Roberts Gorden POP-ECA/PGP-ECA 015 to 0100 Commissioning, Polarity Test - 1 Ø, Louvers

SECTION 10: COMMISSIONING

SECTION 10: COMMISSIONING

Installation, service, commissioning and annual inspection of the heater must be done by a contractor qualified in the installation and service of gas or oil-fired heating equipment. Read this manual carefully before installation, commissioning, operation or service of this equipment.

WARNING

Electrical Shock Hazard Use extreme caution while commissioning.

Failure to follow these instructions can result in death or electrical shock.

2.Check the correct fuse size is fitted in the local supply isolator. See Page 8, Section 4.4.

10.1 Pre-Commission Checks

All pre-commission checks must be carried out before lighting the heater.

Ensure that the heater and all controls are suitable for the fuel, pressure and electrical supply to which they are to be connected.

10.1.1 Louvers

Where fitted, the air delivery louvers need to be set during commissioning to give the required air distribution.

WARNING

Cut Hazard

Turn off fuel and electrical supply before maintenance. Fan can start automatically at any time.

Failure to follow these instructions can result in severe injury or product damage.

10.1.2 Electrical Checks

All pre-commission checks must be carried out before commissioning the heater.

1.Check that all site wiring is connected in accordance with the appropriate wiring dia- grams on Page 20, Section 9.3 through Page 32, Section 9.15.

10.1.4 Polarity Test - 3 Ø

Voltage between each phase L1, L2 and L3 and Earth or Neutral should be approximately 230 V. Voltage between any 2 phases should be approximately 400 V. Test Neutral to Earth as single phase.

10.1.5 Fan Rotation Check

Switch on the electricity supply at the isolator and the manual switch to "fan on" (if no remote fan switch is installed, press the white button on the fan/limit thermostat). On 3 Ø heaters, check the rotation of the main fan. Rotation should be clockwise looking at the drive end. If rotation is not correct, turn off the isolator and change over any two of the incoming supply phases and recheck. It will be necessary to remove the lower front or right side panel to see fan rotation.

10.1.6 Fan Motor Overload Check

On 3 Ø belt drive heaters, check the correct settings of the fan motor overload. This should be 0.2 A above the rated current on the heater data plate. See Page 8, Section 4.4.

10.1.7 Mechanical Checks

1.Check that the flue is installed in accordance with these instructions and local regulations.

2.Check that the settings of the Combination Fan/ Limit thermostat are correct - See Page 34, Figure 13.
