Air Conditioners

Situation: A 220 air conditioner in a New York co-op with no 220 volt outlet to power it.

Solution: Donnie used a Quick 220 Voltage Converter to create a 220 volt outlet for the air conditioner. We thank him for sharing his experience.

“When I moved into my apartment I found it had a through-the-wall air conditioner sleeve. I ignored it and installed my window air conditioner. When that old AC died about 3 years ago, I was told by the co-op board that the rules had changed and I had to use the sleeve. I guess I should pay more attention to coop board announcements. My problem was that next to the sleeve was a 110V outlet but every AC that fit the sleeve required 220V.

After being quoted over $1000 to run 220V to the sleeve I was desperate to find another solution. Luckily, I found the Quick 220 Power Converter. All it took was the 110V outlet near the sleeve and an extension cord from another 110V outlet on a different circuit. Instantly, I had two 220V outlets. And at $160.00 I was very happy with the price. They also throw in an outlet tester because both 110V outlets must be wired correctly (not something you can assume in an old apartment) for the Quick 220 to work.”

Clarifications to CoolTools Discussion

  1. 1. Voltages. In most commercial settings and many apartment buildings, the electric utility supplies three phase electric power and configures it to give about 120 and 208 volts in these buildings. Single residences and smaller apartment buildings are usually supplied with a single phase, which gives about 120 and 240 volts. As detailed in the specifications, Quick 220 Power Supplies will give about 208 or 240 volts, depending upon whether the electrical system has 3 phases or a single phase. Air conditioners are usually designed to accommodate both the 208 and 240 volt electrical systems. To be sure, check the rating label on the air conditioner. If you have a question, please call us.
  2. 2. Safety and Certification. The Quick 220 Power Supplies meet the fire and safety standards of UL (Underwriters Laboratories), CSA (Canadian Standards Association), and OSHA (United States Department of Labor, Occupational Safety and Health Administration.)
    1. A. UL and CSA publish product safety and testing standards for use in the United States and Canada. Quick 220 Power Supplies conform to UL Standard for Safety Power Units (UL1012) and to CSA Standard for General Use Power Supplies (CAN/CSA C22.2 No. 107.1.)
    2. B. Qualification of testing laboratories in the US is under OSHA, which recognizes about 15 labs to test products. Intertek Testing Services, an OSHA recognized lab, tested and certified the Quick 220 Power Supplies to both UL and CSA standards. Additionally, Quick 220 Systems is inspected quarterly by Intertek to assure continuing compliance with the standards. Quick 220 Power Supplies are listed In the Directory of Intertek Certified Products and bear the Intertek “Listed” Certification Mark for both the US and Canada.
    3. C. UL, CSA, OSHA, and the Nationally Recognized Testing Laboratories concern themselves with the safety of products that are brought into the home or business. The NEC (National Electrical Code) addresses the permanent wiring of buildings and other facilities. In general, if it is in the walls or a permanent part of the facility, NEC defines how to do it safely. If you can plug it in, then UL, CSA, OSHA and the testing laboratories address product safety.
  3. 3. Quick 220 Functions. Some of the contributors to the CoolTools discussion were uncertain about the operation of the Quick 220 Power Supply. Here is a summary.
    1. A double pole circuit breaker is mounted in the side of the case, recessed to prevent accidental on/off switching. It is either a 15 or 20 ampere breaker, depending on the model Quick 220 Power Supply chosen. The breaker protects the item connected, the Quick 220 Power Supply, and the building wiring. Incidentally, the branch circuit breakers in the building perform the same functions at a different level. When extension cords are used, the user should use electrical cords of appropriate gauge for the ampere load. This is detailed in the instructions.
    2. The Quick 220 Power Supply has internal safety interlocks that function as follows:
      1. No power is available at the 240 volt outlet until BOTH 120 volt power cords are plugged into 120 volt outlets that are electrically out of phase. Should one of the 120 volt power cords lose power or become disconnected, ALL power is immediately cut off from 240 volt outlet. This protects the user and the equipment from the effects of the equipment receiving the wrong voltage by mistake or circumstance.
      2. Until a 120 volt power cord is connected to a 120 volt electrical source, it is electrically isolated from the electrical circuits of the Quick 220 Power Supply. This protects the user from accidental shock through the exposed plug contacts.
      3. Should one of the 120 volt supply outlets be wired incorrectly and have the hot and neutral lines reversed, the Quick 220 Power Supply prevents any electricity from being connected to the 240 volt outlet. This is to prevent damage to the air conditioner and any other consequences of low voltage.
    3. A Quick 220 Power Supply will trip ground fault circuit interrupters (GFCI or GFI) which are typically found in wet areas, for example, kitchens and bathrooms. One should select electrical circuits in areas of the building that do not have GFCI’s. An outlet tester is supplied with every Quick 220 system that will quickly identify GFCI controlled outlets.

Quick 220 Recommendations

For 208-240 volt air conditioners having a 15 ampere, straight blade plug, NEMA 5-15, the Quick 220 Model A220-15D is the system of choice.

For 208-240 volt air conditioners having a 20 ampere, straight blade plug, NEMA 6-20, choose one of the packages containing the Quick 220 Model A220-20D. The 120 volt supply circuits should be rated at 20 amperes.

Option 1: P-107 (includes Model A220-20D plus two 20 ampere, 120 volt extension cords)
Option 2: P-101 (includes Model A220-20D plus one 20 ampere, 120 volt extension cord)
Option 3: P-106 (includes Model A220-20D)
