5. Identification of Date Code/Model Number
• Underside of the foot of the unit is a motor rating label that contains the model
number and the date of manufacture.
6. Initial Functional Test
•
Plug unit into a HI-POT tester to detect dielectric failures.
•
Plug unit into 120V outlet to determine obvious failures such as dead motor,
dead heater, dead heater light or abnormal noise.
•
Fill water and solution tanks.
. Turn on power switch, amps should be approximately 6 AMPS. Then turn on
heater switch (if present), the current will jump to approximately 9AMPS.
When the heater switch is turned “ON”, the heater light and lighted switch (if
present) should come on. If any of these conditions do not occur, check for
proper wiring (heater switch).
. To test solution flow, depress trigger until the unit’s flow indicator fills with
water and the red spinner begins to spin rapidly.
. Once proper flow has been determined, all water must be purged from the unit
using air at 5-10 PSI. The purpose of removing the water is to prevent
cracking of internal components due to fireezing and expansion.
