Chilled Water Coil
A single chilled water coil can be fitted as an option. This type of coil is designed to operate at 6°C
'Water On' temperature. There is no other equipment supplied with the coil and all chilled water pipe-
work and controls must be supplied by the installer to suit the equipment being installed with the
Chiller units.
The installation of the Chiller units and the refrigerant circuits must be carried out in accordance with
the condenser manufacturers instructions.
1.1.6
Filters
The standard filters supplied with the DualAir® unit are Farr 3030 grade EU4. These filters are required
to protect the cooling coil from airborne particles.
Filters must be fitted and maintained to ensure proper operation of the equipment.

Heater Operation
1.2.1
Automatic Ignition Burner
Roberts-Gordon CUHD/A range warm air heaters are fitted with an automatic ignition control which
ignites the gas and monitors for the safe operation of the burner each time the external controls call
for the heater to operate.
1.2.2
Operation - Heater Section
When the external controls call for heat, the burner operates to supply heat to the heat exchanger.
The air delivery fan will also start to run turned on by the fan relay, supplying warm air to the building.
When the external controls are satisfied they will turn off the burner leaving the fan running to cool
down the heat exchanger. When cool enough the fan thermostat will turn off the fan.
