U.P.1 Instructions

Please read all the instructions before starting.
Your valve has been tested and the speed controls have been pre-set. Please do not change any of the settings until you have tried the valve in your model.

Installation
Connect the valve to your servo using a standard quick link. Adjust the servo travel such that the shuttle of the valve travels to its maximum in both directions. Attach the airlines to the valve; it is now ready for speed control set up. Having connected the airlines as required and adjusted the servo travel to give the correct movement to the valve shuttle (.3 inches), charge the system with air and cycle the valve. When the leg has completed its travel, operate the valve to return the leg. If the speed is correct all you have to do is tighten the needle valve locknuts and go fly. However, if the speed is not what you require use the following procedure.

Adjusting the Valve
Slightly slacken the needle valve locknuts. To reduce the speed, turn the needle valve clockwise. To increase the speed, turn the needle valve anti-clockwise. Caution: do not turn the needle valves more than an eighth of a turn at a time without testing the speed. Repeat the adjustments until your desired cycle speed is reached then carefully tighten the locknuts. Please note that if the valve has not been operated for some time it will require more force for the first actuation. This is due to the three ?o? rings sticking and is
nothing to be concerned about.

Safe Operation
When assembling your aircraft ready for flight make sure that the valve position corresponds to the actual position of the retracts. If this precaution is not observed the retract will snap to the position at which the valve is set when the air system is pressurized.

IF YOU HAVE ANY PROBLEMS, PLEASE PHONE AND ASK FOR HELP.
Do not disassemble the valve.

Trouble Shooting
Air is heard to leak from the valve continuously: we have found that most apparent valve leaks are in fact retract cylinder leaks. If the ?o? ring in the retract cylinder leaks it will allow air to find its way via the exhaust side of the cylinder to the valve, and then to atmosphere. If that is the case then it will sound as though the valve is leaking.

To check the valve, disconnect it from all the retract cylinders; connect the two up outlets together and also connect the two down outlets together. Apply air to the valve and actuate it. All that should be heard is a very short hiss each time the valve is moved followed by no air sounds at all. If the valve meets these conditions it does not have a leak. If the valve truly leaks, you have two basic options: either send it back for repair/replacement (phone for shipping instructions), or carefully disassemble the spool from the valve body by removing the snap ring and sliding the spool out. With the spool removed, check for dirt or dust contamination. If there is contamination, wipe of the spool with a lint free cloth, lubricate with Dow Corning #55 grease and re-assemble. If that does not cure the problem, please contact us for help. Assuming that the valve did not, or now does not leak, connect the retracts and cycle them. If air is heard to escape from the valve on a continuous basis, then the retracts are at fault.
