Pre-Installation Instructions

IMPORTANT

Please read before installing your Ultraviolet System

When this unit is wired in conjunction with another electrical devise you may experience a drop in voltage. It is recommended that your Ultraviolet System NOT share a circuit with another electrical device. The maximum voltage threshold for this system is 130V. The minimum voltage threshold for this system is 105V. Please ensure that proper voltage requirements are meet before installing your Ultraviolet System.

Please read before installing your Ultraviolet System

IMPORTANT

Before you begin

Perform the following pre-installation steps:

Step Action

1 Ensure that your DLR 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

5 Select a location that meets the following guidelines.

x The unit must be installed between the cold water source and the water heater as

inlet temperature must not exceed 100

F. (See Figure 1 for proper installation

sequence.)

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

3 for water flow direction.)

x 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.)

x The unit must be within 7 feet of an 110V electrical outlet. A 7'5" cord is included

with the unit.

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