The Harris Smoke Pump can be setup two different ways to operate on your Radio System.
*Setup #1 If you would like your pump to operate from an auxiliary channel like Retract or Flap and turn on & off from a switch. Plug in your pump to a switch activated channel for example (retract/landing gear). Your pump will then turn on & off by operating the toggle switch for that channel. You can change the flow rate of the pump by accessing the ATV or End Point Adjustment from your transmitter. Too much fluid flow will cool the mufflers, reducing smoke clouds and wastes smoke fluid. Properly adjust fluid flow to make whiter clouds of smoke.
*Setup #2 Mixing throttle with your smoke channel. This method is used to activate the smoke system and when activated, the smoke system turns on when the throttle stick is advanced beyond a set point. Fluid flow will increase as throttle is advanced and decrease as throttle is lowered.
*Open a Mixing Program (1) Set throttle as master channel. (2) Set an auxiliary channel as a slave channel- for example retract/landing gear- (3) Increase the travel value of switch position 0 to maximum travel. (4) Leave the travel value of the switch position 1 at 0%. This will enable you to turn the pump on and off from your auxiliary switch. You can control when the pump comes on by changing the value of the offset. A low offset value will cause the pump to come on just off idle. You can increase the offset value to have the pump turn on at any stick position. This setup will increase fluid flow when throttle is advanced and reduced fluid flow when throttle is lowered so that the pump will provide a regulated amount of fluid according to throttle position. (5) If you need to adjust the maximum fluid flow you can do so by decreasing your ATV/End point adjustment on your slave channel.
Installation
The Harris Smoke Pump is EASY to install.
Choose the proper size smoke fluid tank for your airplane. Smoke fluid tanks should be assembled with 3 lines: tygon tubing is used to plum the tank & lines, 1 line for klunk, 1 line for vent, and 1 line for filling the tank. The fill line should be bent to the bottom side of the tank. This is so you can remove all the smoke fluid from your tank at the end of your flying day if you don’t pump the system dry during flight. Install your tank on the center of gravity so your balance does not change with fluid capacity. Mount the pump behind the smoke tank. This ensures that in a high gravity maneuver the fluid will be forced to the pump and keep it primed. Mount the pump with fittings in the vertical position. Any fluid left in the line will keep the pump head properly lubed. Cut a piece of foam rubber to mount the pump on. Velcro the foam rubber to the pump then Velcro the other side down of the foam rubber to the airplane. Secure the pump with 2 zip ties to the airframe. Tighten the zip ties down but allow the pump to articulate a little.
*When you are looking at the pump head the intake (klunk) line goes to the left hand fitting and the exit line goes to the right hand fitting. Install either a klunk filter or inline filter on the klunk line to filter the fluid before it enters the pump head. The exit line goes to the firewall area. A check valve needs to be installed on the exit line close to the muffler. The check valve keeps fluid right behind the muffler so the pump will not loose prime and you get instant smoke when you turn the system on. The exit side of the check valve will attach to the smoke muffler fitting with a black piece of Neoprene tubing. This is very important; Neoprene will not heat up and fall off. Place a small piece of heat shrink over the neoprene & muffler fitting so every time the fitting gets hot the neoprene connection will keep tight and prevent a line coming off.
The Pump can run on 4.8 volts up to a 2-cell LiPo 8.4 volts max. a 480- 800mAh pack. It is not necessary to run any type of larger battery. 6 Volts regulated is recommended for best performance. You can Velcro the small battery pack close to the pump. A small 2 pin connector can be used to provide plug in power to the unit. A switch can be added to provide on & off power to the pump also. If you choose to have a switch. For simplicity we plug the battery directly into the pump and unplug it at the end of the flying day. The pump will not operate until the Tx and Rx are turned on. When plugged in, the pump will give an audio beep every couple of minutes to let you know it has power.
WARRANTY INFO
*WARRANTY PERIOD 90 DAYS from the date originally purchased.
*Only use smoke fluid that is specifically used for Radio Controlled such as Bennett’s or Superdry.
*Do not modify, adjust or take apart your pump, this will void all warranty terms.
*Do not plug power in backwards to pump control unit, this will void warranty.
*If you need to remove Tygon tubing from the pump fittings, do not pull them off without slicing the Tygon tubing first with a sharp knife. Too much force will break the fittings. Operator mistakes will not be covered under warranty.
*Crash damage is not cover under warranty.

The Competition Pump plugs directly into your receiver for power. It is necessary to run either a 5 cell Ni-Cd/ Nimh pack or a lithium type battery regulated down to 6 volts. This pump will work on a 4 cell ni-cd/ nimh battery. 2000mah or higher capacity is recommended. The pump is also compatible with 2.4 systems running direct off a 2 cell Lipo with no regulator. In these configuration the pump only draws between
300-600mah. For instance if you ran the pump for 1 hour, it would only draw 300-600mah total. This is a very small power consumption. If you smoke your airplane 5 mins. total per flight, you might use 60-80mah.
