CAUTION
Excessive Water Pressure!
To prevent condenser or regulating valve damage, do not exceed 150 psi
for 30 and 60 ton units and 300 psi for 20, 25, 40 and 50 ton units
condenser water pressure.
The optional water regulating valve(s) maintains condensing pressure and
temperature by throttling water flow leaving the condenser in response to
compressor discharge pressure. Adjust the regulating valve(s) for proper operation
during start-up.
Condenser Drains.
The condenser shells can be drained by removing the drain plugs from the bottom of
the condenser heads. Also remove the vent plugs (at the top of the condenser heads)
to facilitate complete drainage.
When the unit is shipped, the condenser drain plugs are located in the control panel
along with the evaporator drain plug. The condenser drains can be piped to drain
facilities, if desired. If they are not, install the drain plugs in the condenser drain
connections on the condenser.
