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 electrical 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. Contact CUNO Food Service Authorized Distributor for service.

3. Carefully examine the UV system after installation. It should not be plugged in if there is water on parts not intended to be wet.

4. Do not operate the UV system if it has a damaged cord or plug, if it is malfunctioning or if it is dropped or damaged in any manner.

5. Always disconnect water flow and unplug the UV system before performing cleaning or maintenance activities. Never yank the cord to remove from an outlet; grasp the wall plug and pull to disconnect.

6. Do not use this UV system for other than intended use (potable water applications). The use of attachments not approved, recommended or sold by the manufacturer or distributor may cause an unsafe condition.

7. Intended for indoor use only. Do not install this UV system where it will be exposed to the weather or to temperatures below freezing. Do not store this UV system where it will be exposed to temperatures below freezing unless all water has been drained from it and the water supply has been disconnected.

8. Read and observe all the important notices and warnings on the UV system.

9. If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less amperes or watts than the UV system rating may overheat and create a fire hazard. Care should be taken to arrange the cord so that it will not be damaged, tripped over or pulled.

10. SAVE THESE INSTRUCTIONS.

Water Chemistry

Water quality is extremely important for the optimum performance of the UV system. The following levels are recommended for installation:

• TOTAL IRON count is less than 0.3 ppm (mg/l)

• HYDROGEN SULFIDE count is less than 0.05 ppm (mg/l)

• SUSPENDED SOLIDS count is less than 10 ppm (mg/l)

• MANGANESE count is less than 0.05 ppm (mg/l)

• HARDNESS count is less than 7 gpg (where total hardness is less than 7 gpg, the UV system should operate efficiently provided the quartz sleeve and/or sensor probe is cleaned periodically)

If the water chemistry contains levels in excess of those mentioned above, proper treatment is recommended to correct these water problems prior to the installation of the UV system. Consult a CUNO Food Service Authorized Distributor for pretreatment recommendations.

Before Installing the System

The CUNO Food Service UV system is packaged as follows:

• Stainless Steel Reactor Chamber

• UV Lamp with Quartz Sleeve

• Patented Electronic ICE Ballast

NOTE: A minimum of a 5 micron sediment filter (not included) must precede the UV system. NOTE: For cold water use only. NOTE: For potable water use only.

Installing the UV System

CAUTION:

• The UV system must be connected to a ground fault interruptor.

• The electronic ballast should be mounted either above or beside the reactor chamber. This will prevent moisture caused by condensation from entering the ballast enclosure, a potential for ballast failure and electrical shock hazard.

• The UV system must be installed within 5 ft (1.5 m) of an electrical outlet.

• The electronic ballast must be connected to a grounded receptacle and the lamp connector ground wire connected to the reactor chamber.

• The complete water system, including any pressure or hot water tanks, must be sanitized before the start-up of the UV system to destroy any residual contamination.

Installation

Note: The reactor chamber should be mounted in the vertical position with the lamp connector on top. The water flow

must enter from the bottom port and exit from the top port to ensure optimum operating efficiency. If the chamber cannot be mounted vertically, horizontal mounting should only be done with the ports facing up. Leave enough space to allow for the removal of the UV lamp and/or quartz sleeve (typically leave a space equal to the size of the system itself).

1. Remove the UV system from the shipping carton. For shipping purposes, the UV lamp is packed in a separate cardboard tube. Carefully remove the UV lamp from the tube, being careful to handle by the ends only. Remove the plastic end cover. Do not touch the glass itself.

2. Insert the UV lamp into the quartz sleeve, making sure the connection end is inserted last and centering spring is inside of quartz sleeve. Affix the lamp connector to the UV lamp pins, press-fit into the aluminum gland nut, and replace the plastic end cover.

3. Mount the reactor chamber to the wall with the supplied clamp(s). Mount the electrical ballast to the wall either above or beside the reactor chamber.

4. Various connection methods can be used to connect the water source to the UV system, however union type connectors are recommended. The use of a flow restrictor device is strongly recommended when installing the UV system in order that the manufacturers recommended flow rate is not exceeded. In addition, the use of a bypass assembly is recommended for emergency use of untreated water when the UV system is being serviced. NOTE: When the UV system is returned to service after being on bypass, the complete water system must be sanitized once again to destroy any contamination that may have entered the distribution system while on bypass. DO NOT SOLDER CONNECTIONS WHILE ATTACHED TO THE UV SYSTEM AS THIS COULD DAMAGE THE O-RING SEALS.

