Intended Use - Dometic P030 Installation And Operation Manual

Intended Use


WARNING: BURN HAZARD .
Do not touch the surface of the pump during
operation or before cool down. This pump can
handle liquids up to 180
the pump to become hot and could cause burns.
Failure to obey this warning could result in death or
serious injury.

WARNING: CHEMICAL HAZARD . Failure to
obey the following warnings could result in
death or serious injury .
• Always wear protective clothing and eye protection
when handling chemicals that may be used to
operate or maintain this pump.
• Follow standard safety procedures when handling
corrosive or personally harmful materials that may be
used with this pump.
• Follow proper procedures for draining and
decontaminating the pump before performing
maintenance on it.

WARNING: LIFTING HAZARD .
This pump and associated components are heavy.
Do not attempt to lift or move the pump without
adequate support. Failure to obey this warning
could result in death or serious injury.
NOTICE: Failure to obey the following instructions
could result in damage to the pump or components, and
cause property damage.
• Keep the drive magnet and impeller assembly
away from metal chips or particles, and items with
magnetic stripes like credit cards and magnetic
computer media such as floppy discs and hard drives.
• Do not lift or move the pump without support. The
pump and components are heavy.
• Do not continue to operate the pump when unusual
noise or vibration occurs.
• Do not run the pump at less than the minimum flow.
This could lead to a pump failure.
• Do not continue to operate the pumping system
when a known leak exists.

F (82 C). This may cause
º º
• Do not operate the pump without liquid in the
casing. The exact length of time the pump can
operate dry without damage varies with operating
conditions and the environment.
• Do not start or operate the pump with a closed
suction valve.
• Do not operate the pump with a closed discharge
valve. This could lead to pump failure.
• Always provide adequate NPSHa (net positive
suction head available). It is recommended to
provide at least 24 in. (61 cm) above the NPSHr (net
positive suction head required).
• If the pump is used on variable speed drive, do
not exceed the frequency for which the pump was
designed (for example, if the pump is a 50 Hz model,
do not exceed 50 Hz).
• Ground the pump to prevent static discharge. Before
operating the pump, ensure the electrical continuity
throughout the pumping system and earth ground is
1 Ohm or less.
• Check the pump for leaks on a regular basis. If leaks
are noticed, immediately repair or replace the pump.
• Clean the pump regularly to prevent dust build up.
• Do not check the rotation of the motor without filling
the pump full of liquid, opening the suction and
discharge lines, and removing air from the lines.
• Use of a power monitor is strongly recommended for
pumps. The power monitor will stop the pump and
help prevent damage if the pump should run dry.
2 Intended Use
This Dometic Magnetic-Drive (Mag-Drive) Centrifugal
Pump (also referred to as the "pump" or the "product")
is marine grade, intended for use with sea or nonpotable
water.
Pumps are designed to encompass a wide range of
applications and configurations. The installer determines
various installation factors to fit the application, such as:
• Pump head orientation (horizontal or vertical)
