PROBLEM

CAUSE

SOLUTION

LACK OF COOLING EFFECT

1. Fouled evaporator surface Low

suction pressure will be observed.

1. Contact the local Quantech Sales

Representative.

2. Improper flow through the

evaporator.

2. Reduce flow to within chiller design

specs. See Limitations in

SECTION

4 - INSTALLATION

3. Low refrigerant charge. Low

suction pressure will be observed.

3. Check subcooling and add charge

as needed.
