Water piping Due to the variety of piping practices, it is advisable to follow the recommendations of local authorities.
They can supply the installer with the proper building and safety codes required for a safe and proper
installation.
Basically, the piping should be designed with a minimum number of bends and changes in elevation
to keep system cost down and performance up. It should contain:
1 Vibration eliminators to reduce vibration and noise transmission to the building.
2 Shutoff valves to isolate the unit from the piping system during unit servicing.
3 Manual or automatic air vent valves at the high points of the system. Drains at the low parts in the
system. The evaporator should not be the highest point in the piping system.
4 Some means of maintaining adequate system water pressure (e.g., expansion tank or regulating
valve).
5 Water temperature and pressure indicators located at the unit to aid in unit servicing.
6 A strainer or some means of removing foreign matter from the water before it enters the pump. The
strainer should be placed far enough upstream to prevent cavitation at the pump inlet (consult
pump manufacturer for recommendations). The use of a strainer will prolong pump life and help
maintain high system performance levels.
7 A strainer should also be placed in the supply water line just prior to the inlet of the evaporator. This
will aid in preventing foreign material from entering and decreasing the performance of the
evaporator.
8 The shell-and-tube evaporator has a thermostat and heating cable to prevent freeze-up down to
-28°C. Any water piping to the unit must also be protected to prevent freezing.
9 If the unit is used as a replacement chiller on a previously existing piping system, the system should
be thoroughly flushed prior to unit installation and then regular chilled water analysis and chemical
water treatment is recommended immediately at equipment start-up.
10 In the event glycol is added to the water system, as an afterthought for freeze protection, recognize
that the refrigerant suction pressure will be lower, cooling performance less, and water side
pressure drop greater. System safety devices such as freeze protection and low pressure
protection must be reset.
Prior to insulating the piping and filling the system, a preliminary leak check should be made.
Chilled water
thermostat
The EWWQ-AJYNN water-cooled chiller is equipped with the MicroTech II leaving water controller. Be
careful when working around the unit to avoid damaging lead wires and sensor cables. Check lead
wires before running the unit. Avoid rubbing the lead wires on the frame or other components. Verify
the lead wires are firmly anchored. If the sensor is removed from the well for servicing, do not wipe off
the heat conducting compound supplied in the well.
Refrigerant charge All units are designed for use with HFC-410A and are shipped with a full operating charge. The
operating charge for each unit is shown in the Physical Data Table.
Flow switch A water flow switch must be mounted in either the entering or leaving water line to insure that there
will be adequate water flow to the evaporator before the unit can start. This will safeguard against
slugging the compressors on start-up. It also serves to shut down the unit in the event that water flow
is interrupted to guard against evaporator freeze-up.
Glycol solutions Use industrial grade glycols only. Do not use an automotive grade antifreeze. Automotive antifreeze
contains inhibitors that will cause plating on the copper tubes within the chiller evaporator. The type
and handling of glycol used must be consistent with local codes.

- Pulse time 78
- Pulse time the time of the pulse time is fixed default 0 s the interval time between two pulses is proportional to the pid proportional integral derivative unit request 78
- Esie07 05 functional control 79
- Graph 2 the derivative part of the logic controls how the temperature reaches the setpoint if it is getting closer increases the time between intervals or if it is far from the setpoint decreases the time between intervals the result is having the controller act differently whenever the water temperature changes 79
- If the derivative time is increased the control will be more sensitive to temperature changes for example the derivative time can be increased when a chiller is working with a very variable load the integral time stores the memory on how the p 1 controls the temperature 79
