2. Introduction
Hydraloop Systems B.V. offers a range of patented residential greywater recycling products. Grey water from
the shower and bath is collected, cleaned and disinfected and reused for flushing the toilet, the washing
machine and garden. Optionally, approximately 50% of the washing machine water can be recycled through
the washing machine recycling option. The pipes need to be prepared in the house by isolating the drainpipes
of the showers/baths from the drainpipes of other water sources (such as sinks, kitchen and toilets). The toilet
fixtures and the washing machine have separate supply pipes for the water recycled by the Hydraloop unit
system (separated from potable water). Hydraloop H350/H300 is certified by IAPMO R&T against NSF/ANSI
350.
3. Product definition

5. Installation principle
The installation and commissioning of the Hydraloop unit can only be carried out by approved installers who
have been trained by Hydraloop Systems B.V. The image below shows an overview of the installation principle.
(Use this image for reference).
IMPORTANT:
As a source, you can use shower and bath water, and optionally water from washing machines, heat pumps
and air conditioning units. Washbasins, kitchen sinks and dishwashers may not be connected!

HL-20220107 Hydraloop Owner Manual

6. Startup time
The Hydraloop unit needs 21 days to develop the biological treatment process and to become fully operational.
The greywater treatment will start from the very first day, however this recycled water will be purged into the
sewer and backup water will be supplied instead of recycled water. After this start up period of 21 days, the
Hydraloop unit will automatically switch over to offer recycled water to the toilets, washing machine and/or
garden.
7. Period of 'non activity'
Hydraloop works complete automatic and adapts to the activity in the house. It is advised to always keep the
Hydraloop unit switched on and never disconnect the Hydraloop unit when leaving the house for some weeks
up to one month. If the Hydraloop unit does not detect any incoming or outgoing water flow for a period of 72
hours, it assumes there is no occupancy of the house and activates the purge valve to empty the lower recycled
water storage tank until 15 lit|3.5 gal is left in the storage tank. The upper processor treatment tank and the
upper collector tank will keep the minimum amount of water in standby mode and will continue to aerate this
water in intervals, so the treatment system is standby for the next incoming water. If the inactive period is longer
than 1 month the system will purge the upper processor tank as well and the system will go into ‘deep’ standby
mode. As soon as new incoming water enters the Hydraloop unit it will ‘wakeup’ immediately and starts working
again automatically. However, after a ‘deep’ standby mode the treatment system needs to be reactivated again,
just like at the initial startup at the installation of the Hydraloop unit. This will be done fully automatically by the
system itself.
8. Power cut
In case the electric power to the unit is cutoff, the Hydraloop unit will not supply water to the toilets and washing
machine until power is restored. However, the Hydraloop unit Electronic Control Unit (ECU) will continue to work
on its back-up batteries. If electric power is restored within one (1) hour, the Hydraloop unit will automatically
start working again as normal. Stored recycled water or backup water will be available immediately. In case the
power is not restored after more than one (1) hour, recycled water in the storage tank and all water in the upper
processor treatment tank will be purged to the sewer using the backup battery power. After power is restored,
the Hydraloop unit will automatically be fully operational again, supplying backup water until new recycled water
is available. If power cuts happen quite often in your area you could opt to install a low-cost Uninterrupted Power
Supply (UPS) to maintain power to the Hydraloop unit during a power cut.
9. System malfunction
The Hydraloop unit is reliable, and all critical components are monitored continuously by the unit itself and by
the Hydraloop unit server through the WiFi internet connection. In the unlikely event a component fails - for
example the UV lamp - the Hydraloop unit will automatically switch to its backup water, and everything in-house
will function as usual, but no recycled water will be distributed as a precaution. The visual alarm light on the
Hydraloop unit front plate will blink red 4 times per minute indicating an abnormal situation, a warning message
is sent via the WiFi connection to the Hydraloop unit monitoring server and to the customers Hydraloop App and
an audible beep as well will sound 4 times per minute. (See more about alarms in Chapter 10).
Warning: Hydraloop is designed for ‘normal usage’ and is not designed to receive solid materials like stones,
chemicals, paint residues, hair dye, bleach and disinfectants or any other matter that is unusual for shower/bath
and washing machine water. In the event these substances are entered into the Hydraloop unit, the system itself
can be damaged and the water treatment can be disturbed.
Note: Hydraloop Systems BV is not liable for any damage if the above or any other abnormal substances are
entered into the Hydraloop unit and the unit and/or the washing machine/laundry is therefore damaged.
10. Explanation visual alarm light and audible alarm
If one of the below mentioned alarms are activated, the Hydraloop unit will stop offering recycled water and will
offer backup water unless in case of Water distribution pump failure.
High water alarm: Audible alarm 2 beeps every minute, visual alarm 2 light pulses every minute

