WaterMark Quality System Doc # RQS.1059
RM5000 & RC550 Submersible Pump System with
RainPro RM4000-3 Rain to Mains Backup Valveset
How the system works;
1.
When the Rainwater tank is empty/nearly empty, the pump controller will sense there is insufficient water
and turn the pump off (or for submersible pump with float, the float switch will turn the pump off)
2.
When this happens, the submersible pump shuts down.
3.
Mains water (Town-
Water) will flow freely so you always have water when the Rainwater is “off”.
4.
Some pressure difference may be noticed between the different water supplies
–
this is normal, it is not a
fault with the system
–
the mains water will be at lower pressure than the rainwater supply.
5.
Occasionally toilet cisterns might make some strange noises due to some air coming through the pipes, this
will do no harm, and is a normal part of the automatic operation.
6.
The pump will attempt to re-
start several times over the period of a few minutes. The pump might “crackle
& gurgle” a bit due to air in it, as it tries to restart, this is not a fault, it is normal.
7.
If the pump cannot get enough water it will then stay off for 24 hours, then repeat the same process every
24 hours to check if there is water in the tank.
8.
If it happens to do this in the middle of the night it can be annoying! In the morning, turn it off & on again
after 30 seconds and it will reset itself so it does the checking in daylight hours.
9.
6 to 8 are not applicable for a submersible pump with float switch, it will stay off until the tank fills again.
10.
If it is dry for a long time - no rain - it is best to turn the power off to the pump, at the power outlet.
11.
A “First
-flush-
diverter” or similar device must be installed to prevent debris from entering the tank, or
a filter screen through which all the incoming water passes before entering the tank.
12.
Sometimes even after rain, there might be an air-pocket in the pump and it does not restart. This is
NOT a warranty fault!! Simply turn the pump off at the power outlet, and back on after 20 seconds, repeat
until water flows normally. If this does not work, you may need to either: Turn the mains off using the
MAINS ISOLATION VALVE (see front page) and restart the pump.
13.
IMPORTANT
–
Leak Detection Function
: If the pump is turned on & off more than 7 times in 2
minutes, it will automatically switch itself off completely. THIS IS NOT A PUMP FAULT!! Find, isolate and fix
the leaking item
–
toilet cisterns are always the first thing to check
–
some leak internally into the cistern
and DO NOT TRICKLE INTO THE PAN
–
turn the stop-cock off under the cistern, to check for sure.
14.
Before assuming there is a fault with the pump operation, check the water level in the tank, the pump
may not operate unless there is 300 to 700mm of water in the tank, note that tank-level indicators are not
always reliable (water level required is dependant on the type of pump & the installation, also see the
important note below)
IMPORTANT!! FOR PUMPS WITH FLOATS:
The water level will need to be 0.6m to 1.2m high inside the tank,
for the pump to start.
