13.2.4. AIR BALANCING

A variable pulley is fitted to the motor shaft in order to adjust the blower performance to the pressure drop 

at the duct work. The pulley must be adjusted when the measured external static pressure and air volume 

(motor current draw) differ from the nominal values at the unit. As a default setting, the variable diameter 

pulley is open by 2 turns.

13.2.4.1. CASE N°1:

The  measured  air  flow  is  higher  than  the  nominal  air  flow. You  must  reduce  the  fan  rotation  speed  by 

opening the variable diameter pulley. It is imperative to adjust the pulley, otherwise the motor’s internal 

protection will trigger because of overheating taking the entire unit out of operation.

13.2.4.2. CASE N°2:

The measured air flow is lower than the nominal air flow. You must increase the fan rotation speed by 

closing the variable diameter pulley.

13.2. OPERATING CHECK LIST

13.2.1. GENERAL

Cheek for any unusual noises or vibration in the running components, particularly at the main blower.

13.2.2. PHASE ROTATION PROTECTION 

If the phase at the power supply are not correct, the phase rotation protection device will prevent the 

machine from starting.

13.2.3. ELECTRICAL

13.2.3.1. OPERATING VOLTAGE:

Recheck voltage at unit supply terminals.

13.2.3.2. CONTROL

1. 

Operate system and thermostat switches.

2. 

Check unit is wired for correct control of blower, cooling and heating modes.

3. 

Verify all sensor signal, using the controller display.

This section applies to all 

HAN

 from model 15.

13.2.5. COMPRESSOR AND REFRIGERATION SYSTEM

1. 

If outdoor air temperature is below 0°C make sure that the compressor crankcase heater has been on 

for at least one hour before starting compressor.

2. 

Running check: Start the compressor. Check for any unusual noise or vibration.

3. 

Operating Pressures: Operate the unit for at last 20 minutes and ensure that the refrigerant pressures  

are stabilised, and cheek that they are within the normal operating ranges.

4. 

Operating Temperature: Check discharge, suction and liquid temperatures.

5. 

Compressor output temperature in cooling mode should not normally exceed 105° C.

6. 

Compressor intake air superheating must be between 5° K and 12° K.
