Broughton MCSe 7.3-21, Product Manual

Page: 5 / 17

System description:
The system comprises a main indoor cooling unit, an external heat exchanger and a connecting
hose assembly.
The indoor cooling unit is fitted with an automatic condensate pump as standard.
The watercooled split system uses water as a medium to remove heat generated during the cooling
process to the external heat exchanger and then to the air. It is therefore important that the external
heat exchanger is not sited in the same area as the main indoor cooling unit.
The system has a minimum operating temperature of 15 C and a maximum operating temperature
of 35 C and comes fitted with a digital thermostat.
The watercooled split can run up to a maximum of 35m of connection hose. The external heat
exchanger should never be sited more than 5m vertically above the main unit.
Protection for the refrigeration system is provided by automatic high and low pressure safety switches
within the machine. The operation of these switches is indicated by lamps on the fascia panel.
(See page 9)
The appliance is fitted with an automatic defrost which will periodically stop the fan on the external
heat exchanger. This is indicated by the defrost lamp on the fascia panel.
During the normal cooling cycle the cooling lamp on the fascia panel will be illuminated.
The MCSe7.3 is a watercooled split portable air conditioning unit.
It is connected to a 13 Amp. 230Vac. 50Hz power supply and comes fitted with a fused uk moulded plug.
It is recommended that the supply to the machine should be protected by a 30mA RCD
Installation:
1:Connect the main cooling unit to the external heat exchanger and connect to the power
supply:
Site the main cooling unit and external heat exchanger in the desired locations. Ensure the locking
castors are engaged on the main unit before operation.
The main cooling unit, external heat exchanger and connecting hose assembly are fitted with auto-sealing
water connectors to minimise water loss during connection and disconnection. It should be noted that
a small amount water loss will occur.
The female water connectors have a sliding ring which must be pulled back to make the connection. This
will snap back into place once the connection has been made.(see page 7)
The water connectors are situated at the rear of the main cooling unit.
Fit the water connectors to the main unit. •
Fit the electrical connector to the main unit. •
Fit the clear condensate hose into the push-fit connector on the main unit. (see page 6) •
•
IT SHOULD BE NOTED THAT THE ELECTRICAL CONNECTORS ARE GENDER SPECIFIC AND WILL
ONLY CONNECT TO THE APPROPRIATE FITTINGS. PLEASE CHECK THE CORRECT PLUG IS
AT THE CORRECT END. TO DISCONNECT THE ELECTRICAL CONNECTORS DEPRESS THE GREY
LOCKING PIN AND WITHDRAW THE CONNECTOR.
Run the connecting hose assembly to the external heat exchanger in as smooth a run as possible, •
avoiding kinks and possible restrictions to water flow to a maximum of 35M.
Fit the water connectors to the external heat exchanger. •
Fit the electrical connector to the external heat exchanger. •
Fit the condensate clear hose to the hose on the external heat exchanger. •
MULTIPLE CONNECTION HOSE ASSEMBLIES CAN BE RUN IN SERIES SHOULD THIS BE REQUIRED
TO A MAXIMUM OF 35M.
TO AVOID LEAKS CHECK THAT ALL CONNECTIONS ARE FULLY HOME.
Connect the mains lead to the power supply and check that the power supply lamp is illuminated. •
