This document describes an integrated heat pump water heater, V Series R134a, designed for heating water for domestic or commercial use. The manual emphasizes that the installation, maintenance, and repair of this water heater must strictly adhere to the appropriate and relevant requirements of SANS 10254. Users are advised to read the manual carefully before installation and maintenance and to keep it for future reference.
The air source heat pump water heater utilizes ambient air to heat water, providing an energy-efficient solution for hot water needs. This technology is presented as a modern alternative to traditional heating methods such as coal, electrical, gas, and solar water heating, offering benefits in energy saving and environmental protection. The unit is designed to operate automatically with microcomputer control and a timer function, allowing it to start and stop based on set water temperature and other running conditions without requiring constant supervision.
Safety: The device prioritizes safety with complete isolation between water and electricity, eliminating the risk of electric shock associated with traditional electrical water heaters. It also avoids the dangers of fuel tubes and storage, such as oil leakage, fire, or explosion. A comprehensive range of protection features is integrated, including compressor delay protection, water-pressure check switch, high and low-pressure protection, super heating protection, anti-phase and open-phase protection, and high-temperature protection. A leakage protection switch must be installed near the heat pump in an accessible location. Users are warned against using damaged wires or switches and must replace them immediately if found. The electrical box should not be opened without first shutting off all power sources to the heat pump.
Transportation and Installation: During transportation, the heat pump must be kept upright and not tilted more than 45 degrees in any direction. Proper installation location is crucial, requiring good ventilation, proximity to a drainage channel for condensate water discharge, and a smooth, horizontal surface capable of supporting the unit's weight to prevent noise and vibration. The unit should not be installed in areas with pollution, dirt accumulation, fallen leaves, or near inflammable or explosive materials. A wye strainer must be installed before the water inlet to prevent system clogging, and a relief valve is an essential requirement for the water tank. Installing a mixing valve in the user's hot water system is recommended to increase the utilization rate of hot water. The heat pump must be fixed to prevent toppling.
Operation: Trial operation should only be performed by a qualified technician to ensure correct start-up. The unit is designed to operate within an ambient temperature range of 0°C to 43°C and a water pressure range of 0.15 to 0.8 MPa. The water outlet temperature can range from 28°C to 75°C, with a default hot water temperature of 60°C. Before commissioning, the piping system and water tank must be filled; the unit should not be turned on until water flows from the hot water outlet, indicating a full tank. Once the tank is full, the unit can be powered on and observed for normal operation.
