2.1.3 Evaporator sensor
The evaporator sensor measures the temperature of the evaporator.
The evaporator sensor should be placed in the
immediate proximity of the evaporator.
Mount the sensor head inside the evaporator cooling
fins, as shown. The sensor head must be mounted
securely to prevent being dislodged due to vibration.
For coolers fitted with a defrost heater, the evaporator
sensor should be placed as far away as possible from
the heating element, for example at the opposite end of
the evaporator.
If the evaporator sensor measures the localized heating
from the heating element, defrost cycles will terminate
before the whole evaporator has had the opportunity to
defrost.
Note
Do not use cable ties.
The head of the sensor is fragile and can be easily damaged. Using cable ties to secure
the sensor head, or sensor cable, invalidates the warranty.
2.2
Door switch
Door switches are used to detect door openings. They are SELV components that are able to create an
open and closed circuit. The Elstat enhanced door switch, and activator, are over-moulded for increased
physical protection and resistance to water ingress.
Door switch cables are available with various cable lengths.
Door switches must be used with
the corresponding activator.
Door switches are usually mounted with the door switch on the cooler and the activator on the door. Both
components must be fixed using counter sunk screws or bolts with the following characteristics:
`
Head: countersunk, maximum diameter 5.0mm (0.24in)
Thread: maximum diameter 3.0mm (0.16in)
`
The screws must be tightened to a maximum torque of 0.5Nm (0.37lb ft)
