If you believe your Sanden Eco Heat Pump is not producing hot water, please try the following:

1. Unless there is water pouring (not dripping) out of the unit, do not turn the unit off and on until you've checked the clock / control panel for an error message (under our "Resources" section you can find the different error code pages to help you determine what an error code looks like). If water is pouring out then turn the unit off at the isolator and at the switchboard that circuit is attached to.
2. Pull the PTR Valve on the Tank - this confirms if there is hot water in the tank. If unsure about the water temperature use a thermometer. If water is cold goto (2) If there is 50C or so hot water in the tank then the problem is not the heat pump system) the problem is on the house side of the tank.  So the tempering valve needs to be checked for a blockage / choke, if it is installed upside down or if it has failed (they are consumable items with a lifespan of 5-6 years and they fail to safe when they fail meaning cold water).
3. Check the electricity supply - Confirm/check both (1) circuit breaker at the switchboard is ON + (2) Isolator at the HP unit is ON
4. If you see a little Red Dot in the bottom right corner, then the HP unit has power connected. For the older G2 model 2010-2016 the dot is on the controller hidden under the lid - you will need a screwdriver to remove the 4 screws from the each end of the lid.
5. Check if there are any Error Codes at the clock/computer control panel. If an error code is present, take note of the Error Code. Turn off the HP at the isolator (wait 1 minute) and turn on the HP again to see if the Error Code re-appears. The unit is functioning correctly if it blows cold air for more than 30minutes. NOTE: The unit takes about 7 minutes to start blowing cold air after power is applied.
6. If system is newly installed or new plumbing works have occurred on site confirm that the tempering safety valve (valve with orange/yellow cap) is installed the right way up with a H on the vertical barrel above the adjustable valve and a C below the adjustable valve. If the system is more than 5 years old please note these valves officially only have a minimum life span of 5 years and may need replacing.
7. Air bleed the system - Open the water drain plugs on the right hand side of the HP unit (one at a time for a good 3 minutes PER drain plug, ONE at a time). G4 units have an additional bleed port on the underside of the heat pump - please only turn this 180 degrees approx when opening it up - bleed this for 3 minutes also.  Re-set the HP unit at the Isolator.
8. Hard re-set the HP unit controller:
   1. Switch off power to the HP
   2. With power switched off press and hold down both “Up” and “Down” keys on the control panel simultaneously
   3. With the keys still pressed switch on power to the unit, the display will show “FClr” .... wait 10 seconds.
   4. To complete the reset cycle power to the unit off (wait 1 minute) and then on again.
   5. With power back on the time will be displayed (if required adjust to correct time) and the unit will run it's start up procedure.
   6. When switching power on again, the country setting "1.AU" may appear on the display. If for any reasons this setting remains on the display, simply press "Enter" and the Control Panel to confirm and HP will continue the start-up process.
9. Physical inspection of the HP
   1. Turn off the electrical isolator, to allow power to discharge, wait 5 minutes after the power is turned off
   2. Take the top panel off by unscrewing the 4x screws
   3. Check to see if any debris/foreign objects are the top of the unit
10. If an onsite plumber or electrician has a volt meter check for ~230VAC at the terminals on the side of the unit.
11. If you have an older G2 unit and E124 is displaying then the unit has been subject to either high grid voltages or has suffered a power spike. Adding a timer to the switchboard and keeping the unit powered off for more than 19 hours per day can clear the fault for each and every use. This is successful in 50% of cases however works better where it is done the first time the error is ever seen. Not where the unit has been turned on and off many times.
12. If you are getting E040 on an older G2 unit then you can clean the filter via the filter housing at the bottom of the unit adjacent the air bleed drain plugs. This may get you up and running again temporarily while you book a service. BOOK YOUR SERVICE OPTION HERE
13. For blockages in newer units a 3 way ball valve can be installed which allows the consumer to perform their own reverse flush of the system. This maintenance step is normally part of a 4 year service can then be done annually just before the air bleed is performed.

