cause damage to the controller.
For DPL 1100VS,

ŸFor installation above water level, use a shorter
suction pipe to reduce priming time.
ŸInstall the pump horizontally as close as possible
to the edge of the pool.
ŸProvide adequate support for the suction and
delivery pipes so that they do not weigh down on
the pump. Do not make the couplings between
the pipes too tight.
ŸDo not immerse the motor in water.
ŸTo avoid problems in suction, make a positive
slope of the suction pipe towards the pump.
ŸEnsure proper tools and equipment are used for
all connections.
ŸBefore starting the motor the first time or when
system is drained, the pump should be primed
by opening the lid of the pump leaf basket and
adding water to cover the basket.
ŸWeek l y mai n ten a nce o f the p ump i s
recommended. It is important that pump and
skimmer baskets are cleaned and any debris
removed.
ŸInstallations should be done on a firm flat base not
exposed to flooding.
ŸDo not over tighten fittings into the inlet and outlet
of the pump.
ŸFor installation below water level, fill the pump
slowly and completely open the valves in the
suction pipe and on the delivery side expel the air.
Installation, electrical connection and commissioning must be
carried out by skilled personnel in compliance with local safety
regulations. Failure to comply with these instructions causes
risk to personal safety, damages the equipment and validates
warranty.
3. INSTALLATION

Installation assembly and disassembly must be
performed by qualified personnel.
Any modification without prior authorisation relieves the
manufacturer of any kind of liability.
Ensure the power is off before connecting the wires or it
may result in electric shock or fire.
Earth terminal should be grounded or the controller and
the motor housing may be electrified.
Do not touch the main circuit terminals. The terminal
wires must not make contact with the casing of the
controller, otherwise it may result in electric shock .
