How does the temperature setting affect the unit when it is set to dry mode. It seems like it "dry's" to be much cooler than the setting

The DRY mode works by making the indoor coil extra cold and slowing down the fan speed very low. This is so that it can draw out as much moisture from the air as possible.

Do the lines come flared? Or do i only have to flare them if i want a custom length?

They arrive pre-flared from factory. If you shorten them then you would need to reflare the ends.

Does this have an energy star rating? What is the average usage per month?

Yes this is Energy-Star certified. 

• AHRI Estimated Yearly Operating Costs:
• Cooling: $148.00
• Heating: $505.00

What is the AHRI number for this unit?

It is 8819852, for more info see here: https://www.pdhvac.com/site/downloads/certificates/certificate_WYS024GMFI22-205.pdf

What is the lowest outdoor temperature the unit will work at when used for cooling

For COOLING mode it would be 5°F.

How many amps does the 2400 BTU draw?

This system draws 8.4A in cooling and 11A in heating. It requires a 25A double-pole breaker with 12 AWG wire.

Does the indoor unit have to be mounted on exterior wall?

No, it can be mounted on an interior wall. However, you would need to route the condensate drainage into a nearby sewer pipe from a kitchen or bathroom, or implement our condensate pump to route the drained condensate elsewhere.

Should this have a fusible disconnect, or is the breaker in the main panel sufficient?

Any disconnect whether fused or unfused will do, it will just act as a pullout switch for servicing. But ultimately the breaker in the circuit panel will be enough.

what is the lowest temp heat pump will work

This system will continue heating down to -13°F outside temperatures.

Ordered the system with a 16ft line set ,will a 10ft line set work without a problem?

That would not be a problem at all, the included pre-charge can support line lengths between 10 and 25 ft.

Will this unit work on 240 volts?

Yes, it can work on anywhere between 207~253V.

On this unit 24000 21.5 seer how many sq ft will it take care of

This is intended for spaces between 650 and 950 square feet.

How loud does the unit sounds? I am looking for a quite unit to install in a spa environment. It can not run louder then the relaxing music. Please explain!

These systems are ultra silent and barely audible. The 24K unit on low is about 35 dB, which is actually quieter than a library. You won't even believe it's on unless you put your hand over the vent to feel the air.

What size are the coolant lines, not length?

This system takes 3/8"-5/8" diameter lines.

What’s the amperage and recommended breaker size? Does this unit require a neutral wire?

This system would take a 20A double-pole breaker with 12 AWG wire. The wire would be two hots and a ground, no neutral.

What temperature does efficiency start to drop off at? For I instance at 20 degrees is it still at 100% Efficiency, whsf?

You can see the heating performance curve here.

Can this be connected to a thermostat?

There are currently no wired thermostat options available, the closest solution would be this wireless smart controller which can act as a thermostat for all intents and purposes.

What are the wifi options?

You can either consider our internal WiFi module or a dedicated discrete smart controller device. Both would provide scheduling functionality and ability to control remotely from your smartphone.

What is the max height the outdoor heat pump can be mounted? Can I mount it 3ft above the ground

The outdoor unit and indoor unit should not have a height differential greater than 16 ft.
Otherwise, mounting the outside condensing unit 3 ft off of the ground is not a problem.

What will be the problem if the top of the inside unit is only 2 inches from the bottom of a vaulted ceiling? That would only be a 2 inch clearance and not the 4 to 6 that is recommended.

This will restrict the return/intake air and severely diminish performance. The unit pulls in air from the top before conditioning it and sending it back out through the bottom louver.

What amp circuit breaker is required for your 24k unit

This would take a 25A double-pole breaker. The corresponding wire would be 12 AWG, with 2 hots and a ground, no neutral.

do your units come pre-charged with Freon?

Yes the outside units are factory pre-charged for up to 25 feet of lineset attached.
