Some accessories and options supersede standard product features. Your Quantech rep-
resentative will be pleased to provide assistance.
A. Microprocessor controlled, Factory installed Across-the-Line type compressor motor
starters as standard.
B. Outdoor Ambient Temperature Control
1. Low Ambient Control: Permits unit operation to 0°F ambient. Standard unit controls
to 30°F ambient.
C. Power Supply Connections:
1. Single Point or Multiple Point Disconnect: Single or Dual point Non-Fused
Disconnect(s) and lockable external handle (in compliance with Article 440-14 of
N.E.C.) can be supplied to isolate the unit power voltage for servicing. Separate ex-
ternal fusing must be supplied, by others, in the incoming power wiring, which must
comply with the National Electric Code (CE) and/or local codes.
2. Single Point Circuit Breaker: Single point Terminal Block with Circuit Breaker and
lockable external handle (in compliance with Article 440-14 of N.E.C.) can be sup-
plied to isolate power voltage for servicing. Incoming power wiring must comply with
the National Electric Code and/or local codes.
D. Control Power Transformer: Converts unit power voltage to 120-1-60 (500 VA capac-
ity). Factory-mounting includes primary and secondary wiring between the transformer
and the control panel.
E. Power Factor Correction Capacitors: Provided to correct unit compressor factors to a
0.90-0.95.
F. Condenser Coil Environmental Protection:
1. Post-Coated Dipped: Dipped-cured coating on condenser coils for seashore and
other corrosive applications (with the exception of strong alkalis, oxidizers, and wet
bromine, chlorine and fluorine in concentrations greater than 100 ppm).
G. Protective Chiller Panels (Factory or Field Mounted)
1. Louvered Panels (condenser coils only): painted steel as per remainder of unit cabi-
net, over external condenser coil faces.
2. Wire Panels (full unit): Heavy gauge, welded wire-mesh, coated to resist corrosion,
to protect con- denser coils from incidental damage and restrict unauthorized ac-
cess to internal components.
3. Louvered Panels (full unit): painted steel as per remainder of unit cabinet, to protect
condenser coils from incidental damage, visually screen internal components, and
prevent unauthorized access to internal components.
4. Louvered/Wire Panels: louvered steel panels on external condenser coils painted
as per remainder of unit cabinet. Heavy gauge, welded wire-mesh, coated to resist
corrosion, around base of machine to restrict unauthorized access.
H. Thermal Dispersion Flow Switch (Factory installed and wired in piping extension kit):
normally open, 30 bar pressure rating, stainless steel 316L construction, IP67, -4°F to
158°F ambient rating. Not available on units with remote evaporator.
