6.0 Start-Up - Once you have completed all steps above, including (IMPORTANT) verification that the unit has no

leaks anywhere, including a possible broken quartz tube damaged during transit, you are ready to start your unit up.

6.1 Start Up Circulation Pump - Once the pump is on, be sure to drain all air from your system through the

air relief valve on the filter if so equipped.

6.2 Check EP Unit For Leaks - Make one final check for leaks in your piping, accessories, and under the

electrical enclosure bonnet. If any water leakage under the EP unit’s electrical enclosure bonnet is suspected

(water dripping from under side of bonnet), disconnect the EP unit immediately, remove the bonnet (see 7.3)

and verify that there is either a) no leakage or b) stop the leakage of the quartz tube gasket. If quartz tube

leakage is encountered, follow the instructions in Sections 7.4 through 7.6 and 8.1 through 8.5 to remedy the

situation before applying electrical power to your EP unit.

6.3 Swimming Pool Chemical Balance - Check the chemical balance of your swimming pool and adjust

the chemical balance as per your pool chemical suppliers instructions. Remember, the EP unit reduces

chemicals, but does not eliminate the need for proper pool chemical balance.

7.0 Quartz Tube Maintenance - The EP unit requires very little maintenance during the year. The UV bulb in the EP

unit is placed inside a quartz tube to protect the bulb from the water in the EP unit’s wet chamber. This quartz tube can

have its ability to transmit the UV rays from the bulb through the quartz tube diminished if the quartz tube becomes

dirty or laden with deposits. The quartz tube should be removed from the wet chamber every six (6) months and

inspected to make sure it is clean and that deposits are not attached to the quartz tube. To remove the quartz tube,

you should follow the steps shown below.

7.1 Disconnect Power - Unplug the EP unit from its power receptacle.

7.2 Stop Your Circulation Pump - You must shut off the circulation pump so that no water is flowing into the

EP unit. Once the pump is shut off, verify on the pressure gauge that the pressure inside the EP unit is ZERO.

If any pressure is indicated on the pressure gauge, do not go to the next step until the pressure gauge shows

ZERO. If you show any pressure on the pressure gauge, but feel that there is no pressure present inside the

EP unit, simply unscrew the top union nut on the EP unit. This will relieve any pressure. With the union

partially unscrewed, the pressure gauge should show ZERO. If it does not, replace the pressure gauge (Part

# 84-82234) immediately. When you are absolutely sure that there remains no pressure inside the EP wet

chamber, you can proceed to the next step.

7.3 Remove The Plastic Electrical Enclosure Bonnet - NEVER REMOVE THE ELECTRICAL ENCLOSURE

BONNET WITHOUT FIRST UNPLUGGING THE EP UNIT FROM ITS POWER SOURCE – DO NOT OPERATE

THE EP UNIT WITH THE BONNET REMOVED - The electrical enclosure bonnet is removed by unscrewing

the four mounting screws that hold the bonnet to the EP unit.

7.4 Remove The UV Bulb - First make sure the bulb is cool before handling. Do not handle a hot UV bulb to

avoid burning your skin while handling the bulb to be removed. Unplug the UV bulb by grasping the white bulb

connector attached to the ballast wires. Slowly pull the UV bulb out of the quartz tube by grasping the bulb

on the white ceramic prong end. DO NOT TOUCH THE UV BULB GLASS WITH YOUR BARE HANDS ! Use

a soft clean cotton cloth or clean cotton gloves to handle the UV bulb. Skin oils on your hands can attach to

the bulb and can cause hot spots on the bulb which can shorten the bulb life. Carefully place the removed

bulb in a safe location while cleaning the quartz tube. The quartz tube is now ready to be removed from the EP

unit for cleaning.

7.5 Remove The Acorn Nut - Using a crescent wrench or 1-11/16” socket, remove the black plastic acorn

nut (Part # 86-02411) holding the quartz tube into the stainless steel mounting gland. Note that there is a

rubber sealing gasket (Part # 44-02018) around the quartz tube (or inside the acorn nut) that seals the quartz

tube to the mounting gland. Set the gasket aside to reseal the quartz tube when you re-install the quartz tube

after cleaning.
