On some aircraft (like the Lycoming IO-540 engines) the induction box covers up the oil pan where the SAFE-HEET would normally be installed. It is permissible for the SAFE-HEET to be installed on the induction box, because the box/plenum is a thick casting that can transfer heat effectively.
No, you will need to use a converter that can supply 3 amps at 120 volts to operate both a SAFE-HEET and 707.
Yes, the 707 is rated at 600 watts. This is enough power to run two units by using a splitter.
SAFE-HEET engine heaters are installed with a two-part adhesive. The engine heater can be installed quickly and easily by using the 707 temperature controller at half power. At temperatures below 70°F the temperature controller must be used to ensure proper adhesive cure. Proper adhesive cure is essential to full service life of the heater.
Twenty hours at a temperature of 70 degrees. If using a temperature controller you can turn the thermostat to about 110 degrees and it will take about seven hours to cure
The amount of adhesive contained in each kit is enough to do one installation and offers better thermal heat transfer than using a larger quantity. The adhesive should be thin, if there is no adhesive 1/8” from the edge of the pad it will not be a problem because our adhesive is totally resistant to solvents or oils. Sealing the edges is not necessary. Using silicone adhesives will allow the heat pad to come loose because silicone is not resistant to solvents or oils. If you feel you need more adhesive, we will send you more at no charge upon request.
No, neither a SAFE-HEET nor Temperature Controller should be plugged into 240 volts. You can use a system with an adapter that reduces the voltage to 110 and can supply at least 3 amps.
Reference the troubleshooting instructions provided with the purchase of a SAFE-HEET. The GFCI will not work unless plugged directly into an outlet. Plug in the GFCI then the temperature controller. The GFCI needs to be the first thing plugged into the circuit. The GFCI needs full voltage to engage. It cannot have an extension cord plugged in the outlet, then the GFCI to the SAFE-HEET. The GFCI does reset itself every time it is unplugged.
Yes, if the temperature is controlled to prevent condensation which can lead to corrosion.
It costs about 3 cents per hour to operate.
The GFCI protects the SAFE-HEET and engine from any electrical fault situations by shutting off power to protect people and the engine. Abuse of the power cord can cause dangerous electrical failures.
This is determined by experimentation on knob settings and several variables such as ambient temperature, wind, size of engine/propeller combination and insulation of engine cowling.
McFarlane’s adhesive is thermally conductive, so it transfers heat effectively while the other brands use a peel and stick tape that tends to fall off. As a result, McFarlane’s has a longer life over the other brands. McFarlane’s adhesive is resistant to solvents/oils but if it ever does fail, the heat pad is not going to jam up anything in the engine compartment, because it is not a solid metal like other brands out there. SAFE-HEET heats the engine oil while other brands heat the cylinder, not the oil. SAFE-HEET is safe and is electrically grounded with a ground wire. The SAFE-HEET pad covers a large surface. McFarlane’s GFCI can be used with any heater, not just SAFE-HEET.
The kit includes the SAFE-HEET and temperature controller. The temperature controller makes installation easier and helps control condensation which leads to corrosion. It is like a dimmer switch that puts you in control of how much power is going to the unit.
