Presentation of the product
How it works
The heat pump water heater uses unheated air to prepare domestic hot water.
Heat energy extracted from the ambient air is absorbed by the refrigerant through heat transfer at the
Evaporator. This energy is concentrated by the Compressor and then transferred by the Condenser into
the hot water tank. This cycle is repeated after the refrigerant has cooled. A low energy fan ensures
ambient air movement across the Evaporator.
The air is propelled through the appliance
by a fan, which ventilates the various parts,
including the evaporator.
As it passes through the evaporator, the
coolant evaporates and absorbs calories
from the incoming air.
The compressor compresses the coolant,
thereby increasing its temperature.
This heat is transferred to the domestic
water in the tank by the condenser.
The coolant expands in the thermostatic
expansion valve and cools down. It is then
ready to absorb heat again in the
evaporator.
The colder the air, the more difficult it is to extract the calories. Similarly, the higher the hot water setting,
the more difficult it is for the heat pump to transfer the extracted calories.

Possible consequences
- The negative pressure in the
room due to the expulsion of
the exterior air may result in air
entering through the doors and
windows. Provide an air inlet
(same diameter as the ducts)
from the exterior in order to
avoid sucking air from the
heated space.
- Caution: in winter, the air will
be colder than the air expelled
by the water heater, resulting
in a drop in temperature in the
garage.
* In warmer climates ducts may be reversed to provide cold air into an adjacent room for cooling. Connect
(air in) from outside and (air out) into the adjacent room. NOTE: It is not recommended to reverse ducts
(air out) into the room that the HPWH is installed. This will reduce the COP and increase the cooling of the
room.
Unsuitable configurations
Prohibited Ducting installation
configurations
The water heater draws in air
from a room containing a
charged source of heat used to
heat the room.
Connection to mechanical
ventilation
Connection to the roof space
Uses heat energy from a higher cost source.
The greasy vapour and dust that may flow through the ducts of the
mechanical ventilation system can reduce the life time of your water
heater.
If the insulation between the ceiling and the roof space is insufficient,
this installation may result in heat loss from the house. In extreme
cases, condensation may appear on the ceiling of the rooms beneath
the cooled parts of the roof space.
Risk of falling objects and aspiration of dust by the raised water heater
in this configuration, that can reduce the life time of your water heater.

3- Take the water heater off the pallet and place it by the hydraulic connection.
+/- 1°
MAXIMUM!
The water heater must be installed on a smooth and horizontal
floor.
If this is not the case, it must be levelled using the supporting feet.
If this precaution is not taken, problems may occur evacuating the
condensates, resulting in frosting.
In accordance with AS/NZS
60335.2.21 the water heaters
must be fixed to the ground
using the attachment provided
and in compliance with the New
Zealand Building Code Clause
G12, Seismic restraint of
storage water heaters.
The clearance required needs to be adequate for service/re placement of cold water inlet piping devices,
PTR valve and tempering valves (where fitted), elements and thermostats. This may be facilitated by
correct orientation of the cover positions when installing. There are no operational clearance limitations to
surrounding structure. PTR valve removal requires approximately 150 mm for withdrawal.
AS/NZS 3500.4 – National plumbing & drainage. Hot Water Supply Systems – Acceptable solutions.
Combustible Material :
It is recommended to not place combustible material on or adjacent to the water heater.
Internal Installation Safe Tray :
For internal (inside home) installations, a safe tray is recommended in accordance with AS/NZS 3500.4.
Hydraulic connection
Cold water inlet
Before making the hydraulic connection, it is essential to clean the feed pipes thoroughly to avoid the risk
of metal or other particles entering the tank or the water heater.
Cold water piping should be provided with a 500 – 560 kPa Pressure Limiting Valve at the point of cold
water connection to the water heater. In addition to the Pressure Limiting Valve, it is a requirement of AS
3500.4 & NZBC G12 that both a Stop Valve and a Non Return Valve are installed upstream of the Product.
No parts (stop valve, pressure reducer, etc.) must be placed between the pressure limiting
valve and the cold water inlet of the water heater, apart from a copper pipe.
Note: since limited water discharge from pressure limiting valve is normal in the heating operation, the
discharge pipe needs be connected to external drain.
- 9 -
Hot water outlet
(
)
Do not connect the hot water inlet directly to the copper pipes in order to avoid iron/copper galvanic
couples (risk of corrosion). The hot water inlet (item 10 on page 5) must be fitted with a dielectric coupling
(supplied with the appliance).
If corrosion occurs on a hot water inlet that is not fitted with this protective device, our warranty does not
apply.
Where a maximum hot water delivery temperature is specified by Local, State or Federal
Regulations, a Tempering Valve shall be installed at the Hot Water Outlet, as required.
The included specified Pressure & Temperature Relief Valve must be installed as shown in the
schematic. The PTR valve should be connected to a drain point to accommodate discharge as a
result of both water expansion during heating, and also pressure fluctuations.
A discharge pipe connected to the pressure relief valve is to be installed in a continuously
downward direction and in a frost- free environment.
WARNING: The Pressure Temperature Relief valve and drain line must not be sealed or blocked.
Evacuation of condensate
Air passing through the Evaporator may result in some condensation. If the humidity of the
location Warrants, it may be preferable to connect a simple polymer hose from the Condensate
Drain (Item 16), to the convenient PTR drain point.
Depending on the humidity of the air, up to 0.25l/h of condensate may form.

