Depending on the type of installation you should leave some space to exchange bulbs or quartz glass
tubes (two times the length of the device). If possible the device can be removed simply by loosening
the connection couplings.
•
Do not mount the ballast in a place exposed to direct sunlight, this
can lead to malfunction due to overheating.
•
Connect the supply and drain sides. Wrap Teflon tape
around the stainless steel outside threads of the device. Cover the
third connection opening with the PVC cap (rubber gasket). If in the
inflowing water stones or other hard particles are present, use as the
inlet one of the openings on the side of the reactor where a protective
steel sleeve protects the quartz glass tube.
•
Check the tightness of the system before turning on the
device.
•
Insert the 2-pin grounded plug
Device is warming up (orange
LED light)
after a few seconds the unit is in operation (green LED
lights up).
•
The
PURE 2.4 120 W should be installed horizontally in principle.
The types PURE 2.4 40 W and
PURE 2.4 75 W are recommended for horizontal installation, but a vertical installation in overhead lamp connection is possible. Be careful to
complete removal of the air inside of the plant.
•
If water stagnation is possible during the operation of the UVC device a protective system (not included) should be used which deactivates the
UVC device if the temperature rises above a certain threshold (recommendation: 40°C).

Maintenance
7.1
Lamp replacement
Always disconnect the main power plug before maintain the device!
•
Retract plastic cap (printed with safety labels). Loosen the three Allen screws in the black plastic cap with a 3mm Allen wrench.
•
After lifting the black plastic cap you can remove the green-yellow grounding conductor wire from the socket. Now gently pull the light bulb
attached to the white plug-in socket out of the housing.
•
If the lamp is pulled out a piece of the stainless steel housing, loosen the four-pin plug connection and replace the lamp with a new one.
•
Gently push it into the quartz glass tube inside the stainless steel housing. Avoid touching the light bulb with your skin. .
•
Re-attach the grounding conductor to the flat plug. Attach the black plastic cap with the three Allen screws. Make sure that the cap and the O-
ring seal are positioned properly and that the grounding conductor is not jammed.
•
Push the yellow plastic cap all the way forward onto the black plastic cap.
7.2
Quartz glass cleaning and replacement
Always disconnect the main power plug before maintain the device!
•
You should check on a regular basis (approx. 2 times a year) whether lime has built up on the quartz glass tube. Such build-up negatively
impacts the effectiveness of the device and must be removed.
•
Wear gloves and goggles when replacing the quartz glass tube.
•
Remove the UVC lamp as described in 7.1. . Remove stainless steel flange by loosening 3 Allen screws with a 4mm Allen wrench (There are
spring washers under the Allen screws heads.). You can now gently pull out the flange with the quartz glass tube.
•
Clean the quartz glass tube with a commercially available decalcifier. For quick and effective cleansing we recommend using a decalcifying gel.
After the exposure time of the decalcifying agent rinse the quartz glass with clear water and then wipe it off with a soft cloth. Avoid cleaning the
quartz glass tube with rough items.
•
Under normal circumstances the quartz glass tube must be replaced only when it’s damaged. The tube must be pulled from the stainless steel
connection gently and with a slight twisting motion (Wear gloves!)
