- Page 2 Foundations & Drainage When siting the heatpump at ground level, the recommended method of mounting the heatpump is to make a rectangular base from concrete house stumps lying on their sides, and topped with expanded foam. If a slab has been prepared, it is still best to use the stumps to raise the unit above the ground. There are many drain holes in the base of the unit.

Page 5: Recommended Clearances
Recommended clearances: For V-Models: Notes: This plan is a guide only. It assumes that two sides are closed No more than two sides should be closed Overhanging structures such as eaves should be avoided Waste cold air must not be allowed to back-feed into the heatpump Access must be provided for service If only one side is closed then the 500mm clearance can be reduced to 300mm... - Page 6 Recommended clearances: For SX-20BZA/SX-21ZA – SX-26ZA-Models: Notes: This plan is a guide only.

- Page 7 Water flow-rate in the primary circuit: Before anything else you MUST plan to achieve the required water flow rate in the primary circuit between the heatpump and buffertank. Adequate water flow-rate is critical to achieve maximum efficiency. (Just because a unit is heating does not mean its running efficiently) Avoid restrictive plumbing.
- Page 8 Airflow: In general, all Skyline Energy dual-compressor, top draught, hydrocarbon hydronic heatpumps require at least 2m clearance on two sides. There should be no large objects within 2 meters above the fans. Fresh air flow is critical... You must avoid the possibility of waste cold air back-feeding to the unit and driving down its efficiency.

- Page 12 Electrical install notes: Room thermostat wiring to be 1.0mm or 1.5mm TPS. Room thermostats to be placed in a horizontal wall plate @ 1500mm above floor level. Locate room thermostats away from heat sources e.g. ovens, radiators, aircons or sunlight. The minimum capacity circuit breaker is as per the table, but be aware of higher than normal grid voltage that can make the units draw more current than posted.
- Page 15 *Specifications: NOTES: kW input and outputs Amps are rated at 230V. Higher supply voltages can drive the input current a lot higher than specified. Circulation pump loads are not included in kW input ranges, however an allowance for these loads has been made in circuit size recommendations.
- Page 16 Real World Testing: Unlike most heat-pump manufacturers, we test every unit in the ambient temperature range where they are really meant to operate. We test and fine-tune EVERY unit prior to dispatch and ensure that it’s C.O.P. is as high as possible. Claims by others of C.O.P.’s of 4 or 5, may be correct in a lab with a standard test condition of 20C ambient and a water temp of 15C, but the C.O.P.’s of these units will be much lower at lower ambient air temperature and higher...
- Page 17 Flowrate is critical to efficiency and must be kept within specs. Placing the heatpump close to a carport or veranda can amplify sound level. Skyline Energy will not be responsible for poor placement of heatpumps that create noise problems.
- Page 18 Configurations: The heatpump and buffertank can be sited side-by-side or the heatpump located 50 or more metres from the buffertank, but in all cases the primary flow and return water pipes should be of adequate size, and the primary circulation pump of adequate size to provide the required water flow rate.

Page 19: Typical Installation Diagram
Typical installation diagram:... - Page 20 Bleeding and Buffertank The most common failure at commissioning is created by excess air, an air blockage causing no water flow. If the compressor shuts down about 20 seconds after starting 95% CHANCE, YOU HAVE AN AIR-LOCK After initial commissioning, the auto air bleed valve on the top of the tank should expel most of the air.
- Page 21 Onsite-testing heatpump output: There is an onsite test to prove the efficiency of the system, measuring the time it takes for the buffertank to heat. This test will always give a slightly lower result because of the losses that will be in any buffertank system.

Page 28: Operation
Operation: The system is primarily driven from the room thermostat(s). Room thermostat(s) directly controls the zone circulation pump(s) and may kickstart the buffertank controller. Zone pump delivers water to the floorcoils or radiators. When the room thermostat(s) call for heat, the buffertank controller fires-up and will make a decision based on the buffertank water temperature, to energize the primary circulation pump and start the heatpump. - Page 29 Part 1: Operating panel introduction 1.
