Water supply
9) Drain Connection (WA)
■
For drain connection (Fig. 12) use only steam temperature resistant pipe,
diameter 2 in. (50 mm) and constant slope 5%. No hose should be used.
■
Direct drain connection is possible, ventilated gap is an integrated part of the
appliance (Fig. 13).
■
Drain pipe should be supported to the wall/floor.
■
Max. water discharge rate during Auto Flush:11 gal./min. (0.7 liter/sec.)
■
Average drain water temperature: 150°F (65°C).
10) Water Connection (WZ)
■
Observe all local plumbing codes.
■
Flush water line before connecting the water supply to the unit.
■
Connect to cold, potable water only.
■
Operational water pressure: MIN: 30 psi (200kPa) MAX: 88 psi (600kPa).
RECOMMENDED: 44 psi (300kPa). Water flow must be at least 3 gal/min
(12 l/min).
■
Water connection supplied by customer:
1
⁄
2
in. pressure hose with R
3
⁄
4
in. tapered
fitting.
■
Customer fitted shut-off valve for each appliance.
■
Water conductivity: 50-2000 µS, lower conductivity on request.
■
Maximum chloride concentration (Cl-): below 150 ppm (150 mgr/liter)
at any time.
■
For conductivity above 2000 µS or higher chloride concentration use
hydrogen-ion exchanger (A in Fig. 15) in the supply water line.
■
Water Redox-Potential must be below 300mV at any time.
■
For higher Redox Potential use Active Carbon Filter (B in Fig. 14). Observe
maintenance period of active carbon filter.
■
Use a 3 micron (0.08mm) particle filter (C in Fig. 14) to prevent excessive
soiling of the supply water.
■
Recommended test instruments: Cl2 Tester (swimming pool accessories),
conductivity tester, redox meter.
Optional Treated Water Connection
■
To connect a dual water supply–treated soft water or warm water below
■
140°F (60°C)–disconnect T-water connection at the two water inlets (Fig. 15).
Connect treated water to water inlet marked WZ2 and standard water to inlet
marked WZ1. Treated water must comply with the above-mentioned water
specifications.
NOTE:
If using external filter to treat hard water: Contact your Henny Penny
distributor for average water consumption when using CleanJet. Increases in
average water consumption may exceed specifications of external filters and may
affect the frequency of filter maintenance. (See page 57)
