3. Operating Instructions
3.1. Powering Up
Use the ON/OFF button on the digital controller to power up the unit. If the heat pump
continues operating for approximately 5 minutes, then it is functioning satisfactorily. If the
heat pump stops operating within 5 minutes, then air is still likely to be trapped in the water
pipes. Power off the heat pump and open the hot water taps again for a few more minutes
to let the water flow out, then power up the unit again following the above process.
DO NOT DRILL ANY HOLES INTO THE STORAGE TANK CASING. IT MAY CAUSE DAMAGE
OR LEAKAGE TO THE STORAGE WATER TANK INSIDE AND VOID YOUR WARRANTY
2.21 Corrosion Protection
Fittings to the casing in contact with the water must be galvanically compatible. Sealants
and / or Teflon plumbing tape should be used on potentially galvanically incompatible fittings.
This is to protect against possible electrolytic corrosion between the metals (where moisture
penetration could occur due to incorrectly or poorly sealed fittings).
3.2. Pressure and Temperature Relief Valve Maintenance
The valve lever should be operated at least once
a year to ensure that the water-ways are clear and to remove any mineral deposits from the
valve seat that may cause the PTR valve to leak. When manually operating the lever, water
will discharge. Avoid contact with the hot water to avoid potential scalding.
