● Do not use hemp and grease at the water connections to prevent germ
growth.
● Do not use flexible hoses made from rubber. Rubber hoses offer ideal
growing conditions for bacteria.
● Do NOT use fittings with tapered threads (standard US NPT) to screw
into the UrSpring.
Requirements for mounting the UrSpring:
● Make sure you have a space of 1 x 1.5 meter (wxh) (3.5ft x 5 ft) available
for mounting the UrSpring.
● Make sure that the wall intended for mounting is suitable to carry the weight
of the UrSpring when filled with water (see Specifications).
● Make sure there is sufficient space on the front side of the UrSpring to
allow easy operation of the control unit and allow service and maintenance.
● Make sure that there is 20 cm (8") of space available below the UrSpring to
allow filter replacement.
Requirements for electrical power:
● The power socket must be grounded.
● Distance between socket and the UrSpring must be less than 1.5 m.
● The power supply cable and socket must correspond to the requirements
of the UrSpring (see Specifications).
● Make sure that all electrical connections are compliant with local ordinance
and directives.
● Do not use extension cables.
Requirements for water pipes:
● When using the John Guest quick couplings, all water pipes must have an
outer diameter of 22 mm.
● Water pipes are made of copper, stainless steel or plastic.
When using the John Guest quick couplings in combination with stainless
steel pipes, the pipes must have a groove (see separate John Quest
datasheet).
● Make sure a drain is available. Drain capacity larger than 30 liter/minute (8
gpm).
● Make sure that an outlet such as a sink or drain is available in the filtered
water line. This is required to flush the UrSpring during commissioning.
