OPERATION
• Stable mixed water temperatures.
• Anti-scalding safety: Hot Water supply shuts off if the Cold Water supply fails.
• It is possible to undertake thermal and chemical shocks: see paragraph "Thermal and Chemical Shocks".
TECHNICAL FEATURES
•
733015 - 733016: 19 lpm at 1 bar
, for 2 - 7 valves depending on the flow rate of the valve
(NB: TEMPOMATIC, TEMPOSTOP… at 3 lpm).
•
733020 - 733021: 23 lpm at 1 bar
, for 2 - 10 valves depending on the flow rate of the valve
(NB: TEMPOMATIC, TEMPOSTOP… at 3 lpm).
•
Integrated non-return valves and filters.
• Stable temperature: ± 1.5°C between 34 and 40°C.
• Pre-set at 38°C (HW and CW pressure 3 bar).
• Temperature adjustment from 34 to 40°C.
•
Anti-scalding safety active if:
- the mixed water temperature is lower than 42°C.
- the temperature differential between the HW and MW is greater than 15°C.
- response time ~5 sec.
INSTALLATION
• Recommended pressure: 1 - 5 bar.
• Hot Water supply temperature: 55 - 85°C (the temperature differential between the hot water
and the cold water must be at least 50°C).
• Cold Water supply temperature: 5 - 20°C.
• Balance the pressure between HW / CW (ΔP<1 bar)
•
Do not remove the filters and non-return valves incorporated in the water inlets.
• Connect the water supply using either nuts with a compacted flange or a flat faced tap connector.
Connect Hot Water to the red ring
g
and Cold Water to the blue ring

.
• PREMIX Compact can be installed in any position (
fig. B and C
).
REMEMBER
•
Our mixers must be installed by professional installers
in accordance with current regulations
and recommendations in your country, and the specifications of the fluid engineer.
•
Sizing the pipes correctly
will avoid problems of flow rate, pressure loss and water hammer
(see calculation table in our brochure and online at www.delabie.com).
•
Protect the installation
with filters, water hammer absorbers and pressure reducers to reduce
the frequency of maintenance (recommended pressure from 1 to 5 bar maximum).
•
Install stopcocks
close to the mixer to facilitate maintenance.
• The pipework, filters, non-return valves, stopcocks, bib taps, cartridge and all sanitary fittings should
be checked at least once a year, and more frequently if necessary.
COMMISSIONING & LOCKING THE TEMPERATURE
• To set the temperature (
fig. D
) :
- Remove the covering cap
a
.
- Loosen the locking screw
b
using a Phillips screwdriver.
- Remove the control knob
c
by hand.
- Slowly turn the notched spindle
d
until the desired temperature is achieved at the point-of-use.
Avoid any disruption to the system during commissioning.
• Replace the control knob:
- either in the open position (
fig. F
).
- or the
locked position
(
fig. G
): replace with the control knob
c
upside down.
