SECTION 2 - INSTALLATION
2.1 Introduction
The 8500 Series Forma Scientific non-CFC, Ultra-Low Temperature Freezers
feature front-to-back air circulation for cooler compressor temperatures, increased
performance and reliability and longer compressor life. In this unique system, ambient
air enters the front grill of the freezer and passes through the filter, condenser and
compressor housing, exiting out of the rear of the unit.
An enlarged condenser and two cooling fans contribute to better efficiency, even in
high ambient conditions. Oversize condensers also help extend compressor life.
Cleaning the air filter and condenser fins is done from the front of the unit.
Other important features of the Forma Scientific 8500 Series Freezers are:
a. Enviro-Scan Microprocessor Monitoring System
Enviro-Scan uses a digital display, audible and visual indicators and a touch
sensitive key pad to provide total control of all freezer functions. The module digitally
displays chamber temperature and control setpoint, to the nearest degree C. High and
low alarm set points are easily programmed. A back-up battery system supplies power to
the monitoring system during electrical outages.
An RS-232 port provides a computer interface and monitoring of temperatures and
alarms. A remote alarm connector is also a standard feature.
b. Non-CFC, non-HCFC and non-Flammable Refrigerants
Committed to a safer, healthier environment, Forma Scientific has phased out the
use of ozone depleting CFC (chlorofluorocarbons) in all of the company's refrigerated
products. Forma also uses non-CFC foamed-in-place urethane insulation and all
packaging used in shipping are non-CFC.
c. Peak Control System
Due to the increased demands on today's refrigeration systems, Forma Scientific has
engineered a compressor protection system called PEAK Control. In this system, a
pressure switch senses excessive compressor discharge pressure. When the discharge
