4.3 Electrical Requirements

The Quest 150 Dual plugs into a common grounded outlet on a 110-120 VAC 15-Amp circuit. While operating, it draws 

11.0 amps @ 80°F, 60% RH and 10 amps @ 75°F, 50% RH. Use of a ground fault circuit interrupter (GFCI) protected 

circuit is recommended. The unit should not be used in areas prone to flooding. 

 CAUTION! For proper drainage, the unit must be mounted so the drain outlet is at least 4” 

above the floor drain, and must be fully supported under the base. 
4.4 Installing Feet 

Included with your Quest 150 Dual are four leveling feet. It is important to level the unit for 

proper draining.

Installing Leveling Feet

See Figure 2 for installing leveling feet.
1.  Lay down a protective pad (pillow, blanket, etc.).
2.   Carefully turn unit onto side opposite drain port.

3.   Align leveling foot shaft with one of the four threaded hole locations as shown in Figure 2.
4.  Screw each leveling foot in ten revolutions.
5.  Carefully bring unit to upright position.
6.   Level unit for proper water drainage.
7.  Wait 10 minutes before operating.

 CAUTION! Note: Operating the unit immediately after bringing it to an upright position can 

possibly damage the compressor. A short amount of time is needed (10 minutes) to allow the oil to 

return to it’s reservoir for lubrication.
