If the hot water system is not used for two weeks or more,
a quantity of highly flammable hydrogen gas may accumulate
in the water heater. To dissipate this gas safely, it is recom-
mended that a hot tap be turned on for several minutes or until
discharge of gas ceases. Use a sink, basin, or bath outlet, but
not a dishwasher, clothes washer, or other appliance. During
this procedure, there must be no smoking, open flame, or any
electrical appliance operating nearby. If hydrogen is discharged
through the tap, it will probably make an unusual sound as with
air escaping.

INSTALLATION OF THE HEAT PUMP
1. BASE
• The unit should be installed on a concrete plinth or stable structure
capable of sustaining weights in excess of 400kg. 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.
• When installed the 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.
• If property damage can occur due to water leakage, a safe tray
(overflow tray) must be installed.
2. AIR FLOW
• This unit is designed for external operation only and requires
a continuous supply of air to operate eciently.
• 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 (Diagram 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 unit must be installed a minimum of 150mm
o 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 unit 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.
⚠ WARNING

PLUMBING CONNECTIONS
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.
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 eciency 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.
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 at
the bottom of the heat pump. 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 the drainage pipe. 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.
PRESSURE & TEMPERATURE RELIEF TPR VALVE
• The system is supplied with a loose TPR valve appropriate to the
pressure rating of the water heater tank. If the TPR valve is not
present please contact your supplier. The valve Rated capacity:
850kPa;10kW; Set temperature: 93-99°C.
• The supplied TPR valve must be installed at Point 4 in section 3.2
DYNAMIC X8 Connection Dimensions and Components under
the socket marked "RELIEF VALVE".
• The TPR 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.
• 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.

OPERATING THE TPR VALVE
FREQUENCY: EVERY HALF YEAR  REPLACE IF REQUIRED
It is recommended to operate the TPR valve periodically to ensure
water flows freely. If water doesn't flow freely, the TPR valve will need
to be replaced.
• Locate the TPR valve on the left hand side of the unit.
• Carefully release the valve using the lever & release some water
from the tank.
NOTE: Water expelled may be extremely hot.
• If water flows freely the TPR appears to still be in a suitable
working condition.
• If water does not flow freely it would appear the TPR valve is due
for replacement.
• If the TPR valve needs replacing, please contact your plumber or
our service team for further assistance.
TEMPERING VALVE
• The 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.
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 diameter
no greater than that of the safety valve.
• Ensure the drain is sized to allow for water runo, even in incidents
where the safety valve has been fully opened.
• The drain outlet must always remain open to the atmosphere and
must not have a closing function.
• The ECV should be rated at no more than 700kPa.
PRESSURE REDUCING VALVE
• This water heater is supplied with a TPR 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 Connection
Dimensions and Components.
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 TPR valve
to form a duo valve.
ALLOWABLE MINMAX FILLING WATER PRESSURE
Allowable min-max filling water pressure: Min 200KPA - Max 750KPA
THE DEMANDED QUALITY OF WATER
• The bad quality water will produce more scale and sand, so this
kind of water should be filtered.
• The water quality should be analyzed before system running, to
measure the PH value, conductivity, Chloride ion concentration
and sulphate ion concentration.
• The acceptable water quality standard is showed as below table.
PH

Sulfate ion Silicon Iron content Sodium Ca
< 50ppm < 50ppm < 0.3ppm No requirement < 50ppm
• Suggest the filter meshes is about 40 meshes.
CHECKING THE ANODE & REPLACING IF REQUIRED
(Frequency: Every Half Year - Replace if required)
The anode protects the inner lining of your hot water tank. When
the anode become degraded the level of protection is diminished.
It is recommended that anode is periodically checked for its level of
degradation and gets replaced if required.
• Turn o the power and turn o the cold water inlet valve.
• Open a hot water tap and decrease the pressure of the inner
container.
• Open the drain port and exhaust the remaining water completely
in the release about 20L water.
• Remove the top cover by removing the locking screw and
rotating in a clockwise direction.
• Release the front casing, disconnect the display cable from the
electrical compartment and put aside.
• Locate the anode position on the left hand side.
• Remove the anode cover by releasing the two screws.
• Unscrew the anode and lift directly up.
• Check for degradation.
• If still in suitable condition, refit ensuring an eective seal
• If anode is in an unsuitable condition, replace with a new one,
ensuring an eective seal.

