Site Installation
LIFTING
Whenever a condensing unit is lifted, it should be from the base and, where possible, with
all packing and protection in position. If any type of slinging is used, due care should be
taken to ensure that the slings do not crush the casework or coil.
Due note should also be made of the fact that the compressor is at one end of the unit,
and therefore the centre of gravity will also be towards that end.
If the unit is dropped, it should immediately be checked for damage.
NOTE: Keep all pipes capped during installation to prevent
pipework contamination.
POSITIONING
The condensing unit should be positioned on a stable and even base. This base should
be levelled to ensure that the compressor operates correctly without uneven internal
stresses being transmitted to the compressor support springs.
Pipework sizes and routes should be set in accordance with good refrigeration practice.
Pipework and electrical connections are readily accessible.
Where multiple units are installed, due care should be taken to avoid the discharge air
from each unit adversely affecting other units in the vicinity.
WALL MOUNTING
(CU./CUH. 1-4)
When condensing units are wall-mounted due care should be taken to choose a position
such that there will be an uninterrupted airflow over the coil under all normal
operating conditions.
It is recommended that a defrost drain tray be fitted where heat pump condensing units
are to be wall mounted to prevent ice from falling.
DEFROST DRAIN TRAY
(CUH/CUHS 1
– 4
OPTIONAL)
Attach the optional defrost drain tray to the wall mounting brackets by first attaching the 2
drain tray brackets to the wall mounting brackets using 2 M6 screws, nuts and washers.
Then attach the rear of the defrost drain tray to the wall mounting brackets using 2 M6
screws and washers. Attach the front of the defrost drain tray to the drain tray bracket
using 2 M6 screws and washers.
