Unit capacity too low. This occurs when the process

requires more heat than the unit is capable of producing.

The only option in such cases is to install a unit with an

adequate heater KW rating for the load.

Instrument defective. The instrument is designed and

manufactured exclusively by Temptek. The instrument is

life-tested and found to be field reliable. However, in the

case where the instrument is determined to be defective,

the operator must remove the assembly according to

instructions outlined in this manual and return the assembly

to the factory. The instrument is not a field serviceable

component.

4.6

PRESSURE RELIEF VALVE LEAKS

The unit has a 150 psi pressure relief valve mounted in the cooling

cylinder. If the valve is found to be leaking, the operator should

check the following:

Water supply pressure exceeds 75 psi. The unit is

designed to operate with water supply NOT exceeding

75 psi. See section 2.3 paragraph B for specific water

supply pressure requirements at corresponding setpoint

temperatures. If the plant water supply pressure exceeds 75

psi, the pressure relief valve may leak. Static water supply

pressure can be determined at the unit’s location by reading

the unit’s 0-160 PSI pressure gauges when the unit’s

motor pump is off. If the water supply pressure at the unit’s

location exceeds 75 PSI, a pressure reducing valve must be

installed in the water supply line. The factory recommended

‘regulated pressure out’ is 55 PSI. Refer to section 7.4 for

regulator installation drawing.

Back flow prevention device in water supply line. If a back flow

prevention device (check valve, pressure regulator, closed valve) is

installed in the water supply line, increased pressures from thermal

expansion are unable to move into the water supply line. This will

increase the unit’s internal pressure causing the pressure relief

valve to leak. Refer to section 7.4 for regulator installation drawing.

Valve contamination. The pressure relief valve may become

contaminated with water debris causing the valve not to close

properly. If this is the case, flushing the valve for a moment will

cleanse the seat and allow it to work properly. If flushing the valve

does not remedy the leaking, the valve must be replaced.

Extreme internal system pressure. If the internal pressure in

the Sentra unit is elevated, the pressure relief valve will leak as a

safety measure to dissipate excessive pressure. If this is the case,

the operator must determine why the system internal pressure is

excessive and correct the condition.
