OPERATING PROCEDURES
3.0. Operating Procedures
3.1. Initial Set-Up
3.1.1. Connect the power cord to a standard 115-Volt, Single Phase, 60 Hertz, or
220-Volt, 50 Hertz, grounded power source. Assure that the circuit is sized
to provide sufficient amperage as noted on the Hospi-Gard lsoClean data
plate.
3.1.2. Locate the "ON/OFF" switch on the right side of the unit. The switch is a
maintain contact rocker type.
3.1.3. Turn the Hospi-Gard lsoClean unit on by pressing downward on the raised
portion of the rocker switch. A light whirring sound will be heard as the motor
starts. Within 5 to 10 seconds, the module will start to provide clean air into the
environment.
3.2. Speed Adjustment
NOTE: The Hospi-Gard lsoClean unit is set on low at the factory (see 3.4).
3.2.1. To change speeds, remove the exhaust grille by pulling down and lifting out.
3.2.2. Turn the 3-speed switch to the desired setting.
3.2.3. Replace the exhaust grille.
3.3. Airflow Indicator
3.3.1. Locate the airflow indicator on the right side of the unit above the "ON/OFF"
switch. On high speed, the light will turn on when there is insufficient pressure,
indicating the need for a filter change. The airflow indicator should not be used as
the only guide for when a filter change is necessary. The unit should be checked
at each use to insure recommended room air changes per hour are being met.
3.3.2. The air velocity generated by the unit may be checked using an airflow
measurement device. The volume of air entering the lower intake grille should
be approximately 560 CFM (951 m
3 /h) on low, 690 CFM (1172 m 3 /h) on
medium and 800 CFM (1359 m 3 /h) on high with a new filter. See Section 9 for
the recommended airflow measurement procedure.
