Align the dust protection pipe (11) to ensure that possible air drafts cannot
blow away the fine chlorine dust. (Distance from the upper edge of the
protective tube to the dosing hopper approx. 1-2cm).
5.2.4
Bleeding the motive water pump
Carefully bleed the pump and piping of the GRANUDOS PLUS before switching it
on. The following must be considered during installation and commissioning to
prevent the operating pump of the GRANUDOS PLUS from running dry:
1.
Changes in the incline and decline of the supply line piping must be avoided. This
may lead to trapped air that can reach the pump during operation.
2.
It must be manually checked whether the rotary pump can easily be turned.
Check the shaft for ease of movement by turning the fan wheel at the rear with
a screwdriver. The floating ring seal is clogged when the shaft cannot be easily
turned. Try to loosen it by jerking it backwards and forwards. The pump must
be removed and disassembled in case this is not possible. Failure of the pump is
inevitable when the pump is switched on while the floating ring seal is blocked.
3.
Open the ball valve at the water intake and the supply valve at the pre-filter
when starting up the system. Press the intake solenoid valve by hand until the
rinsing tray is half full. This ensures that water has run through the pump and
that the pump is bled. Thereafter, open the stop valve upstream of the cyclone.
Only then switch on the GRANUDOS PLUS.
4.
The piping to the GRANUDOS PLUS must be carefully bled before switching
on. Take note of the d75 pre-filter. When the water level in the filter drops
significantly after the pump is switched on, switch off the GRANUDOS PLUS,
open the bleeding screw on top of the filter, let water run into the filter and
then switch on the machine. It might be necessary to repeat the process a few
times until the filter remains filled; a few air bubbles in the upper area of the
filter are not relevant.
5.2.5
First filling of the buffer tank of the feed system
Requirements:
The GRANUDOS PLUS system has been completely connected and the water
supply is ensured. The chlorine drum has been put in position and the suction set
for the acid has been connected to the canister.
The start-up programme:
1.
Switch on the device at the main switch.
2.
Switch off dosing by using the Dosing off button. The start-up programme is
automatically activated by the Level min. alarm switch. The GRANUDOS PLUS
fills the buffer tank without chemicals. Fault messages of the feed system are not
taken into account.
3.
The
water flow in the dissolving system
and the
water level in the rinsing tray
must be set during this time.
(See Section 5.2.6 and 5.2.7)
.
4.
After 10 minutes, the GRANUDOS PLUS automatically switches off. The water
level should now be above the pressure socket of the feed pump. The display
shows the message: Has the required level been reached? Yes or No .
5.
When the required level has not yet been reached, acknowledge with No and
the buffer tank will be filled for another 10 minutes, when the device will again
