1.  Find a suitable indoors mounting location where the pump is close to 

the spa bath, as safely as  possible, but remains inaccessible to the 
person in the spa bath.   

a.  The pump’s suction port (inlet) must be lower than the normal 

operating bath water level to ensure proper pump priming, but 
higher than the spa bath suction to ensure correct draining.  
When emptied, the water must drain back into the spa bath as 
required by Health Department Regulations. 

b.  The discharge port (outlet) should be lower than the water level 

and the plumbing should be horizontal or rise slightly to 
prevent airlocks.  Airlocks will prevent the pump from properly 
priming.  

 

 
2.  This pump is intended for permanent installation only and must not be 

used in portable service application.  The mounting surface must be 
constructed from durable material and supported securely in a 
horizontal position. 

 

3.  A clearance of at least 7.5 cm (3”) on all sides (top, sides, front, and 

back) is required for ease of installation and air circulation.  Enclosures 
must be adequately ventilated to promote free flow of air and prevent 
condensation. 

 

4.  Provision for securing the plumbing leading to the pump must be 

considered to avoid undue stress to the pump’s connections. 

 

5.  The pump requires 220-240 Volts A.C., 10 amperes minimum, 50 Hz, 

single-phase power supply supplied through a Residual Current Device 
(RCD) with a rated tripping current not exceeding 30 mA. 

 
Above are the minimum requirements required for installing this pump.  
Additional requirements, standards, and codes, mandated by government 
agencies on specific areas where the pump will be installed, must be followed.
