Functional Check
LEAK TEST
•
Immediately upon completion of the previous test, tilt unit towards you so the front is down. Hold for three (3)
minutes.
•
Return the unit to upright position and carefully check the reservoir tray joint for leaks. Repeat process turning
pump on back face. If leakage is found, refer to DISASSEMBLY/REASSEMBLY, Reservoir section.
GROUND RESISTANCE CHECK
WARNING
Risk of electrical shock. Be sure unit is unplugged when performing the ground resistance test.
1. Use a ground resistance meter to measure the resistance between the ground pin on the plug and the brass
manifold block (Figure 8, item 6). Contact is available through the hole where the hoses connect to the pump.
This value should not be more than 0.5 ohm.
CURRENT LEAKAGE CHECK
It will be convenient to check current leakage at this point since the unit is full and connected to a pad.
1. Measure the maximum current leakage in all combinations of heater “ON” or “OFF” and On/Standby “ON” or
Standby. Access to chassis ground for current leakage testing is available through the hole where the hose
connects to the pump. The highest reading is typically less than 100 microamperes (200 microamperes for 230
volt model). Record the highest reading.
2. Disconnect leakage meter setup.
This completes the recommended functional test for the Stryker T/Pump. If the pump passes all the requirements of
this section and the Functional Check and Safety Inspection Form, the pump should be considered operational and
suitable for return to service.
