Page 2: Pre-Installation
Pre-Installation Pre-Installation Important Site Instructions The installation, commissioning, inspection, maintenance and repairs must only be carried out by a qualified person. All electrical wiring must be completed by a licensed electrical contractor in accordance with the appropriate standards. The drilling work requires a permit from your local council. The heating system and heat source must be properly designed and dimensioned to ensure an efficient operation. -
Page 3: Installation Location And Positioning
Installation Location and Positioning Installation Location and Positioning The unit must be installed in a protected area that is free from rain and water penetration. The unit must be installed on a solid level surface, preferably on a concrete pad not connected to the main house slab foundation. -
Page 4: Buffer Tank
Buffer Tank Buffer Tank A buffer tank is recommended to ensure a trouble free heat pump operation. A suitable buffer tank can avoid excessive heat pump cycling (switching on and off). The buffer tank provides a hydraulic separation from the volume flow in the heat pump and heating circuits. - Page 5 Systems Overview (Outdoor side) System Overview Vertical Ground Loop System Name Description Location Name Description Location Outdoor side water Outdoor temperature External Internal pump sensor Safety valve External Particle filter External Brine tank/expansion External tank...

Each controller is set to different cooling, heating set point (2-3 degree difference)so they will not start at the same time to reduce start current. All units water pump control signal connected together to A/C contactor which supply power for water pump so the water pump can run as long as any unit is running.
- Page 9 Systems Overview (Indoor side) Heating working principle: To set two units in parallel operation, set the primary unit to the required parameters, unit two is to have 3~5°C difference of ST01,ST02 and ST05 to allow for energy stage control. Switch on both units’ A/C switches one by one, if the RT parameter is lower than the set values of both units, then the units will start to heat together.

Page 10: Installation
Installation Installation Installation must be carried out in accordance with current Standards and Building Codes ． T he heat pump does not come fitted with shutoff valves and these must be fitted outside of the heat pump to facilitate future service ．... - Page 11 Installation Where there is more than one ground loop these must be connected in parallel with a means of adjusting the flow. For surface soil heat, the pipe should be buried at a depth of about 1.8 meters and the distance between the hoses should be at least 1 meter. For bore holes the distance between the holes must be at least 15m.

Page 14: Outdoor Ambient Temperature Sensor
Electrical Connection Outdoor Ambient Temperature Sensor: The outdoor temperature sensor (OT) is a standard part placed inside the electric box. One terminal is connected with the PC board X3 and GND, the other terminal must be installed outdoors. It should be mounted on a wall that has the mean outdoor temperature which can accurately measure the outdoor temperature and not to be exposed the rain, sun and snow. - Page 15 Electrical Connection Outdoor Side Water Pump: Outdoor side water pump is connected to terminal port (1-2). If the water pump current is over 2A, an A/C contactor must be used to activate the water pump. Indoor Side Water Pump: Indoor side water pump is connected to terminal port (3-4). If the water pump current is over 2A, an A/C contactor must be used to activate the water pump.
