Dometic RM 2355, Installation And Operating Instructions Manual

7

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 fl ue gases can penetrate into the 

motorhome

.

The fl ue gases are dispersed from the ventilation passage using 

the Dometic fl ueing 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.

unit will only perform adequately when properly venti-

lated.

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 fl ame!

 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. 

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 fl oor 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 fi ns of the cooling unit is essential. 

VENTILATION OF THE UNIT

VENTILATION GRILLES

We recommend fi tting 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 fl oor level where leaking gas can 

escape, a 40 mm hole to the outside should be made in the 

fl oor 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 fl oor 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 fl oor level (to allow any leaking gas to escape to 

the outside). We recommend the ventilation kit A1625 together 

with the roof vent R500.
