General Guidelines

WARNING

Ensure the power is not connected or on when adding or changing the water to the water circuit. There is a risk of electric shock, which will cause

physical injury or death.

Install the Hydro Kit and the water circuit in a secure location where it cannot be accessed without authorization.

• Follow all applicable local, state, and federal codes if / when insulating the Hydro Kit water circuit.

• Clean the water piping and connections with water.

• Include enough installation and service space for an external water pump.

• Use anticorrosive copper pipe for the water piping.

• During piping installation, keep the end closed with a cap to prevent dust and other impurities from entering the piping.

• To prevent the piping connections from mechanically failing, apply industry-standard tools and follow local, state, and federal codes regard-

ing installation methods.

• Ensure all piping connections (L-shaped elbows, T-shaped fittings, diameter reducers) are tight and free from water leaks. Seal all piping

connections with Teflon

tape, sealant, joint compound, rubber bushings, etc.

• Insulate the piping to prevent heat loss, and to avoid generating condensate.

• Operation time of flow valves (examples: three-way valve or two-way valve) must be less than 90 seconds.

Water Quality

Water quality must comply with local or national codes. Read all cautions and warnings before adding antifreeze to the Hydro Kit water circuit.

• Clean all water piping to remove sludge and scale. If the Hydro Kit is to be installed on an already existing water circuit, clean out the water pipes

•

DO NOT charge or operate the Hydro Kit water circuit without the strainer installed. Installing a strainer in the water loop is very important to

prevent performance degrade.

• Perform chemical treatment to prevent rust. Any chemical treatment to prevent rust must be performed by a trained technician.
