Also, be sure that there is capability to fully drain the system

after cleaning. (See Fig. 23 and 24.)

Fig. 23 — 

Typical Set-up for Cleaning Process

Fig. 24 — 

Cleaning Process Using Side Stream Filter

2. Be sure to use a cleaning agent that is compatible with all sys

-

tem materials.  Be  especially  careful  if the system  contains

any  galvanized  or  aluminum  components.  Both  detergent-

dispersant and alkaline-dispersant cleaning agents are avail

-

able.

3. It is a good idea to fill the system through a water meter. This

provides  a  reference  point  for  the  future  for  loop  volume

readings, and it also establishes the correct quantity of cleaner

needed in order to get the required concentration.

4. Use a feeder/transfer pump to mix the solution and fill the

system. Circulate the cleaning system for the length of time

recommended by the cleaning agent manufacturer.
 a. After cleaning, drain the cleaning fluid and flush the sys

-

tem with fresh water.

 b. A slight amount of cleaning residue in the system can

help keep the desired, slightly alkaline, water pH of 8 to

9. Avoid a pH greater than 10, since this will adversely

affect pump seal components.

 c. A side stream filter is recommended (see Fig. 24) during

the  cleaning  process.  Filter  side  flow  rate  should  be

enough  to  filter  the  entire  water  volume  every  3  to  4

hours.  Change  filters  as  often  as  necessary  during the

cleaning process.

 d. Remove temporary bypass when cleaning is complete.

Properly  installed  and  cleaned  systems  will  rarely  need  the

strainer cleaned after the initial fill. This time interval is user-

configurable.
WATER TREATMENT
Fill the fluid loop with an inhibited antifreeze solution suitable for

the water of the area. The solution concentration must be sufficient

to protect the chilled water loop to a freeze protection (first crys

-

tals) concentration of at least 15°F (8.3°C) below the lowest de

-

sign ambient temperature. Consult the local water treatment spe

-

cialist for characteristics of system water and a recommended in

-

hibitor for the fluid loop.

Untreated or improperly treated fluid may result in corrosion, scal

-

ing, erosion, or algae. The services of a qualified water treatment

specialist should be obtained to develop and monitor a treatment

program.
FILLING THE SYSTEM
In areas where the piping or unit is exposed to 32°F (0°C) or lower

ambient temperatures, freeze-up protection is required using in

-

hibited glycol or other suitable, heat exchanger rated, corrosion-re

-

sistant antifreeze solution. Heater tapes cannot be installed on the

coils and heater tape on piping will not provide any protection. 

NOTE: Do not use automobile antifreeze, or any other fluid that is

not approved for heat exchanger duty. Only use appropriately in

-

hibited glycols, concentrated to provide  adequate protection for

the temperature considered.

If the unit is in operation year-round, add sufficient suitable inhib

-

ited antifreeze solution such as propylene or ethylene glycol to

chilled water to prevent freezing under low-ambient temperature

operating conditions. Consult a local water treatment specialist on

characteristics of water and recommended inhibitor.

The initial fill of the fluid system must accomplish three purposes:

• The  entire  piping system  must  be  filled  with water/anti

-

freeze solution.

• The pressure at the top of the system must be high enough

to vent air from the system (usually 4 psig [28 kPa] is ade

-

quate for most vents).

• The  pressure  at  all  points  in  the  system  must  be  high

enough to prevent flashing in the piping or cavitation in

the pump.

Ensure the following when filling the system:

1. Remove  temporary  bypass  piping  and  cleaning/flushing

equipment.

2. Check to make sure all drain plugs are installed.
3. Vents (if installed) at the top of the coils should be open.
4. Open the blow-down valve to flush the strainer.
5. Check for fluid leaks and repair as necessary.
Normally, a closed system needs to be filled only once. The actual

filling  process  is  generally  a  fairly  simple  procedure.  All  air

should be purged or vented from the system. Thorough venting at

the high points at the top of all coils and circulation at room tem

-

perature for several hours is recommended.

NOTE: Local codes concerning backflow devices and other pro

-

tection of the city water system should be consulted and followed

to prevent contamination of the public water supply. This is espe

-

cially important when antifreeze is used in the system.
SET WATER FLOW RATE 
Once the system is cleaned, pressurized, and filled, the  flow

rate must be set. Set the flow rate per the chiller instructions.

The chiller flow is critical for correct performance and reliabil

-

ity. The 09FC is less sensitive to off design flow rates. Flow

-

rate  should  be  set  with the  09FC unit  in  free cooling  mode.

This  mode  will  have  a  larger  pressure  drop  than  the  bypass

mode. Setting the flow in this mode assures the chiller will al

-

ways have the minimum flow required for operation.