5. Prior to connecting to the power source outlet, check all connections to ensure that they are secure, slowly turn on the water supply, and check for leaks. The most likely cause for leaks is from the o-ring seal. In case of a leak, shut off water, drain the cell, remove the retainer nut, wipe the o-ring and threads clean, and reinstall.

6. Once it is determined that there are no leaks, ground the reactor chamber. To do so, attach the green wire coming from the electronic ballast to the grounding lug on the reactor chamber. Remove the green cap nut and slide the eyelet connector onto the screw. Fasten the cap nut to the screw with a 5/16” wrench.

7. Plug the electronic ballast into the power source outlet. Ensure that the ‘POWER-ON LED’ is illuminated. The audible alarm will enter a self-test mode when power is first applied to verify the ballast operation.

NOTE: If the ballast enters alarm condition, power must be disconnected for 30 seconds to allow ballast to reset. NOTE: To clear any air from the lines and to flush any warm water from the system, open any downstream cold water

tap and allow to run for 1-2 minutes. NOTE: As the system requires time to reach its full operating capacity, allow the sterilizer to operate for 3-5 minutes prior to use.

Operating and Maintenance Instructions

• Always disconnect power before performing any work on the UV system.

• Regularly inspect the UV system to ensure that the UV light is still glowing and that its LED indicator is still glowing green.

• Replace the UV lamp annually to ensure a high bacteria and virus kill rate.

• Always drain the UV cell if leaving the system in an area subject to freezing temperatures.

UV Lamp Replacement

1. Disconnect the power.

2. There is no need to disconnect the UV system from the water supply or to drain the water from the reactor chamber, nor do you need to remove the reactor chamber from the UV system. Lamp replacement is a quick and simple procedure requiring only a slotted screwdriver to perform the job. After 9,000 hours of continuous operation (approximately one year), the UV lamp should be replaced.

3. Remove plastic end cover on the UV system. Remove lamp connector from gland nut and carefully slide the UV lamp slightly out of chamber. Remove the lamp connector from lamp and fully remove lamp (be extremely careful when handling UV lamp as they are extremely fragile).

4. To install the new lamp, carefully remove from protective tube being careful to handle by the ends only. Do not touch the glass itself. Slide UV lamp into the reactor chamber. Affix lamp connector to the UV lamp, slide lamp fully into cell, press fit lamp connector into aluminum gland nut and replace plastic end cover.

5. Reconnect the power source. Verify “POWER-ON” LED is illuminated and ballast audible start-up sequence operates.

Quartz Sleeve Replacement and/or Cleaning

1. Mineral deposits and sediment may accumulate on the quartz sleeve decreasing UV output. Good maintenance of filtration equipment will reduce the accumulation of residues. If necessary, remove the quartz sleeve after a few months and clean with a commercially available scale remover and lint free cloth. Repeat the process as often as necessary to keep the quartz sleeve clean.

2. If the water contains any hardness minerals (calcium or magnesium), iron or manganese, the quartz sleeve will require periodic cleaning. To remove the quartz sleeve, first remove the UV lamp as outlined in Step 1, 2 & 3 of the UV lamp replacement instructions above and follow these steps:

A. Shut off water supply and drain all lines. B. Remove the lower connection on the reactor and drain the UV chamber (use a small bucket under the unit to

prevent a spill). C. Remove aluminum gland nut from chamber. Do not allow quartz sleeve to fall. D. Carefully remove o-rings from the quartz sleeve. As the o-ring may tend to adhere to the quartz sleeve, it is

recommended to replace the o-rings annually. E. Clean the quartz sleeve with a lint free cloth and commercially available scale remover and then rinse. F. Reassemble the quartz sleeve in the UV chamber allowing the sleeve to protrude an equal distance from both

ends of the UV chamber. G. Lubricate the o-rings with food grade lubricant and slide onto each end of the quartz sleeve and reassemble

the gland nuts (hand tight is sufficient). H. Retighten all the connections, turn on the water and check for leaks. I. Reinstall the UV lamp and lamp connector as per prior instructions. J. Plug in ballast and verify the “POWER-ON” LED is illuminated and ballast power-up sequence operates.

NOTE: If the system is put on a temporary bypass or if it becomes contaminated after the sterilizer, it will be necessary to sanitize the downstream lines before resuming the use of the water.
