Installation
Attention
If due to a leak at the JUDO UNIDOS digital dosing pump system severe damage could
result, a suitable JUDO bund (see Chap. 3.2.3) should be used as a safety installation!
4.1
Requirements for the place of installation
The JUDO UNIDOS digital dosing pump system must be installed in a dry, frost-proof location with a
condensation-free and non-aggressive atmosphere.
A site ½“ i.d. connecting sleeve must be provided for the cold or hot water injection point.
An electrical connection (constant voltage, site provided socket) must be provided in the immediate
vicinity of the JUDO UNIDOS digital dosing pump system.
If the JUDO UNIDOS digital dosing pump system is equipped with an electrical stirrer, a further
electrical connection (constant voltage, site provided socket for the JUDO timer clock JZS U/E) must
be provided in the immediate vicinity.
A clearance of 50 cm for maintenance and repair work must be available above the JUDO UNIDOS
digital dosing pump system.
4.2
Installation notes
If there is an clear outlet for the dosing medium or if the system-induced back pressure
< 1 bar, a JUDO pressure holding valve JDHV-DOS (see Chap. 3.2.3) should be fitted
immediately before the outlet point or injection unit (not necessary under normal
circumstances when using original JUDO cold or hot water injection points, in case of
doubt, obtain technical advice)!
To protect against overpressure, a JUDO overflow valve JÜV-DOS (see Chap. 3.2.3)
should be fitted in the dosing line, the return line must be fed back to the dosing tank
with a clear outlet!
If necessary a JUDO multifunction valve JMFV-DOS (see Chap. 3.2.3), which combines
the functions of a pressure holding valve and an overflow valve, should be fitted directly
at the high pressure-side connection of the dosing pump; the return line must be fed
back to the dosing tank with an clear outlet!
Preliminary remark about chlorine dosing:
For reliable sterilisation a reaction time of approximately 30 minutes between the chlorine and the
water to be sterilised is necessary. To ensure that the water remains in the water pipe sufficiently long before
drawing, the JUDO UNIDOS digital dosing pump system is optimally to be installed upstream of an
adequately sized compressed air chamber.
