3.2 BASE
The following should be observed when selecting a base for a RAPID/X6:
• The unit should be installed on a concrete plinth or stable structure capable of sustaining weights
in excess of 315kg. The supporting structure must not shift over time (due to water drainage etc.).
A concrete base of at least 50mm thick or a well-seasoned hardwood slat at least 25mm is
required. If a concrete base paver is being used, a minimum dimension of 600mm x 600mm is
required.
• Please ensure that all four feet are supported by the base being used otherwise warranties may
be voided.
• Proper drainage should be observed for any overflow in accordance with AS/NZS 3500.2.
• When installed the Aquatech unit must be completely vertical and level as to ensure that
condensate can be properly drained. If the system is installed at a level with a tilt of more than
3 degrees, warranties may be voided.

3.3 AIR FLOW
• This unit is designed for external operation only and requires a continuous supply of air to
operate efficiently.
• Avoid installation in areas where falling debris such as leaves is prevalent, as this may result in
air vents being blocked or the unit being damaged.
• Avoid placing the system in locations with multiple walls or structures (See Figure 1 & 2). Always
maintain optimum perimeter from all structures.
• If installed under fixtures or home eves, there must be a minimum 300mm clearance between
the top of the unit, 600mm on the right-hand side of the system (when facing unit) and 150mm
on the left-hand side of the system (when facing system) (see section 2.3 AIR FLOW). The
Aquatech must be installed a minimum of 150mm off your home's wall so that the entire unit can
be accessed during any servicing work as well as to prevent circulation of cold air (see section
2.3 AIR FLOW). If the system cannot be properly serviced due to the system being installed
outside of these specifications, the owner will be liable for the associated plumbing costs of
draining and moving the system.
• The system should be installed so that the control interface is accessible to users and that there
is clear access to the electrical panel at the back of the system.
Where incorrect installation has occurred, warranties may be void or additional charges may be
required to ensure that the system is compliant and/or serviceable.

3.4 POWER SUPPLY TARRIFS
Electricity companies across the states and territories of Australia have different usage rates, naming
conventions and even available tariffs. Always be sure to check with your electricity provider that
the system is connected to a compatible tariff.
COMPATIBLE TARIFFS:
•
Continuous tariff
- 24 hours a day.
The Continuous tariff is what every household connected to the grid has as a minimum. If you
would like to utilize a Solar PV system to run your Aquatech system on, this is usually the only
tariff available to do so.
•
Shoulder tariff
- Min. 16 hours a day
The Shoulder tariff typically runs during the day and will turn off at night. The cost per kWh is
cheaper than a Continuous tariff. If your household has more than 4 people or are heavy users
of hot water, we recommend placing the Aquatech system on a Continuous tariff instead.
INCOMPATIBLE TARIFFS:
•
Off-Peak/Night time tariff
- Min. 8 hours a day
Aquatech systems are not compatible on Off-Peak/Night time tariffs.
Aquatech systems should not to be installed on an Off-Peak 8-10 hour supply tariff for the following
reasons:
• Aquatech heat pumps work up to 25% more efficiently during the daytime when ambient air
temperatures are at their highest. The cost of running the system is actually cheaper running on
a Shoulder tariff or Continuous tariff as the system will take considerably longer to heat on an
Off-Peak tariff.
• You may run out of hot water. If your system needs to heat twice a day, it will unlikely be able
to do some on an Off-Peak tariff.
• Servicing cannot be done outside business hours (the only hours an Off-Peak tariff has power).
If the system needs to be changed onto another tariff, the Aquatech owner will be liable for the
associated electrical costs.
If you would like further information regarding tariffs, we recommend speaking with your electrician
and energy service provider before your Aquatech is installed.
3.5 NOISE CONSIDERATIONS
All customers are recommend to set the system onto TIMER Mode to utilize the in-built timer function.
Setting the in-built timers to have the system run during the day is far more efficient and will also
limit any potential disturbances. The TIMER mode's factory setting limits system operating time
between 09:00-18:00, which is compliant with EPA prohibited operating hours.
Do not install less than 3 metres from a neighbour’s window or door (aside from garage
door or shed).
If you are experiencing noise issues with your Aquatech system, please contact
Aquatech directly. There are mean to mitigate the sound produced when the system is
operational.