HL-20220107 Hydraloop Owner Manual

Air pump alarm: Audible alarm 3 beeps every minute, visual alarm 3 light pulses every minute
UV-C disinfection lamp alarm: Audible alarm 4 beeps every minute, visual alarm 4 light pulses every minute
Water circulation failure: Audible alarm 5 beeps every minute, visual alarm 5 light pulses every minute
Water distribution pump failure: Audible alarm 6 beeps every minute, visual alarm 6 light pulses every minute
In case of a water distribution pump failure, it can happen that water distribution to the users is blocked or limited
If you need assistance, call your Hydraloop dealer or contact Hydraloop technical support via email
[email protected] or phone on number: [phone] (EU) | [phone] (USA)
11. Maintenance
We recommend a check performed by a Hydraloop accredited installer once every two years.
This check contains the following elements:
- Descale the Hydraloop unit with a citric acid solution to descale the integrated water tanks.
- Remove, clean and descale the air diffuser.
- Replace the rubber membranes of the air pump every three years (according to the manual of the air
pump supplier).
- Replace the UV light bulb every two years by unscrewing the lid on the UV-C lamp housing.
- Effluent samples can be collected using the water valve that is connected to the washing machine.
In regions with very high levels of water hardness more frequent descaling of the water tanks may be
necessary. Please check water hardness during installation.
12. FAQs
HYDRALOOP WATER
What is greywater?
Greywater is lightly contaminated wastewater from bath and
shower, and optionally from washing machines,
hand basins, air conditioning units and heat pumps. It doesn’t include
wastewater from the kitchen or toilets, and it doesn’t contain
sewage (black water).
NOTE: handbasin water can only be used in Cascade set ups and cannot
be water from the kitchen.
What is Hydraloop water?
Hydraloop water is treated reusable water. It is clean, clear, safe, and
disinfected, ready for re-use.
Is Hydraloop water safe?
Yes. Hydraloop water is clean, clear and disinfected. The treatment
technology is NSF-350 certified and meets the most stringent
international standards. Hydraloop water should not be used for
drinking, cooking or personal hygiene.
Can I drink Hydraloop water?
The Hydraloop system is not meant for producing drinking water.
What can I use Hydraloop water for?
Hydraloop water is suitable for toilet flushing, washing machines,
garden irrigation and topping up swimming pools.
Can I use Hydraloop water in my shower, bath or
bidet?
No. There are standards in place that decide what one can use the
recycled water for. These differ per country. Generally, you are not
allowed to shower/bath with recycled water (although it would be
safe).
Can I use Hydraloop water in my kitchen?
No, Hydraloop water is non-potable water. Therefore, you should
not use it for preparing food or drinks, or for doing dishes.
Can I use Hydraloop water for my vegetable
garden?
Yes, you can use Hydraloop water for growing crops.
Can Hydraloop provide drinking water quality?
No, because it is not our core business. There are other companies that
offer products that can be added to turn it into drinking water. We do not
turn it into drinking water quality, because you only drink a few liters of
water.

