2. INSTALLATION INSTRUCTIONS

Before Beginning Installation

Water Conditions - Pre-treatment Parameters

Note this section is designed to ensure the optimal performance of your

Upstream system. Please review the following pre-treatment parameters prior to

installation.

If any specifications are of concern or unclear please contact your water

treatment dealer or specialist. Note some of the information below is technical in

nature and you may want to contact your water treatment specialist to review the

parameters.

IMPORTANT - Should any of the following water parameters exceed the

recommended limits; the system will not be serviceable under warranty.

Water Parameters for Treating Drinking Water:

The minimum water requirements for operating the Upstream system are:

 UV Transmittance (UVT) – see Product Specification Table. It is

recommended for the water to be tested for UV transmittance in any

applications using cisterns, surface water or ground water under the

influence of surface water.

 Total Dissolved solids (TDS) - must be less than or equal to 1000

mg/L (mg/L=ppm)

 Level of turbidity - or cloudiness - of less than or equal to 1 NTU

(nephelometric turbidity unit). A 5 micron sediment filter is

recommended before the unit to reduce turbidity (the presence of a filter

will also simplify disinfection of plumbing – see Disinfecting the

Plumbing). For surface waters, a dual gradient pre-filter (75x25 or 50x5)

is recommended.

 For temperature, pressure range, and other specifications, please see

Product Specification Table.

The 1” Upstream units include a flow regulating device to limit the flow rate.

Warning: Removal of this device may allow the water flow to exceed the

validated performance of the system which therefore may not provide the

necessary UV dose to inactivate all pathogens.

Safety Information

GROUNDING

This UV unit must be grounded. In the event of a malfunction or breakdown,

grounding will reduce the risk of electric shock by providing a path of least

resistance for electric current. This unit is equipped with a cord having an

appliance-grounding conductor and a grounding plug. The plug must be plugged

into an appropriate outlet that is installed and grounded in accordance with all

local codes and ordinances. The piping connected to the UV unit must also be

properly grounded. Install a grounding lug or strap as required.
