COSMO High-efficiency pump CPH 2.0 40
o The water in the circuit may not contain hydrocarbon derivates or aromatic
products. If an antifreeze medium must be added, its proportion may not be
more than 30%.
o The supplied thermal insulation shells should be fitted, and it must be ensured that
the condensate drain holes in the motor housing are not clogged or partially closed.
o Always use a new set of gaskets for every maintenance operation.
7.3. Installing the pump
7.3.1 Installation conditions
7.3.2 Mounting position
To ensure correct electrical, hydraulic, and mechanical installation, the
instructions given in this section of the manual must be strictly observed.
Before doing any mechanical or electrical work, the device must always be
disconnected from the power supply. Before opening the device, all indicator
lamps in the control panel must be off. Even after disconnecting the power
supply, the intermediate circuit capacitor is still at a dangerously high voltage.
Only securely wired connections are permitted. The device must be grounded
(IEC 536 Class 1, NEC, and other corresponding standards).
It must be ensured that the voltage and frequency indicated on the type label
of the CPH 2.0 pump corresponds to the on-site power supply.
The CPH 2.0 circulation pump must always be mounted with the motor shaft in
the horizontal direction. The electronic control unit is always mounted
vertically.
If the system is fitted with a non-return valve, it must be ensured that the minimum
pump pressure is always higher than the valve's closing pressure.
