or connect the controller
communication cable yet
IMPORTANT NOTE
STEP 1
• Ensure the system plumbing comply
with the diagram provided here.
STEP 2
• Ensure the system wiring comply
with the diagram here. Make spacial
attention to sensor insertion on the
lower level of the tank and the
sensor must be fully in.
STEP 3
• Ensure you have filled the tank and
purged all the air by opening a tap
inside the house. The tank will be
purged when water runs freely
from the tap.
• Turn tap off.
• The cylinder has now been purged.
STEP 4
• Purge the circulating pump by
losening the brass 8mm nut on
the underside of the heat pump
untill water runs freely then
tighten again.
• The circulating pump has
now been purged.
STEP 5
Commission the controller
• select correct time of day
• select the desirable operational
mode (i.e. options 1-6)
• power up the controller and
connect the communication
cable to heat pump
STEP 6
• Initiate auto purge and system
start up.
• Ensure the system controller
is turned on and the time is
displayed.
• Ensure the heat pump isolator
is in the on position and power
is on to heat pump unit.
• On the controller, push and hold
the “menu” or “OK” button (i.e.
“menu” for V1 controller and “OK”
for V2 controller) until the word
“purge” is displayed and flashing
(approx 5 seconds).
• Now let go of the button.
• In about 4 seconds you should
hear the on-board circulating
pump come on.
SYSTEM STARTUP SEQUENCE
The system is now starting up and
will go through the following
sequence:
1The system will run a 5 minute
purge that pushes any air within
the heat pump unit into the tank.
Note the unit fan won’t be turning
at this point).
2After this 5 minute period the
pump will stop and the fan will
turn slowly. The system will not
be heating up until the until can
maintain a consistent 63°C (this
may take up to 4 minutes).
3The unit fan comes on properly
and the circulating pump starts to
circulate that constant 63°C water
through the tank.
Due to the smart top down heat
return system your customer
will have 50L of hot water within
20 minutes and a full tank in
about 3 hours.
After 15 minutes touch the heat
pump return connection to the
tank and ensure it is hot to touch,
if you feel good heat here you are
done and can comfortably leave
knowing you have completed
the install successfully.
HOW TO USE V1.1 OR V2

SECTION
The following system description section provides a brief overview of the the Air-Source
CO2 Hot Water Pump’s main components and functionality.
1.1 MAIN COMPONENTS
The system components of the air sourced heat pump that
customers will receive include:
Heat pump Unit, Storage Tank with PTRV, Controller, Heat
pump mounting legs.
1.2 SYSTEM OPERATION
The CO2 heat pump unit receives cold water from the
bottom of the tank. Using the heat from the ambient air
the heat pump heats the CO2 refrigerant to generate hot
water. The hot water returning from the heat pump unit
(fixed at 63°C) is injected into the top of the tank to provide
fast hot water recovery and excellent hot water stratification.
As this system delivers hot water exceeding 50 °C, a
tempering valve must be installed for delivery of hot water
to bathrooms. Untempered water may be delivered to
kitchen and laundry according to AU/NZS AS 3500
plumbing code.
The heat pump operation is controlled by an external
controller. The controller operates based on a sensor
connected to the tank at 55 – 69% level depending on tank
model i.d. The heat pump will be turned on if the
temperature at the sensor level on the tank drops below
59°C for the first cycle or 37°C for the second cycle in a
day and it will be run until the tank temperature at sensor
level reaches 59°C. The system controls are designed to
ensure that it meets the legionella requirements as
specified in the Australian standards. The heat pump will
run until the sensor level on the tank reaches 59°C. In the
subsequent heating cycles of every 24-hour period, the
heat pump “turn off” logic is adjustable by built-in timer
settings.
The default timer setting is programmed to run on
continuous operation but this can be adjusted by the
installer based on the home owner requirements to suit
their needs. More details regarding the controller
operation and settings is outlined in Section 2.
At ambient temperatures below 5.5°C, frosting may occur,
if this happens the heat pump will go into defrost mode in
order to protect the unit (i.e. this defrost functionality will
turn the heat pump on and will normally run for no more
than 15 minutes in duration). When the unit is in the
defrost function the pump and fan will stop and the
refrigerant heat will defrost the evaporator. As defrost
advances, the evaporator temperature will increase.
When a set temperature (preprogrammed) is achieved,
the defrost operation stops and the heat pump will operate
in line with its normal settings. More details regarding the
controller operation and settings is outlined in Section 6.
The “operational window” in this context refers to heat
pump “hot water production” mode which can be set by
using one of the options on the controller. From time to
time, especially during the winter and in very cold
climates, the heat pump operation may be disrupted or
extended by a built-in anti-freeze or defrost operational
mode. The defrost cycle can occur ONLY during the
operational window to defrost the ice build-up on the
evaporator at the back of the unit which is an air-CO2 heat
exchanger. The defrost cycle occurs when the ambient
temperature is less than about 5 °C. During the defrost
operation, the fan and pump stop, and the high-
temperature refrigerant which is originally used for hot
water production shall be supplied in order to melt frosts
on the evaporator (=air-CO2 heat exchanger).
The frost cycle can take about 5 minutes and this can
happen multiple times depending on the ambient
temperature, so in total, up to 20 minutes can be expected
for the entire defrost cycle. The heat pump also comes
with a built-in freeze protection cycle. Anti-freeze
operation can ONLY occur outside the operational window
of the heat pump and the purpose of the cycle is to protect
the water circuit (i.e. piping between tank and heat pump)
from water freezing. If the ambient and water pipe
temperatures drop below 3 °C, the heat pump will do the
anti-freeze operation. During the anti-freeze operation, the
heat pump works as a normal heating cycle so the fan and
pump should be running. The anti-freeze operation stops
when the water inlet temperature reaches 56 °C or
ambient temperature reaches 6 °C.

