Dometic RM 4605, RM 2555, RM 2455 Maintenance, Service and Spare Parts, Ventilation of the Unit

MAINTENANCE

This appliance must be serviced by an authorised person. We recommend that an authorised service technician checks the refrigerator once a year.

The “Installation and operating instructions manual” should always be available.

Ensure that the gas safety shut-off valve is working properly.

Make sure that the ventilation openings are unobstructed.

See to it that the burner is clean and free from combustible material.

All connections in the LP gas system should be checked for gas leaks. Connections can be tested for leaks using a soap solution. DO NOT use a naked flame! If there is any suspi- cion of damage, call for an authorised service technician.

SERVICE AND SPARE PARTS

Service and spare parts are obtainable from your dealer or Dometic - consult the telephone directory.

INSTALLATION INSTRUCTIONS

The refrigerator is intended for installation in a motorhome, and the information relates to this application. A correct instal- lation is important for correct operation of the appliance. The refrigerator must be installed on a solid floor and must be level. With the vehicle carefully levelled, the refrigerator should be level both ways in the freezer compartment. Free air circulation over the fins of the cooling unit is essential.

VENTILATION OF THE UNIT

VENTILATION GRILLES

We recommend fitting the Dometic ventilation system, which is specially developed by Dometic for this purpose. The Dometic ventilation grilles permit inspection and small repairs to be carried out without the necessity of removing the refrig- erator from the recess.

If there is no outer grille at floor level where leaking gas can escape, a 40 mm hole to the outside should be made in the floor of the recess to drain any unburned gas to the outside. Fit the hole with wire mesh and an angled plate to protect it from stones, mud etc.

SIDE VENTILATION

The refrigerator unit is ventilated via two openings in the wall of the motorhome. Fresh air enters through the lower opening and warm air is discharged through the upper one.

The lower opening should be located at floor level (to allow any leaking gas to escape to the outside). The upper ventilation opening should be located above the condenser, as high as pos- sible, to ensure good ventilation. We recommend the ventila- tion kit A1625.

ROOF VENTILATION

The ventilation of the cooling unit can also be done via one opening in the wall of the motorhome and one on the roof for the roof vent.

Fresh air enters through the lower opening and warm air is discharged through the roof vent. The lower opening should be located at floor level (to allow any leaking gas to escape to the outside). We recommend the ventilation kit A1625 together with the roof vent R500.

REMOVAL OF FLUE GASES

The ventilation passage at the rear of the recess, between the outer wall of the vehicle and the refrigerator must be sealed off against the living space, so cold draughts are excluded (winter camping) and no flue gases can penetrate into the

motorhome

The flue gases are dispersed from the ventilation passage using the Dometic flueing system. The top, bottom and sides of the ventilation passage should be insulated to prevent condensa- tion and cold draughts. The ventillation passage walls must be constructed of a non combustable material.
