Misconnection or overload could cause pump shutdown or even permanent damage.
x
Pumps might be heavy. Ask for some assistance and help if needed,
x
Pumps must not be used in the safety pipelines,
x
Pumps should not be used as a holder during welding!
x
When reassembling, care should be taken to ensure seal fit. Failing that, water could
cause damage to pumps internal parts,
x
Drains between pump motor housing and hydraulic housing must be left free (should
not be thermally insulated), as it could interfere with cooling and condensate drainage
x
Hot medium can cause burns! The motor can also reach temperatures that could cause
injury.
x
Motor housing should not be termally insulated
4.3 ELECTRICAL INSTALLATION
Electrical connection is done with connector supplied with the pump (pumps with power < 200W) or with a built in
connector for pumps with power rating above 200W (figure 4).
Fig.4
The pump has a built-in overcurrent fuse and protection, temperature protection and basic overvoltage protection. It
doesn’t need an additional thermal protection switch. The electrical power cables used should be capable of carrying
rated electrical current and should be properly fused. Ground lead connection is essential for safety. It should be
connected first. Grounding is only meant for pump safety. Pipes should be grounded separately.
