Maintenance By The Customer Service Department; Increased Generation Of Noise; Requirements For The On-Site Inlet Water Connection - Winterhalter PT ClimatePlus Supplement To The Operating Instructions

3 Servicing and maintenance
3.1 Monthly cleaning

3.2 Maintenance by the Customer Service Department

The heat exchanger must be cleaned once a year irrespective of whether there is a maintenance contract or
not. Depending on the degree of soiling, the performance of the heat exchanger will be reduced without
maintenance.
 Contact an authorised service technician for the maintenance.
4 Malfunctions

4.1 Increased generation of noise

In rare cases a loud humming noise may develop due to sound reflection. In this case we recommend the
installation of isolating buffers.
 Contact an authorised service technician for the installation.

Requirements for the on-site inlet water connection

Water quality
Water inlet temperature
Water hardness
Minimum flow pressure
Maximum input pressure 600 kPa (6.0 bar)
Flow rate
Cleaning the heat pump module:
 Slide the ventilation grill upwards and remove it.
 Clean the space behind the ventilation grill with a cleaning cloth.
 Wash the ventilation grill in the machine and then refit.
 Open the hood.
 Spray the suction channel with warm water. Use a water hose,
not a high-pressure cleaner.
 Clean the suction channel with a cleaning cloth.
The fresh water must in microbiological aspects have the quality of drinking water.
max. 60°C
We recommend a maximum hardness of 3 °dH (3.8 °e / 5.34 °TH / 0.54 mmol/l), to
prevent scaling in the machine.
The conductivity must be ≥ 200 µS/cm (128 ppm TDS).
150 kPa (1.5 bar)
