Storage. 

 

Units are normally dispatched from the works fully assembled although in some cases, particularly for 
export models, certain ancillary parts may be dismantled and packed with the units. 
 
Units will be packed for protection against transit damage, only and must be stored in a dry weather-
protected area, and protected against dust, damp, builder’s debris, etc.  
 
We do not advise leaving the unit outdoors even if sheeted over. 
 
On delivery to site check over the equipment for completeness and damage, but preferably do not 
remove the packaging as this will give some degree of protection against site dust etc. Ensure, 
however, that the delivery is complete as advised on the packaging note sent with the goods. 
 

Please note that the design of many modern pumps does not always permit effective draining 
of test water. It is imperative therefore that units are protected from frost at all times, even 
before installation. Stokvis can not accept warranty claims in respect of frost damage. 
 

 

Installation. 

 

Non-packaged ‘EP’ units can be installed either on a smooth level surface, or alternatively back fixed 
to a suitable wall or other vertical structure in areas which are dry, well ventilated and free from any 
danger from frost. 
 
Once the unit has been placed in position and fixed, the following connections have to be made. 
 
1)  

Connect mains water supply to ball valve in tank. The BS1212 part 2 ball valve fitted is of high 

pressure type and the water supply should be taken from the rising main or a boosted feed. All new 
pipe work should be flushed out before connecting to the unit. 
 
2)  

Provide an overflow connection from the break tank in accordance with water byelaws. 

 
3)  

Couple the unit system connection to the system neutral point. This is normally on the return 

to the boiler/ chillers, but in the suction side of the circulating pumps if these are mounted on the 
return. 
 
The connection must be made through a union and lock shield valve, so that unit can be isolated, if 
necessary, and to aid commissioning, 
 
If the unit is supplied as part of a packaged system, then no further connections or valving are 
required. However, if the equipment has been purchased as separate components, then each 
individual item e.g. EP units and Vessels must be connected to the system as described above, and
