2.1 Connection for closed loop circulation
Use pipe of a suitable bore, which will withstand a pressure up to 40psi.
The IN-let and OUT-let connections (3/8” BSP Males) are on the rear panel of the chiller (see
figures 1 and 2). Connect the unit to the external apparatus; ensure that the connections are
liquid tight. The RC should be as close as possible to the apparatus.
Connection for closed loop circulation with PRES Reservoir
The PRES Reservoir can simplify the priming of systems when operating a Closed Loop system
that has no filling port available on the suction side of the pump
Attach the PRES reservoir to the rear panel of the circulator according to the instructions
provided. Remove the 3/8” BSP straight connector from the IN-let pipe. Screw one end of the
flexihose assembly onto the IN-let pipe, then connect to the reservoir by holding the pipe in
position whilst turning the other swivel connector on the reservoir on to the other stationary end of
the flexihose. IF YOU ATTEMPT TO CONNECT IT ANY OTHER WAY THIS WILL KINK THE
HOSE.
2.2 Connection for open loop circulation
When circulating through an open tank, connect the RC inlet to the lowest point of the tank. The
RC outlet hose should be positioned as far as possible from the RC inlet hose. Unless the set
temperature of the liquid in the tank is the equal to the ambient temperature, insulate the tank.
