3. WATER QUALITY CONTROL. Lack of, as well as, improper water treatment can
damage the chilling unit. The services of competent water treatment specialist
should be obtained and their recommendations followed. It is the equipment
owner’sresponsibilitytopreventdamagefromforeignmaterialorinadequate
water treatment. See water treatment section in section 1.6 of this manual for
more information.
4. FOR AUTOMATIC FILL:
a. Always install a manual shut off valve on the make-up water supply on
the outside of the unit. When electrical power is applied to the unit and
the display is in “Standby” or “Standby Ready” open the owner supplied
shut off valve. The level switch will activate the make-up solenoid which
willopenandthewatersupplywillllthereservoirtank.Do not use
automatic ll when operating at a set point temperature below 48°F
with glycol. Dilution may occur resulting with signicant equipment
damage.
b. Whenthelevelsensorindicatesalowtanklllevelanalarmsignal
is initiated. The unit will continue to operate while in a low tank level
statebutanalarmscreenwillbedisplayeduntiltheuidllisatthe
recommended level. Access to all operating parameters will be available
through the menu function.
5. MANUAL FILL: Disconnect and lock out
the electrical power supply and remove
all necessary cover panels to access the
reservoir.Adduiddirectlytothereservoir.
Whenthepumpisrststarted,asprocess
linesarelledandairispurged,additional
uidmayberequiredtorestorethereservoirto
the correct level. Verify reservoir level via the
coolant sight glass.
6. Do not use straight deionized or RO (reverse
osmosis) water in this unit unless your unit was
specicallydesignedforusewithdeionized
water. Consult factory if not certain.
B. PROPER ROTATION (PHASING) OF SCROLL COMPRESSORS & PUMPS & FANS
1. Correct compressor(s), propeller fan(s), centrifugal blower(s) (on air-cooled units)
and pump(s) rotation is critical for unit performance and to avoid severe damage
to the compressor.
2. All compressor(s), propeller fan(s), centrifugal blower(s) (on air-cooled units)
and pump(s) will be set to rotate in the same direction during the testing process
at the factory except for units with outdoor remote condensers. The rotation of
compressors and pumps on units with remote condensers must be independently
eldcheckedforcorrectrotationbyothers.
3. After electrical installation the rotation must be checked by observing the pump
