(1) Conditions: Water entering/leaving temperature: 7/12 °C, Air inlet temperature 27/19°C DB/WB - Nominal air flow
(2) Conditions: Water entering/leaving temperature: 50/45 °C, Air inlet temperature 20°C DB - Nominal air flow
(3) At high speed with nominal air flow.
(4) Water entering/leaving temperature 90/70 °C, air inlet temperature 20 °C DB, Nominal air flow.
(5) A rectangular glass wool duct 1m50 long is placed on the blower.The measurement is taken in the room containing the blower unit.
Heat exchanger operating limits:
FWD:
*water temperature: max 100° C
*absolute service pressure: min 1 bar/max 11 bars
Accessories - Hot water coil:
*water temperature: min. +2° C/max. 100° C
*absolute service pressure: min 1 bar/max 11 bars
Expansion Tank
(Pump Package Option)
The factory installed expansion tank initial pressure should
be adjusted about 0.5 bars higher than the static pressure
applied to the chiller water inlet. The static pressure is given
by the maximum water circuit height compare to chiller
location: example: the chiller is at ground level and the
circuit loop goes from basement
(at -4m compare to chiller) to third floor at 10 metres above
ground, the static pressure to use is 10 metres of water (1
Bar) and the expansion tank initial pressure should be 1.5
bars.
The expansion tank volume has been selected for typical
loop volume. The following table summarizes the maximum
volume of the chilled water loop that can be supported by
the expansion tank at different conditions. If this maximum
volume versus the required volume of the installation is not
enough, it will be necessary to add an additional expansion
tank located on the low pressure side of the installation.

pressure of expansion tank

Tracer UC800 Set-Up
Using Tracer TU service tool, adjust the settings. Refer to
Tracer TU manual and UC800 user guide for instruction on
settings.
CAUTION!
To prevent compressor damage, do not operate
the unit until all refrigerant valves and oil-line service valves
are opened.
IMPORTANT!
A clear sight glass alone does not mean that
the system is properly charged. Also check system discharge
superheat, approach temperature and unit operating
pressures.
