INSTALLATION
Page 3-7
SCROLL COMPRESSORS ONLY
Three phase scroll compressors (3.5, 6, 10 & 15HP) are rotation
dependant. A phase monitor is installed on these units. If the phase
monitor alarms reverse any two leads on the incoming three phase
power.
HUMIDITY SYSTEM (OPTIONAL)
Prior to operating the humidity system check the following:
1. Unit is connected to proper voltage.
2. Water supply has been connected to the rear of the unit. Humidity
water pressure should not exceed 10 PSI (69 kPa) for an atomizer
and 25 PSI (172 kPa) for a boiler. For optimal use of the atomizer
and boiler systems, inlet water pressure should not fall below 10
PSI (69 kPa) for both boilers and atomizers.
Water has a resistance level of 0.05 to 2 Mega Ohms and <2mg/L of
free chlorine. If not, the optional Demineralizer must be installed.
3. The chamber drain hose located in the compressor area should be
drained to an external drain.
4. Water line compression fi ttings on humidity panel should be secure.
5. When starting up unit the boiler will have to fi ll with water. Depending
on the water pressure and fl ow rate the low boiler water alarm could
be tripped during this process. If so, reset to continue fi lling. If alarm
continues to go off, call Cincinnati Sub-Zero.
Do not connect the steam generator
or cooling tower water to this
system. These types of water
have additives and will deplete
the demineralizer in a short period.
Use the purest water available.
NOTE
Humidity performance will be
affected if live loads are placed in
the chamber when trying to achieve
certain humidity levels.
NOTE
3.5 HP and larger scroll compressors
are equipped with crank-case
heaters. After connecting the
power, the unit must set 4 hours
before start-up to properly heat-up.
CAUTION
!
Water specifi cation 0.05 to 2 Mega
OHMS in addition to <2mg/L of free
chlorine.
CAUTION
!
Failure to maintain cartridge may
result in chloride corrosion of
stainless steel interior surfaces
which is not covered under
warranty.
WARNING
!
Maximum water inlet pressure is
10 PSI (170 kPa) for an atomizer
and 25 PS (274 kPa)I for a boiler.
Exceeding this pressure may
cause catastrophic failure of the
fi lter housing. For optimal use of
the atomizer and boiler systems,
inlet water pressure should not fall
below 10 PSI (69 kPa) for both
boilers and atomizers.