A licensed installer must adhere to occupational health
and safety guidelines and other relevant industry
associations. Under no circumstances should any installer
attempt to install a Reclaim Energy system without
reading and understanding this installation manual. For
any queries Reclaim Energy staff may be contacted on
1300 38 38 15.
Note that the Reclaim Energy system has been designed
to provide hot water for domestic applications only, other
applications such as space heating are not supported by
this product. Installing the unit for any other application
other than for domestic hot water application will void the
warranty. The installation guide for each major component
of the system as well as the whole system is covered in
this section.
The following sequence is recommended for installation:
1. Conduct site inspection
2. Identify heat pump and tank installation location
3. Plan system integration: Piping and fittings
4. Testing and commissioning
2.1 SITE INSPECTION AND
INSTALLATION PREPARATION
The very first step of installation is to find an appropriate
location for the installation of the heat pump unit that
includes: heat pump, tank, timer, and the controller.
It is recommended that:
• To reduce the heat loss from piping, the whole system
should be installed as close as possible to the main hot
water points in the house (kitchen and/or bathrooms).
• The maximum distance between controller/timer, tank,
and heat pump should not exceed 10 m. .
• It is recommended that the heat pump is installed on
the ground next to the tank.
• The heat pump unit MUST be installed outdoors,
the tank can be installed indoors.
• The back of heat pump unit draws in ambient ait
therefore it MUST NOT be covered. In order to have
sufficient air circulation behind the heat pump, the
minimum free space should be 0.15 m.
• The system requires at least two GPO power outlets
(one for controller, one for heat pump).
• The mounting surface of tank and heat pump MUST
be horizontal.
• The clearance on front and back of the unit are 350 mm
and 600 mm- please refer to Figure 2.
• The tank MUST be installed on a concrete slab on the
ground.
• Water supply quality must be in line with the
specifications of the heat pump unit and the storage
tank being installed.

• All tanks must be transported upright. Stacking is not
recommended for any tanks.
• Products should always be handled with care. Damage
incurred during the transportation is not covered under
product warranty.
2.1.3 UNPACKING OF THE COMPONENTS
• When unpacking, take care to ensure that the
components are not damaged in the process.
• Avoid using sharp blades or knives as this can scratch
the surfaces of the products.
Water quality is an important aspect that can influence the
systems operations and functionality. For the system to be
warranted the water used in the system must meet the
requirements outlined in Table 6 below.
If you have doubts regarding water quality please contact
your local water authority or have a water test completed.
In areas of poor water quality all major components will
have a reduced life due to the hardness of the water. In
areas with “hard water” (>200 mg/L or ppm), a water
softening device must be installed to ensure the long term
efficient operation of the system is met. Note that the
Reclaim Energy glass-lined tank has a sacrificial anode
to protect the vessel from corrosion. The glass line tank
warranty is linked to an anode inspection that must be
carried out every three (3) years.

