RFD (Receiver Filter Drier)
The RFD contains desiccant to absorb moisture This
absorption is limited. Leaving the RFD installed on a
partially open system may reduce its capacity by
allowing it to absorb moisture.
The RFD is a reservoir for excess refrigerant. The
RFD also contains a sight glass in the top. A pick-up
tube extends from the bottom of the canister to the
outlet.
THERMOSTAT
For the best looking job the thermostat should be cut into a panel. (We do not
recommend installation in the insulation or in the box, as the control is not moisture
protected.) A cutting template is provided. Locate the thermostat close enough for the
"bulb" tube to reach. It is only necessary that the bulb end of the sensing tube be
installed on the plate. Use one of the mount screws for attaching the thermostat bulb
clip to the plates. Secure any excess in a coil in the refrigerated space. Do not allow
the sensing tube to contact any of the copper tubes. The sensing tube is hollow and
filled with refrigerant; avoid bending it, which could cause it to crack and leak. Excess
capillary tube should be left in the refrigerated box.
THERMOSTAT WIRING
The thermostat electrical leads are low voltage for safety. Connect the red thermostat
wires to the two terminal screws in the BG 2000 terminal box. Use the # 8 ring
terminals provided.
AC LINE CIRCUIT
A separate 30-AMPbreaker is required for the 110 volt AC circuit. A 15 amp double
breaker should be used on a 230-volt unit. We recommend following ABYC guidelines
for wire specifications and wiring procedures.
CONNECTION ACCESS
Remove the two screws in the front panel to revel the line terminal board, pump supply,
and thermostat connections.
