Mandatory installation of a safety device in a frost free location (or
any other new device which limits the tank pressure) to 850 kPa
according to the nominal pressure, with a size of 3/4’’ on the input
of the water heater, respecting the local regulations .
Operate regularly the discharge of safety device to prevent scaling and
check that it is not blocked.
To drain the device switch o the power and the supply of cold water,
open the hot water faucets and manipulate the safety valve.
The pipes used must support 1 MPa (10 bar) and 100°C.
Cold Water Inlet
Cold water piping should be provided with a 350 – 500 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.
Hot Water Outlet
Where a maximum hot water delivery temperature is specied by local,
state or federal regulations, a tempering valve shall be installed at
the hot water outlet, as required.
The included specied 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

6
result of both water expansion during heating and also pressure
uctuations.
The supplied PTR valve must be tted with Teon tape. Do not use paste
or hemp.

DN15 copper drain lines must be connected to the discharge pipe of the
PTR valve. The copper drain line must fall away from the ESWH and
be installed in a frost- free environment.
The termination point of a drain line must comply with the requirements
of AS/NZS 3500.4

WARNING: The Pressure Temperature Relief valve and drain line must
not be sealed or blocked.
Electric Connection
All electrical work must be carried out by a registered electrician and in
accordance with AS/NZ 3000.
The Atlantic ESWH must be lled with water before connection to a
power supply.
Switch o the power before removing the cover to avoid any risk of injury
or electric shock.
The installation must be equipped, upstream of the appliance, with
a bipolar cut-out device (fuse, breaker switch) respecting local
regulations (30 mA earth-leakage breaker).
Always connect the earth conductor of the cable to the earth ground
wire or connect the earth conductor to the appropriate terminal
identied by the symbol.

7
Thermal cut-out
All Atlantic ESWH are equipped with a thermal cut-out with manual
resetting which shuts o the power to the water heater if it
becomes overheated.
If the circuit breaker keeps tripping,
a) Switch o the power before taking any further action,
b) Remove the cover,
c) Check the electrical connections,
If the cut-out continues to trip, replace the thermostat. Never by-pass the
safety device or the thermostat. Connect the power supply only via
the terminal.
The thermal cut-out tted to the auxiliary electric heating element must
be replaced by an authorized agent. Failure to respect this clause
invalidates the warranty.
DANGER: The operation of the thermal cut-out indicates a possibly
dangerous situation. Do not reset the thermal cut-out until the
water heater has been serviced by a qualied person.

Flushing of sediment and draining
To ush or to drain the water heater, power must be turned o and then
turn o 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
lled with cold water and ushed 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 lled
water heater.
In the event of an anomaly - the heater does not heat or steam is
released from the Pressure Temperature Relief valve - switch o
the electric power supply and contact your reseller.
Domestic maintenance

Water heaters do not require much domestic maintenance by the user.
Operate the Pressure Temperature Relief valve once a month to
eliminate any residue of scaling and check that it is not blocked.
Open and close the PTR valve slowly to avoid damage to the seal.

DANGER: Failure to operate the Pressure Temperature Relief valve
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.

9
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.

Installation
In accordance with AS/NZS 60335.2.21 the water heaters must be xed to
the ground using the attachment provided and in compliance with
the New Zealand Building Code Clause G12, Seismic restraint of
storage water heaters.
Installation must also comply to AS/NZS 3500.4.2 and all local codes.
The clearance required needs to be adequate for service/replacement
of cold water inlet piping devices, PTR valve and tempering valves
(where tted), 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.

The oor has to support a load of 400 kg minimum (surface below the
water. The selected place of installation has to conform to the
protection level IP X1B.
Combustible Material
It is recommended to not place combustible material on or adjacent to
the water heater.

