Introduction
The DynaHeat™heat pump water heater system has been designed using the latest refrigeration
technology to remove the heat from the air to heat water. The refrigerant we use is R410a which does
not contribute to global warming, so it allows us to help keep a clean, healthy earth for future
generations.
By using R410a as the refrigerant we have produced one of the most energy efficient units currently
available. It’s even more efficient when connected to off-peak power.
How it works
The heat pump water heater system heats water by transferring the heat from the surrounding air to the
water using a refrigerant. The refrigerant is heated by a heat exchanger that absorbs heat from the
surrounding air (Figure 1).
Note:
Operating conditions may vary depending on the type of off peak tariff that is available in your area. The
unit must have a minimum of 5 hours continuous power available at all times to allow the unit to operate
without affecting reliability.

Trouble Shooting Guide
Should a problem arise while the heat pump is in use, please check the following things prior to calling
for support:
STATUS POSSIBLE CAUSES ACTION TO TAKE
No hot water
comes out of
water tap
Temperature
of hot water is
too low
Small or no hot water is left in
the storage tank.
•Stop using hot water and wait for about an
hour.
•Consider a change of the electricity supply
from off-peak mode (length of power supply
hours may be too short for the water
heating cycle to cover the hot water
consumption).
Air removing procedure from the
heat pump system may be
insufficient.
•Open the water drain plugs on the heat
pump unit to remove air from the water
circuit. (be careful of burning).
Filter on cold inlet connector
may be blocked.
•Check the filter and remove if there is any
blockage.
Water flow speed may be
dropped due to the heat pump
piping being bent, crushed or
blocked.
•Check if any of the piping is bent or
crushed. Remove any kinks if possible.
Pipes may be frozen. •If frozen area is found on the piping, melt
the ice on the pipe and provide a heat
insulation.
Stop valve is closed. •Open the valve.
Air absorption is not sufficient
due to a blockage on the
evaporator.
•Remove the object blocking the air flow
through the evaporator (e.g. Fallen leaves,
grass, snow, etc.).
For those problems not listed in the list above, an inspection provided by a skilled engineer is required.
Please contact the distributor.
Caution:
Do not shut down the electricity supplied to the heat pump system even if you go away from home and
hot water is not in use for a long time.

10
Removing Air from the System
•The following steps must be taken to ensure all air is removed from the system. Incorrect removal
of air may cause the water temperature to vary.
•Plumb pipes to the tank unit and the heat pump unit.
•Push the lever up on PTR valve to open and fill the tank unit with water.
•Confirm that the water comes out of the relief valve and then close the lever.
•Open the hot water taps in the home to remove air.
•Close the hot water taps in the home after no air is confirmed in the water.
Figure 4: Air removing process
Plumb pipes to storage tank unit and heat pump
unit.
Push lever on the PTR valve to open and fill in
the tank with water.
Confirm that water is coming out of the relief
valve and then close the lever.
Relief valve leading gear should be operated at
least once every six months. If water does not
discharge freely when the lever is operated, the
valve should be checked by an authorised
agent.
Electrical Connections
•Electrical installation should be done by a licenced electrician who carries out the work according
to the relevant regulations for electrical safety and wiring.
•Follow the wiring rules for the breaker rating and the thickness of the electrical wiring.
•Verify that the tank unit is full of water and the water stop valves are open before turning on the
power.
System Operation Outline Continuous Power
•The system runs its water heating cycle once a day to fill up the storage tank unit with heated
water.
•If the block out time function selected the unit will not operate during block out times. This function
is typically used on installations that have time of use electricity tariffs.
•The water heating cycle operation starts automatically when the residual hot water in the tank unit
becomes less than 45◦C.
•The system will not run if the electrical power supply is cut off (i.e. if it is connected to off-peak
power). However, the system will automatically start operation once the electricity becomes
available.

System Operation If Connected To Off Peak Electricity
•There are no special settings for the off-peak connection. The system will run once the power
becomes available and the temperature in the tank drops below the set point of the tank thermistor.
If connecting the unit to off-peak, ensure that the off peak tariff provides a minimum of 2 hours
continuous power, as it can take at least 2 hours to fill the tank unit with hot water. If the ambient
temperature is lower than 10◦C, this can be longer.
•If the unit is connected to off peak and consumption has been higher than usual, hot water might
not be available until the next power supply cycle.
•Daily frequency and amount of hot water consumption may also affect the duration of the heating
cycle operation.
Select the electrical supply mode that best suits the customer’s hot water consumption. The type
of off peak connection may need to be changed if hot water supply is not maintained as required.

Water Supply Quality
Chloride and pH
In high chloride water supply areas, the water can corrode some parts and cause them to fail. Where the
chloride level exceeds 200mg/litre, warranty does not apply to the heat pump unit and tank unit. pH is a
measure of whether the water is alkaline or acid. In an acidic water supply, the water can attack the parts
and cause them to fail.
No warranty applies to the heat pump unit and tank unit where the pH is less than 6.0. The water supply
from a rainwater tank unit in a metropolitan area is likely to be corrosive due to the dissolution of
atmospheric contaminants.
Water with a pH of less than 6.0 may be treated to raise the pH. It is recommended that an analysis of
the water from a rainwater tank be conducted before connecting this type of water supply to the system.
Figure 6:
Change of Water Supply
Changing or altering from one water supply to another can have detrimental effects on the operation
and/or the life expectancy of the water tank unit cylinder, PTR valve, water heating circulation and the
heat exchanger in the system. Where there is a changeover from one supply to another, for example, a
rainwater tank supply, desalinated water supply, public reticulated water supply or water brought in from
another supply, then water chemistry information should be sought from the supplier, or the water
should be tested to ensure it meets the warranty requirements in this installation manual.
Circulating Water Pump Flow
Changing or alternating from one supply to another can have a detrimental effect on flow rate in loop
between heat pump and tank: 390L/h; actual measurement: 6.5L/min (6.5L x 60min = 390L/hour).
Periodic Inspection: Contact Eco Alliance Pty Ltd for Servicing Quotes
•It is recommended that a periodic inspection of the operating controls, heating elements and wiring
should be made by service personnel qualified in electric appliance repair. Most electrical
appliances, even when new, make some sound when in operation. If the hissing or singing sound
level increases excessively, please contact your dealer.
•Additionally, it is also recommended that the evaporator and refrigeration circuit are checked every
two years for dust and residues. In dusty environments it may be necessary to have the appliance
checked and cleaned on a more regular basis.
•Relief valve leading gear should be operated AT LEAST ONCE EVERY SIX MONTHS. If water
does not discharge freely when the lever is operated, the valve should be checked by an
authorised agent.
