Pre-Installation Instructions

Before you begin

Perform the following pre-installation steps:

Step Action

1 Ensure that your DLR-M system is correct for your flow capacity (see Flow Rate

Tables in Technical Specifications.)

2 Ensure that your water supply meets water quality standards as shown in the table

below. If any of the elements exceed the recommended maximum, we strongly suggest, at a minimum, that you install a 5-micron sediment filter as particles in the water can reduce UV light intensity and affect performance. Contact the distributor for additional information about testing and pretreatment equipment.

Suspended solids <5 mg/l Color None Iron 0.3 mg/l Manganese 0.05 mg/l pH 6.5 to 9.5 Hardness <120 ppm

3 Check the pressure of the water supply. The WEDECO UV system is designed to

Less than 148 psi Proceed to step 4 Greater than 148 psi Install a suitable pressure-reducing valve in

Note: All models are rated for a minimum UV transmittance of 70%. If your

transmittance is lower, consult the distributor.

operate at pressures up to 148 psi.

• The disinfection unit can be installed either horizontally or vertically. (See Figure

3 for water flow direction.)

• There must be enough clearance to remove the UV lamp and the quartz sleeve for

replacement and regular maintenance. Recommended clearance is length of unit plus four inches. (See Figure 4 for additional clearance requirements.)

• The unit must be within 7 feet of a properly grounded, dedicated 110V electrical

outlet. A 7'5" cord is included with the unit.

• The unit must be protected from freezing. Freezing damage will void the warranty.

• The unit should be placed where a potential leak will not cause water damage.

WEDECO is not responsible for water damage.

Figure 3: Unit Positioning

Figure 3 shows proper water flow for horizontal or vertical installation. Make certain that your unit and the inlet and outlet pipes are in the right position for either horizontal or vertical installation.

Correct Installation

IMPORTANT!

For vertical installation, the inlet is at the bottom and the outlet is near the top of the disinfection chamber. For horizontal installation pay careful attention to the diagram for flow direction.

Installing the Disinfection Unit

Attaching unit to wall

Follow these steps to attach WEDECO UV disinfection chamber to the wall.

Step Action Diagram

1 Install the two wall mount brackets on the

wall using the proper screws for your wall type (screws not included).

2 Place disinfection chamber in the brackets

and secure with the wall mount bracket straps. Use the wall mount bracket strap screws provided to tighten the wall mount bracket straps to the wall mount brackets.

3 The disinfection chamber must be properly

grounded prior to powering up the system. Attach the ground wire to the stud and nut located on the lower area of the disinfection chamber and connect it to the earth strap that is located at the bottom left of the electrical box. (Grounding wire included.)