• Reopen the cold water inlet valve.
• Open a hot water tap until hot water flows out, then turn o the
hot water tap.
• Turn on the power to restart the unit.
• Now the unit can be used as normal.
CLEANING THE INNER TANK AND ELECTRIC HEATING ELEMENT
FREQUENCY: EVERY HALF YEAR
It is recommended to clean the inner tank and electric heating
element regularly to maintain ecient performance.
• Turn o the power.
• Close the cold water inlet valve & open a hot water tap.
• Use a flexible pipe to connect the drain port to a suitable sewage
drain. (Note: The min. heat resistance of the drain pipe must not
be less than 93°, if the drain pipe does not meet the requirement,
please open the cold water inlet valve & open a hot water tap,
until the temperature of the water is suitable for the drain pipe).
• Open the drain port of the water heater; drain out all the water
in the inner tank. If it is needed, use water to wash the inner tank
several times to clear the deposits.
• Close the drain port, re-fill the inner tank with water, and turn the
power back on.
⚠ FILLING THE SYSTEM:
• Once the system has been connected in accordance to Section
3.0 and 4.0 of this handbook, the tank can be filled and pressurised.
• 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 o.
• Always ensure the tank is completely full before connecting and
turning on the electricity supply.

OPERATION AND MAINTENANCE
1. Personals shall possess professional knowledge or operate
according to professionals from our company. To ensure the well
functioning, the system shall be checked and maintained after a
period of time. During the maintenance, please pay attention to
some points below:
• Control and protect the equipment, please do not adjust any
settings discretely.
• Pay close attention to whether all the operation parameters is
normal during system working.
• Examine regularly whether the electrical connection is loose,
if yes, fasten it on time.
• There will be calcium oxidized or other mineral substance
deposition on the surface of water heat ex-changer copper
coil after long period of operation, which will influence the heat
exchange performance and lead to high electrical consumption,
discharge pressure increasing and air suction pressure drop,
unit hot water volume produced is less. We can adopt formic acid,
citric acid, acetic acid or other organic acid to clean.
• The dirt retention on the surface of evaporator fin should be
blown by more than 0.6Mpa compressor air, brushed by fine
copper wire, or flushed by high pressurized water, usually one
time per month; if too much dirt, we can use paintbrush dipping
gasoline to clean.
• After long downtime, if we restart the equipment, we should make
following preparations: examine and clean the equipment carefully,
clean the water pipeline system, examine the water pump, and
fasten all the wire connections.
• Replacement parts must use our company original accessories,
can not be replaced by other similar accessories.
2. Refrigerant filling
Examine the refrigerant filling condition through reading the data
of liquid level from display screen, also the air suction and exhaust
pressure. If there is leakage or changing components of the refriger-
ation circulation system, we have to make air tightness examination
first.
3. Leak detection and air tightness experiment:
During leak detection and air tightness experiment, never let the
refrigeration system filling oxygen, ethane or other flammable
harmful gas, we can only adopt compressed air, fluoride or
refrigerant for such experiment.
4. To remove the compressor, please follow the following steps
• Turn o the power supply
• Exhaust the refrigerant from the low pressure end, attention
to reduce the exhaust speed, and avoid frozen oil leakage.
• Remove the compressor air suction and exhausting pipe.
• Remove the compressor power cables.
• Remove the compressor fixing screws.
• Remove the compressor.
5. Conduct regular maintenance according to the user manual
instruction, to make sure the unit running in good condition.
• Fire prevention: if there is a fire, please turn o the power switch
immediately, put out the fire using fire extinguisher.
• To prevent flammable gas: the unit working environment should
stay away from gasoline, ethyl alcohol and other flammable
materials, to avoid explosion accident.
• Malfunction: if malfunction occurs, should find out the reason,
eliminate it and then reboot the unit. Never boot the unit forcibly
if the malfunction has not been eliminated. If refrigerant leakage
or frozen liquid leakage, please turn o all the power switch, if
the unit can not stop buy controlling switch, please turn o the
general power switch.
• Never short connect the wire for protection required device, or
else, in case unit malfunction, it can not be protected normally
and will damage the unit.