HL-20220107 Hydraloop Owner Manual
10
Can I combine Hydraloop with a grease trap or
grease interceptor to recycle water from my
kitchen?
No, we do not allow it. Hydraloop is not designed and suitable to
recycle kitchen water.
1.The water from your kitchen sink and dishwasher is only a small
amount compared to the water from your shower and bath. The water
you save doesn’t weigh up to the costs of implementing a grease trap
or grease interceptor.
2. Even after passing a grease trap or grease interceptor, kitchen water
is still too dirty for water treatment in a Hydraloop system.
Can I combine Hydraloop with a rainwater tank?
Yes, you can. We have customers that use this combination and brought
down their tap water consumption from 150 liter per person per day to
15 liter per person per day.
You can connect Hydraloop with a rainwater system in two ways:
1. As a backup source for the Hydraloop system
(instead of tap water)
2. To transfer surplus recycled water into the
rainwater tank
Can I collect rainwater, and have it treated
by Hydraloop?
No, the tank size of each Hydraloop unit is designed for a daily input of
shower water. Rainwater comes in large volumes and storage capacity
of the Hydraloop tanks are not designed for these volumes.
Can Hydraloop replace a rainwater tank or reduce
its size and costs?
When you install a Hydraloop, you could size your rainwater tank just
for irrigation, because you use recycled Hydraloop water for toilet
flushing and the washing machine. You can recycle for example
75.000 liters / 21.000 gallons with H300 and 150.000 / 40.000 gallons
for H600 a per year.
If you recycle more water than you use inside the
building, Hydraloop can pump the surplus to a rainwater tank. This
way, you can use Hydraloop water to irrigate the garden and optimize
your usage of recycled water. You can also keep collecting rainwater in
a tank for garden irrigation.
We believe that rainwater should contribute to the hydrologic cycle and
not flow into the sewer. Using Hydraloop water inside and outside, and
using rainwater only outside is the most sustainable way to reuse
water.
Does Hydraloop work with water that contains a
lot of calcium?
Yes. If you have much calcium in your tap water, we
recommend descaling your Hydraloop every six months with 500
cl (1 pound) of citric acid. The app will advise you how
to descale your Hydraloop unit.
CERTIFICATION
Is Hydraloop certified?
Yes, Hydraloop is certified by NSF/ANSI according to the NSF-350
standard, PIA (Germany) and KIWA
SYSTEM
How does Hydraloop water treatment work?
Hydraloop uses a unique combination of sustainable water treatment
technologies that ensures the highest water quality, without requiring
regular maintenance or doing harm to the environment.
Hydraloop’s patented technology is consumer friendly, carefree and
sustainable. The treatment process removes hair, dirt, soap and other
pollution from greywater without the use of filters, membranes, or
chemicals, so no need to clean and exchange filters. This reduces the
operational costs substantial.
Hydraloop water treatment combines six technologies: sedimentation,
floatation, dissolved air floatation, foam fractionation, an aerobic
bioreactor, and disinfection of the treated water with powerful UV light.
How long does the treatment of the water take?
The treatment takes about 5 hours.
Does Hydraloop make a sound?
In standby mode and during water treatment, the Hydraloop units make a
sound of approximately 44 db. You can compare it with the sound of a
silent dishwasher. The sound comes from the dissolved air floatation
(bubbles) within the system. Another sound that is noticeable is when

HL-20220107 Hydraloop Owner Manual
11
the water pump is pumping, although this is only a brief moment and the
pump is a silent pump.
What happens if too much water enters the system?
The tanks will automatically overflow into the sewer.
What happens when all the Hydraloop water is
used up?
When you have used all of the Hydraloop treated water, the system
automatically switches to regular tap water. As soon as
new Hydraloop water is available, the system automatically starts to
supply this recycled water again.
What happens when I go away for a few days?
If no water comes in or leaves the Hydraloop for more 72 hours,
the Hydraloop system will automatically switch to ‘holiday mode’. If you
start using water again, the system automatically returns back into
operation.
What happens when I go away for a
longer period of time?
If you go away for more than 3 weeks, the Hydraloop will automatically
empty all the water from the tanks. The system will wait until you return
from holiday and automatically returns back into operation. Do not turn off
the Hydraloop unit! Power consumption will be neglectable.
What add-ons does Hydraloop offer?
- Third outlet for garden irrigation and/or topping up swimming pool
How many toilets can be connected
to a Hydraloop system?
A single Hydraloop H300 or H600 system can feed up to four (4) toilets at
a maximum distance of 20 meters wide and 12 meters high. Cascade
systems can be equipped with an external booster pump to extend the
range and number of toilets.
How many washing machines can be connected
to a Hydraloop system?
A Hydraloop system can be connected to one
(1) washing machine. The Hydraloop monitors the washing machine
program to supply recycled or fresh water. If more than one washing
machine is connected, this process would not work.
What is the warranty on a Hydraloop unit?
Static components (tanks) have a warranty of two years, all components
subject to wear and tear (valves, etc) have a warranty of one year.
We offer the Hydraloop Care option to extend the warranty on all
component for 5 years or longer. Hydraloop Care be extended for up to 20
years. Details are available up on request.
What is the lifespan of a Hydraloop unit?
The lifespan of a Hydraloop unit is at least 20 years.
BEFORE INSTALLATION
Does the Hydraloop system require extra
space?
A Hydraloop system requires 60 centimeters of space in front of the
system to enable easy access for service and maintenance.
Does the Hydraloop system require a wall
power outlet?
Yes. The wall power outlet must have earth safety protection and should
preferably be positioned above or next to the system.
What is the minimum weight the floor must be
able to carry?
Before you install the system, make sure the floor can carry a minimum
of 1000 kilograms per m2 (for the H300 system) or 800 kilograms (for
the H600 system).
INSTALLATION
Can Hydraloop be installed in an existing
building?
Yes. Hydraloop can be retrofitted to existing homes and apartments. But
you have to make sure the building is Recycle Ready. You can find
information on the preparation of your plumbing in the Factsheet “Have
your Building Recycle Ready”.
If you need to break walls to install a Hydraloop system, getting your
building Recycle Ready might become costly. The most economical way
is to combine the installation of a Hydraloop system with a
home or bathroom renovation.
Can Hydraloop be installed in a new building?
Yes. Hydraloop can be installed in any new building if the plumbing is
installed correctly. But you have to make sure the building is Recycle
Ready. You can find information on the preparation of your plumbing in
the Factsheet “Have your Building Recycle Ready”.
Can anyone install a Hydraloop?
Hydraloop is a high-tech product and can only be installed by an
accredited installer/plumber. Only this way we can offer our warranty.
Does the Hydraloop system require start-up
time before it’s operational?
Each Hydraloop system has a start-up time of 21 days. This is required
by the NSF-350 standard.

