To be Ordered Separately
Some essential spare parts should be ordered when purchasing a new fridge. Ask for support from your technical referent.
Instructions for use
Advantages:
- The refrigerant gas R600a (instead of the old standard R134a) is more efficient
- Longer hold-over time, with less power required (test done according to PQS protocols)
- This model has passed the freeze protection grade A test (see PQS test protocol)
- With the same capacity, it has a significant higher performance and uses less power
- There is a hidden thermostat (knob)
- No automatic alert when power is off
- Stable temperature even when the fridge is full
Remarks:
- Although R600a is a more flammable gas, no clear risks are expected.
- The fridge is PQS approved by the WHO
- Rated for use in ambient temperatures above 5°C and below 43°C
- Note: The compressor will turn off when the room temperature is between 5 - 10°C
Precautions for Use
Installation:
See manual for installation. In the user manual, it says that you have to install the appliance in a room with a volume of minimal 1 m3 per 8 g of hydrocarbon refrigerant used in the appliance, which is indicated on the rating plate. The required room volume should be:
Model | Quantities of R600a refrigerant on rating plate [kg] | Minimal volume of room required (per freezer) [m3] |
VLS 024 SDD | 0.05 | 6.25 |
VLS 154A SDD | 0.05 | 6.25 |
Door seal:
Similar as the old models from Vestfrost, Vestfrost recommends to change the complete lid if the seal is old or broken.
Thermostat:
To upgrade an even better performance in terms of temperature stability, the position of the sensor has been changed as compared to VLS-A models. The sensor is installed in wall next to the compressor compartment.
Gas:
R600a is a refrigerant gas which is a flammable. In case of leakage, the risks of explosion or fire are almost non-existent if the precautions for use have been respected (see user instructions for more details). In case of intervention on the refrigeration unit, make sure that the technician takes the necessary precautions and that an extinguisher is at hand.
