• Never exceed instrument maximum pressure and temperature ratings. Disconnect the
main power to the instruments during service or repair operations.
• Always operate instrument with back panel in place.

server burns from steam.
• During a test the enclosure, especially the area around test cells, can become extremely
hot and cause injury

Setting up the Instrument

Connecting Power

The 4262 instruments have one connection for input power. Connect power to the instrument
using the cord supplied with the instrument. Connect each individual instrument to a separate
circuit breaker or fuse. (A 15 Amp fuse or circuit breaker is recommended.)

Connecting Water Supply Lines

All fittings on the instruments' back panel are 1/4" female N.P.T. The included accessories kit
contains the hose connectors necessary for installation.
Refer to 84-0006 Plumbing Schematic, found in Section 6 – Drawings and Schematics, for
suggested plumbing hook-ups.
Connect the water supply line to the connector labeled WATER IN and COOLANT IN on the
rear panel of the instrument. The water must be clean and free of debris that could cause
failure of the pump or relief valve. A coarse water filter is supplied in the installation kit. If in
doubt, an additional water filter is recommended.
If the optional chiller is being used, connect the outlet port of the chiller system to the
COOLANT INLET port and the COOLANT DRAIN port to the chiller inlet port. Configure
the chiller to operate at the minimum set-point temperature (41°F, 5°C).
