Recommended Monthly Maintenance Schedule
SP Scientific recommends performing the following maintenance tasks monthly. If
additional assistance is required, please contact SP Scientific Service.
Recommended Monthly Maintenance Task Level
Inspect the product chamber and condenser door gaskets and ensure that they
are clean and free of defects (cuts, cracks, tears). If a gasket shows signs of
cracks or tears replace it immediately.
Level 1
Check the operation of the temperature-monitoring thermocouple probes. An
approximate ambient temperature reading should be observed on the
temperature display.
Level 1
Clean the interior surface of the product chamber. Remove any broken glass or
foreign material.
Level 1
Check the level and condition of the vacuum pump oil. Change oil when required.
See the vacuum pump manual supplied with your lyophilizer for instructions. Drain
some oil in the sump of the pump and compare it against a clean, unused vacuum
oil sample. If the pump oil appears discolored or cloudy, change it.
Level 1
Check for residual water in the drain lines and if evident, remove. Level 1
Ensure that all automated controls, such as shelf temperature control, operate
properly.
Level 1
Check for normal frost patterns on the compressor. Report any anomalies to your
maintenance department.
Level 1
If your unit is equipped with a water-cooled refrigeration system, check cooling
water flow and temperature, if possible. Report the low flow or high temperature
conditions to your maintenance department.
Level 1
Check air supply pressure if utilized for valve actuation. Level 1
Recommended Quarterly Maintenance Schedule
SP Scientific recommends performing the following maintenance tasks quarterly. If
additional assistance is required, please contact SP Scientific Service.
Recommended Quarterly Maintenance Task Level
Complete all items outlined on the Recommended Monthly Maintenance
Schedule.
Level 1
Check for proper operation and sealing of the condenser and product chamber
doors. Adjust as needed.
Level 1
Check the refrigeration air-cooled condensers for dust or foreign material. Clean
with a shop vacuum or air source if required.
Note: Not required for water cooled units
Level 1
Ensure that at least 10 inches (25.4 cm) of open space exists in the rear and
sides of the unit for free air movement.
Level 1
Check the vacuum system for leaks by performing a vacuum leak rate test.
Compare the original documented leak rate to the latest results. Level 1,
Level 3
Check the line voltage reading. The indicated value should be within ± 5% of the
unit’s required voltage when voltage ranges are provided or ±10% for single
voltage configurations (see Serial Tag).
Level 1
Check the oil level in each compressor, if provided with a sight glass. The level
should read to the maximum fill line. Report low-level conditions to your
maintenance department.
