5.4. Water connections
Water connections of the Proveno combi-kettle can only be carried out by a person with professional
competence in the installation and service of heating, plumbing and air conditioning equipment.
The location of the water connection points appears from the installation drawing. Both cold and hot
water connections must be fi tted with a closing valve and a non-return valve (not included in delivery).
The sizes of water connection points are as follows:
Cold water: connection with R1/2” outerthread, supply with min. 15 mm inlet pipe
Hot water: connection with R1/2” outerthread, supply with 10 mm inlet pipe (max. +60°C)
If the cold water inlet pipe is smaller than 15 mm, water fl ow will decrease and the fi lling times will be
longer than indicated.
• Cold and hot water supply lines must be fi tted with a one-way valve and a shut-off valve (not included
in delivery).
• Before connection to the unit all water lines must be thoroughly rinsed from all loose particles.
• The water pressure range for optimum performance is 250 - 600 kPa.
• The minimum water pressure allowed for proper function of the unit is 250 kPa.
