How to Use Your 4 Person Inflatable Hot Tub (Official Usage and Safety Instructions)
Modern inflatable hot tubs, such as CO-Z inflatable hot tubs, are designed with durable, insulated materials that help retain heat, making them suitable for year-round enjoyment. Let's take the CO-Z's 4–6 person inflatable hot tub as an example to illustrate how to use a 4 person inflatable hot tub properly and safely.
STEP 1
Prepare the location and install the spa. Prior to installation, ensure that the spa’s setting will be appropriate for use. It must be flat, stable, able to easily bear the weight of the fully-filled spa, resistant to high humidity, and out of direct sunlight. Adequate drainage and ventilation must be provided, and all metal surfaces and electronic devices must be kept at a suitable distance.

NOTE: It is advisable to display warnings on the spa for all potential users. A safety precaution sticker, suitable for outdoor use in humid environments, is included in the package. Before initial use, remove the release liner from the sticker and affix it to a prominent position on the spa. If needed, you can contact CO-Z's customer service for extra copies or replacements.
STEP 2
Fill the spa with water to a level between the minimum and maximum fill lines marked below the control panel. Use preheated water 104°F (40°C) or cooler or cover the spa, lock the cover, and wait for the water to heat to the correct temperature.
STEP 3
Press the HEATER button to activate the filtration and heating systems. The default target temperature is 104°F (40°C). Press TEMPERATURE and use ⯅ and ⯆ if you want or need to set a lower temperature. Cover the spa and lock the cover if you will need to wait for it to heat or need to leave the activated spa for any reason.
STEP 4
When the water is at your target temperature, remove the cover and enjoy your spa, activating the jets as needed with the BUBBLE button. Do not exceed the capacity for the spa, do not allow children younger than 8 into the heated spa, and do not leave older children unattended at any time. Ensure they and any other users understand and observe ALL the rules described in the Safety Information above.
NOTE: DO NOT use the spa for longer than 10 minutes at a time at its highest heat settings and leave the water IMMEDIATELY if at any point you begin to feel drowsy or uncomfortable.
STEP 5
The filtration system does not need to be continuously active during use, but its circulation of the water is necessary for as long as the heater is active. The jets may be used as needed, but remember that they can only be used continuously for 20 minutes at a time, after which the system will lock out further use for a 10 minute rest period. Do not run the filtration or heating system longer than 48 hours continuously, and cover and lock the spa at any point when it has water but cannot be attended.
STEP 6
When you are done, you can leave the spa inflated and full of water so long as it is securely covered and locked in a suitable location out of direct sunlight without any possibility of freezing or near freezing temperatures. Be sure to use appropriate chemicals to maintain the water’s safety, run the filtration system periodically to circulate everything, and change the water at least once a month. Alternatively, fully drain, clean, and dry the spa between each use.
NOTE: NEVER leave the spa accessible to unsupervised children or exposed to low temperatures. In temperate climates, fully drain, clean, dry, and store the spa (see below) each autumn and do not reinstall it until spring temperatures are consistently warm.
STEP 7
To drain the spa, dry your hands, turn off the spa by pressing TEST (yellow) on its power plug, and disconnect its power cord from power.

Remove the cap of the drain inside the spa and keep an eye on the spa as it drains. When the spa is mostly empty, dry your hands, reconnect it to power, reactivate it, press BUBBLE, and allow the jets to clear water from their line for at least 5 minutes. Do not run the filtration or heating system at this low water level and do not tip or angle the pool to speed draining until it is almost completely empty. When all water has drained, close the drain.
NOTE: In the event of blockage, leakage, or other problems during this process, IMMEDIATELY replace the cap of the drain and correct the problem(s) before continuing to drain the spa or allow time for it to air dry.
