NON-STANDARD SYSTEMS  
 

Finally, please note there are also available a number of non-standard systems.

 

You should have consulted 

with ENVIREAU and be fully familiar with your own requirements, particularly regarding EXTRA items of 
equipment. You should be 

aware

 of your requirements regarding 

NON-STANDARD SYSTEMS before 

commencing installation.

  

 
If you are 

UNSURE 

of these requirements 

READ THE RELEVANT INSTRUCTIONS IN THE NON-

STANDARD SYSTEMS document

.  

 
The additional document entitled 

NON-STANDARD SYSTEMS

 will cover the following:  

 

a)   Interfacing with Building Management Systems (BMS) 
b)   PUMP LOCK-OUT MODE (A pump protection mode) 
c)   AUTO-STANDBY PUMP MODE (MUST BE PRE-ORDERED) 
d)   PUMPED OVERFLOW MODE (for systems with NO overflow from the tank. MUST BE PRE-ORDERED but 

ONLY if using a DIRECT SYSTEM as an extra solenoid valve is required) 

e)  HIGH LIFT PUMPS and the use of contactors (MUST BE PRE-ORDERED). 
f)  HIGH-FLOW BYPASS systems (MUST be pre-planned and understood). 
g)  UV SYSTEMS. These systems are outlined in this section but you should refer to the manufacturer’s data for 

specific details (MUST BE PRE-ORDERED). 

 
Very Important:  Whichever system you intend installing, there is a commissioning requirement to 
set-up the SYSTEM PRESSURE OPERATING POINT. This will be explained specifically in the 
instructions.  
 
NEVER LEAVE A SYSTEM POWERED UP WITHOUT CARRYING OUT THIS PROCEDURE.  
Failure to carry out this essential setting-up can result in non-operation, damage or excessive 
electricity consumption.  

 
For the purposes of this Instruction Manual, it is assumed that you have installed the Rain Water Holding 
Tank and Rainwater Filter in accordance with the instructions supplied with that product. 
To assist you in your work scheduling you should read the 

GENERAL

 notes below. Full details are given in 

the relevant sections, but it is worth noting these points 

IN ADVANCE.