Air connections.
Your heat pump water heater can be fitted with ducting accessories that are not supplied with the water
heater.
If the volume of the room in which the thermodynamic water heater is installed is insufficient, it can be
connected to 160 diameter
during operation. Therefore, it is essential to choose insulated air ducts.
Poor ducting (crushed ducts, ducts that are too short or too many corners, etc.) may have a negative
impact on performance. Therefore, you are strongly advised to use rigid ducts.
When connected to ducts, the regulation must be adjusted accordingly (see Setting the
regulation section, page 15).
The total head loss in the ducts and accessories of the air inlet and outlet must not exceed
150 Pa. The head losses must be calculated using the measuring tools supplied by the
manufacturer and on the basis of the proposed ducting accessories.

ECO mode
This mode uses the heat pump only to produce hot water. Under certain conditions, this mode may
result in shortages of hot water (mainly due to air temperatures outside the operating range).
BOOST mode
BOOST mode can be used to force the heat pump and the electric backup to work at the same time in the
event of high demand.
The regulation automatically returns to the previous mode at the end of the cycle.
ABSENCE mode
This mode helps to protect the tank when the user is absent. The tank is protected against corrosion and
the regulation heats the water to above 7°C. Use the arrows to select the number of days during which you
will be absent. The length of the absence can be set to between 1 and 99 days. If a number of days is not
selected, the water heater remains in ABSENCE mode permanently.
On the last day of the period of absence, the water heater performs a cycle to avoid Legionella. The
regulation automatically returns to the previous mode at the end of the ABSENCE mode.
INFO mode
In this mode, it is possible to view the temperatures measured by the various sensors, the maximum and
minimum values measured and the time for which the heat pump or the electric backup has been working.
Values can be reset by pressing
+ at the same time.
Automatic defrost
The water heater is fitted with a defrost function. In negative temperatures, the water heater is
automatically defrosted by opening a solenoid, which sends the hot gas from the compressor directly to the
evaporator, where the frost melts. In positive temperatures, only the fan is used to defrost the heat
exchanger.
The defrost mode is activated by the temperature sensor in the evaporator. This temperature sensor can
detect the formation of frost, irrespective of the air temperature or the configuration of the system.
The defrost cycle lasts a maximum of 15 minutes.
Fan controls
When FAN is set to 0 (FAN 0), the water heater draws the air in from the room. The fan permanently works
at low speed in order to reduce the noise level, while producing a sufficient volume of hot water. Do not
use ducts and the FAN 0 setting at the same time.
The FAN 1 setting is used when a single duct is installed, usually on the air outlet. This configuration
evacuates the cold and dry air from the room.
The FAN 2 setting is used when exterior ducts are installed on the air inlet and outlet.
In the positions FAN 1 or FAN2, the fan operates at high speed to compensate for the head loss caused by
the ducts.
In the positions FAN 0 or FAN 1, the lower limit for operation with the heat pump is an air temperature of
3°C, in order to prevent the water heater from freezing (-5°C in FAN 2).

