2. Combo Type Heat Pump Water Heater
2.1 Features
 Safety :
1. Complete isolation between water and electricity
without electric shock problem, more safety.
2. No fuel tubes and storage, no potential danger from oil
leakage, fire, explosion, and so on.
3. No cross contamination potential, the condenser coil is
wrapped around the stainlessinner tank (MAX protection for
corrosion)
 Minimal leakage: With 15°C of ambient temperature and 43°C of average temperature in tank, the
inner tank temperature decrease only of 1,8°C.
 Quikly running operation: The unit reaches running operation, with cold start, in 203 minutes
( inlet water temperature: 15°C, outlet water temperature: 45°C, ambient
temperature: 15°C).
 Maximum outlet water temperature: 60 °C .
 Flexible installation achieves by long air inlet / outlet duct enables ducted length up to 10 meters.
NOTE: AIR INLET IS ON THE RIGHT SIDE OF THE UNIT! (IN CALOR TOP 200D MODEL IS ON LEFT SIDE)
Note: A ≤10m or A+B ≤10m
 A utomatic startup and shutdown, automatic defrosting by revising refrigerantcycle to
save the extra operation.
 According to the heat pump principle, the unit absorbs heat from outdoor air and
produce heat water thermal efficiency can be approximately 3.6 (Under the
condition A15/12 W15/45 ; A= external air temperature W= outlet hot water temperature ).
 Within the temperature range from -20 and 43 °C the unit will not be affected by night,cloudy
sky,rainevensnow weather.

Operation Mode
There are 2 operation mode in this unit:
• ECONOMY MODE : Water outlet is heated by compressor of Heat Pump; If the target setting
water is higher than max. temp (heat pump), the unit will activate heat pump firstly to max temp,
then stop heat pump and activate E-heater to continually heat water to the target temperature.
• E-HEATER MODE : Water outlet is heated only by E-heater.
2.2 Refrigerant circuit (example: Calor Top 300D(S) )
Compressor: RB233GRDC, R134a compressor, supplied by Mitsubishi.
Evaporator: copper tube and aluminum fin type heat exchanger.
EEV: “ Electronic Expansion Valve”, the opening is regulated according to the discharge air
temperature of compressor.
Fan: centrifugal fan with three speeds. The motor is supplied by Welling.
ATCO: If the water temperature is higher than 78°C, the ATCO will automatically shut off the power of
thecompressor and E-heater, and turn iton if the temperature falls down below 68°C .
TCO If the water temperature is higher than 85°C, the TCO will automatically shut offthe power of the
compressor and E-heater, it should be re-turnmanually
High Pressure Switch: When the discharge pressure of compressor is 2.76Mpa (27.5atm) or
higher, the protection switch will be triggered, and if the discharge pressure is down to 2.07MPa
(20atm), the protection switch will be recovered.

2.3 Unit structure
Note:
1. Calor Top 300D doesn’t have solar energy coil inside.
2. When ordering repair parts please always give the following information:
- Model, serial and product number.
- Parts name.
3. This unit is recommended for hot water centralized plants in multifamily
buildings, shops, restaurant, hair saloon, etc. The unit can be used in other
way, like prewarming water of heating system to realize a great energy
saving. It’s possible to integrate the unit with solar collectors (only CalorTop
300 D(S) model).
