NaturalFlow Series NF1500 Pump Installation Instructions 

 

The NaturalFlow system is to be installed or signed off by a registered Drain layer to the design specified by 
Waterflow NZ Ltd. 

The following installation instructions and procedures followed correctly will ensure System  performance is 
not compromised in any way. 

1.

 

Excavate a 1.4m (wide)  x 1.6m (long) level platform for Wormorator® at the  appropriate depth, so 
when it is placed there is adequate fall to inlet from its source. 

 

2.

 

Excavate a 1.4m (wide) x 1.6m (long) level platform, below the Wormorator® platform, for the Dose 
Chamber and placed so that the Dose Chamber is centered to Wormorator®. 

 

3.

 

Lay 100mm of bedding metal on platforms and place Wormorator® then Dose Chamber. 

 

4.

 

Fit the short length of DWV50 supplied, in outlet hole, in base of Wormorator®. 

 

5.

 

Analyze where Black Water is to enter Dose Chamber and mark center of UNISEAL® @ 790mm high 
from base of Chamber. Very carefully drill a 62.7mm hole with a  hole saw at marked center and fit 
50mm Uniseal (see Uniseal instruction details appendix B below) 

 

6.

 

Apply some lubrication to the UNISEAL® and carefully connect Wormorator® and Dose Chamber with 
DWV50, fitted to Wormorator®. (see UNISEAL® instructions appendix B) N.B. pipe to protrude 50mm 
through UNISEAL® 

 

7.

 

Where possible excavate a trench away from System and lay drain coil and drainage metal at the base 
of the system to drain away any surface or ground water. On a flat or high water table site System must 
be bedded in as per appendix A below 

 

8.

 

Analyze where Grey Water is to enter Dose Chamber and mark center of UNISEAL® @ 550mm high 
from base of Chamber. Very  carefully drill a 127mm hole with a  hole saw  at marked center and fit 
Uniseal (see Uniseal instruction details appendix B below) 

 

9.

 

Connect Grey Water from source to Dose Chamber 

 

10.

 

Take a minimum of 2 photos at this point to show correct installation. 

 

11.

 

Back fill around tanks with pea metal. DO NOT back fill with soil or clay of any type as this can cause 
point pressure on the modules and could cause distortion. 

 

12.

 

Connect pump with fittings supplied and lay feed line to disposal field. 

Caution: System must be protected from excessive super imposed loads both lateral and top loads. E.g. loads 
from vehicular traffic. There needs to be at least 2m of clearance maintained around system. 

Worms: Ensure adequate moisture in the Wormorator® and add worms once installed unless systems is not 
going to be used within 2 months of installation.
