*Introducing the Aprilaire Model 500M Humidifier!

 The Aprilaire Model 500M is a by-pass humidifier. The 550M is a great whole house humidifier! I have installed many of them. The 500M humidifier does an excellent job! The 500M Humidifies a home up to 3000 square feet! The 500M comes with (please see picture below) 5' of 1/2" drain hose, 20' of 2 conductor thermostat wire, stock #10 water panel, humidistat, self tapping water valve, transformer installation instructions, owner's manual, and plenum hole template. *The 500M requires 6 inch round pipe to connect to the return air for supply air. The 6" round duct is not furnish, but can be purchased at almost any home supply store. You would also need to purchase some 1/4" copper tubing to connect the water supply to the humidifier. We double-box all humidifier orders to protect the humidifier during shipping. The box is over-sized and rated by UPS at 29 lbs. We rate it at 25 lbs to try and save you on the shipping.

Humidifier Installation Accessories:

Below are listed some of the accessories and supplies you might need when installing your humidifier. If you furnace has a humidifier (HUM) terminal on the control board then you will not need the A50 current sensing relay.

One accessory that I use on many of my humidifier installations is a Current Sensing Relay. This nifty little relay allows me to quickly set up the humidifier to run only when the furnace blower is running. This eliminates the need for a sail switch or more complex wiring. The relay attaches around the white (most of the time) common lead of your furnace blower motor. When the blower comes on it senses there is current and turns your humidifier on. It is easy to install and comes with complete wiring directions and instructions. The A50 current sensing relay acts like a 24 volt switch. The A50 is not designed for 110 volts. You would need the A51 current sensing relay if you plan on running 110 volts through the relay.

*A special note of concern

 If you are not familiar with electrical wiring, sheet metal, and plumbing principals, then I would strongly suggest that you leave the humidifier installation up to a professional. Bodily harm, heating and air conditioning equipment damage, and damage to your home may result if you do not understand these principals. I Steve Arnold, want to help you save money, and most certainly do not want to see anyone get hurt or damage their property.

 

Humidifier Installation Supplies List: You will probably need the supplies listed below to install your humidifier. 

bullet  

1/4" copper water supply tubing at least 10'.

bullet  

Plumber's Teflon tape to wrap around the threads of the water saddle valve before you screw it into the body of the saddle valve. This will prevent a leak around where the valve screws into the body.

bullet  

18 gauge thermostat wire. Probably about 20'. This is supplied with the humidifier by us free. It is better to have too much than not enough. You will use this to wire between your humidistat, low voltage transformer and back to the humidifier.

bullet  

Electrical-(1) outlet box with romex connectors.

bullet  

 #14-3 house wire. You probably will not need over 3'. I use the 14-3, sometimes to run from the furnace board (when 110 volts are provided on the furnace board) over to an outlet that is attached to the side of the furnace. You can also use the wire to run into a junction box that powers the low voltage transformer when installing the model 500 & 600 humidifiers. You must drill a hole in the blower compartment of the furnace and use a romex connector to protect the wire from being cut by the body of the furnace. I use a metal cutting hole saw to drill the hole in the body of the furnace.

bullet  

 3/4 PVC fittings & PVC cement: You will probably need at least  4-90's, 2-couplings and 1-tee.
