Installation
SAFETY FIRST! All installation shall be conducted under the applicable Health and Safety regulations in force
within that jurisdiction. Plumbing operatives shall be adequately trained and appropriately licensed to conduct the
installation. All installations will be made respective and in compliance with applicable plumbing code and any locally
published by-laws. Installation and approval of the same is subject to the appropriate ocials or representatives of the
Authority Having Jurisdiction (AHJ).
Scope of Application:
Endura® XL Grease Interceptors are designed for application in the ecient and eective separation and retention of non-
petroleum Fats, Oil and Grease as a by-product of commercial foodservice activities. The Endura® XL interceptor models are
approved and intended only for use in the specied application and shall not be installed in any manor or application except as
tested and rated.
Accessibility:
Installations shall be made in such a manner that full access for maintenance and cleaning is maintained once the interceptor is
commissioned. A zone based on a column measured 3ft out from the cover perimeter and extending
7ft vertically is recommended.
Inlet (IN) and Outlet (OUT) connections are indicated on the interceptor itself. Ensure that the interceptor is in the correct
orientation and ow in the intended direction before backlling (when in ground) or connection to the respective
drain system.
Location:
A grease interceptor should be installed as close as possible to the xtures it serves to avoid accumulation of FOG between
the source and the interceptor. Adequate provision for rodding and service access is particularly important upstream of the
interceptor. Please refer to local code requirements.
Drain lines servicing the interceptor shall be laid at a minimum ¼”per foot fall and with more gradient where possible.
This promotes good drainage ow and reduces risk of blockages.
Piping Connections:
The primary bulkhead-style connections (in-line) of Endura® XL are injection molded in Polyproylene (PP). PP does not accept
solvent weld cement and will not provide a serviceable connection. DO NOT SOLVENT WELD these drain connections.
Best practice and most codes typically require the use of Nationally or locally approved Mechanical Joint (MJ) couplings for the
connections to and from the interceptor. This method provides some exibility for any ground movement or settling that may
occur.
Flow Control:
Where required or preferred an External Flow control can be installed. In this conguration the installation has the opportunity
to meet the requirements of PDI G-101, assuming that the applicable venting and installation criterial are met (See Page 12).
Refer to the currently published version of PDI G-101 available online at www.pdionline.org for verication.
Trapping:
All connected appliances and xtures must be individually trapped by a permanently installed water seal trap or approved
equivalent, in compliance with applicable plumbing code requirements.
Venting:
The installation of the interceptor shall be vented downstream in accordance with local code requirements.
• Air Gap/ Air Break
• Flow Control Device
Indirect Connections/ Air Gap/Air Brake :
Some local jurisdictions require warewashing installations to be
made on an indirect basis incorporating an air gap.
This is to prevent the back up of contaminated waste water
into the sinks/appliances in the event of a blockage. As the ow
control device provides a restriction within the system it must be
incorporated before the indirect connection to prevent the risk of
overow occurring during high/maximum waste water discharge.
If an air gap/air break* is located within 6” of ow control device,
installation of the air intake tee is optimal.
