System Charging Procedures

Water-Water/Glycol Cooled Systems

No field refrigerant charging is required for fluid cooled units.
The following precautions must be observed when installing
and filling the water-water/ glycol loop:
• The piping system must be cleaned prior to allowing water
or water/glycol to flow through the system.
• Glycol must be mixed with water before it is added to the
system. Use only water/glycol solution with inhibitors for
corrosion protection.
• When filling the water-water/glycol loop all air must be bled
from the piping system.
1. Open a vent valve at highest point of the system.
2. Fill the system until the solution is discharging from the
vent with minimal signs of foaming due to air in the system.

Remote Air-Cooled Systems

Remote air-cooled systems are provided with a dry nitrogen
holding charge which must be removed before piping and
charging the unit. Before charging, check the unit nameplate to
confirm the type of refrigerant to use.
Note: Refrigerant charging must be performed by a qualified
air conditioning technician.

CyberRow systems utilize R410A refrigerant. R410A is a
blended refrigerant recognized for being safer for the
environment. Refrigerants that are multi-component blends
have component parts with different volatilities that result in a
change in composition and saturation temperature as
evaporation and condensation occur. The composition of liquid
R410A refrigerant however, remains relatively constant.
CAUTION
System Contamination!
POE oil is used in systems with R410A refrigerant. POE
oil quickly absorbs moisture when exposed to air. High
POE oil moisture levels react with refrigerant to form
acid, which could result in system contamination.
Keep entire system sealed as much as possible and
minimize exposure of POE oil to outside air.
R410A operates at high pressures which must be considered
when checking the operating temperatures/pressures while
charging or troubleshooting the system. Tables are provided in
"Refrigerant Characteristics," p. 24
pressure characteristics for R410A.
Estimating Refrigerant Charge
When charging a system with R410A refrigerant it will be
necessary to weigh in the refrigerant and confirm the charge is
