e) If ambient temperature is below -10℃, the chiller with both heating and cooling functions must
be used, and keep it in full-time operation;

Water cooling requirements for output optical cables:
a) Water flow requirements: QP output cable water flow is between 3.0L/min and 4.0L/min;
b) Water cooling pressure: 0.4Mpa~0.6Mpa at the water inlet;
c) Water inlet and outlet connector type: M6 to ϕ8 quick-tightening connector QP);
d) Water pipe type: outer diameter ϕ8 and inner diameter ϕ5.5(QP);
e) Cooling water direction: unidirectional. The water pipe shall be connected in strict accordance
with the water inlet and outlet direction marked on the shell.
f) Cooling water quality: deionized water, distilled water, purified water; it is recommend to
replace once a month, and the replacement period should not exceed two months.
g) PH value of cooling water: 5 ~8;
