5.6 Installation of outdoor units
•
All warnings found in chapter 5.3 Unit placement also apply.
5.6.1 Requirements
– Condensers are design for outdoor installation
– As standard, condensers can operate in temperatures as low as -20 °C
– Winter kits are available for very low ambient conditions (down to -40 °C)
– For condensers to be installed in a coastal region or an area of high corrosion,
ensure:
– The unit is supplied with epoxy or Blygold
®
coated coil
– The outdoor unit has sufficient housing and protection from the elements of the
local environment
– All pipework and interconnecting electrical cables are insulated and protected
from the environment
5.6.2 Separation
The separation between the indoor Multi -DENCO unit and the outdoor condenser
must be within the following limits for the interconnecting pipework requirements:
– No more than 35 m above the height of the indoor unit
– No more than 10 m below the height of the indoor unit
– The interconnecting pipework between the indoor and the condenser must be less
than 100 m
For more details about interconnecting pipes, please see chapter 6.
Note!
It is mandatory to connect the Multi -DENCO indoor unit to a heat rejection unit.
This is achieved typically in five different forms, depending on the version used:
– Condensers (DMOUCD)
– Condensing units (DMOUUD) (including heat pumps)
– Chiller
– Drycoolers
– Plate heat exchangers
This chapter covers only the condensers (DMOUCD). Condensing units
(DMOUUD) has a separate installation manual that can be provided on request and
is provided with the delivery of the equipment. For all other varieties or equipment
not purchased with a
Multi -DENCO unit, please refer to their independent manuals.
Outdoor condensers use exposed heat exchanger coils, which have thin metallic
fins. These fins can cause cuts to limbs.
•
Ensure cut protective PPE is worn.
•
Do not handle the condenser in the region where the coil is exposed.
