APC ACRP100, ACRP501, ACRP502, ACRP500, ACRP102, ACRP101 manual Condensate Pump

J.CONDENSATE PUMP

Factory installed and wired condensate pump shall pump at 31.99 l/h (8.45 GPH) at 3.5 m (11.5 ft) of head. Pump shall have a dual position internal float and a reservoir made of polymeric materials to prevent corrosion.

K.FILTERS

1. The standard filters shall be 30% efficient per ASHRAE Standard 52.1, UL Class 2 (MERV 8 per ASHRAE 52.2). Filters shall be EN779 G4 efficient. The 96 mm (3.75 in) deep, pleated filters shall be replaceable from the rear of the unit.

2. The optional filter shall be 85% efficient per ASHRAE Standard 52.1 (MERV 13 per ASHRAE 52.2, EN779 F7).

L.HUMIDIFIER

Humidifier shall be able to modulate capacity. The humidifier shall be self-contained, steam- generating type, factory piped and wired, with disposable cylinder and automatic solid-state control circuit. Humidifier canisters shall be replaceable. The humidifier controller shall communicate directly to the microprocessor controller and provide complete status and control at the operator interface. Humidifier shall control flush cycling and conductivity via automated controls. Humidifier shall be capable of producing up to 3 kg (6.6 lb) of steam per hour.

M.ELECTRIC REHEAT

1. Reheat elements shall be low watt density, wired for three-phase, loaded equally on all three phases and shall be electrically and thermally protected by both automatic and manual reset cutouts. Reheat capacity shall be 9 kW for chilled water and 6 kW for air-cooled.

2. Reheat coils shall be stainless steel, fin tubular construction. Heater casing shall be 0.9 mm (20 gauge) G90 galvanized steel.

3. Heater shall be provided with self-engaging electrical connectors upon installation. Heater with manually connected conductors are not acceptable.

N.TEMPERATURE AND HUMIDITY SENSORS

1. Internal Temperature Sensors: Thermister temperature sensors shall be mounted behind the front and rear doors to provide control inputs based on supply and return air temperature. Sensor accuracy shall be within +/- 1 degree F accuracy.

2. Remote Temperature Sensors: Three remote rack inlet temperature sensors shall be shipped with the unit to provide control input based on rack inlet temperature.

3. Internal Humidity Sensors: Humidity sensors shall be mounted behind both the front and rear doors and shall provide control input based on humidity in supply air. Humidifier sensor shall be +/- 3% RH accuracy full scale.

4. Water Temperature Sensors: Internal supply and return chilled water temperature sensors shall be installed into sealed wells. Wells are filled with thermal conducting heat transfer grease to provide accurate temperature sensors.

O.SELECTABLE TOP OR BOTTOM PIPING (CHILLED WATER ONLY)

1. Pipe connections: The unit equipped with field connection from either the top or bottom of the unit. Unit connections shall be made internal to the unit.

2. Pipe adapter: The unit shall include two pipe adapters that convert a 31.75 mm (1 1/4 in) NPT to a 31.75 mm (1 1/4 in) BSPT (manufactured in accordance with BS21). Pipe adapters shall ship loose with the unit for field installation where applicable.
