The head pressure control valve (headmaster) maintains adequate condensing pres-

sure during periods of low ambient temperature. The I-Series ice makers are charged

with R404A refrigerant. The headmaster valve is set to maintain a condensing pres-

sure of 200 psig (13.8 BAR) down to an operating temperature of -20°F (-6.7° C).

Touching the lines of the headmaster will determine the flow path the headmaster is

in; condenser to receive, or bypass to receiver. Installing a gauge at the receiver out-

let valve will determine if the headmaster is functioning to maintain the proper oper-

ating pressure. It should be less than 15 psi (1.0 BAR). Less pressure indicates low

refrigerant or kinked lines.

Refer to the I Series Ice Cube Machine Service Manual & Maintenance Guide for

additional head pressure control information.
