Hallett 13 & 30 Instruction Manual - Wastewater & Reuse

2. INSTALLATION INSTRUCTIONS

Before Beginning Installation

Water Conditions - Pre-treatment Parameters

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

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

installation.

If any specifications are of concern or unclear please contact your water 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 preceding water parameters exceed the

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

 UV Transmittance – The Ultraviolet Transmittance (UVT) impacts the

amount of treatment since UV light is absorbed rather than being

available for disinfection. The minimum UVT level is indicated in the

proposal document prepared by UV Pure. This value will also be

indicated on a label on the front of the unit, on the inside of the unit, and

on the outside of the shipping carton.

 Total Suspended Solids (TSS) - The amount of suspended solids

affect treatment by blocking UV light. The maximum TSS level is

indicated in the proposal document prepared by UV Pure.

 Biological Oxygen Demand (BOD) - The maximum BOD level is

indicated in the proposal document prepared by UV Pure

Water Capacity:

The water capacity or peak flow, of the Hallett unit will depend on various

parameters such as UVT, TSS, BOD and level of UV dose required. The peak

flow of unit will be indicated in the proposal document prepared by UV Pure. This

value will also be indicated on a label on the front of the unit, on the inside of the

unit, and on the outside of the shipping carton.

Hallett 13

The water treatment range for the Hallett 13 is 0–50 liters per minute (or 0–13.3

U.S. gallons per minute), with a working pressure of 0–690 kPa (or 0–100 psig).

Hallett 30

The water treatment range for the Hallett 30 is 0–113 liters per minute (or 0–30

U.S. gallons per minute), with a working pressure of 0–690 kPa (or 0–100 psig).

The Hallett units used for wastewater or reuse do not include a flow regulating

device that will limit the flow rate. The flow through the units must be

controlled by the customer.

Temperature Requirements:

Where the unit is installed, the ambient temperature should be between 7–38°C

(45–100°F). If the temperature drops below freezing, drain the unit completely to
