Installation requirements

A shop with the following parameters of microclimate:
– temperature 20±5°?;
– relative humidity below 90%;
Also:
– a premise of 9m2;
– a sewer discharge at the floor level or lower with a conditional pass of at least 70mm;
– a contour of grounding, with resistance value between the grounding bolt and any of accessible parts of the device should be 0.1ohm or lower.

Operational supplies:

Demineralized water under a pressure of 4?10E5±0.5?10E5Pa(Pascal) (4±0,5 kg/cm2). Water temperature must not be higher than 20±5°?; debit of water should be 3.5 m3/hour;
Nitrogen gas, purified to the level required by GOST 9293-74 and supplied under 0,5?105Pa of pressure (0,5kg/cm2).
The power supply of the device is realized by three-phase four-wire (with a zero wire) networks of alternating electrical current with a voltage of 380V(Volt), a frequency of 50(60)Hz.
Quality standards of electrical current should meet the requirements of GOST 1.3109-87.
