Check your equipment

If connecting your chiller to a KOVE ice bath, you will need the two adapters supplied in the orange accessories tub that came with your ice bath.

Other ice bath or cold plunge setups may require additional adapters.

Safety essentials

• Connect to a properly protected mains supply.
• Test the RCD before first use.
• Never cover the cooling vents.
• Disconnect power before maintenance.
• Keep children away unless supervised.

Included components

• Larger 5-inch particle filter housing
• Smaller hair net filter housing
• Connection hoses and fittings
• Particle filter cartridges
• Filter housing wrench and accessories

Understanding the water circulation

Water leaves the ice bath, passes through the hair net filter, enters the chiller, then passes through the particle filter before returning to the ice bath.

Use the supplied KOVE adapters or suitable adapters for your setup.

Filter positioning

• Mount vertically or horizontally.
• Do not install upside down.
• Use spare washers to adjust the final position if required.

• Mount vertically or horizontally.
• Do not install upside down.
• It may be easier to connect the filter head first.

If installing the filter head separately, apply Teflon tape to the chiller inlet thread before connecting the head, then screw on the bottle section.

Pump running but no water flow?

An air lock is the most likely cause. This is common during initial setup and is usually resolved within a few seconds.

1. Leave the pump running.
2. Slightly loosen the hair net filter housing.
3. Allow trapped air to escape.
4. When water flows continuously, tighten the housing again.

Before your first cold plunge

• All hose connections are secure.
• Water circulates freely.
• Both filters are installed correctly.
• Both ice bath valves are submerged.
• No leaks are present.

Control panel functions

• Power the unit on and off.
• Set the target water temperature.
• View the current water temperature.
• View operating and fault indicators.
• Connect to Wi-Fi where applicable.

Tuya Smart App

Where applicable, connect your KOVE chiller to the Tuya Smart app for remote control.

1. Connect your phone to a 2.4 GHz Wi-Fi network.
2. Follow the on-screen instructions in Tuya Smart. Your chiller should appear as an available device.

Replace the particle filter when:

• Water flow becomes restricted.
• The filter is visibly dirty.
• The filter reaches the end of its service life.

Keep your accessories together

Keep the supplied fittings and filter housing wrench with your chiller equipment for installation and maintenance.

Choose the right position

• Use a solid, level surface close to the ice bath.
• Install outdoors or in a well-ventilated area.

Can the chiller stay outside?

Yes. Your KOVE chiller is designed for outdoor use. Protect it from prolonged direct sunlight and severe weather while keeping the cooling fans clear.

Winter storage

1. Drain all water from the unit.
2. Drain the hoses.
3. Drain the internal pipework.

E18 Error Code

An E18 fault is almost always caused by insufficient water flow.

Check for an air lock, dirty filters, kinked hoses, blocked pipework or low water level.

Pump running but no flow

This is usually an air lock. Follow the air lock procedure in Section 09. Confirm both valves are submerged and the hoses and filters are clear.

Water is not cooling

• Check cooling mode is active.
• Confirm water circulates properly.
• Ensure both filters are clean.
• Check the target temperature setting.
• Consider the effect of ambient temperature.

Before switching on

• Connections are secure and leak-free.
• Both valves are submerged.
• Filters are installed correctly.
• Water can circulate freely.
• Fans have at least 30 cm clearance.

Routine care

Every use: Check leaks and circulation.

Weekly: Clean the hair net filter and inspect hoses and the particle filter.

Storage: Drain the unit, hoses and internal pipework.
