Page 32: Commissioning
COMMISSIONING TO FILL AND TURN ON THE WATER HEATER The power supply to the water heater must not be switched on until the water heater is filled with water and a satisfactory megger reading is obtained. Open all of the hot water taps in the house (don‟t forget the shower). Connect a 6 mm diameter clear plastic hose to the spigot of the air bleed valve, located on the heat pump flow line at the connection to the storage tank.
Page 33 COMMISSIONING Note: The heat pump may not turn on after having just completed a heating cycle and more hot water is drawn from the water heater. The heat pump will wait until the compressor has cooled down and the conditions for start up are favourable, in order to protect the compressor from damage.
Page 34 COMMISSIONING DIAGNOSTIC FEATURES OF THE HEAT PUMP CONTROLLER An operating mode monitor is located on the front of the heat pump module and houses a green and a red LED. The green LED, marked “NORMAL”, indicates the current operating mode of the heat pump water heater and the red LED, marked “ATTENTION”, indicates a fault mode.
Page 35 COMMISSIONING Notes: Power must be available at the water heater and to the heat pump for the LEDs to glow or flash. Time controlled power supply If the water heater is connected to a time controlled power supply, then during periods of no power supply at the water heater the LEDs will be off.
Page 36: Water Supplies
WATER SUPPLIES This water heater must be installed in accordance with this advice to be covered by the warranty. This water heater is manufactured to suit the water conditions of most public reticulated water supplies. However, there are some known water chemistries which can have detrimental effects on the water heater and its operation and / or life expectancy.
Page 37 WATER SUPPLIES CHLORIDE AND PH Where the chloride level exceeds 250 mg/L warranty does not apply to the water heater. In a high chloride water supply, the water can corrode stainless steel parts and cause them to fail. Where the pH is less than 6.0 warranty does not apply to the water heater. pH is a measure of whether the water is alkaline or acid.
