Set up and operation cont’d:

  • The unit is designed to operate between 15’C and 35t. Operation outside of these temperatures could cause compressor failure and will Invalidate the warranty. If the temperature In the room is above 35t it is recommended that all the doors and windows are opened and the unit run on Fan only to reduce the temperature.
  • The appliance is fitted with a frost prevention system that controls the condenser fan. The fan will switch in and out depending on the temperature of the system. Warning! The fan is liable to start without notice.
  • Site the unit on a firm level surface and apply the castor brakes. Do not operate the machine without engaging the castor brakes.
  • Attach the 200mm exhaust duct and route to a suitable discharge point. Keep the duct as short and straight as possible. Do not operate the unit if the hose is kinked or punctured. Do not exceed the supplied length of the exhaust duct.
  • Should cold air need to be directed to a particular area fit the air discharge hoses to the front outlets and extend to the desired discharge points.
  • Do not exceed 1.25M per hose.
  • Check that the water drain tank is correctly located In it’s housing and the flexible drain hose is inserted into the tank.
  • Conned the unit to a 230Vac 50Hz power supply. Turn the ‘Fan On’ switch to ‘I’ to start the fans.
  • Turn the tooling On’ switch to ‘I’ to start the compressor. It should be noted that the compressor will not start if the fan switch is not in the on position or the ambient temperature is below 15•C. The compressor is fitted with a start delay timer and will not run for 3 minutes from activation of the cooling switch. This device Is designed to protect the compressor from repeated start-stop cycles.
  • Set the digital thermostat to the desired temperature (This is the ‘set point’). During normal running, the digital thermostat read-out shows the ambient temperature of the room. (See P6 for setting the digital thermostat)
  • Set the variable fan speed controller to the desired speed. Allow a minimum of 10 minutes for the unit to start cooling.
  • During the cooling process, the unit will produce condensate (water) which will drain into the water drain tank. Once this tank fills to a set level it will switch the compressor and fans off and illuminate the ‘Tank Full’ lamp.
  • Before removing the water drain tank, and to avoid any potentially damaging water spillage, switch the fans and cooling off and allow 5 minutes for any accumulated moisture within the machine to drain into the tank.
  • To empty the tank carefully remove it from the machine using the grab handle on the top by lifting and sliding it forwards. Do not loosen or remove the large screw cap on the front of the tank. Once the tank is emptied replace it in the housing ensuring It Is correctly located and that the flexible drain hose is inserted into the tank.
  • The machine can now be restarted.
  • Ensure the water drain tank is empty prior to transportation.
  • Do not remove the water drain tank while the machine is operating.

Setting the digital thermostat:

How to see the set point:

  • To see the set-point push and immediately release the SET key: the display will

  • The setpoint is the minimum temperature the air-conditioner will operate down to.
    show the set point value.

  • Push and immediately release the SET key or wait for 5 seconds to display the ambient room temperature.

How to change the set point:

  • Push the SET key for more than 2 seconds to change the setpoint value.
  • The appliance comes factory set at 15º C.
  • The value of the setpoint will be displayed and the ” C” LED starts blinking.
  • To change the setpoint value push the up or down arrows within 10 seconds.
  • The minimum set point is 15º C.
  • To memorise the new setpoint value push the SET key or wait for 10 seconds.

Maintenance and upkeep:
Maintenance and service work should only be carried out by competent technicians with experience and qualifications in the handling of A2L refrigerants.
The appliance should always be disconnected from the power supply before any work is carried out.
Before maintenance work is carried out all technicians should:
a) Carry out safety checks to ensure the risk of ignition is minimised.
b) Operate with controlled procedures to minimise the risk of flammable gas or vapour being present while work is carried out.
c) Ensure all staff in the local area are instructed in the nature of the work being carried out.
d) Not work in confined spaces.
e) Check work areas with an appropriate leak detector prior to and during work to minimise the risk of flammable atmospheres.
f) If any hot work is being carried out an appropriate fire extinguisher should be available to hand. Either Co2 or dry powder.
g) All possible ignition sources should be kept sufficiently far away from the work area.
h) Adequate ventilation shall be provided when breaking into the refrigeration system. The ventilation should safely disperse any released refrigerant to the external atmosphere.
i) When replacing electrical components only spare parts specified by the manufacturer shall be used.
j) Electrical work should be preceded with initial safety checks:
i) All capacitors need to be discharged in a manner that avoids sparks.
ii) No live electical components or wiring should be exposed while charging, recovering or purging the system.
iii) There is continuity of earth bonding.
k) Under no circumstances should potential sources of ignition be used in the searching for or detection of refrigerant leaks.
l) On discovery of a leak all refrigerant should be removed before a repair is carried out. The manufacturer recommends purging the circuit with an inert gas before brazing.
m) Before charging ensure the refrigeration system is earthed.

Routine checks:

  1. Check and clean the evaporator and condenser heat exchanger coils. Build-up of dust and dirt can severly affect the performance of the machine. Remove the front and rear panels and clean with compressed air.
  2. Periodically check the water tank drain mechanism is operating correctly and the drain hose is present and in good condition.
  3. Regularly inspect the mains cable and plug for signs of damage or wear. Do not operate the machine with a damaged mains cable.
  4. Check that the castors are running freely and that the breaking mechanisms are working correctly.

Troubleshooting guide:

PROBLEM POSSIBLE CAUSE SOLUTION
The machine fails to operate Power Failure Check unit is connected to the

power supply.
Check plug fuse for failure and correct 13A rating.
Check Building circuit is not overloaded.
Poor cooling performance.| ‘Tank Full’ lamp illuminated| Empty water tank.
Cooling not selected| Switch cooling on
Digital controller set below ambient temperature.| Check to set on the digital controller.
Coils dirty
Filters dirty. (where fitted)| Clean coils. See Maintenance.
Clean filters. See maintenance.
Exhaust hose too long or kinked. Exhaust outlet restricted or blocked.| Ensure maximum duct length is not exceeded. Ensure duct is run as straight as possible and is venting correctly at it’s exit point.
Air inlet grills obstructed| Remove obstruction.
Water leaking.| Clogged drain hose.| Remove blockage.
Water drain tank missing| Replace tank
Tank full and tank mechanism not working correctly.| Check tank mechanism operates correctly. Ensure the ‘Tank Full’ lamp illuminates when the mechanism is activated.
The drain hose is not correctly located in the tank.| Ensure the drain hose is located inside the tank.
The compressor stops working.| Input voltage too low. Water drain tank full.| Check line voltage.
Check water drain tank is not full.
