1. Important Notes on Installation
- The calorifier tank must be installed in a frost-free room
- Keep the piping as short as possible and insulate it to prevent heat loss
- These instructions should be kept readily available close to the location of the appliance
- Installation, commissioning and maintenance work must be carried out by suitably
qualified personnel in accordance with these instructions.
- For reliable and safe operation it is necessary to have the appliance regularly ser-
viced.
- No changes may be made to the calorifier. Unauthorised changes render the guaran-
tee invalid.
- Heating water and drinking water must not come into contact with each other. In par-
ticular, the process water must not be allowed to circulate via the heat exchanger.
- It is not allowed to fix the calorifier tank to the basement.

2.1 Calorifier
- Calorifier (with integrated heat exchanger) made of stainless steel Duplex
- With flange for cleaning
- Heat exchanger design varies depending on its type:
• CombiVal CR (200-1000): with integrated smooth pipe flat battery
• CombiVal CR (1250-2000): with integrated smooth pipe heat exchanger
• CombiVal CSR (300-1000): with integrated, flat/ smooth pipe heat exchanger system with enlarged heat-
ing surface
• CombiValCSR(1250-2000):withoneintegrated,triplecoiledsmooth-pipebatteryandenlargedheat-
ing surface
• MultiVal CRR (300-2000) with two integrated heat exchangers (lower unit for using solar energy, upper
unit for additional heating with oil, gas or pellet boiler). For calorifiers with volumes up to 1000 l, the lower
heat exchanger is designed as smooth pipe flat tube battery.
• MultiVal CSRR (540-2000) with two integrated heat exchangers (lower unit for using solar energy, upper
unit for heating with heat pump)
