Introduction
It is important to note that all work should be carried out by a competent person.
Solo plus is a range of self contained refrigeration units for small and large coldrooms.
The systems are pre-charged with refrigerant and pre-wired ready for installation into a coldroom with only
electrical connections to be made.
Under certain conditions a drain pipe may be required to drain any excess defrost water to an external source
Basic Description of Operation
Hot gas defrost with crankcase protection
Capillary control
Hot gas vaporisation plus 2 additional electric back up heaters with variable voltage depending on water contact.
Routine Maintenance
In order to keep the unit operating reliably and energy efficient periodical cleaning of the condenser is necessary.
(The frequency being determined by site conditions)
This operation is to be carried out with the unit turned OFF. We advise the use of an air jet blowing from inside to
the outside. If an air jet is not available then use a soft long haired brush on the outside of the condenser taking
care not to damage the fins.
Warning: Condenser fins have sharp edges so care must be taken to avoid injury

NOTE: Nomenclature “W” refers to Wall Model
As each model operates at different temperatures it will be necessary to set the required operating temperature.
