Do i need to remove the jumper before i install this unit?

what jumper? Look at the wiring diagrams of your thermostat. The power to the thermostat is only to be used if your furnace/thermostat connection doesn't use a 24vac power source. My thermostat needed the extra and I was able to to simply determine that the two wires from the power supply should be on The 3M-50 can be externally powered with a power source rated from 12V to 24V, AC or DC, at connect to the C and RH terminals (no polarity). Look at your thermostat wiring diagram to determine the correct connections. My system is very happy with this arrangement, but be careful not to mis-wire your connections. If you cannot find the correct placement, I recommend calling to your thermostat or furnace manufacturer to be sure of the placement, most 'high-efficiency' units are very computer oriented and please do not risk damage to the control unit on your furnace by mis-wiring.

mine did come with jumpers, however I had to power down and then repower it up to get it to work, one of the relays was stuck.

No, the solenoid is separate and mounted beneath the battery on the firewall. Do not buy a starter with the solenoid attached.

Nope. The sensors and switches are all built in. Very easy to install the unit. Pick up some weather calking before installing unit. Takes 10 minutes to install.

It is in the instructions. It depends upon where you put the wiring instead of having dip switches to set. You will have to do some minor rewiring which is detailed very well in the instructions.

No. The sensors are part of the safety circuit. Could they be jumped out, yes if you knew what the resistance was telling the opener everything is ok.

no I did not use any jumpers .I just took it the hard drive out of the box then I took the screws off of the old one and put them one the new one and used the sata cord that was already in the computer and hooked it all up and it worked . I would check the Bios to see if it will detect the drive.

The jumper enables you to isolate the relay control circuit from the coil (The relay has optical isolation when the jumper is removed). If you remove the jumper you'll need to provide power to the coil separately. This is useful if the device that is controlling the relay can't provide enough current (or voltage) to drive the coils. I have a short video of the relay in operation in my review (http://www.amazon.com/gp/review/R2AZD0UTXMKUD1/ref=cm_cr_pr_rvw_ttl?ie=UTF8&ASIN=B0057OC6D8) - Unfortunately I don't show the jumper in use though.

Sorry but, I just went ahead and connected the neutral since it was there, I don't know if it's required.

No jumpers. However you could wrap a long wire around several input screw posts allowing different output screws to share the same source

I agree with you. I also did not find it very clear. My advice is to pay close attention to what to what is written not the diagram. It is very easy to install incorrectly otherwise. Also before you remove faulty sensor - not how the wires are attached and label them before removing. That way you can install replacement without instructions. Finally - new time delay switch is touchy. I would set it to middle position. Good luck.

No, it didn't for me, just the unit itself. FYI: I was replacing an existing unit of the same make & model, so already had all wiring/tubing in place.

No you have to remove handle from shaft during install. Yes all wiring and switch are included.

Installation instruction not included, please be sure you know how to install before bid

As far as I know, it cannot be removed. Nothing can be disasbled, at least for me nothing could. When I brought it over to my sisters & moms for babysitting, I had to put the entire thing aasembledin the back of my SUV. That is the only thing that I did not like about the jumperoo other wise I think its the best one by far. I think its for safety reasons.

No. The unit will work without any of the attachments installed. I use it that way all the time.
