Hot tub installation preparation 

2.1

Preparation of the place for installation and connection to 

electricity

The hot tub must be installed on a flat, sufficiently strong pad with regard to 
the load-bearing capacity of the hot tub. If the hot tub is installed outdoors, we 
recommend making a monolithic concrete pad with a minimum thickness of 10 cm. It 
is always necessary to choose the load-bearing capacity of the pad with regard to the 
dimensions and weight of the hot tub. Consult your building supervisor. The weight is 
specified in the technical description of the hot tub. 

CELTIC SPAS hot tubs are made for electrical connection of 3× 230/400 V~ alternating 
current; it is therefore necessary to use a 3× 16 A/C or D, alternatively 3× 20 A/C or D 
circuit breaker and a residual-current device corresponding to this connection. It is 
also necessary to have the cable in accordance with the applicable regulations. The 
cable must have 4 more usable meters in the place of the hot tub so that it can be 
easily routed and connected to the control unit. Do not route the cable under the 
whirlpool! PLUG & PLAY hot tubs are made for 230 V electrical connection with an 
installed circuit breaker and conductor. 

2.2

Preparation of indoor hot tub installation 

If the hot tub is installed indoors, safety precautions must be observed. The basic 
requirements for the safe operation of the hot tub are anti-slip floors and drainage 
of the installation site in the event of a water overflow. It is also necessary to 
realize that humidity will rise around the hot tub, and this may damage surrounding 
electrical appliances. We therefore recommend adapting the installation site to these 
conditions. The whirlpool should always be accessible from all sides for future 
service. If it is not sufficiently accessible during the warranty period, the owner is 
obliged to provide this access. (Sufficient access is generally considered to be at least 
60 cm from all sides of the hot tub.) 

2.3  Preparation of outdoor hot tub installation 

If the hot tub is installed outdoors, safety precautions must be observed. The basic 
requirements for the safe operation of the hot tub are anti-slip floors and drainage of 
the installation site in the event of a water overflow from the hot tub. We therefore 
recommend adapting the installation site to these conditions.
