0.4  Acceptance and storage of the pump 

  0.4.1  Acceptance of the pump 

Although the pump is delivered with great care, check the following after unpacking. 

 

  The delivered pump is in accordance with your request. 

 

  The specified accessories (enough pump oil to use the pump once; optional equipment) have 

been provided. 

 

  No parts have been damaged in transportation. 

 

  Neither screws nor nuts have become loose nor were lost in transportation. 

 

If there are any problems, contact the company from which you purchased the pump or the sales 

department of the manufacturer. 

 

  0.4.2  Environmental conditions for storage, installation and operation 

Since this pump is precisely engineered, ensure that the following conditions be satisfied during 

storage, installation and operation. 

 

 

Ambient temperature, relative humidity: 7

 ~ 40

, 85% RH or less

 

 

  Height above sea level 

during storage and installation: 1,000 m or less

 

 

 

Other conditions for storage and operation

 

 

a)  Free from corrosive and explosive gases 

 b) 

No 

condensation 

 c) 

Dust-free 

environment 

 d) 

Indoors 

 

e)  Do not place pumps on top of each other or place a pump on its side. 

 

f)  Not subject to direct sunlight 

 

g)  Far from heat sources 

 

 

Do not subject the pump to shocks or place the pump on its side. Doing so 
may damage the pump. 

 

0.5  Protective device 

The pump is provided with a single-phase 100V 50/60Hz (GCD-051X, 136X), three-phase 

200V 50/60Hz (GCD-201X) motor. 

An overload protector (manually reset thermal protector) is incorporated. 

The use of another protective device (such as an earth leakage breaker) in addition to the 

overload protector is recommended. 

 

Use the pump only at the rated voltage. Use at other than the rated voltage 
will interfere with correct operation of the overload protector, and result 
in the motor burning out, or fire.
