PurTest PT Series U.V. Disinfection INSTALLATION & OPERATION MANUAL This manual covers installation, operation and maintenance requirements for PurTest U.V. Light Disinfection Systems. Model - PT-8, PT-12, PT-20 (During normal operation, the Green LED will flash every 5 - 10 seconds.) It is important that those responsible for the installation of this equipment, as well as the owner / operator, read this manual and carefully follow the instructions and guidelines.
SAFETY INSTRUCTIONS WARNING - to guard against injury, basic safety precautions should be observed, including the following: 1. READ AND FOLLOW ALL SAFETY INSTRUCTIONS. 2. DANGER - To avoid possible electric shock, special care should be taken since water is present near electrical equipment. Unless a situation is encountered that is explicitly addressed by the provided maintenance and troubleshooting sections, do not attempt repairs yourself, refer to an authorized service facility. 3.
FUNCTION: The function of this ultraviolet disinfection unit is to provide in excess of 99% reduction of all water borne pathogenic (disease causing) bacteria. Model PT series have a number code designation correspondent to the maximum gpm (gallons per minute) flow rate of the unit. I.E.- PT-8 has a maximum flow capacity of 8 gpm. Applications: Ultraviolet Germicidal Disinfection PurTest Ultraviolet Disinfection Units are designed to destroy micro-organisms in water supplies.
GENERAL CONSIDERATIONS FOR ALL DISINFECTION UNITS: 1. When installing the equipment, it is necessary that the unit be isolated from vibration, heavy equipment, and poorly connected piping. 2. Incoming water temperature to the unit should not exceed 35° minimum to110° maximum degrees Fahrenheit. 3. The operating pressure should not exceed 100 psi. 4. Before putting the unit into final operation follow sanitation procedures as outlined in this manual for proper disinfection.
STEP BY STEP INSTALLATION: 1. Turn off the water before cutting into the water line. 2. Assess the installation (i.e. type of pipe, size of lines, etc.) and obtain necessary plumbing fittings for installation. Inlets and outlets on 8, 12 & 20 gpm units are 3/4" MNPT. Use Teflon tape on all threaded connections and avoid over tightening. Note: The flow control is a press in type.

OPERATING INSTRUCTIONS Your UV System is equipped with the PT-280CB UV Lamp Detector and Timer circuit board which is designed to provide a continuous monitoring system of the UV lamp operational status. This solid state electronic circuit board provides the latest in UV lamp monitoring technology. UV LAMP / CONTROL BOX START UP PROCEDURE - (4 Step Process) 1. Make sure the UV lamp is inserted per instructions into the quartz sleeve and UV chamber. Then plug the UV lamp into the lamp connector. 2.
To Find out how many Months are left on the Lamp Timer - Push the reset button for 1-2 seconds then release. After an initial sound there will be a pause followed by beeping and a flashing LED. The number of beeps corresponds to the number of months left on the lamp life. To Reset 1 Year Lamp Timer – WHEN REPLACING THE UV LAMP. Unplug the control box from the wall outlet. Unplug the UV lamp from the Lamp connector. Replace with a new UV Lamp.
QUARTZ SLEEVE: Installation of the Quartz Sleeve: Always handle quartz sleeves carefully to prevent breaking or chipping. The quartz sleeves are to be clean and free of fingerprints before installing. Remove the compression nut. Install the quartz sleeve (domed end first) into the stainless steel housing, through the threaded nipple. The quartz sleeve will go to the bottom of the chamber and through a quartz receiver located within the bottom of the UV chamber.
U.V. LAMPS: INSTALLATION OF THE ULTRAVIOLET LAMPS: **DO NOT PUT POWER ON AT THIS TIME!** CAUTION: Never look directly at a operating U.V. lamp operate a U.V. lamp outside the disinfection chamber. Make sure unit is unplugged when installing or servicing ultraviolet lamp. Remove any paper tabs on the U.V. lamp and avoid allowing fingerprints and other debris to deposit. Carefully place the bulb inside the quartz sleeve leaving enough space to connect the socket connector to the lamp pins.
SANITATION PROCEDURE FOR INSTALLATION AND BULB REPLACEMENT: HOW TO DISINFECT A WATER SYSTEM: Every new well, or existing water supply system that has been disrupted for service or repair, should be disinfected before it is returned to use. Water in the well and storage tank should be treated with a strong chlorine solution to destroy disease organisms. All pipelines and fixtures in the distribution system should be rinsed and flushed with chlorinated water. Upon installation of a U.V.
LARGE DIAMETER WELLS: Dug or bored wells should be disinfected in the same way as a drilled one. Lower the water level as much as possible, remove the sand, silt and debris, and then treat with the chlorine solution. Mix thoroughly by circulating the water back into the well and use the hose to rinse the interior lining of the well. Do not try to disinfect an unprotected, unlined well because new seepage or surface contamination will flow into the water about as fast as you can disinfect it.
REMEMBER - To make your water supply safe: - Locate your well properly. - Protect it from surface contamination. - Test water periodically for coliform bacteria. (Home-yearly, Farm-2X yearly) - Chlorinate, or filter and disinfect the water if necessary. When installing an ultraviolet disinfection system, a prefilter with sump may serve as a source to sanitize the water lines only. For whole system disinfection follow procedure as outlined above.
DRILLED WELLS: 1. Remove the cap or seal from the casing and measure the depth of the water in the well, then refer to Table 1 to determine how many chlorine pellets should be used. In some instances removing the seal to measure the water can be a difficult task, and it is easier to estimate well and water depth from well log or other records. 2. Remove well cap and determine if there is an unobstructed path from the top of the well to the water level.
TROUBLESHOOTING GUIDE PROBLEM CAUSE U.V. lamp will not light Check input voltage if below or above 120 volts CORRECTION Install a voltage regulator Line cord disconnected Check, replace or outlet defective Defective U.V.

SUGGESTED PROCEDURE FOR OBTAINING STERILE WATER SAMPLES: Prior to taking the water sample, be sure to have on hand an adequate supply of sterile bottles. These sterile bottles should be obtained from a reputable laboratory and should have been autoclaved and contained within a plastic outer wrapping. 1. Prior to taking the sample, it is imperative that the sample cock, faucets, etc. be opened at full force for a complete three and one half minutes. 2.
