110 volt Transformer
Transformer used in some brands and models, such as: S2, B, B2, E2, QE2, S1, S4, C110, C95, M19, M32, M34, M72, M45. Click here to print a Wiring Diagram to use while installing - ALSO view diagrams from part #242.

110 volt Transformer (large)
Transformer used in some brands and models, such as: SV, SVT, S3, S5, C210, G23. Can also be used for smaller models. BUT NOTE this transformer must be used now with the only replacement relay we sell for all our vacuums. The #242 Relay must be used with the #232 Transformer. To wire correctly see the diagrams in #242 relay and note that you need to choose either the white or red or orange wire (white is for 110-120 volt units, Red is for 208 volt, and Orange is for 240 volt - these instructions are on a sticker on the top of the transformer).

28 amp Relay (replaces relays, requires large transformer)
This relay replaces the smaller ones (#240 and #241) previously sold. It ONLY WORKS WITH LARGE TRANSFORMERS (PART #232 if 110-120 volt or #231L if 220-240 volt) which are typically are not in machines under 20 amps - regardless of what you read elsewhere on this website, this relay requires the larger transformer. You can replace your transformer. The 242 relay works with all kinds of 110 to 240 volt motors, and all minibreakers. It works with an electrical set-up similar to the ones in the following photographed diagrams. Click and print a diagram for wiring a SINGLE MOTOR VACUUM, or DUAL MOTOR VACUUM under 16 amps, or DUAL MOTOR VACUUM over 16 amps. (When in doubt on amps use the diagram for the larger amps.) Wires are not sold here. Use 14 or 16 gauge wires and put on 1/4 inch flag terminals (all available at hardware stores). Use 12 gauge wire for dual motor setups over 17 amps. To mount it you MUST HAVE 4 x 2.5 inches of space. Do not allow any metal on the relay (besides the bottom) to touch any metal parts on the vacuum except the wires. There are several "feet" on the bottom to use screws (not included) to secure it. #242 Replaces Omron Relays. Has MFG# DP2020A5021.

Low Voltage Booster Box
Splice this booster into a vacuum's low voltage wiring system, plug it into 110 volts, and your 24 volt line will be boosted with plenty of juice! The two blue wires connect to your power unit low voltage (you can use speaker wire to extend any of the wire here) and the red and yellow (or two red) wires connect to the low voltage leads coming from the install site. Simply hang the box on your wall with a nail into a stud. Be sure to use wire nuts to get good connections when joining the wires together.

30 amp Receptacle (for S5 and SV 110 volt)
The plug is called a Nema 5-30 Socket or Plug (for units 110 volt over 20 amps). The large 110 volt plug goes into it. The plug is larger than 240 volt plugs and one prong looks like an "L". This socket fits into and can be used with a single gang box. This receptacle may be hard to find, therefore we suggest buying it along with the unit.

RFX Central Vac Wireless Remote Kit (not RF915)
This is the easiest way to bypass damaged low voltage wiring and remotely start your vacuum unit. Simply install the receiver near the vacuum unit and click the key fob to turn the suction on and off. Surprise - your low voltage wiring troubles are over. Range is similar to a vehicle key fob - about 150 feet depending on wall thickness and barriers. The powerful 400 mhz is sufficient for nearly all homes. Each receiver is programmed separately so you can have multiple systems in adjoining homes and condos. Extra key fobs sold separately. Not compatible with #145 LV11 parts. PDF of RFX Instructions
