Accessories and options
Low sound kit
The option includes acoustic insulation for the unit's lower panels. You can use these for residential
or other similar sound-sensitive locations.
Neoprene pads isolators
Johnson Controls suggests using neoprene pads isolators for standard installations, which you
must mount in the field.
1 in. spring isolators
Level adjustable, spring and cage-type isolators for mounting under the unit base rails. They must
be field-mounted.
2 in. spring isolators
Restrained spring isolators incorporate a rugged, welded steel housing with vertical and horizontal
limit stops. Housings are designed to withstand a minimum 1.0 G accelerated force in all directions
up to 2 in. (51 mm). They are level adjustable and field-mounted.
Flow switch for special temperature difference
Vaporproof, paddle-type with 1 in. NPT connection for upright mounting in horizontal piping. The
flow switch is a standard offering for each unit with standard flow settings. An optional flow switch
is available for larger liquid temperature differences that allows a minimum flowrate down to 37
gpm (140 Lpm) with glycol applications. For applications where the single module flowrate is less
than 57 gpm (140 Lpm), select the optional low-flow type flow switch.
Water temperature sensor in a modular array
For 0070PJ, 0105PJ, and 0140PJ units, or the modular applications with a combination of multiple
modules, additional system outlet water temperature sensors, BLST 1, BLST 2, are required for
modular control. PJP two-pipe models require one system temperature sensor for one water loop,
PJS four-pipe models require two system temperature sensors for two water loops. Install the
system water temperature sensors on the customer supply header pipe. The sensors are necessary
for compressor sequencing and water side protection. Field-mounted.
Hydro kit
The external hydro kit option is suitable for water or glycol systems with an open drive air-cooled
variable speed motor. The pump kit for two-pipe, single modules is factory-mounted with 0035PJP
models. The hydro kit for other models is loose-shipped and field-mounted.
The hydro kit option is available in a single or dual pump configuration and includes an inlet
strainer, air purge, drainage valve, and trace heater in the water pipe. The second pump is for
standby use only.
Corrosion-resistant unit wire and panel enclosures are also available for the hydro kit.
