Installation steps #

– Important –

Ensure that you are following the plumbing and electrical regulations for your region and that your plumbing configuration is protected against backflow and cross connection to maintain the safety of the public water supply.

– Important –

The greywater inlet should be connected using the manual shut-off valve to be able to isolate the Hydraloop device.

Installation steps (more in-depth information below): 

1. Position the Hydraloop device in its planned location
2. Secure the Hydraloop from falling using the anti-fall straps
3. Remove the front plate
4. Connect the H300 wastewater outlet to sewer
5. Connect the incoming greywater to the inlet at the top of T1, via the inlet manifold
6. Connect the overhead bypass to sewer
7. Connect light and dark blue pressure tubes to inlet manifold. In downstream flow direction:
   1. Dark Blue
   2. Light Blue
      Resulting in the light blue pressure tube inserted closest to the Hydraloop inlet.
8. Connect the backup water supply using the provided hose, installing an isolation valve
9. Open the valve
10. Connect the recycled water outlets “WC”, “WM” and/or “AUX” to the dedicated recycled water lines using the flexible hoses provided
11. Plug the power cord into the wall socket and turn the power switch ON
12. Verification and Activation using the HDM (optional: with Hydraloop Sales Engineer)
13. Perform a cross-connection test protocol to ensure no cross-connections are present

Offloading and unpacking #

For stability, the Hydraloop device will be transported using a large footprint wooden pallet. The Hydraloop is wrapped in protective packaging. The Hydraloop is strapped to a small footprint pallet, which can be detached for easy internal transportation. Please take the following precautions:

• – WARNING –

  When moving the Hydraloop device, it is important to always keep it in an upright, vertical position. A horizontal position may cause damage to the devices’ internal components and seals.

• – Important –

  Leave the protective packaging on the device until it’s placed at its final installation position.

• When it is near its final position, remove the packaging and carefully place the device.

Large footprint to small footprint pallet:

To reduce the footprint of the pallet, take the following steps:

1. Unscrew all screws on both sides as indicated in image below, to remove the bottom beams from the main wooden plate.
2. Once the large footprint pallet is dismantled, leave the Hydraloop device strapped to the small footprint, transportation plate. It can then be easily moved with a 2-wheel trolley/dolly.

– WARNING –

Please do not remove the Hydraloop device from transportation plate until it has reached its final location. Do not use any apparatus underneath the device to move it as this will cause damage to the exposed distribution unit at the underside.  

Safety strap #

The H300 should be installed against a wall, leaving room for the electrical connection. The device should be secured to the wall to prevent it from falling over. The Hydraloop has two adjustable anti-fall straps. Adjust the bend plates according to its desired position. Then affix bend plates to the wall.

Front plate removal #

To remove the front plate, place a lever on the bottom of the front plate to carefully lift the plate upwards. The plate is being held in its position due to its shape. Once it moves upwards it will be free to remove forward. Disconnect the LED light connection from the front plate and put the plate aside.

Wastewater outlet installation #

The 40 mm | 1 1/2″ wastewater connection at the bottom of the Hydraloop needs to be connected to the sewer through the floor (Image XX (Option 1) or backwards into the wall (Image XX (Option 2).

We recommend a 110 mm drainage connection to connect into. During the weekly cleaning cycle of the Hydraloop T1 and T2 are being flushed at a volume of approx. 45 l/min. for the duration of approx. 1 – 2 minutes.

Inlet manifold assembly #

The inlet manifold come partly assembled. For the final assembly follow the steps written next to the image.

Inlet manifold connection: 2 versions #

Standard inlet manifold #

Follow the steps below for the proper installation of the inlet manifold.

Inlet manifold with inlet diverter #

 The H300 comes with the standard inlet manifold shown below. The inlet manifold comes preassembled and needs to be placed on site.

Other installation requirements for inlet #

1. Make sure to properly lubricate the black rubber rings on the AAV and inlet placement.
2. Always use the supplied 40 mm manual shut off valve to the Hydraloop inlet manifold.
3. Continue the grey water drain in the same diameter as an overflow pipe towards the sewage drain. The water line of the sewage drain needs to be at least 500 mm lower to prevent black water/sewage water to backflow into the Hydraloop.
4. Connect the light (semi-transparent) and dark blue pressure tubes to inlet manifold. In downstream flow direction:
   • Dark Blue
   • Light Blue
   • Resulting in the light blue pressure tube inserted closest to the Hydraloop inlet T1.

Overhead bypass to sewer #

When installing the grey water drain it is important not to restrict the internal diameter. Restricting the diameter downstream will negatively affect the functioning of the plumbing installation and the Hydraloop.

The Hydraloop inlet 40 mm. Create and overhead bypass according to the Recycle Ready Guide. Make sure the Y-junction that drops towards the Hydraloop is full bore, pointed down and in line with the flow to maximise the amount of water running into the Hydraloop.

