Receiving Your Mini-Pack

Check Equipment Received. Inspect the unit for any shipping damage. Make sure you have received
all loose parts, as listed on the "Bill of Lading". Larger strainers, usually 2 ½ and above, are shipped
loose. Note any damages or shortages on the bill of lading prior to signing it. If the Mini-Pack is received
damaged or missing parts, it is your responsibility to notify the shipping company and file a freight claim.
Ace Boiler cannot send replacement parts for freight damaged or missing equipment as warranty items.
Permission to return goods must be received from the factory prior to shipping. Goods returned without a
Returned Goods Authorization number will not be accepted. Purchased parts are subject to replacement
only under the manufacturer's warranty. The warranty does not include the cost of labor, removal, or
installation of the warranted part.
General Installation Instructions
NOTE: All electrical and piping installation should only be accomplished by qualified personnel
following all applicable local, and state codes required for their installation.
Code Requirements: It is very important that your installation comply with all federal, state and local
codes as well as meet good industry practices as shown in publications issued by ASME, UL, ASHRAE,
ABMA, etc.
Placement: The Mini-Pack can be mounted two ways; either vertically on its base or horizontally, using
its mounting brackets for wall, ceiling or rack mounting. The Mini-Pack should be installed on a solid
foundation, preferably a concrete pad or with heavy duty bolting if mounted on a wall or ceiling. Provide
adequate clearance for normal inspection and maintenance purposes and allow tube pull clearance from
the base of the unit. A minimum clearance of 24" is recommended from all accessories for ease of
maintenance. Make sure the Mini-Pack is level, from side to side and front to back. Use metal shims if
necessary.
Piping: Control valve steam supply line shall be flushed prior to installation or with the shut-off valve
closed to isolate the Mini-Pack from the system. This is imperative to avoid any damage to the valve seat
during startup procedures AND TO AVOID WARRANTY ISSUES. All piping to and from the Mini-Pack
must be provided with adequate supports and expansion compensation so that pipe stresses are not
transmitted to the Mini-Pack. The relief valve and the double-safety solenoid valve, if supplied, should be
piped to a safe drain.
Stud Nuts: During shipment, the bonnet and shell flange nuts may loosen and should be re-tightened
before start-up. Tighten these nuts to the torques specified later in this manual. After the unit has been
in operation for a few days and periodically thereafter, check and retighten. Note: Bolting is independent
on the bonnet and shell-side flanges through the use of a threaded tube sheet flange(s). Therefore, stud
bolt nuts must be re-tightened on both sides. See Figure 1.1 for single-wall bolting arrangement and
Figure 1.2 for double-wall bolting arrangement.
