 Start-up

4 Start-up

WARNING!

A ROTEX HPSU compact that is installed or 
started incorrectly may not operate properly and is 
dangerous for the health and safety of individuals.

CAUTION!

A ROTEX HPSU compact not put into operation 
properly can lead to damage to property and the envi-
ronment.

Observe the relevant regulations of technology to 
prevent creation of corrosion products and 
deposits.

Measures for desalination, softening or hardness 
stabilization are necessary, if the filling and top-up 
water have a high total hardness (> 3 mmol/l - sum 
of the calcium and magnesium concentrations, 
calculated as calcium carbonate).
– We recommend Fernox lime and corrosion pro-

tective agent 

KSK (

 

15 60 50)

.

During system operation, the water pressure at the 
pressure gauge must be checked at regular 
intervals. If necessary, readjust by refilling

4.1 Initial start-up

The ROTEX HPSU compact may be commissioned only by 

authorised and trained heating experts.

4.2 Re-commissioning

4.2.1 Requirements

CAUTION!

Setting up in frosty conditions can result in damage to 
the entire heating system.

Only set up at temperatures below 0 °C when a 
water temperature of at least 5 °C can be 
guaranteed in the hydraulic system and storage 
tank.

ROTEX recommends not operating the installation in 
extremely frosty conditions.

– The ROTEX HPSU compact is fully connected.
– The heating and hot water systems are filled and charged at 

the right pressure (see chapter 7.4).

– The storage tank is filled up to the overflow (see chapter 7.5).

4.2.2 Start-up

The safety settings of the HPSU compact hinder the 
operation of the heat pump if
– the outdoor temperature is < 12 °C and simultane-

ously

– the storage tank temperature is < 30 °C.
Without backup heater:
With an outdoor temperature < 12 °C, the storage tank 
water needs to be heated up by an external heater to 
> 30 °C.

With backup heater (BUH):

With an outdoor temperature < 12 °C and a storage tank 
temperature < 35 °C, the backup heater (BUH) is 
switched on automatically on in order to heat up the 
storage tank water to > 30 °C.

1.

Check the cold water connection and, where necessary, fill 
the potable water heat exchanger.

2.

Set the dial on the controller to the required operating mode.

3.

Turn power supply to ROTEX HPSU compact on.

4.

Wait for the start phase.

5.

After the start phase has completed, in heating mode, 
evacuate the heating system, check the installation pressure 
and adjust where necessary (max. 3 bar).

6.

Carry out a visual inspection for leaks on all joints internally. 
Seal any leaks that occur in a professional manner.

7.

If a ROTEX 

 solar system is connected, commission this 

in accordance with instructions provided. After connecting the 
ROTEX 

 solar system, make a further check on the level 

in the buffer storage tank.