After passing the Hydraloop inlet, connect the overhead bypass to the sewer connection. Make sure backflow of sewer water (i.e. black water) is made impossible. Backflow of sewer water will harm the functioning of the Hydraloop.

Recycled water outlets #

The Hydraloop device comes equipped with three standard outlet valves

1. “WC” dedicated for feeding multiple toilets (no high flush toilets)
   1. “WM” dedicated for feeding one (1) washing machine

“AUX” auxiliary outlet (e.g. irrigation)

– Important –

Note: the “AUX” outlet will be activated after order as add-on. This outlet is not permanently pressurized and only used when surplus water is available.

Connection specifications Hydraloop H300 & H600
Output connection		Size	Thread type
A	“AUX” Auxiliary outlet (optional)	½”	BSP male
B	“WC” Toilet outlet	½”	BSP male
C	“WM” Washing machine outlet	½”	BSP male
E	Drain to sewer outlet	40 mm / 1 ½”	Union clamp
Input connection		Size	Thread type
D	Backup water supply	½”	BSP male

(Optional) Greywater inlet via lift pump #

If the Hydraloop device is on the same or higher floor as the shower/bath or washing machine an external lift pump needs to be incorporated to pump greywater to the device. Ensure sufficient open-to-air ventilation from and to the lift pump and drainage fixtures. Always follow the lift pump manufacturers’ installation requirements.

Other lift pump considerations:

• Volume: Ensure the maximum volume of the lift pump holding tank is 50 litres. Larger volume tanks are known to negatively affect the grey water quality.
• Drain ventilation: Ensure open-to-air ventilation for the lift pump by installing a vent stack. Make sure the ventilation complies with local plumbing codes. If only a lift pump supplies the Hydraloop, the incoming gravity fed grey water drain into the Hydraloop also needs to be properly vented.
• Maximum flow: Choose a lift pump that has a maximum flow of 45 l/min or throttle the inlet flow.

Verification #

The Verification and activation of the Hydraloop device should only be carried out by approved installers who have prearranged their HDM login. This can only be done through messaging support@hydraloop.com. Once you have made your appointment you will receive authorization and your login.

1. Verification and Activation: This step is conducted through the HDM by an approved and trained Installer with a pre-requested login to the HDM. Hydraloop Sales Engineers will be available for first time installers to assist and guide them through the process.
2. Switch device from greywater bypass to the Hydraloop device
3. Go through testing of all device systems via the HDM “verification”Select priority options connected to toilets, washing machine, auxiliary outlet, and lift pumps
4. Activation of the H300 when all device systems have passed the validation steps. This will occur automatically once all HDM steps have been completed.

Testing for cross-connection using a dye test method #

– Important –

Testing for cross-connections shall be carried out directly after verification and before the greywater treatment system is in full operation.

Note: Experience has shown that biodegradable food colorants red and blue are suitably visible.

Control of the treated greywater distribution system: #

1. Close the backup water supply prior to testing.
2. Open all inline servicing valves of the recycled greywater lines.
3. Dose dye into storage tank for treated greywater (T3) and start pressure pump for the distribution.
4. Control all distribution points concerning the appearance of colored water:
   • Outlets for non-potable water showing colored water: PASS;
   • Outlets for potable water with colored or non-colored outflow: FAIL;
     • prohibited cross-connection between potable and non-potable water distribution system.

Control of cross-connections in the greywater harvesting system: #

1. Dosing of dye into all non-greywater harvesting points (e.g. toilet, kitchen sink)
   • No coloured water in the greywater treatment system: PASS;
   • Coloured water in the greywater treatment system: FAIL
     • wrongly connected collection points.

After testing the whole system shall be thoroughly flushed to remove all residual traces of colorant before it is commissioned and put into operation.

Startup time #

The Hydraloop device requires a minimum of 21 days (3 weeks) and 20 showers to develop the biological treatment process in the T2 tank and become fully operational. During this startup period the system will be in backup water mode. After this start-up period of 21 days (3 weeks) and 20 showers, the Hydraloop device will automatically switch over to deliver reusable water to the toilets, washing machine and/or auxiliary outlet.

Backup water and backflow prevention #

In the startup period and in case there is not enough reusable water available, the device will automatically switch to backup water. The device is connected to its backup water supply via a certified safe air gap to protect the backup water connection against backflow or cross contamination. Additionally, a non-return valve is mounted on the point of incoming backup water.

NOTE: If using rainwater as a backup water supply, pretreatment must be applied prior to entering the Hydraloop device. This treatment must be done according to EN 16941-1 or similar. Pretreatment should include at least a 5-micron filter and carbon filtration, UV disinfection, expansion vessel and a pressure regulator (depending on the booster pump). The incoming flowrate should be at least 12 lpm | 3.2 gpm, 1.5-3 bar | 21.75 – 43.5 psi.
