Zurn Fusion Lock T Installation and Operating Instructions
Power input requirements: 115 Volts AC, 7.5 amps, 60 Hz. The unit will be ready to operate after turning on and short 'self-test' is completed.

Making the Zurn Fusion Lock T Joint Connection
A Fusion Lock joint connection is simply and quickly accomplished by doing the following .
1. Cut pipe square and de-burr ends.
2. Insert Fusion Lock T seal into joint and rotate leads to desired easy access position. Push leads inward and hand tighten locking nut onto fitting. Then push leads outward to make sufficient room for pipe. Remember: There is no need for an additional band clamp.
3. Insert pipe into joint assembly completely and finish tightening the nut 1/4 to 1/2 additional turn using spanner wrench.
4. Turn on the welder box, it is protected by a thermal circuit breaker switch. There is no need to select the joint size when using the Zurn unit; you can fuse multiple joints of the same or different size at the same time. (Note: To do this, joints must be connected in-series.)
5. Connect the fusion unit clips to the seal leads and press start on either the control box or the remote control device. Note: After starting, the unit will per-form a brief system check to ensure the leads are connected properly, sufficient power is evident, and the maximum number of simultaneous joints has not been exceeded.
6. Wait while joint is fusing - the unit display will count down remaining weld time. The Zurn fusion unit will automatically compensate, incrementally, for job site temperature (hot or cold) conditions to reach ideal fusing temperature.
7. Upon completion, an alarm will sound. Remove the leads and move on to the next joint. Remember: There is no need to go back and further tighten the nuts.

Features of the Fusion Lock T Machine
. Simple operation - fully automatic control and timing.
. Multiple joints may be connected in-series up to the specified maximum. Joints of different sizes may also be fused simultaneously. Any combination of pipe sizes can be welded in series. Versatile and fast! Saves time and money.
. All joints use the same current (12 amps).
. Even heat is applied to all sizes of joints, and any number of joints up to stipulated maximum ensures joint integrity and reduces errors.
. Automatic compensation for ambient temperature.
. SAFETY! Lighter weight, more efficient toroid transformer provides line isolation.
. Transformer and Solid State Relay run cool - no "resting" is necessary - saves installation time and money.
. Unit is protected by a 10 amp thermal circuit breaker - equipment protection!
. Power cord contains 12 amp fuse to protect unit if wired to 230 VAC instead of 115 VAC.
. Bright color vacuum florescent display - easy to read!
. Automatic joint integrity detection before starting - saves time and money.
. If welding is briefly interrupted during fusing, the cycle can be restarted and the, unit will compensate for time interrupted to complete the joint.
. If joint is broken for a long period of time during welding, the fusion will be auto-matically terminated and an alarm will sound.
. Operator can stop welding if desired.
. Remote control unit with indicators, on a 28-foot long cord, makes installation easy.
. Electronics are shock mounted and fully contained in a UL listed box - protection!
. UL listed metal box is used to reduce electromagnetic interference, both radiated and induced.
. Reinforced power cords and link cables (jumper wires) - durable!

Caution
Although we have added shock mounts to the electronics and enclosed the components in a UL listed box, the fusion control unit is a sophisticated electronic device that should be handled with care. Do not open device! The unit contains no field serviceable parts. If damaged, please return to Zurn Industries factory for repair.
Do not disturb the joint for 5 minutes after the fusing cycle. Joint should cool for 1/2 hour prior to testing.
Do not test with air. Test only with water.
After testing, if a leak is detected completely drain the system and re-fuse the joint per the above instructions.

Warning
Because of Zurn's unique patent pending system, only Zurn sealing components (nuts and seals) are compatible with our fittings. Only the Zurn fusion unit will provide proper welding of Fusion Lock T joints, i.e. do not use other manufacturer's machines - you must use the Zurn Fusion Lock T machine during installation.
Zurn fittings and pipe conform to the highest industry quality standards and meet all applicable specifications and tolerances. Zurn Industries can only guarantee that Zurn parts are manufactured to the above standards and strongly recommends that you do not mix parts with other manufacturer's products. 
The Zurn combination fitting for both mechanical and fusion joining methods is a patent pending system that offers superior performance.