Recommendations – Maintenance & Repairs
Advice for users
Flushing of sediment and draining :
To flush or to drain the water heater, power must be turned off and then turn off the cold water supply to
the water heater. The lever on the pressure and temperature relief valve should be opened but care
should be taken so the lever does not snap back as it could damage the valve seat. The pressure in the
water heater will be released when the lever is opened. The union at the cold water inlet to the water
heater should be undone and a hose should be attached to the water heater side of the union. The other
end of the hose should go to a drain.
Opening the pressure and temperature relief valve allows air into the water heater and for the water to
drain. Following complete draining of the water heater, the closest hot water taps may be opened fully
and the pressure and temperature relief valve closed with care. Following reconnection at the cold water
inlet, the cold water stop valve is now opened fully and the water heater may be filled with cold water
and flushed through to ensure the cylinder contains no sediment and is clean. Finally the closest hot
taps are closed and power may be turned on again to the completely filled water heater.
In the event of an anomaly - the heater does not heat or steam is released from the Pressure Temperature
Relief valve - switch off the electric power supply and contact your reseller.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety.
Domestic maintenance
Water heaters do not require much domestic maintenance by the user. Operate the Pressure Temperature
Relief valve once or twice a month to eliminate any residue of scaling and check that it is not blocked.
Regularly check the display for alarms. If an alarm appears, refer to the Troubleshooting section, page 22).
DANGER: Failure to operate the Pr essure Temper ature Re lief valve easing gear at least once every six months
may mask a problem with the water heater. Continuous leakage of water from the Pressure Temperature Relief
valve may indicate a problem with the water heater.
It is not unusual for the Pressure Temperature Relief valve to allow a small quantity of water to escape during
the heating cycle and this must be left open to the atmosphere.

Maintenance by a qualified professional
To protect the performance of your appliance for many years to come, it must be checked by a
professional every 2 years.
Switch off the electric power supply (circuit breaker, fuses, etc.).
Drain the tank:
close the cold water inlet (isolating valve),
open a hot water tap,
set the safety valve to the drain position.
Remove the front cover.
Disconnect the wires from the terminals of the thermostat.
Remove the heating assembly.
Remove any scaling that is deposited in the shape of sludge or a film on the floor of the tank and
thoroughly clean the ducts of the heating elements and the thermostat. Do not scratch or strike the scaling
on the walls, or you might damage the coating. Any residue can be removed using a water and dust
vacuum cleaner.
Clean the interior of the sheath to remove any scaling.
The anti-corrosion anode is made of titanium and does not need to be inspected or replaced.
Install the heating assembly with a new seal. Tighten the nuts gradually to a reasonable torque. Alternately
tighten nuts that are opposite one another.
Fill the water heater, with a hot water tap open. When the water reaches the hot water tap, the tank is full.
Check the seal for leaks and then install the thermostat and its support and connect the electric power
supply.
On the following day, check the seal again for leaks and slightly tighten the bolts, if necessary.
Check the electric connections.
Check that the temperature sensor is properly positioned in the pocket near the electric backup. The
sensor must be fully inserted in the pocket.
Evaporator:
Check that the evaporator and the fan are clean once a year. If these parts are soiled, the performance of
the heat pump will be diminished.
To access the evaporator, remove the cover by unclipping it with a screwdriver. The left half-shell can also
be removed in cases of difficult acce ss.
If necessary, clean the evaporator and the fan with a soft brush. Brush the evaporator very carefully to avoid
damaging the vanes. If the vanes are folded, straighten them using a suitable comb.
Always switch off the appliance before opening the front cover or the top cover
Expansion valve:
Only personnel specialised in refrigerating systems can access the adjusting screw of the expansion valve.
Adjusting the expansion valve without the manufacturer's approval may result in the product warranty being
cancelled.
In general, you are advised not to touch the settings of the expansion valve without having first tried all the
other repair solutions.
Condensate evacuation tube
Check that the condensate evacuation tube (item 12 on page 5) is clean. Local pollution by dust can result
in deposits in the condensate catch tray. These deposits may block the condensate evacuation tube,
resulting in the excessive accumulation of water in the tray, which can cause malfunctions.

12. If the system is either sold and/or repaired or altered by any third party without the consent of Atlantic
Australasia Pty Ltd.
13. Exclusions due to Water Composition
Please take note :
Water composition varies widely in Australia and New Zealand. In order to ensure a long and trouble free life the
Atlantic Heat Pump Water Heater incorporates an impressed current protection system, normally only found in
major installations in contact with water such as gas transmission pipelines. It is important that the composition
of water is not excessively high in salt which may result is aggressive attack, or calcium carbonate (also known
as water hardness) which will coat and isolate the effectiveness of the impressed current anode. Warranty is
therefore excluded where water composition in the hpwh exceeds the following :
Total dissolved solids 1000 mg/litre or p.p.m.
Electrical Conductivity 1400 uS/cm.
Total hardness 200 mg/litre or p.p.m.
Chloride 250 mg/litre or p.p.m.
Sulphate 250 mg/litre or p.p.m.
Magnesium 10 mg/litre or p.p.m.
Sodium 150 mg/litre or p.p.m.
pH Min 6.5 and Max 8.5
Water from springs, bores and dams is also excluded from meeting Warranty conditions because of the rapidly
variable composition of these waters due to groundwater salinity and aggressive mineralisation. Water MUST be
from a supplied, reticulated source or from rainwater to ensure Warranty compli ance.
