Shower Waste Water Heat Recovery System
IMPORTANT NOTE – Please Read
This picture guide is supplementary and does not replace the installation instruction manual supplied
with the Easyt+. Before starting installation please read all content provided with the Easyt+.
Before starting check section 3 of the installation instructions supplied with the Recoup Easyt+ for pre-installation
guidance on locating a suitable area for installation.
The Recoup Easyt+ needs to be installed horizontally under the bath or the shower tray. Installation should take
place on a at surface capable of supporting the WWHRS. The location should allow for access to all parts and allow
routine maintenance (E.g. Cleaning) to be carried out with relative ease.
The Recoup Easyt+ must be located within the heating envelope of the building.
The Easyt+ must be installed with consideration to the most recent ‘Approved document – Part H of the
Building Regulations’ for preventing the ingress of foul sewer gases.
Before starting the installation make sure you know which installation method is to be used. In a retrotted installation
System B is the most common and will be the method primarily shown here. The Easyt+ can also be installed with
the System A or System C installation method.
Use the images and instructions on the following pages to assist you with the installation process. Work down each
column following the numbered text below each corresponding image. An installation video can also be found on our
website to assist, www.recoupwwhrs.co.uk.

1. To retrot the Recoup Easyt+ below the shower system
installed must have a thermostatic mixer. This can be either
be deck mounted onto the bath or wall mounted above it.
2. To start retrotting the Recoup Easyt+ remove the bath
panel from the side of the bath along with any structure
supporting the panel that restricts access.
SETTING UP TO RETROFIT THE RECOUP EASYFIT+
5. If required remove part of the added support to allow access
during the installation.
6. Look at the water and waste pipe connections and identify
the waste water trap, the waste water out pipe, the hot water
pipe to the shower and the mains cold water pipe to the shower.
3. If the bath has a central foot installed this will need to be
removed to accommodate the Easyt+.
4. If a central supporting foot is removed, then alternative
raised support should be installed that will bridge over the
area where the Easyt+ needs to be positioned.
7. Disconnect the waste water trap from the bath along with
the waste water pipes to where they connect to the SVP
soil pipe.
8. Ensure that the mains cold water has been switched o󰀨 at
the stopcock then separate the pipe for the mains cold water
to the shower.

9. Connect a full ow shut o󰀨 valve (not supplied) and a double
check valve (not supplied) to the mains cold water pipe.
Ensure all xings are fully tightened and joints sealed.
10. Unbox the Recoup Easyt+. Included within the box is
the Easyt+ main unit, four height adjustable feet, the
installation documents and SAP identier label.
13. Position the Easyt+ under the bath.
14. Adjust the feet so that the end of the Easyt+ furthest from
the SVP soil connection is 30mm to 40mm higher than the
other end. This is so that the shower waste water ows
through the unit from one end to the other.
11. The Easyt+ incorporates symmetrical connections at
either end. Orientate the unit whichever way best suits for
the position of the mains cold water and waste water pipe
connections under the bath.
12. Screw the height adjustable feet into the threaded inserts
in the corners of the Easyt+ unit. Use the longer threads
on the higher edge of the Easyt+.
15. Ensure that the unit is horizontal at both ends perpendicular
to the ow of shower waste water.
16. Even packing under each adjustable foot may be required
if the waste water outlet at the lower end of the Easyt+ is
not higher than the connection to the soil pipe.

17. The ow of mains cold to preheated water needs to run
in the opposite direction to the ow of the shower waste
water.
18. Connect a female half inch BSP connector (not supplied)
to the half inch BSP male connection at the lower end of
the Easyt+ unit.
21. Connect a second female half inch BSP connector (not
supplied) to the half inch male connection for the preheated
water at the higher end of the Easyt+.
22. Connect a full ow shut o󰀨 valve (not supplied) to assist
with easy removal and maintenance.
19. Connect the opposite end of the female half inch BSP
connector to the double check valve and full ow shut o󰀨
valve previously connected to the mains cold water.
20. Ensure all xings are fully tightened and joints sealed.
23. Connect the preheated water output to what was the mains
cold water connection on the showers thermostatic mixer.
24. Ensure all xings are fully tightened and joints sealed.

25. This setup creates the system B installation method
supplying preheated water to the shower only. For system
A installations a T joint would be required to also send the
preheated water to the water heater.
26. Using 40mm push t, or 43mm solvent weld pipe, connect
the warm shower water in to the bath shower trap. The
warm shower water in is the highest end of the Easyt+.
29. Ensure the cold mains water is turned back on at the
stopcock. Open the full ow shut o󰀨 valve on the mains
cold water feed to start the cold water ow into the Easyt+.
30. Open the full ow shut o󰀨 valve on the preheated water pipe
to start the ow from the Easyt+
27. When the highest point is at the opposite end to bath trap
the pipes can be run above the lower prole section of the
Easyt+.
28. Using 40mm push t or 43mm solvent weld pipe, connect
the waste water out at the lower end of the Easyt+ unit
to the SVP soil pipe. Ensure all xings are fully tightened
and sealed.
31. Replace any bath supports removed to allow access to
install the Recoup Easyt+
32. Replace the bath panel and any supporting structure.

33. Please check and complete the following important points:
a) Ensure the preheated water supply is only feeding the DHW water heater and the
cold water inlet of the shower’s thermostatic mixing valve (System A), the cold inlet
of the shower’s thermostatic mixing valve only (System B) or the water heater only
(System C).
b) The preheated water supply from the RECOUP Easyt+ is clearly labelled to avoid
future connections of other services. Preheat supply tape is available for this.
c) Pipework between the RECOUP Easyt+ and the water heater and/or cold
water inlet of the thermostatic mixing valve is insulated.
d) When the complete system is being checked and pressure tested, the
RECOUP Easyt+ must be isolated if the system testing is to proceed above
10 bar.
e) Ensure the SAP label supplied correctly identies the System installed and is
applied near to the water heater in the property (Part 3).
f) Complete the design and installation checklist or register the installation.

Maintenance
The maintenance required for the RECOUP Easyt+ is very minimal, however, it is recommended to clean the unit
periodically to avoid any reduction in e󰀩ciency. This cleaning will remove any build-up of soap and dirt residue on the
outside of the copper pipe where the waste water passes.
The following maintenance procedure is suggested:
A hair ltering device as part of the bath / shower trap is recommended to reduce the amount of hair that gets into
the RECOUP Easyt+.
Every 2 months, use 1-2 litres of hot water up to 70°C (re-use waste water from boiling potatoes or pasta to save
energy) and apply into the bath / shower-tray drain in 2 stages, with around 5 minutes between. (This will help
dissolve soap residues on the copper pipes in the RECOUP Easyt+). Use the shower shortly after to make sure
any debris is ushed away. It is possible to use chemical agents sold for declogging as a cleaning agent if required.
If no maintenance is carried out, the RECOUP Easyt+ will work, but the e󰀩ciency may decrease over time.
Warranty
The RECOUP Easyt+ comes with a 2 year warranty unless agreed otherwise. This starts from either
the date of invoice from Recoup Energy Solutions Ltd or the date of installation recorded on the received
SAP documentation in line with the SAP Design and Installation Checklist.
This warranty is conditional on the product being installed in accordance with these instructions (Installation
and ALL requirements for SAP, if product is to be recognised for Energy e󰀩ciency calculations), correct
plumbing practices and Building Regulations.
