Section 2 — INSTALLATION
A. Place flange
cutouts over
5/16–18 NC
bolts installed
in mount or
accessory.
B. Rotate MODLINE 4 so
bolts capture flange, and
tighten bolts.
FIG. 2.15 – FLANGE MOUNTING PROCEDURE
PRECAUTIONS
1. DO NOT loosen or remove screws holding
front or rear bell to main casting. This would
destroy factory seal, degrading performance
and creating possible leakage problems.
2. In closed loop water systems, install relief
valve with maximum pressure rating not to
exceed 75 psi (5.1 bar) to prevent possible
damage to MODLINE 4.
FIG. 2.16 – TYPICAL WATER AND AIR FLOW CONFIGURATIONS
WATER AND AIR REQUIREMENTS
Route water and air lines before installing the
MODLINE 4. Coolant water must flow to protect
the Sensor from high ambient temperature
whether the system is operating or not.
NOTICE
The chemical content of the coolant water must
be compatible with Sil Brass (CDA 87500) of the
casting to ensure normal operating life.
Fittings are provided for standard pipe threads or
hose fittings as indicated in Fig. 2.16. Direction of
water flow is not critical. However, if the MODLINE
4 is oriented so the water fittings are not level,
attach the inlet line to the lower of the two fittings.
