The multi-conductor cable has 3 current carrying conductors and 1 non-
carrying conductor (Ground). Each cable conductor is made of stranded
copper, and is at least size AWG 12.
The multi-conductor flexible jacketed cable is type S, SO, ST and STO with
insulation rated for a minimum of 600 V, 75°C (140°F).
The multi-conductor cable enters the DIMAX through a flex-type, non-metallic,
¾ inch diameter strain relief. 3-4 inches of the insulated jacketed should
remain un-stripped for slippage purposes.
Each conductor is connected to the DIMAX main circuit breaker using the ring
lug. Torque each screw to 20 in-lbs.
The Ground conductor should be approximately 6 inches long in order to reach
the ground bus through the ring lug. Torque the screw as well to 20 in-lbs.
Plumbing
Requirements
Before installing the unit to an instrument that previously used tap water as a
cooling fluid, flush the instrument several times to remove any rust or scale
that has built up. The manufacturer of the instrument should be able to
recommend a cleaning fluid for their equipment.
The plumbing connections are located on the right side of the unit and are
labelled FACILITY WATER OUT (2"FPT), FACILITY WATER IN (2"FPT), MAIN
SUPPLY (2"FPT), AUXILIARY SUPPLY 1 - 3 (1"FPT), RETURN LINES 1 - 8
(1"FPT), AUXILIARY RETURN LINES 9 -11 (1"FPT), AUTOREFILL (½" FPT),
and OVERFLOW (1"FPT).
Connect the SUPPLY line to the inlet of your application. Connect the eight
MONITORED RETURN LINES and the three UNMONITORED AUXILIARY
RETURN LINES to the applicable lines (monitored or unmonitored). Connect
the FACILITY WATER IN to the cooling water supply and the FACILITY
WATER OUT to the cooling water drain or return.
Flexible tubing, if used, should be of heavy wall or reinforced construction.
The FACILITY WATER IN is subjected to the maximum pressure of the
facility cooling water. Hose connections should be securely clamped and rated
to withstand the maximum pressure of the system. Facility water supply
should not exceed 100 psi. Avoid running tubing near radiators, hot water
pipes, etc. If substantial lengths of tubing are necessary, insulation
may be required to prevent loss of cooling capacity.