5.0 PLUMBING INSTALLATION
5.1 PLUMBING CONNECTIONS
5.1.1 Cold water supply outlet
• The cold water supply connection is a G 3/4” female thread.
• The cold water supply should be connected to G 3/4” socket.
• The cold water supply outlet can also act as a drainage point for emptying the system.
5.1.2 Hot water connection
• The hot water supply connection is a G 3/4” female thread.
• The hot water supply should be connected to G 3/4” socket.
• To ensure thermal efficiency all hot water lines and connections must be insulated with a minimum
13mm closed cell insulation.
• All hot water supply parts must be constructed from copper. If using pipe of other material please
refer to local authorities for further instructions.
5.1.3 Condensate Drain
• The process of heat extraction from the atmosphere through
evaporator coils results in the production of water in the form
of condensation. More humid environments will produce
higher rates of condensation.
• To collect this water by-product a Condensate Tray is
located on top of the water storage tank. Overflow from this
tray runs out through the Condensate Drain.
• The system comes with a pre-installed condensate drain
connection elbow. Drainage of condensate from elbow to
nearest storm water to be done by the collection of
condensate into an open dish and drained via copper piping.
If not drained properly, the condensate line will attract
termites as well produce algae and moss growth.
• The Condensate line should be free of kinks and as the water
is gravity fed, should only be running down to ensure the free
flow of water.
Connecting any line to the condensate line without an air gap will void warranties.
A PVC tube is supplied which can be used to bridge the air gap between the
condensate elbow and dishes. The PVC tube can also be used to drain condensate
directly from condensate elbow to a storm water drainage point, if copper pipe
drainage is not required by local council regulations.!

!
11
5.1.4 Pressure & Temperature Relief (PTR) Valve
• The system is supplied with a loose PTR valve appropriate to the pressure rating of the water
heater tank. If the PTR valve is not present please contact your supplier. The valve Rated
capacity: 850kPa;10kW; Set temperature: 93-99°C.
• The supplied PTR valve must be installed at Point 4 in section 3.2 RAPID X6 Connection
Dimensions and Components under the socket marked "RELIEF VALVE".
• The PTR valve must be insulated with a minimum 13mm closed coupled insulation, to minimize
heat lost.
• The relief valve must be installed so that the drain line is facing downwards at all times with the
discharge point remaining open to the atmosphere.
5.1.5 Tempering Valve
• RAPID/X6 systems are automatically programmed to produce hot water in excess of 50°C. As
such, in accordance with AS/NZS3500, it is mandatory that a Tempering Valve is installed.
• We recommend a high performance or solar rated tempering valve is used to ensure a more
accurate hot water delivery temperature.
• Your old hot water system might not have had a tempering valve installed before and therefore
you will notice a change in the temperature of the hot water. This is normal and required under
new legislation. Should you have any concerns, please contact your installer.
5.1.6 Expansion Control Valve
• Please observe local requirements with regards to the installation of an ECV (optional in most
councils).
• When installing an ECV, ensure that the connecting pipe has a diameter no greater than that of
the safety valve.
• Ensure the drain is sized to allow for water runoff, even in incidents where the safety valve has
been fully opened.
• The drain outlet must remain open to the atmosphere at all times and must not have a closing
function.
• The ECV should be rated at no more than 700kPa.
5.1.7 Pressure Reducing Valve
• This water heater is supplied with a PTR valve rated at 850kPa and is designed for direct
connection to mains water supply with a pressure not exceeding this rating.
• Should main pressure fluctuate above this rating, a pressure limiting device (AS1357) should be
connected at Point 8 in section 3.2 RAPID X6 Connection Dimensions and Components.
A discharge pipe connected to the pressure relief device is to be installed in a
continuously downward direction and in a frost-free environment.
Do not connect any
pressure-relief device to the condensate drain pipe
. The water may drip from the
discharge pipe of the pressure-relief device. This pipe must be left open to the
atmosphere. The pressure-relief device is to be operated regularly to remove lime
deposits and to verify that it is not blocked.

!
12
5.1.8 Non-return/Isolating Valve
• It is compulsory that a non-returning/isolation valve is installed directly into the cold-water supply
line feeding the system. This will allow the hot water system to be isolated from the rest of the
homes water supply, making servicing, draining and replacing the unit easy. A hose-set must not
be used to connect the system to water supply.
• The non-return/isolation valve can be combined with a PRV valve to form a duo valve.
Filling the System:
• Once the Aquatech has been connected in accordance to Section 3.0 and 4.0 of
this handbook, the tank can be filled and pressurized.
• Open the non-return valve on the cold-water inlet to begin filling the system with
water. At the same time, ensure at least one hot water tap is open inside the
property. While the system begins filling with water you will hear air being expelled
from the open hot water tap. This is called "bleeding the system" and it ensures that
no air pockets remain. Once water begins running out of the hot water tap, the
system is completely bled and you can then turn the tap off.
• Always ensure that the tank is completely full before connecting and turning on the
electricity supply.
• When the system has been left running, but no hot water has been used for an
excessive period of time, it is recommended that hot water tap is left running for several
minutes to remove any potential gases through the plumbing network. Please do not
smoke or have naked flames present during this time.
