Section 1 Introduction

Your satisfaction and safety are important to Thermo and a complete

understanding of this unit is necessary to attain these objectives.

Warning As a routine laboratory precaution, always wear safety glasses

when working with this apparatus. s

This product is not intended, nor can it be used, as a sterile or patient

connected device. In addition, this apparatus is not designed for use in

Class I, II or III locations as defined by the National Electrical Code.

Save all packing material until unit is put into service. This merchandise

was carefully packed and thoroughly inspected before leaving our factory.

Responsibility for safe delivery was assumed by the carrier upon acceptance

of the shipment; therefore, claims for loss or damage sustained in transit

must be made upon the carrier by the recipient as follows:

1. Visible Loss or amage: Note any external evidence of loss or damage

on the freight bill, or express receipt, and have it signed by the carrier's

agent. Failure to adequately describe such external evidence of loss or

damage may result in the carrier's refusing to honor your damage

claim. The form required to file such claim will be supplied by the

carrier.

2. Concealed Loss or amage: Concealed loss or damage means loss or

damage which does not become apparent until the merchandise has

been unpacked and inspected. Should either occur, make a written

request for inspection by carrier's agent within fifteen (15) days of the

delivery date; then file a claim with the carrier since the damage is the

carrier's responsibility.

If you follow the above instructions carefully, we will guarantee our full

support of your claim to be compensated for loss or concealed damage.

Introduction

The growth chamber has been commonly referred to as the standard

model 818.

The PR505750L can be converted for operation on 200V or 240V by

changing the input connections to the autotransformers (see wiring

diagram at the end of this manual).

The PR505750L/PR505755L Plant Growth Chamber has been designed

to provide the ultimate in temperature control. The user is assured of

dependable and precise performance through the use of microprocessor

technology in the temperature control circuitry. This growth chamber is

operable in the range of -10° to 50°C without illumination, and +10°C to

+50°C with illumination. These temperature ranges will meet a wide

variety of applications, such as BO determination, general incubation,

as well as the preservation of critical materials.

Note The above performance figures are based upon the following operating conditions:

- Ambient temperature of 22°C, ±3°C

- Line voltage 120V, ±5% (120V version) and 230V, ±5V (230V version)

The following test protocols have been used:

3 point measurement test: 1 thermocouple sensor in center of each shelf - 1 shelf top position, 1 shelf lowest

position, 1 shelf middle position

27 point measurement test: 9 x thermocouples on each shelf - 1 shelf top position, 1 shelf lowest position, 1

shelf middle position (based on IN 12880)

1 point measurement test: 1 thermocouple at chamber center point (temporal temperature variation

characterized by the maximum temperature difference)

The refrigeration system, defrost heater, and air circulating fan are used in

conjunction with a microprocessor controlled proportioning circuit to

achieve sensitive temperature control. An RT (Resistance Temperature

etector) located in the airstream senses any temperature deviation from

the control point, and heat is provided proportionally to maintain the

desired temperature. Regardless of what temperature is being maintained,

the compressor operates continuously. This constant operation alleviates

component failures associated with cycle type operation.

The circulating fan provides even air distribution throughout the chamber

and ensures temperature uniformity.

The program mode of PR505750L/PR505755L plant growth chamber

allows the user to program into memory 2 sets of values for time, setpoint

temperature, and light condition per day for a full week. The following is

an example of a schedule and a pictorial describing the events during that

week. A blank schedule sheet is provided toward the end of the manual for

the user to copy, then document a schedule. It is strongly recommended to

do this before any programming is performed.

The growth chamber leaves the factory with a default schedule as follows:
