REPLACING THE HEATER

The heat necessary for the operation of an absorption cooling

unit is supplied by an electric heater mounted in a pocket of the

boiler system. The refrigerator is equipped with one electric

heater for 120 V AC.

To replace the heater, follow these steps:

Disconnect the wall plug and for RM2510, the 12 V

DC leads to the reigniter.

Remove the protection cover.

Remove the plastic cover of the main control struc-

ture by loosening the two screws.

Disconnect the heater leads from the terminal block.

Pull off the metal hose.

With a pair of pliers, unfold the lug holding the lid of

the boiler casing and open the lid.

Remove some insulation wool so that the heater is

accessible.

Turn and lift the heater out of its pocket.

Fit the new heater into the pocket. Pull on the metal

hose around the leads.

Connect the leads and put on the plastic cover.

Put back the insulation and close the lid of the boiler.

CHECKING THE CONNECTIONS

Make sure the LP gas supply is turned on.

Check all connections in the LP gas system for gas

leaks.

Apply a non-corrosive bubble solution to all LP gas

connections. The appearance of bubbles indicates a

leak and should be repaired immediately!

CHECKING THE LP GAS PRESSURE

The LP gas pressure should be checked and readjusted if

necessary. The correct operating pressure is 11 inches of water

column. The correct place to measure the LP gas pressure is at

the test port just ahead of the burner jet.

INSPECTING THE FLUE BAFFLE

It should be reasonably clean and free of soot. Heavy soot for-

mation indicates improper functioning of the burner. The ue

and burner both require cleaning in the following manner:

Unplug the refrigerator power cord from the 120 V

AC outlet.

RM2510: Disconnect or shut off the 12 V DC power

to the refrigerator.

Shut off the gas valve.

Remove protection cover from the burner housing.

Disconnect the wire from the high voltage electrode.

Remove the burner mounting screw and then,

remove the burner assembly.

Remove the ue cap from top of ue tube and lift

out the wire and spiral bafe.

Clean the ue from the top using a ue brush. Blow-

ing compressed air into the ue will not properly

clean soot and scale out of the ue tube.

Replace spiral bafe and ue cap.

Clean burner tube with a brush. Blow out burner

with compressed air.

Before removing burner jet:

Clean burner area of soot and scale that fell out of

ue tube.

Remove the burner jet. Soak the jet in wood

alcohol and blow it out with compressed air.

Reinstall and tighten burner jet.
