Application Notes
Scroll Compressors
SureStart technology can be applied to most scroll
compressors as long as they fall within the correct
range of Full Load amperage rating of the listed models.
All scroll compressors have an internal equalization
mechanism. SureStart is not compatible with all Digital
scroll compressors. Consult Hyper Engineering when
using SureStart on Digital compressors.
Reciprocating & Rotary Compressors
SureStart technology can be applied to most
reciprocating and rotary compressors as long as they
fall within the correct range of Full Load amperage
rating of the listed models. Systems using these types
of compressors must equalize differential pressure
across the compressor during off cycle. SureStart is
not intended to start compressors that are under a
large differential pressure at startup. Doing so will
compromise the life of the SureStart.
Other Applications
For all other applications please consult Hyper
Engineering Technical Support
Inverter Driven Compressors
SureStart cannot be applied to inverter
driven compressors.
Schematics
Refer to the wiring diagram Figure 1, which shows how
the SureStart module should be wired into a new or
existing system. The wiring diagram illustrates SureStart
wired with a two pole contactor. SureStart can be also
be used with a one pole contactor with the contacts
located in either the L1 or L2 lines. If the compressor
is wired with a conventional start capacitor and relay,
PTCR start device, or other type of hard start kit,
those devices should be removed. Run capacitor values
must match the speci cations listed by compressor
manufacturer. To determine the speci ed run capacitor
value refer to the nameplate of the Copeland Scroll®
compressor. The compressor must be wired as a
permanent split capacitor (PSC) with the SureStart
module. SureStart is compatible with Comfort Alert®
technology. Conductor type shall be stranded copper
with a 75°C minimum temperature rating. The system
must be grounded and all applicable codes adhered to.
Application
Use of SureStart with compressors that have nameplate
RLA values above 32 amps must be tested by the
system designer to ensure that the application of the
compressor does not exceed the operating limits of
the SureStart module. SureStart can be applied with
the Copeland Scroll compressors listed in the SureStart
Compatibility Guide.
Installation Notes
WARNING!
Remove all other starters (e.g. PTC,
hardstarters). Do not swap the run and
start windings. The module shall not be
installed into an enclosure smaller than
10x8x6 inches.
Allow two minutes to discharge run
capacitor before disconnecting.
