INSTALLATION & OWNER’S MANUAL
Thank you very much for purchasing our product,
Before using your unit, please read this manual carefully and keep it for future reference.
ALL IN ONE Type Air-source Heat Pump Water Heater
EcoSpring ES300

HOT WATER CAN BE DANGEROUS
Warning – Hot water burns. As a safety precaution, young children should always be supervised around
hot water fixtures.
Heat pump water heaters can store water at temperatures that can cause scalding. Water temperatures
over 50°C can scald and care needs to be taken to ensure that injuries do not occur through incorrect
use of your water heater.
As heat pump water heaters can generate water temperatures in excess of 60°C, regulations require
that a tempering valve be fitted to the heater to prevent water temperatures going to the home exceed-
ing a preset safe maximum. The tempering valve must be connected to the hot water outlet line from
the water heater. The valve must be fitted by an authorized plumber at the time of installation or in retro-
fitting to existing systems.
Care should be taken to avoid coming into contact with any pipe work or fixtures associated with the
water heater pipe lines. Under NO circumstances should any ‘home handy man’ type modifications be
attempted.
• This appliance is not intended for use by persons (including children) with reduced physical sensory
or mental capabilities, or lack of experience and knowledge, that prevents them from using the appli-
ance safely without supervision or instruction. Children should be supervised by a responsible
person for their safety to ensure that they do not play with the appliance.
• DANGER: Failure to operate the relief valve easing gear at least once every six months may result
in the water heater exploding. Continuous leakage of water from the valve may indicate a problem
with the water heater.
• THE INSTALLATION MUST COMPLY WITH THE REQUIREMENTS OF AS/NZS 3500.4, AS/NZS 3000, and
all local codes and regulatory authority requirements. In New Zealand, the installation must conform
to the New Zealand Building Code G12.
The power supply must be protected by an individual circuit breaker at the main electrical supply
switchboard and rated to suit the booster size. The supply to the heat pump water heater can be oper-
ated directly from the switchboard or via a remotely mounted switch or time clock as requested by the
customer. The heater must be provided with a suitable means for disconnecting the power supply.
WARNING
This unit is required reliable earthing
before usage, may otherwise result in
death or injury.
If you can't make sure that your house power supply is earthed
well, please don't install the unit.

1. BASIC OPERATION PRINCIPLE
We know from experience, the natural flow of heat, moves from a
higher to a lower temperature source, a heat pump can transfer heat
from a lower temperature source to a higher temperature source with
high efficiency.
The advantage of a heat pump water heater is that it can supply more
heat energy, normally 3:1 times than input electricity power by
extracting the heat from ambient atmosphere in a free-of charge way
and transfer to Sanitary Hot Water. Compared to a traditional water
heater, such as electric water heater or gas burner water heater, their
efficiency is normally less than 1:1, which means you can dramatically
cut off the bill of family daily SHW by the application of heat pump
water heater, the following examples will show more details.
Power consumption comparison under the same condition to heat 1
ton of water from 15˚C to 55˚C.

When ambient temperature does not meet the heat
pump operational requirement (outside the range -7~43℃) for
over 20 hours. “LA” will display at TEMP-SET screen and
ALARM indicator flashes simultaneously to alarm that the
temperature is not suitable for heat pump performance, only
E-heater mode could be selected at such circumstance.
Please switch to E-heater mode manually to ensure there
is adequate hot water to be supplied. Note that if change of
mode is done manually, the desired mode will not return
automatically upon unit returning to normal working process.
Desired mode must be changed back manually.

Before start, please check the following first:
Correct installation of the system;
Correct connection of pipeline, wiring and earthing;
Drainpipe connected;
Suitable pipe insularion;
Correct transportation of unit;
Correct power supply;
No obstacles outside the air inlet and outlet;
Complete bleeding air out of hot water cylinder and pipes;
Effective electric leakage protector;
Sufficient inlet water pressure(≥150kPa)
Water-heating Operating Capability
There are three types of heat sources that can be used by the
heat pump water heater: electric element, heat pump and coil.
These three sources do not work together at the same
time. Do not use the coil without consulting the supplier.
This unit has two temperature sensors in the hot water cylinder,
they are installed at the upper 1/4 and bottom 1/2. The upper one
tests the upper temperature, shown in the figure below, and the
bottom one is used to test the lower water temperature, which
will control the operation of the heating automatically.
Water-heating Operating Modes
: In this mode, the unit heats water only by compressor
drive according to heat-pump principle.
(Water outlet temp. range 38～60 ℃ ,running ambient -7～43 ℃)
: In this mode, the system will adjust the working
capabilities of electric element and heat pump according to the
tank water temperature.
(Water outlet temp. range 38～60 ℃ ,running ambient -30～43 ℃)

Heat-up Time
E-HEATER MODE
Hybrid Mode: -30~43℃
E-heater Mode: -30~43℃
Water Temperature Display
The temperature on the display is the water temperature in the
upper part of the water tank this is approximately 75L of water
The 6 indicators beside the water temperature on the display
are for the temperature in the lower part of the tank. When the
temperature is higher than 40℃, the blue indicator will light up;
when higher than 50℃, the yellow indicator will also light up;
when higher than 60℃, all three colour indicators (blue, yellow
and red) will light up. When all indicators light up, the water
temperature has reached the set point.
When using water, the temperature of the lower part may
decrease while the upper part still keeps at a high one, and the
system will start heating the lower part. This is normal.
Trouble Shooting
When error code appears on the display or the unit is not
operating, please contact your installer.
When an error occur, the buzzer will buzz in every minute,
the warning light flashes, the display will indicate the error code
and water temperature alternatively. Press CANCEL button for
3 seconds to stop the alarm.
Restart after a period of disuse over one year
Please follow the draining and filling water instructions on
page 10 to refill the water.
NOTE
Economy mode should be used when the ambient temperature
is between -7～43℃. When the ambient temperature is under
-7℃, the energy efficiency would decrease, E-heater mode
should be used in this circumstance.
NOTE
In the E-heater mode, the water above the electric element that
is being heated is approximately 150L.
: In this mode, the compressor and the fan motor will
not run but the electric element work only.
(Water outlet temp. range 38～60 ℃ ，running ambient
-30～43 ℃).
Defrost during Water-heating
In the Economy and Hybrid Modes, if the evaporator froze
in a cold environment, the system will defrost automatically.
(3~10 min).
Ambient Temperature
The system’s operation temperature is within -30~43℃and
below are the operation temperature for each mode.
Economy Mode: -7~43℃
NOTE
If the unit fails to restart after self-protection, Switch the power
supply off manually and restart after the error has been resolved.
Mode Selection
Different modes are designed to meet different demand and the
following are recommended selections.
Economy Mode: -7~43℃, continuous hot water demand below
250L (60℃);
Hybrid Mode: -30~43℃, continuous hot water demand between
300L~350L (60℃);
E-heater Mode: -30~43℃, continuous hot water demand around
150L (60℃).
Self-Protection
Self protection starts in the following circumstances:
Air inlet or outlet is blocked; Error Code: P1
The filter is covered with too much dust; Error Code: P2
Incorrect power supply (exceeding the range of 220-240V)
Error Code: P4
When self-protection occurs, the system will stop and begin
self-check, and restart when the problem is resolved; system will
not restart automatically if problem persists, in such case,
contact your installer
When the self-protection happens, the buzzer will buzz every
minute, the ALARM indicator flashes and the display indicates the
error code and water temperature alternatively. Press CANCEL
key for 3 seconds to stop the alarm. Buzzing and flashing stops