HL-20220107 Hydraloop Owner Manual
12
ONLINE CONNECTION
Why do you monitor Hydraloop systems in the central
server?
All operational Hydraloop systems are connected to the central server for
remote monitoring, remote service and over-the-air software updates.
Does the Hydraloop system have to be online
and connected to the central server at all
times?
In principle, yes. Your system needs to be connected to the central server.
There is no problem if your internet connection is not 100%
stable. Your Hydraloop system can function without server connection for
a limited amount of time (up to seven
days). You should, however, never turn the internet connection off.
What data does the central server monitor?
The central server monitors the status of the Hydraloop system
(operational, holiday mode etc.), as well as tank levels, valve positions,
pump settings and displaced water volumes over time.
How can you guarantee that the central server
is always online?
The Hydraloop central server runs at the premises of a qualified hosting
provider with secured data protection and back up services.
How does the data exchange between
my Hydraloop system and the central server
work? Are my data safe?
Your Hydraloop system has a secure TCP connection with the central
server. Your Hydraloop can only communicate with the central server if
the server sends a specific signal. Your Hydraloop cannot communicate
with other internet servers.
Can I change the WIFI network?
Yes, you can. Before you change the WIFI network, you should shut
down the old WIFI signal. Then please follow the steps as explained in the
installation manual.
What happens if my internet connection is
unstable or cut off?
Nothing happens, as long as the connection is restored within 7 days.
MAINTENANCE
How often does a Hydraloop unit need
maintenance?
One of Hydraloop’s benefits is that our systems don’t use filters or
membranes, so they can’t clog, and you never have to clean or replace a
filter. This reduces costs too. All Hydraloop units work fully automatic and
have a regular self-cleaning mode.
We recommend a preventive maintenance check by
your Hydraloop installer once every two years.
How often do I need to replace the UV lamp?
The expected lifetime of the UV lamp is 3 years. We recommend
scheduling a preventive maintenance check for your unit by
your Hydraloop installer every two years. During this check, the UV light
bulb is exchanged.
Do I need special cleaning products or laundry
detergents?
No, you don’t need to use special cleaning products or laundry detergents.
The only requirement is that you use products without bleach in your
bathroom cleaning products. (For all showers and baths that are
connected to the Hydraloop).
What happens if I clean the shower or bath
with a product that contains bleach?
If you clean your shower or bath with a product that contains bleach, you
need to restart the bioreactor with your smartphone app.
What happens if I dye my hair in the shower?
You can only rinse out hair dye in the shower after you’ve activated
the App to flush the dye rinse water directly to the sewer.
How do I restart the bioreactor?
In the app, select the ‘start-up procedure’. This will empty the tanks and
restart the bioreactor inside the Hydraloop unit. During the start-up
period, Hydraloop automatically switches to backup water. You can use
the showers and baths like you always do. When the biological
treatment is fully operational again Hydraloop will offer treated reusable
water again.
The ‘start-up procedure’ currently takes 21 days. Hydraloop will soon
offer a bioreactor vitalizer – in the form of a (re)starter kit – which will
shorten the start-up period to 7 days.
MODELS
What is the tank capacity of
a Hydraloop H300?
Each Hydraloop unit has two tanks. The upper tank, where the cleaning
process takes place, has a capacity of 180 liters (47 gallons). The lower
tank, where disinfected water is stored, has a capacity of 120 liters (31
gallons). Hydraloop H300 can treat 3 times the capacity of 180 liters per
day to a total of 540 liters.
What is the tank capacity of a Hydraloop H600?
Each Hydraloop unit has three tanks. The upper two tanks, where the
cleaning process takes place, has a capacity of 360 liters (95 gallons).
The lower tank, where disinfected water is stored, has a capacity of 240