• The storage tank must be installed at ground or floor
level and must stand vertically upright as per the
manufacturer guidelines.
• Tanks must be secured on a concrete or plastic
mounting slab as shown in Figure 1.
• The storage tank should be located as close as possible
to the most frequent draw off points in the building such
as the bathroom or kitchen. If the storage tank is
located a long way from hot water draw points, a hot
water circulation loop on a timer may be considered to
reduce the time-lag for water to reach the tap. Please
note this is not supplied by Reclaim Energy but the
installing plumber can consider installing a ring main
system for hot water circulation.
• The tank should not obstruct any windows, doors or
exits. Clearances must be provided to make servicing
and maintenance convenient without the need for
ladder or scaffold. For servicing, the PTRV must also be
easily accessible.
• The tank should be positioned to allow room for anode
removal.
• The storage tank must be installed in a properly drained
safe tray if installed indoors where leakage may cause
damage. The installation of the storage tank and safe
tray must comply with AS/NZS 3500.4 and all local
codes and regulatory authority requirements with
regards to its construction, installation and draining.
Tanks installed outside must be installed on a suitable
concrete slab.

After removing the right side piping cover of heat pump unit, the heat pump cold (inlet) and hot (outlet) pipes (connection
ports) will be accessible as shown in Figure 9.
The hot water outlet from the heat pump should be plumbed up to the top port on the tank (i.e., marked heat pump return
on the tank). The cold water inlet to the heat pump should be drawn from the bottom of tank port (i.e. marked heat pump
flow). The piping between heat pump and tank recommended to be as minimal as possible. There should be no valve such
as non return valve or strainer installed between heat pump and tank plumbing. The piping should have no restrictions. All
hot pipes including the PTRV must be fully insulated.

1 The maximum total distance between the
heat pump and tank should not exceed 10m
horizontal and 5m vertical.
2 The heat pump can be under or above the
level of tank for a distance up to 5m.
3 The maximum number of bends allowed is 4.
4 Do not put any restrictive valves such as check
valves or strainers in the heat pump flow/
return lines. This will void warranty and affect
the units performance
5 A 20 A isolator switch is recommended to
isolate the heat pump unit.
6 Sensors should be entirely pushed into the
tank and tight up to the gland.

2.3.6 SYSTEM WIRING
A licensed electrician should install the system with regards to the wiring diagram provided in Figure 10 and in
accordance with local/national wiring codes. The power cord chosen must be compliant with AS/NZS 3191 and the
nominal cross-sectional area should be 1.5 mm2or more.
It is notable that the heat pump must be installed on its own circuit (i.e. 20 A circuit)- AND hard wired to a 20 A ISOLATOR
SWITCH. The controller has its own plug and must be connected to a separate power point. The power point supplying the
controller can be fed from the heat pump circuit.

2.4 CONNECTING V1.1 OR V2 CONTROLLER TO THE HEAT PUMP
The communication protocol used in V2 controller is
different to that of V1.1. controller:
• If V1.1 controller is received, the RJ45 cable from
the controller should be wired up to the heat pump
• If V2 controller is received, the modbus cable should
be wired up to the heat pump
CONTROLLER KEY FUNCTIONS
Regardless of the version of controller received, the
installer must ensure the following:
1. The controller power cable is wired up to the
power point
2. The controller communication cable is correctly
wired up to the heat pump
a. RJ 45 cable for V1.1 controller
b. Modbus cable for V2 controller
3. With reference to the controller manual
a. The time of day is correctly selected on the controller
b. The operational mode is set per customer
requirement (i.e., default is option 1)
c. Applicable to V2 controller only: The Wi-Fi function
on the controller is enabled and end user
successfully connects the controller to the house
Wi-Fi and Reclaim Energy mobile app
4. The heat pump is purged by the controller during the
commissioning
a. Press and hold the “menu” or “OK” button on the
controller will initiate the 5-minute purge cycle.
5. Before installer leaves the site, he/she must ensure that
the heat pump receives signal from the controller and
the “heat up” process has been started (i.e., fan is
spinning, and hot water outlet pipes are hot and
reached +60°C). If time of day contradicts the option
settings (e.g., for example if the installer installs the
system at 10 am and the option selected is option 3), to
ensure the communications between heat pump and
controller is established, it is recommended to initiate
the heat up cycle by using the boost function.

connects to the
RJ45 terminal on
the PCB display
V2 controller
connects to
the modbus
terminal block
To wire up the modbus, the screws must
be opened and after the insertion of the
modbus crimp wire, the screws must be
completely tightened up.