Hydraulic Connection
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 350 – 500 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

10
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.
Commissioning
Never switch the water heater on without it being lled with water.
Before switching on, open the hot water taps, bleed the pipes until no air
is present and ll the appliance.
Check that the pipes and the door seal under the cover are not leaking.
If there are any leaks tighten gently. Check that the water safety
devices are working and ll the appliance. Switch on the appliance.
After 5 to 20 minutes according to the capacity of the appliance,
water should start dripping from the drain outlet. This is normal
and results from the expansion of the water.
Check that joints and seals are watertight. In the course of heating up,
shielded water heaters may make a boiling noise; this is normal
and does not indicate any fault with the appliance.
To avoid the development of bacteria (legionella…) ensure that a
temperature of 60°C is reached every day. The thermostat is set at
the factory at 65°C. Maximum is 71°C.
User Maintenance
Operates once a month the PTR valve to prevent scaling and verify that it
is not blocked. If this is not done, damage may be caused and the
guarantee invalidated.

11
Maintenance by a qualied person
Remove the scale sludge. Do not scrape or chip at lime scale deposited
on the casing because this may damage the lining
Change the magnesium anode every 2 years or when its diameter is less
than 10 mm. Changing the heating element or the anode requires
the water heater to be drained and the seal changed.
Draining the tank
Turn o the power and the supply of cold water, open the hot water
faucets and manipulate the safety valve before performing these
operations. Ret the heating element and tighten the screws gently
(opposite screws in sequence), check for leaks the next day and
tighten if required.
If the supply cord is damaged, it must be replaced by a special cord or
assembly available from the manufacturer or approved service
agent.
Replaceable parts
Replaceable parts are the thermostat, seals, heating element, boiler
shell, indicator light, magnesium anode and connection cable. The
guarantee requires genuine manufacturer’s parts to be used.

Faulty maintenance voiding warranty
• Abnormal scaling of heating elements or safety unit PTR valve.
• No maintenance of safety unit PTR valve leading to excess pressure.
• Modication of equipment without notifying the manufacturer.
• Use of spare parts not recommended by manufacturer.
Warranty Exclusions
The following warranty exclusions may cause the Atlantic ESWH warranty
to become void. This may also incur a service charge and cost for
parts should they be necessary.

1) Any physical damage caused by impacts or falls when the ESWH is
handled after leaving the factory.
2) Where service is required to reconnect the ESWH operation due
to problems related with abnormal water supply (i.e. high water
pressure above 1,000 kPa before, at system pressure relief), faulty
plumbing supply or downstream connection and/or electrical wir-
ing or major variations in electrical energy supply.
3) Where an 500 kPa pressure limiting valve as shown in the water
circuit diagrams, has not been tted during installation.
4) Where the ESWH fails due to misuse, accidental damage, acts of

14
God, incorrect installation including being located in premises
aected by frost or bad weather (humid, harsh or badly ventilated
atmospheres) or unlicensed service repair work.
5) Any damage resulting from power surge from supply such as acci-
dental high voltage injection or lightning strike.
6) Damage resulting from non-detectable problems due to the inac-
cessible location of the device, and that could have been avoided
by immediately repairing the device if properly located.
7) Claims for damage to walls, foundations (outside), oor coverings &
furnishings (inside), roofs or other losses, directly or indirectly due
to leakage from the Atlantic ESWH.
8) Where the Atlantic ESWH has been powered up before it has been
lled (heating when dry).
9) Where the Atlantic ESWH has suered external corrosion due to
non-watertight piping connections.
10) If the system is either sold and/or repaired or altered by any third
party without the consent of Atlantic Australasia Pty Ltd.
11) Does not cover fair wear & tear, particularly from adverse condi-
tions, for example: corrosion and associated levels of condensation
in the proximity of the HWS.
12) Exclusions due to Water Composition
Water composition varies widely in and New Zealand. 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). Atlantics warranty is therefore excluded where
the water composition is outside these values:
Total dissolved solids >1000 mg/litre or p.p.m.
Electrical Conductivity < 500 and > 800 uS/cm.
Total hardness <150 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 < 6.5 and > 8.5
Water from springs, bores and dams is also excluded from meeting
Warranty conditions because of the rapidly variable composition

15
of these waters due to groundwater salinity and aggressive
mineralisation. Water MUST be from a supplied, reticulated source
or from rainwater to ensure Warranty compliance.