HL-20220107 Hydraloop Owner Manual
13
liters (63 gallons). Hydraloop H600 can treat 3 times the capacity of 360
liters per day to a total of 1080 liters.
What is the difference between the H300, H600
and Hydraloop Cascade?
In short: the H300 has the ideal treatment capacity for a household of up
to 4 - 5 people (in Europe, where people on average use 45 liters | 12
gallons of water for showering).
The H600 has the ideal treatment capacity for small businesses and larger
households (and for households in countries where people on average use
90 liters | 24 gallons of water for showering).
The Cascade is scalable and made-to-measure, so it can handle projects
of any size.
For details, see the Product Factsheets for H300, H600 and Cascade.
What is the size of the models and how much
electricity do they use?
See factsheet H300, H600.
Hydraloop Cascade is a multiple of the number of Hydraloop units.
Size H300: W:34 cm (13.4 inch) x D: 80 cm (31.5inch) x H:185 cm (74 inch)
/ 6.1 foot)
Size H600: W:68 cm (26.8 inch) x D 80 cm (31.5 inch) x D: 185 cm (74 inch)
/ 6.1 foot)
Electricity: + 175 KWh/year (H300),
+ 350 KWh/year (H600)
SMARTPHONE APP
Can I decide what I want to use Hydraloop water for?
Yes, with the Hydraloop smartphone app you can decide how you want to
use Hydraloop water. In the default mode, Hydraloop primarily uses
recycled water for toilet flushing and for the washing machine. You may
prioritize irrigating your garden or topping up your pool (if you have these
add-ons to your Hydraloop unit).
The Hydraloop has just been installed, but my
smartphone app doesn’t show any available
recycled water. Why?
After installation, Hydraloop automatically enters the ‘start-up
procedure’. The biological treatment in the Hydraloop unit needs to
develop and will be ready in 21 days.
During the start-up procedure, Hydraloop automatically offers
backup water for your toilet, garden, and washing machine. After
that, Hydraloop will switch to recycled water and you can start monitoring
your water savings on the App.
13. Limitations
The maximum water temperature
Hydraloop can process is 140 degrees Fahrenheit/60 degrees Celsius. Using higher temperatures than 140
degrees Fahrenheit/60 degrees Celsius can damage the Hydraloop unit.
Hair dye entering the Hydraloop unit is not allowed. Doing so may damage the functioning of Hydraloop’s
biological treatment system and may also affect its seals. If this happens by accident, you have to set the
Hydraloop unit to back up water with the smartphone App and contact your installer. Hydraloop Systems B.V.
is not responsible for damage caused by products such as hair dye, paints or bleach to your laundry.
It is not allowed to use your shower and bath as a toilet. It is not a problem when some urine enters the unit by
accident and the water quality will be fine. However, this may only happen incidentally, not frequently.
Cleaning the shower and bath with aggressive cleaning products containing bleach is not allowed. Doing so
may damage the functioning of Hydraloop’s biological treatment system and may also affect its seals. If this
happens by accident, you have to set the Hydraloop unit to backup water with the smartphone App and
contact your installer. We recommend using environmentally friendly cleaning products. If using more regular
cleaning products, please check they do not contain bleach.
The operating temperature of Hydraloop is between a minimum temperature of 57 degrees Fahrenheit/14
degrees Celsius and a maximum temperature of 95 degrees Fahrenheit/35 degrees Celsius. The Hydraloop
unit must be protected from direct sunlight onto the Hydraloop unit itself.
