O&M Instructions – Heat Pump
ALWAYS
Only use a qualified installer or qualified service person to install the door curtain. If the door curtain is
installed by an unqualified individual, a fire, electric shocks, injury, refrigerant leakage, noise and or
vibration may result and the product warranty will be invalidated.
If a heat pump model is installed in a small room, take appropriate measures to prevent the refrigerant
from exceeding the concentration limit if it leaks. Consult the dealer who supplied the heat pump outside
unit when implementing the measures. Accumulation of highly concentrated refrigerant may cause an
oxygen deficiency accident.
When transporting the door curtain, take care not to hold the bands around the packing carton. Injury
may result if the bands should break. Wear shoes with additional protective toe caps.
Check the structure is capable of supporting the weight of the unit. The designated hanging bolts M10 or
greater should be used at enough strong places to support the weight of the unit. If the strength is not
enough, the unit may fall down resulting in injury.
Check the unit will cover the full width of the door with minimum 100mm overlap each side. Mount the
unit as close to the door as possible.
Note that the maximum mounting height dimension is from fixed floor level to the discharge grille.
Refer to the charts for dimensions and weights.
Ensure that a suitable fused isolated earthed and lockable power supply is available (not supplied). The
isolator must be located at a height of between 0.6m and 1.9m above the service level. (See charts above
for rating and type). The height of the service level will be dependent upon final fixed position of door
curtain and type and size of access equipment used to service product. As a guide consider the bottom of
the air curtain to be the datum.
Provide a suitable padlock for the off-switch locking to ensure that the isolated power supply is not
accidentally switched on during installation or maintenance.
NEVER
Install the door curtain in a hazardous environment or areas where explosive atmospheres may be
present. If a combustible gas leaks and becomes concentrated around the unit a fire may occur. This
equipment is not intended to be used in hazardous environments.
Obstruct the filter (minimum recommended free space to obstruction 200mm).
Obstruct or cover the linear blade supply air grille.
