•Maximum load allowed to be connected to HW terminal is 4.8kW.
•Cable sizing must be chosen based on the AS3000 wiring standard.
•The Diverter must be protected from weather. The recommended
installation location is inside the meter box.

The clearance specifications below are recommended clearances. If the
clearances cannot be achieved the diverter will de rate if needed to
accommodate the installation environment.
IMPORTANT
Case temperature can reach 60oC.
Ensure the diverter is not placed next to anything
that can be affected by moderate temperatures.

1 – INSTALL MOUNTING PLATE
The clearance specifications above are recommended clearances. If the clearances
cannot be achieved the diverter will derate if needed to accommodate the
installation environment.
1.1 – Detach mounting plate from unit.
Remove the 4 screws from the bottom
guard and remove the guard.
Slide the mounting plate down towards
the bottom of the unit then pull it out
as shown.

1.2 - Fix the mounting plate to a flat surface using the four bolt holes
on the plate.
1.3 - Drill cable entry holes based on dimensions shown.

•The arrows next to the CT’s in the wiring diagram represent the
arrows on the inside of the CT’s.
•Matching the CT’s to the correct phase is critically important
special care must be taken to ensure this happens.
•NEVER disconnect CT’s from diverter while they are wrapped
around a current carrying conductor.
•If Controlled Load Off Peak is not available leave the Off Peak
connection empty.
•Multiple wires can be put through the CT, as long as all currents are
in the same direction.
•Some electrical jurisdictions do not allow switches in the Off Peak
circuit, if this is your case then do not connect the off peak circuit.

•All electrical work must be carried out in accordance with AS3000.
•Hot water isolator is not required if 20A double pole breaker
clearly label as hot water.
•Off Peak MUST be on the same phase as the MAINS terminal.

It is important to ensure cable termination is neat and tidy into the terminal blocks
to ensure there is no risk of active conductors migrating to earthing screws.
The recommended cable profile is show below.
2.1 – Cable termination into the device

•Ensure cables are position so that no long term load is applied to
terminal blocks.
•Ensure all terminal block screws are screwed in tight, even the
ones that are not used.

It is vitally important the CT’s are
pointing in the right direction.

•Replace the bottom guard ensuring all cables are not touching the guard.
•Replace all screws ensuring the tooth washers are used for the screws exposed
at the top of the guard.
2.3 – Replace Bottom Guard

Catch has been designed with simplicity in mind. The interface has only 4 buttons.
3 – How to Control Catch
1. Power light
The power light indicates the unit has power to it and is ready to operate. Most of the time this led
will be solid green.
If you see the power led flashing on and off it means the unit is restricting power delivery to the hot
water because it is getting hot.
The device getting hot is not an indication of a problem, the small form factor means there will be
times the unit needs to slow down because it is getting hot.
1. Diverting light
The diverting light indicates how much energy is being sent to the hot water service. The faster the
diverting light is flashing the more energy is being sent to the hot water.
If the diverting light is solid green it means the unit is as at 100%, which means Catch is sending as
much power as the hot water element can handle.
If the diverting light is off and you see a very short pulse of light every few seconds it means the hot
water service has hit temperature and the hot water thermostat has shut the element off.

Understanding the CATCH buttons
Each button on the control console represents a different mode of operation. You change modes by
gently pressing on the round circle that represents each button. Catch will let you know if it has
changed modes by the green LED lighting up on the button you have just pressed.
3. Heat Now Button
The Heat Now mode is entered into by pressing the Heat now button.
The Heat Now mode is used to get your hot water heated as soon as you press the button. In this
mode the device will first check to see if it can you power from the Off Peak line. If the off peak is
not installed or is not available then it will use normal mains power.
Once the hot water service hits thermal cut off CATCH will move out of Heat now mode and go back
into Boost 5hrs mode.
Heat Now Lock mode can be entered by pressing the Heat Now button a second time. Catch will tell
you it is in Heat Now Lock mode by flashing the led on the Heat Now Button on and off.
When Catch is in Heat Now Lock mode CATCH stay in Heat Now mode until you manually change it
to another mode.
4. Boost 5 Button
The Boost 5Hrs mode means Catch will attempt to use 5hs of Off Peak energy each day as well as
the excess solar energy to heat hot water.
5. Boost 2.5 Button
The Boost 2.5Hrs mode means Catch will attempt to use 2.55hs of Off Peak energy each day as well
as the excess solar energy to heat hot water.
6. Solar Only Button
The Solar Only mode means Catch will not use any Off Peak energy to heat hot water. The only
energy that will be sent to the hot water service is solar energy that would have otherwise been
exported to the grid.
