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
pro
perly can lead to damage to property and the envi-
ronment.
● Observe the rele
vant regulations of technology to
prevent creation of corrosion products and
deposits.
● Mea
sures 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.
● On
ly 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 ar
e 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
te
mperature < 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 th
e 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.
