Warning
This device is not intended for use by persons (including children) with
physical, sensory or mental disability, or by persons lacking experience or
knowledge, unless they have received from a person in charge of their
safety adequate supervision or preliminary instructions on how to use
the device. Care must be at all times to keep children from playing with
the device.
Caution
Heavy item, handle with care
• Install the appliance in a room that is protected from frost. If the
appliance is damaged because the PTR valve safety device has
been blocked, it is not covered by warranty.
• If the appliance is to be tted in a room or location where the
ambient temperature is higher than 35°C, sucient ventilation
must be provided.
• It is compulsory to t a tray/ sump below the water heater if
mounted in a suspended ceiling, under a roof or above living area.
Position the appliance where it can be accessed.
• Make sure that the wall and or oor on which the appliance is
mounted can support the weight of the appliance when lled with
water.
• This device is intended for use at a maximum altitude of 3000 m.

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 result of both water
expansion during heating and also pressure uctuations.
The supplied PTR valve must be tted with Teon tape - don’t use paste or hemp.

6
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.
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.
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.
Install the Di-electric connector between the hot water outlet and T-piece.
The connector prevents corrosion.

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
