• SeltzaHub
• SeltzaTap / SeltzaTap Compact
• CO2 canister (purchased seperately)
• Electrical outlet under sink

• Each of Seltza's product specs are provided on the individual product page by clicking the button marked "specifications."

• We estimate 50% of our customers install the system themselves and 50% use a plumber to install.
• Some customers have reported installing the system within 30mins and others a few hours. We believe it depends on your experience and comfort with such processes.
• Be sure to review how to properly use quick-connect fittings - there are many videos online.

• Seltza provides a 1 year warranty, as well as ongoing support if issues arise.
• Seltza provides a 100 day trial with free returns, if the carbonation does not meet your expectations. The trial applies if you purchase a SeltzaHub along with a Seltza faucet, as we cannot guarantee the carbonation of a third-party faucet.
• Other return information can be found in the Refund Policy

• If product is in stock: most customers receive their order within 1-2 weeks, but delivery times are not guaranteed.
• If product is out of stock: the estimated timing is shown below the pre-order purchase button. Please note this is a best-estimate and not a guarantee.

SeltzaHub is meant to be placed under the counter. The dimensions of SeltzaHub are below. Please confirm you have enough free space under your counter.

• Height: 40cm (15 3/4")
• Width:  23cm (9 1/4")
• Depth: 43cm (17")

• SeltzaHub does not include a filter.
• A filter is optional; not required for the system to work.
• The SeltzaRO Water Filter is available for purchase.
• If you already have a filter, most are compatible with the SeltzaHub

• Yes, water filters, including RO filters, can be installed before SeltzaHub.
• It's important to ensure your filter has an outgoing pressure of minimum 20psi.

• Yes, softened water is ok for SeltzaHub. SetlzaHub does not include cooper which makes it safe for use with softened water.

• Generally venting is not required for SeltzaHub. The SeltzaHub design produces very little heat making it safe to install under the sink without ventilation.

• Yes, a standard 120v electrical outlet is required.

• The Hub unit does not require maintenance.

• TR21-4 (threaded SodaStream style)
• CGA-320 (5, 10, 20lbs)

• We recommend the largest tank that you can fit in your space. The larger the tank the lower the price per glass of Seltza water.
• Common tank size are SodaStream bottles, 5lbs, 10lbs and 20lbs tanks.

• There is no specific distance limitation when installing your CO2 tank. Customers have installed CO2 beside SeltzaHub, in a corner cabinet, or even in the basement with a hole drilled through the bottom of the cabinet.
• There is a booster pump in the SeltzaHub for sparkling water. Note that there is no booster pump for the chilled-still and ambient-still lines, so they could experience a flow-rate drop when the Hub is further away than 10 ft.
• If you plan to install your CO2 further than 3 ft from the Hub, contact us for specs on what tubing you will need to purchase.

• CO2 tanks (5, 10, 20lbs) can be purchased at home brew, beverage gas, hydroponic and wine-making shops.

• When your CO2 canister has run out of gas you will be required to replace/exchange it. The CO2 canister is connected externally and replacing it is a simple process.
• The washer inside the tank's CGA-320 regulator adapter also needs occasional replacement. Often people do this when exchanging their tank.

• Some third-party faucets will work with the SeltzaHub. In our experience most of those are beverage faucets that will provide the sparkling water only.
• Some third-party faucets do not produce an adequate level of carbonation. We recommend emailing us at hello@seltzatap.com to discuss what faucet you hope to use.

• Seltza currently does not have an instant hot water feature available.

• The cartridge is a wear part that requires occasional replacement. This is a simple task.

Keep your extra parts!

• If you have a spare faucet cartridge, keep it for future maintenance use.
• If you have a Compact Tap you have optional aerators to adjust carbonation and flow.

• It's key to ensure lines are fully inserted into fittings.
• Quick connect fittings need to be inserted past the point of pressure (approx 5/8" deep) for a perfect seal.
• For disconnecting & reconnecting, there are many videos online that show how to use quick connect fittings to prevent any damage.

Here are some tips for finding the right carbonation for you:

• After the installation start-up process, allow a few days for the Hub to fully carbonate. Use/flush the sparkling water during this time.

• Always run the sparkling line for a second before putting your glass under it. This will flush out the water sitting in the line.

• Increase CO2 pressure (max 75psi). Recommend starting at 65psi and adjust as needed.

• Decrease the internal Hub temperature to 2 degrees celsius. Recommend starting at 4 degrees and adjust as needed.

Note adjustments can take time and flushing to experience the new level of carbonation.

• Complete an aerator replacement, as shown in this 1 min video 
• Contact us if you don't have our latest and greatest aerator!

• The valve on the left hand side may not be fully seated. Adjust - there is a quiet "click" - and check that the dripping stopped.
• If dripping persists please contact hello@seltzatap.com. It might be time to replace your cartridge.

• Make sure the regulator is turned the right direction: clockwise to increase pressure. This can seem counterintuitive.
• Confirm that the tank is turned fully on and that there is adequate CO2 in the tank.
• Check the washer inside the CGA-320 (large tank) adapter for damage. These require occasional replacement.
