Page 3: Description Of Equipment
Flow rate must not exceed rated capacity of the unit. DESCRIPTION OF EQUIPMENT: The PT series has an unique design with an ultraviolet germicidal lamp housed within a single quartz sleeve surrounded by a stainless steel pressure chamber. The chamber is fabricated out of 304 Stainless Steel. -
Page 4: Installation
U.V. disinfection units must always be properly grounded. INSTALLATION: The PT series are always placed after the pressure tank and any other type of treatment devices (i.e. softeners, filters). These units are normally installed in a vertical position in an enclosed area with good ventilation. Allow clearance of at least the unit’s length at one end for quartz sleeve and bulb replacement. -

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. - Page 7 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.

Page 9: Quartz Sleeve
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. - Page 10 ELECTRICAL: The PT series are furnished with 6' line cord that will plug into a 110V outlet. Electrical receptacles must be properly grounded for safe operation. Improper grounding will void any warranty. When possible use a separate breaker to minimize voltage fluctuations and avoid accidental shut off.

Page 11: Disinfection Procedure
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. - Page 12 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.
- Page 13 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.
- Page 14 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.
