℃
b) Coolant requirements
：
1) The cooling water is pure water and it is recommended that pure drinking water can
be used.
2) To prevent the growth of mould in the water in the chiller leading to blocked pipes,
it is recommended to add ethanol at a volume ratio of 10% when refilling with pure
water.
3) When the ambient temperature around the equipment is between -10
°
C and 0
°
C,
an ethanol solution with a volume ratio of 30% must be used and changed every two
months.
4) When the ambient temperature around the equipment is below -10
°
C, a dual
system (with heating function at the same time) chiller must be used and the cooling
system must be guaranteed to run uninterrupted.
c) Output fiber optic cable water cooling requirements
：
1) Water cooling flow
：
1.7-2.0L/min
。
2) Water cooling pressure
：
Water inlet less than 0.6Mpa.
3) Type of inlet and outlet fittings
：
SMC MS-5H-6.
4) Type of water pipe
：
Outer diameter 6, inner diameter 4.
5) Cooling water direction: unidirectional, connected to the water pipe in strict
accordance with the inlet and outlet directions marked on the housing.
6) Cooling water quality: deionized water, distilled water, pure water.
7) Cooling water PH value: 5.5-9.
