Grease Grabber Triple Play Kitchen Exhaust Pollution Control System

Fire System

Operation

This equipment is furnished with factory pre-piped

ﬁre suppression nozzles and fusible link detector

brackets. The brand of the system was speciﬁed at

time of order (Amerex or Ansul). Factory installation

is according to the Fire System manufacturers

recommendations. Field connection, tanks, controls,

fusible link detectors, and commissioning is provided

and installed, on site, by others. The AHJ may require

additional protection.

NOTE

Prior to starting the fan, remove fan tie down straps.

These are used only to prevent shipping damage.

After removing the tie down straps, the fan should

float freely on the spring isolators. Confirm that the

installation is completed as shown in the Installation

section.

Start-Up

Filter Installation (See Figure #2 on page 7)

Turn the unit on momentarily and then turn off.

Remove fan drive access cover and verify proper fan

wheel rotation. If rotation is backwards, reverse the

fan motor electrical input leads. After verifying proper

fan wheel rotation, the unit is ready for operation.

All 4 stages of ﬁlters are shipped on a separate

skid in the original factory packaging. Do not

remove packaging or install ﬁlters until just prior to

commissioning the unit.

Care must be taken to ensure ﬁlters are installed in

the proper sequence and proper direction of airﬂow

for ﬁlter stages 1, 2 & 3 (stage 4 carbon panels are not

subject to airﬂow direction).

Filter Status Indicator

As ﬁlter stages 1, 2 and 3 load with smoke and grease

particles, resistance to airﬂow increases and the

exhaust air volume decreases. Pressure switches

continuously read the resistance across each ﬁlter

stage. Each pressure switch is factory preset to

transmit an alarm signal when that stage of ﬁlter has

reached its terminal resistance and needs replacing

with new ﬁlters. This terminal resistance setting is

based on the ﬁlter manufacturers rating. The alarm

signal lights an LED located on the face panel of the

remote Filter Status Indicator Enclosure.

Open the access doors. Remove the ﬁlter

compression plates at stages 1, 2, 3 & 4. Install

ﬁlters and replace all 4 ﬁlter compression plates.

Compression plates must be in place to ensure proper

ﬁlter sealing integrity. Close and latch access doors.

NOTE

Access doors are on lift off hinges and can be easily

removed for more convenient ﬁlter servicing.

Description

Replace ﬁlters immediately after the Filter Status

Indicator light comes on. Failure to do so may

cause a reduced exhaust air volume allowing

smoke to escape into the kitchen, or may cause

ﬁlters to rupture, or both. The terminal resistance

for each stage of ﬁlters is factory set at the values

shown below. Altering these settings without ﬁrst

contacting Greenheck Fan Corp. will void the

Carbon Panel Replacement

Unlike particulate ﬁlters, technology has yet to

develop a cost-friendly method of determining when

the carbon panels need replacing. So, the industry

standard is the human sniff test. As the carbon begins

to lose its effectiveness, odor breakthrough gradually

occurs and odor concentration increases. Based on a

variety of cooking applications/installations, life of the

carbon panels can range from a few months to one

year. Replace carbon panels when odor breakthrough

is ﬁrst noticed. When replacing carbon panels,

follow the instructions in the Operation section, Filter

Replacement, Steps 2-10. There is no particular

direction of airﬂow for carbon panels.
