Waterlogic 1000 GF Technical Manual - Issue A, July 2011
SANITISING
6 Month Sanitisation Procedure
Please ensure that you do not accidentally drop sanitizer fluid on any of the WL
1000 GF’s water or electrical connections or allow sanitizer to enter the hot tank.
1.
Turn off the water supply and isolate the power to the WL 1000 GF and remove
the machine top cover and the lower front panel.
2.
Remove the header tank cover.
3.
Carefully drop one Chlorine tablet into the header tank and allow it to dissolve.
4.
Flush the cold water and the ambient water until Chlorine is observed dispensing
from the cold and ambient faucets. Please do not flush the hot water. Chlorine
water must not enter the hot tank.
5.
Allow the Chlorine to have at least 20 minutes contact time with the cold tank,
the water pipes and faucets. This time could be used to carry out any service work
required on the machine.
6.
Turn on the power and water to the machine. The machine will start to auto fill
the header tank.
7.
Flush the cold water and ambient water until all traces of Chlorine are removed.
Chlorine test strips can be used to verify this.
8.
Replace the top header tank cover, the machine top cover and the machine
front lower panel.
9.
Clean all outside surfaces of the machine, including the front water dispensing
area. Remove and clean the WL 1000 GF’s drip tray and grill.
FAULT FINDING
All fault finding procedures must be carried by a technician trained by Waterlogic
International or their nominated distributor.
Please take great care and suitable health and safety measures when fault finding
on live electrical parts.
1. No flow of water
: Ensure that there is a water supply to the WL 1000 GF from
the building and that the installation isolation valve is turned on. If the installation
kit has an anti-leak device included in it (as Waterlogic Installation kit) then make
sure it has not tripped.
2. No flow of water:
Check that the water filters and membrane are not blocked
and that they are in date and are fitted securely into the 1000GF. Waterlogic
recommend filters are changed at 6 months. Check that the internal leak detection
tray has not filled with water as this will turn off the water inlet valve.
3. The hot water is not hot and cold water is not cold:
Make sure the green
and red heater and compressor switches are turned on. Check that the machine
power indicator light is on.
4. There is hot water flow but cold water is not flowing:
This may be due to
the cold water tank being frozen. If so, disconnect power supply for one hour to
allow the tank to defrost, and then flush the cold water system. Check the cold
thermostat settings are correct (5ºC). If the cold tank is not frozen then check
the mechanical water outlet faucet valve is operating correctly the water flows
through it.
5. There is cold water flow but hot water is not flowing:
Check the pipes feeding
the hot water tank, check the mechanical water outlet faucet valve is operating
and the water flows through it.
6. Low flow of cold water or hot water or both:
Check the building water pressure
to the WL 1000 GF is 45 PSI. Check that the Reverse Osmosis pump is running
and that the filters or membrane are not partially blocked. Also check that the inlet
solenoid functions, that the mechanical float valve is functioning correctly, the
header tank is full and water flows in to the hot and cold tank. During excessively
high machine usage the header tank water level may be low and this can affect
the water flow. Please remember that the Reverse Osmosis system will need time
to refill the header tank. Check the outlet mechanical water faucet valves and the
feed pipe to them is not kinked.
7. Bad or plastic taste:
If the WL 1000 GF is new it may need flushing for a longer
period.
8. Water leaks:
Most leaks will be detected by either the internal WL 1000 GF leak
detection system that will trigger or turn off the inlet solenoid valve, or it will trip
the Waterlogic block located on the installation kit. Should you see water leaking
from the WL 1000 GF, isolate the supply and start normal fault finding procedures.
9. No power:
Check the building electrical supply to the WL 1000 GF is on and that
the power cord is plugged in. Ensure the power indicator light of the WL 1000 GF
is on. Test the WL 1000 GF fuse. Start normal electrical fault finding procedures
using the electrical circuit diagram.
10. Water pump won’t run:
The Reverse Osmosis water pump will not run or it will
keep turning on and off if the water pressure drops below 1.5 bar.
11. Not Chilling:
Check the ambient room temperature: if it is above 32 ºC the
refrigeration system will not function.
