6.6. Factory Start-up Supervision
Seresco factory start-up supervision can be
purchased with the equipment. A factory start-up
includes several key services:
The expertise of an accomplished,
factory-trained technician who will
supervise the commissioning of the
equipment.
This Seresco representative will assist
the installing contractor with filling out
the Start-Up Report.
They will also inspect the installation to
make sure that the dehumidifier has
been properly integrated with the rest of
the equipment on the jobsite.
Finally, they can train the maintenance
personnel to operate and service the
equipment if necessary.
A factory start-up does not include installation
assistance. The installing contractor is
responsible for ensuring that the system is ready
for start-up when the Seresco representative
arrives. If the system is not ready, Seresco
reserves the right to bill the contractor for a
second visit.
When the installing contractor is confident the
system will be ready, contact the Seresco Sales
representative to schedule the start-up. Please
call at least two weeks before the desired start-up
date to prevent scheduling conflicts.
Items required for Start-Up
A service technician and a fully stocked
service vehicle.
A set of refrigerant manifold gauges.
Air balancing equipment (magnehelic
differential pressure gauge).
Volt/Amp/Ohm meters.
A digital thermometer w/clamp on
sensors.
A halogen leak detector, R-22 and a
scale.
Items to be Completed Before Start-up
Refrigerant leak-check (with halogen
leak detector) and inspect the unit for
internal concealed damage.
Level and support the dehumidifier
properly.
Install the outdoor air duct filters and
damper (if applicable).
Install the condensate P- trap and drain
lines and prime P-trap.
Pipe the remote condenser fan pressure
controls to the condenser hot gas lines
(if applicable).
Evacuate and leak-check the remote
condenser line set (if applicable).
Tighten all electrical connections and
verify that the line voltage is correct for
the unit.
Install all controls and verify that all field
wiring matches the schematic.
Fill and heat the pool and room to
design conditions.
Install the pool water piping and a flow
meter (if applicable). Purge all air from
pool lines.
A complete system air balancing.
