Page 3: General Description
General Description. The ‘EP’ range of units are designed to pressurise sealed heating or chilled water systems, making up for losses due to leakage, etc. The units comprise a small mains break tank incorporating type ‘A’ air gap, supplied with water via a ball valve, together with one (EP 1) or two (EP 2) regenerative type pressure pumps, all enclosed in a purpose built sheet steel enclosure. -
Page 4: Storage
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. -

to suitable isolating valves be incorporated between each individual item of equipment and the system. In addition, drain cocks must be fitted to enable each individual piece of equipment to be drained down independently from the main system. Connect a switched fused single phase mains supply at 240volt 1 phase 50hz to the terminals in the control section of the unit (fused at 13amps). - Page 6 Close the isolating valve between the unit and system, and switch on the unit. The pump should run up to cut-out pressure, and stop. Crack open the system isolating valve, and observe the pressure gauge on the unit. Note the pressure at which the pump starts, and adjust this pressure if required to suit the system fill pressure determined from design data.

Page 7: Maintenance
Maintenance. Stokvis EP units have been designed to be easy to maintain, thus ensuring trouble-free operation. On two pump units the duty pump will automatically rotate per operation, to equalise wear and to exercise the standby pump. At regular intervals, but all least every six months, the following points should be checked. Bleed a little water from the system when at ambient temperature, and check that the pump cut-in and cut-out pressures are as shown in the table of settings attached. -
