Transcript:

So this is a MACH-145 12 ton unit. Basically how this is set up – you have two supplies, you’ve got two returns and you have your exhaust on one side of the unit.

On your supply and return, you could have a 150-foot of duct maximum on these units – obviously I recommend shorter is the best. But maximum you can run 150-foot of duct through four hits.

On the exhaust side you have a supply and return; which is an 18-inch hit, so it has bigger holes – allowing for that if you’re trying to exit the off exhaust air.

Then you have your support; that’s your supply, so blowing out the hot air here and pulling in cooler air here. These can both be ducted – again cumulative 150-foot of ductwork.

A common rule with all the duct: you always want to have straight as possible, as little kinks as possible, no swooping turns.

Also you have a pump that you can add optionally to the unit, which can be gravity-fed. This is a P-trap- they come in the unit and are usually sitting in the electrical supply door at the bottom.

After you start this unit up for the first time- after the first ten minutes or so -I recommend priming the P-trap. Stick your finger over your thumb (or a finger) to cover up the hole of the p-trap to allow the pressure to change. Give it about a minute or so, release your finger, and this should allow the water condensation to fill it up inside to release outside here and then you would end up putting your pump in.

It does have the option of a remote thermostat if you don’t want the unit measuring return air – it’ll actually slave this thermostat and allow you to run the thermostat off the plug.
