Can I keep my Modtub outdoors?Updated 11 days ago

Yes — the Modtub is suitable for outdoor use, but it must be protected from direct sunlight and freezing temperatures to maintain performance and avoid voiding your warranty.

We strongly recommend placing your Modtub in a shaded or sheltered area such as under a patio, deck, pergola, or umbrella. Prolonged exposure to direct sunlight can cause warping and damage and will void the warranty. For this reason, never leave the tub in direct sun for extended periods — especially when empty or not in use.

The chiller should also be shielded from weather exposure like rain, snow, and excessive heat. A covered and ventilated location is ideal. If your unit is outdoors and covered, make sure the chiller has adequate airflow.

Damage from freezing or sun exposure is not covered under warranty, so please be proactive in protecting your Modtub if kept outdoors. This is just our suggestion, as some customers have had their unit outdoors, uncovered with no issues. 

Freezing and Winter Weather

In cold climates, you must take precautions during freezing temperatures. We recommend using the chiller bypass hose and relocating the chiller indoors when temperatures drop below freezing. If running the unit outdoors in cold conditions, always keep the pump running and check that your filters are clean. For maximum water flow, you may remove the filter entirely to reduce flow restriction and help prevent freezing.

From our experience through two winters, we have only experienced damage to the filter housing due to freezing. This is likely because the filter itself can slow down the flow, and especially when it is clogged. This is why removing the filter cartridge during below freezing temperatures will significantly decrease your chances of freezing.
