DRAIN IV is a HVAC condensate drain line conditioning system that helps prevent bacteria from growing in the drain that forms into clogs. If you live in a climate that you run your air conditioning, you will have condensate that is sent to a sewer drain or the exterior of your home. With aluminum being the makeup on the modern coils, you have a high chance of bacteria festering in your drain line. When unattended to, a clog can form, causing condensate to backup into your system and possibly causing damage to your home.

DRAIN IV can only be purchased from a licensed HVAC contractor. You can contact us and we will refer a contractor that can install DRAIN IV in your home.

DRAIN IV can be purchased by licensed HVAC contractors from your preferred local supply house. Contact us if you are having problems sourcing DRAIN IV.

DRAIN IV is a complementary solution to UVC lights. UVC is a great solution for killing bacteria where the light has direct contact, but UVC does not treat the drain line. We can inject our proprietary solution either into the air handler drip tray or directly into the drain line.

DRAIN IV operating temperature range is 41F to 122F. We recommend that your system be uninstalled in the winter months when the installation environment dips into freezing temperatures.

DRAINIV-IV-BAG-CON-1 concentrate solution is a proprietary agent that is acetic acid based along with other compounds. Our concentrate and other approved fluids must be used to avoid damaging the system and voiding the warranty. Please contact us for the current list of other approved fluids.

DRAINIV-IV-BAG-CON-1 concentrate solution is to be diluted with tap or bottled water.

Empty the 8.5oz DRAINIV-IV-BAG-CON-1 concentrate solution into the 1-gallon IV Bag and fill within 1” from the top of the neck with water. See bottle instructions for details.

PH range of the diluted DRAINIV-IV-BAG-CON-1 concentrate solution is 2.3-2.4.

DRAINIV-IV-BAG-CON-1 concentrate solution, when diluted, has a PH of 2.4-2.6 which is acidic on the PH scale. Most coil/pan cleaners have an alkaline PH which when mixed, will result in a PH somewhere between the PH’s of the two products. Please contact your coil/pan supplier for information about their product safety. Do not mix with strong oxidizers, acids and bases. Do not use without diluting.

DRAINIV-IV-BAG-CON-1 concentrate solution can be purchased at your local HVAC supplier. Please contact us if you have issues sourcing.

The pump has a 2000mAh lithium battery that will keep the programming saved and operate the pump for up to 30 days when powered on and no input power is present. The HOW MUCH and HOW OFTEN settings will determine the length of operation without power.

The battery is fully charged when the level reaches 10 in the HOW MUCH display. See below for details to access the charge level.

On DRAINIV-SYS-1 systems: when the power is supplied to the pump and the pump is off, the battery level will be displayed in HOW MUCH. When the pump is powered on and the display is in sleep mode, the battery level will be displayed in HOW MUCH. The battery levels are 0-10. 0-9 will flash while charging and become solid at 10 when fully charged.

On DRAINIV-SYS-2 systems: The battery level can only be displayed when the pump is powered on. Double press the power button and the battery level will be shown in HOW MUCH. The battery levels are 0-10. 0-9 will flash while charging and become solid at 10 when fully charged.

On DRAINIV-SYS-1 systems: The display will be blank when there is no power supplied to the pump. This happens when the pump is powered off and powered on. When the pump is powered on and there is no power supplied, there is a small flashing blue light on the screen that indicates that the pump is on and in low power mode.

On DRAINIV-SYS-2 systems: The display will be blank when the unit is powered off and when the unit is powered on and there is no power supplied.

On DRAINIV-SYS-1 systems: Sleep mode is when the pump is powered on and the display only shows the battery level in HOW MUCH. To get out of sleep mode to awake mode, press the power button. This will show the programmed values in HOW MUCH and HOW OFTEN. After 20 seconds of inactivity, the unit will go back into sleep mode.

On DRAINIV-SYS-2 systems: Sleep mode is entered when the pump is on and there is no power applied. To wake up the system, press the power button. After 20 seconds of inactivity, the unit will go back into sleep mode.

Press and hold the power button for 3 seconds.

No. To power on the pump, press and hold the power button for 3 seconds.

The pump must be connected to power at all times. The internal lithium battery will retain the programming and operate the pump for up to 30 days. The battery is not intended to be the sole operational power.

HOW MUCH = 30 and HOW OFTEN = 2d. The pump will dispense 30ml (1oz or 1/8^th of a cup) every 2 days, totaling roughly 2 cups a month.

On DRAINIV-SYS-1 systems: Wake up the display by pressing power button once, then double press the -/TEST button. The pump will cycle at the programmed HOW MUCH setting. To stop the pump before the programmed cycle ends, press the power button again and the pump cycle will end.

On DRAINIV-SYS-2 systems: Double press the -/TEST button. The pump will cycle at the programmed HOW MUCH setting. To stop the pump before the programmed cycle ends, press the power button again and the pump cycle will end.

A tight and secure connection at the pump’s IN/OUT ports is required to keep air from entering the connection. The spring clamps maintain this connection.

If HOW MUCH has a number and HOW OFTEN is blank: the battery level is being shown.

If HOW MUCH and HOW OFTEN are both active: HOW MUCH is showing the programmed DOSE setting.

If HOW OFTEN is active: HOW OFTEN is showing the programmed TIME setting.

30 (30ml or 1/8^th of a cup) to 480 (480ml or 2 cups).

30. 1 to 30. 1 day to 30 days.

To get a cycles per month; divide the number of days in the month by the HOW OFTEN setting.

To get the total fluid volume used per month; multiply the cycles per month by the HOW MUCH setting. This result is in milliliters.

• To convert to cups; multiply your result in ml by 0.00422675
• To convert to ounces; multiply your result in ml by 0.033814

Example: HOW MUCH = 30 and HOW OFTEN = 2d, 30 days in the month

• 30(days)/2=15 cycles per month
• 15(cycles per month)*30(ml)= 450ml per month usage
• 1.9 cups OR 15.2 fluid oz

The pump will continue to run on the battery backup until the battery is depleted.

The pump will continue to run at the programmed settings until the battery is depleted. The duration of the depletion is determined by the programmed settings. At the default settings, the pump should continue to operate for up to a month.

Several connection options are included in the DRAIN IV system kit. Choose the best option for your installation.

In most installations the USB cable can share an existing low voltage wiring port and romex connector. If one is not available, a new port and romex connector must be installed.

There are self-tapping screws included in the hardware kit and there are mounting wings on the converter. Select a convenient location and mount. Caution must be taken on the location of the screws.

Double sided tape can also be used.

The converter can also just be loose.

The drip tray and drain line must be thoroughly cleaned prior to install.

DRAIN IV can handle just about any length of an underground condensate line because of our programmable features.

The default programming can handle up to 20 feet in ¾” PVC schedule 40.

6 months is the recommended refill schedule. However, we designed the system to have extra fluid so that the IV Bag doesn’t run out if servicing is slightly longer than 6 months.
