Precautions
Before starting, make sure that the instructions shown in section 1 Introduction and Safety on
page 4 have been fully read and understood.
DANGER: Electrical hazard
The unit must not be used if the cable or the electrical compartment is damaged.
Damaged cable may only be replaced (so that danger is avoided) by the manufacturer, its
service agent or a trained professional electrician.
WARNING:
Maintenance must be done by a technician possessing the technical-professional requirements
outlined in the current regulations.
DANGER: Electrical hazard
Disconnect and lock out the power before servicing. Before starting work, check that the unit
cannot restart, even unintentionally.
WARNING:
Always wear personal protective equipment.
WARNING:
Always use suitable working tools.
WARNING:
Hot water hazard
Before draining the system, allow water to cool to at least 100 °F (38 °C), open the drain valve
(take precautions against water damage) and leave the drain valve open until servicing is
complete.
WARNING:
High Pressure Hazard
Pressure may be present in the pump body. This pressure can be relieved by loosening the pipe
connections and shifting the pump unit slightly to allow the pressurized water to escape.

Maintenance
•
Check the integrity of the supply cord every 6 months of operation; if the cable is damaged
contact Xylem or the Authorized Distributor for its replacement. Do not use the unit with
damaged cord.
•
Carefully clean the unit from outside.
•
Do not attempt to lubricate the pump. The pump is self-lubricating.

Prevent the pump from running dry.
•
Flush the system of any debris and re-purge all air from the system in the event of any water
supply interruptions in the plumbing line.
•
Prevent heavy scale build-up by keeping the hot water temperature 140 °F (60 °C) or less.
•
Don't over salt your water conditioner.
