The mains supply will be 110V AC or 230V
AC (±10%). These voltages are potentially
lethal and pose a risk of electrical shock. Refer to the
equipment label for the applicable voltage(s).
SPC Semi-Submersible Series
INTRODUCTION
The SPC series are semi-submersible single/multi-stage centrifu-
gal column pumps fitted with nylon agitators, driven by shaded
pole or fixed capacitor motors, designed for continuous operation
in chillers, coolers, vending, and general water applications to
drive coolant around a “python” chiller circuit and prevent ice
formation.

HEALTH & SAFETY
GENERAL
WARNING:
Failure to observe the safety
requirements, ratings and instructions given in this
manual can lead to serious injury, death and/or
material damage.
• Do not attempt to use the equipment for liquids with a flash
point below 38ºC.
• Do not attempt to install or operate the equipment if damage
is present.
• A suitable lock-out procedure shall be in place to prevent
inadvertent power/liquid provision.
• Do not operate the equipment without outlet pipework
connected and the pump inlet submerged in fluid.
• Do not run the pump dry for extended periods.
• Only use original equipment manufacturer parts and
accessories.
• Compliance to any local standards or regulations is the respon-
sibility of the installer, operator, or maintainer.
• Any equipment returned to the supplier must be fully cleaned,
decontaminated and accompanied by details of what fluids it
has been in contact with. A Safety Data Sheet (SDS) must be
provided for any hazardous fluids.
MECHANICAL
ELECTRICAL
Care must be taken to avoid contact/entrapment with rotating
parts. The equipment is designated a machine, it is designed to
be installed within a larger assembly which incorporates suitable
casing/guards to prevent access to the rotating parts.
• Do not insert fingers or other objects into the equipment
ports/openings.
• Where the equipment is under mains supply:
• Removable casing and guards shall remain in place at
all times.
• Installation activities shall not take place.
• Maintenance activities shall not take place unless specifi-
cally for testing operation of the equipment, and suitable
protective measures are in place.
• Where the equipment is isolated from mains supply, the risk
of contact/entrapment is considered low.
• All casing and guards, where originally fitted by the manu-
facturer, must be replaced following completion of activities
within this manual.
All electrial and hydraulic supplies must be disconnected prior
to working on the equipment. Where a plug is fitted, it must be
disconnected from the mains supply and positioned such that it
is visible during all work. If no plug is fitted, or the plug cannot be
made visible at all times, a suitable disconnect device and lockout
procedure must be implemented.
• Do not immerse any part of the motor in fluid. Refer to
Drawing and General Arrangement Sections for maximum
fluid height.
• The supply cord cannot be replaced. If damaged, the equip-
ment shall be scrapped.
The supply cord is fitted with a pre-wired plug that incorporates
an earth/ground conductor, as identified in the Wiring Color Code
section. This must be connected to a suitable earth/ground point
prior to mains supply being connected. The equipment plug is
designed to ensure this occurs and must not be altered/damaged
to prevent the connection being made.
Exposed Motor
Where the motor is supplied exposed (without a case), a
suitable enclosure must be provided to ensure a minimum IPX4
