Trial Operation
Equipped with floats to detect the water level and an internal control circuit, the automatic
type (PUA, PNA, PSFA, TMA) pump can perform an automatic drainage operation alone by
merely connecting its cable to a power supply.
Connect the power and perform a trial operation as follows:
Note:
Allow the pump to operate a minimum of 2 seconds for each trial operation. The trial op-
eration must be completed within 1 minute.
CAUTION In case the pump exhibits an abnormal condition (such as a considerable
amount of vibration, noise, or smell), disconnect the power supply
immediately and contact the dealer where you purchased the equipment, or
Tsurumi's sales office in your area. If the pump continues to be used in the
abnormal state, it may cause current leakage, electrical shock, or fire.
(1) Direct all the floats downward.
(2) First raise the (red) stop float, then the (yellow) start
float. This will cause the pump to start.
(3) Next, return the (yellow) start float, and then the (red)
stop float to their original positions. This will cause the
pump to stop.
(4) Perform steps (2) and (3) consecutively two or more
times to verify the operation.
