Wide range of operation
UHA series air source heat pump water heater, with wider operation range, can realize normal operation from
-10°C to 43°C. Breaking the limit that traditional heat pump hot water unit can only be used in most southern
areas, UHA series of units are also applicable in most of northern areas.
Expand application of hot water units
UHA series air source heat pump water heater, breaks the traditional bound of domestic hot water, it can
also be used for fan coil units, radiator, oor heating and other hot water demands, according to different
customer requirments.
High EER
Air-cooled heat pump coheres forty years of experience, has introduced efcient and green new products,
help build energyefficient society. UHA series air source heat pump water heater obtained national
energysaving product certication, and were included in the government procurement list of energy-saving
products. The unit, at standard conditions, reaches the highest COP 4.59, an industry-leading level.
Dedicated compressor for hot water unit
UHA series air source heat pump water heater adopts a dedicated compressor. In its unique "spray liquid"
design, during low temperature running status, liquid refrigerant is sprayed into the middle of the scroll
compressor cooling chamber to cool down effectively and reduce the exhaust gas temperature, so as to
ensure the reliability and security. By advanced system design with special "spray liquid" compressor, the
operating range and efciency are greatly improved, to provide stable year-round hot water.
Environmental-friendly rerigerant
The unit uses environmentally friendly refrigerant R410A, ODP = 0. It does not destroy the ozone layer. The
unit integrate R410A and new technologies to provide customers with more efcient, more environmentally
friendly and more economical systems.
No exhaust emission
The unit is without waste gas, water, residue or other harmful substances, nor will it generate any
atmospheric pollution. It's green and environmentally friendly; while absorbing heat when the unit is running,
in summer it improves the surrounding environment, alleviate the urban heat island effect.
Temperature & level limit replenishment function
The unit, of its original "temperature & level limit replenishment function", is dual controlled by water tank hot
water temperature and water level to decide whether to rell water. When the tank temperature is below the
set temperature, it stops relling the water, avoid water temperature uctuates too much during peak of water
use. It provides a stable temperature, to ensure comfort.

LCD controller
Using humanized microcomputer control system, LCD display controller, the unit is simple and quick to
use. Single controller can control up to 16 units, monitor unit running status dynamically. The controller has
parameter display, parameter settings and other functions. When the unit fails, the controller displays the
fault quickly and accurately assist rapid troubleshooting, easy maintenance and management.
Schedule management
Daily timer of on-off switch time, could be set in one week cycle, to run the unit automatically, and realize
unattended operation. The programmable switch timer function of the unit, during the night, utilize the low
price electricity, to produce hot water and store in the storage device, with no staff on duty.
Building controller
UHA series air source heat pump water heater with default ModBus gateway protocol components, can
be easily connected to building control system (BAS) for centralized control, easy to implement intelligent
management, improve management efciency, and save operating cost.
Flexible application
The unit uses a modular design, enabling free combination of 1 to 16 different units, and can be combined
freely between different models to meet hot water needs of different places. When design capacity of the
units change, or phased investment of project is required, it can respond exibly.
Convenient installation
The unit is compact enough to be delivered by elevators or barrows, without any large delievering, lifting
equipment. The unit can be delievered separately, and combine to install, very simple construction. It is
conductive to shorten the construction period. The unit is installed outdoor, without dedicated machine room,
and footprint is small enough to be adapted to irregular installation space.
Backup after failure
By its industry-leading modular design, in the modular combination, each unit is backup for each other. If any
unit in a modular combination needs repair or maintenance, it will not affect the operation of other units.
Intelligent defrosting
By detecting multivariate parameters, unit accurately judge the frosting situation, and intelligently select the
best time to enter or exit the defrosting condition, to avoid endless defrosting or frequent defrosting problems.
Intelligent defrosting control design makes defrosting more quickly and thoroughly. Dual system design helps
two systems in one unit to achieve interval defrosting, and avoid excessive temperature uctuation.

General data
Notes:
1. The nominal heating capacity above is measured at outdoor environment DB/WB temperature
20ºC/15ºC, initial water tank temperature 15ºC, and nal water temperature 55ºC;
2. Nominal cycle water ow is the design value of unit heating cycle, WPD is measured at this
operation mode and water ow value;
3. Noise level is measured at noise chamber whose background noise level is 11.5 dB(A), during
actual use, due to environmental noise or other reasons, the real noise may be different;
4. All specications are subjected to change by the manufacturer without prior notice.