If you have a Sanden Eco heat pump hot water system that is working but you find you're running out of hot water before your Sanden commences it's daily start up - this is most likely because you have a block out time period not suitable for your hot water load consumption.

Rectification is to change the Bllockout timer setting on your Sanden Eco heat pump (condenser unit) to either of the below Scenarios:

Most likely your current BO Timer is set up with a 5 hour period (e.g. "1611"- 11am to 4pm) - change this to either:

Scenario 1: Amend your Blockout Timer with a longer time period e.g. 0211

Keep the 'start' time of your Blockout Timer the same e.g. 11am to maximise rooftop solar PV production and change the 'end' time to e.g. 2am the next  morning.

Your BO time on the control panel should read "0211" in this scenario.

Scenario 2: Disable the Blockout Timer 

Find you're still running out of hot water? Disable the blockout timer.

Change the 'start' time of the Blockout Timer to "00" and change the 'end' time of the Blockout Timer to "00"

Your BO time on the control panel should read "0000" in this scenario.

Getting access to block out timer mode

Note:  After installation only 'maintenance mode' should be used for block out changes.  There is another procedure on page 16 of the installation manual related to the block out timer this only applies when the unit is first installed. 

To set the block out timer for your Sanden unit you will need to access the 'clock control unit' (shown below in blue), to do this you will need to remove the four screws at the side of the top cover panel on your outdoor unit (shown below), which has a 10 mm lip around the entire unit, to access.

Once you have access to the clock control unit you can set the block out (BO) timer by following the steps below, this will allow you to set your block out hours.  

1 - Hold down "UP" and "DOWN" together - gets you to "HSE" mode

2 - Press "UP" - gets you to outlet water temp setting mode

3 - Press "UP" - gets you to BO mode

4 - Press "ENTER" - gets you to EDIT BO mode (then enter the hours accordingly).

For more information consult page (17-22) of your Sanden installation manual which can be found here. 

Setting the hours you want to block out

The block out time functions using four digits first two digits = off, second two digits = on so:

To set the timer to run between 12 midday (AEST) and 6 pm set the blackout timer to 1812, which means off at 6 pm (18 in 24 hr clock terms) and on at 12 pm. 

To set the black out timer to run off-peak you might choose 0722 which means on at 10 pm (in 24 hr notation) and off at 7 am. Ensure that the off-peak tariff supplies a minimum of 5 hours continuous power to the Sanden HPHW.

If in doubt don't hesitate to contact us at  info@pure-electric.com.au and we can guide you through the process

How does an solar panel ground fault, insulation fault occur and how do you resolve it?

Where there is a lot of moisture in the area (typically humid conditions or a rainy day), this is when you would notice an isolation fault. Identifying when a fault occurs is only possible when the isolation error presents. Typically you will notice the isolation fault in the morning which sometimes disappears as soon as the moisture resolves (can be a few minutes, few hours). In some cases, it is difficult to identify what has caused the isolation fault. Typically it is due to either poor quality panels or a poor quality solar PV rooftop installation.

This means the solar inverter error isn’t actually broken, or usually, it isn’t the solar inverter failing.

How does an isolation fault occur?

If the shielding on the wiring is damaged during fitting, a short circuit may occur in the DC area of the solar PV system. This is what we call an isolation fault. Besides a problem with the cable shielding, an isolation fault could also be caused by moisture or a bad connection in the solar panel’s junction box. 

The error message that appears on the inverter screen is “isolation error” or “isolation fault”. For safety reasons, as long as this fault exists, the inverter will not convert any power as there may be life-threatening current on the conductive parts of the system.

How to resolve if it continues to repeat?

A licensed electrician is required to check the system to try and find the cause of the fault. If the fault can't be located (e.g. multiple sources), then new solar PV panel system and installation is most likely the ultimate solution.
